    ABSTRACT: Abstract Portal hypertension, a major complication of hepatic fibrosis, can affect the stiffness of the spleen. Objective To suggest normal values of spleen stiffness determined by acoustic radiation force impulse imaging in healthy children and to compare measurements using two different US probes. Materials and methods In a prospective study, 60 healthy children between 1 day and 14 years of age were assigned to four age groups with 15 children in each. Measurements were performed using two transducers (convex 4C1 and linear 9L4), and 10 measurements were obtained in each child, 5 with each probe. Results The mean splenic shear wave velocities were 2.17 m/s (SD 0.35, 95% CI 2.08–2.26) with the 4C1 probe and 2.15 m/s (SD 0.23, 95% CI 2.09–2.21) with the 9L4 probe (not significant). Conclusion We found normal values for spleen stiffness with no difference in the mean values obtained using two types of US transducers, but with higher variability using a convex compared to a linear transducer.

    ABSTRACT: The foundation for the usefulness of any diagnostic test should be that it is both reliable and accurate in its clinical diagnosis. In this article we present the second of a two-part series on validity and reliability, discussing the assessment of reliability among raters of diagnostic tests and between diagnostics tests themselves. To examine reproducibility (reliability) among raters of diagnostic tests we present the calculation of two statistical procedures: (1) the kappa coefficient statistic when presented with categorical data for the presence or absence of a clinical diagnosis and (2) the intraclass correlation coefficient (ICC) for continuously scaled data among raters. The accuracy among diagnostic tests (i.e. their interchangeability) can be evaluated by application of (1) a Bland-Altman plot procedure (with its 95% limits of agreement) and (2) the Passing-Bablok regression procedure (for the identification and evaluation of systematic and proportional differences). When deciding whether to select a diagnostic test one must evaluate its ability to provide more precise information than a gold standard test, and whether in clinical practice it would be more beneficial for patients to adopt it.

    ABSTRACT: Neonates with congenital diaphragmatic hernia (CDH) often require placement of lines and tubes for supportive therapy. The resulting altered anatomy can result in diagnostic errors when interpreting the location of support lines and tubes such as UVCs (umbilical venous catheters). The purpose of this study was to evaluate the effect of CDH on UVC position and to evaluate the accuracy at which radiologists describe the position on chest radiographs. During a 5-year period, 406 chest radiographs performed within 7 days of birth in infants with congenital diaphragmatic hernia were identified and reviewed for the following data: presence of UVC, location of catheter tip (cavoatrial junction, intracardiac, intrahepatic or umbilical vein), and location of CDH (right or left). The radiologic report of the UVC tip location for each case was then reviewed individually to determine the adequacy of interpretation. Inadequate reports were classified as incorrect (the wrong location of the catheter tip was reported), no mention (the location of the catheter tip was in a suboptimal location but not mentioned), and not specified (the precise location of the catheter tip was not clearly stated in the report when the tip was in a suboptimal location). A total of 60 infants were identified as having CDH (56 on the left, 4 on the right). The most common location for an incorrectly placed UVC was the contralateral chest, accounting for 26.7% (16/60) of the infants, followed by an abdominal intrahepatic location (16.7%) and the umbilical vein (8.3%). Thirty percent (120/406) of the chest radiograph reports were found to be inadequate regarding the interpretation of the location of the catheter tip. The majority of the inadequate reports (48/406, 11.8%) did not specify when the catheter tip was in a suboptimal location. In 37 reports (9.1%), the location of the catheter tip was reported incorrectly, and no mention of the catheter location was made in 35 reports (8.6%). The location of an UVC in an infant with Bochdalek hernia can pose a diagnostic challenge because of the altered anatomy and change in the expected course of the catheter. Familiarity with the altered anatomy and vigilance of the various abnormal locations in which UVCs can be placed can help optimize management for the child and reduce morbidity and mortality.

    ABSTRACT: Congenital pulmonary airway malformation (CPAM) is classified into pathologically different types. These types are sometimes distinguishable by fetal lung MRI and are usually observed as higher-signal lesions on T2-weighted images than normal lung. We describe a case of unusual CPAM resembling neoplasms, with a lower signal than is found in normal lung. Histopathology showed a large number of mucogenic cells but found no evidence that could explain this feature on fetal MRI. An unusual low-signal mass associated with a pulmonary cyst in fetal lung on MRI may suggest an unusual type 1 CPAM.

    ABSTRACT: Background Granulocyte colony-stimulating factors (G-CSF) speed recovery from chemotherapy-induced myelosuppression but the marrow stimulation they cause can interfere with interpretation of F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET) exams. Objective To assess the frequency of interfering G-CSF-induced bone marrow activity on FDG PET imaging in children and young adults with Ewing sarcoma and rhabdomyosarcoma and to define an interval between G-CSF administration and FDG PET imaging that limits marrow interference. Materials and methods Blinded, retrospective review of FDG PET exams performed in patients treated with long-acting G-CSF as part of their chemotherapeutic regimen. Exams were subjectively scored by two reviewers (R1 and R2) who assessed the level of marrow uptake of FDG and measured standardized uptake values in the marrow, liver, spleen and blood pool. FDG PET findings were correlated with time since G-CSF administration and with blood cell counts. Results Thirty-eight FDG PET exams performed in 17 patients were reviewed with 47.4% (18/38) of exams having marrow uptake of FDG sufficient to interfere with image interpretation. Primary predictors of marrow uptake of FDG were patient age (P = 0.0037) and time since G-CSF exposure (P = 0.0028 for subjective marrow uptake of FDG, P = 0.008 [R1] and P = 0.004 [R2] for measured maximum standardized uptake value (SUVmax)). The median interval between G-CSF administration and PET imaging in cases with marrow activity considered normal or not likely to interfere was 19.5 days (range: 7–55 days). Conclusion In pediatric and young adult patients with Ewing sarcoma and rhabdomyosarcoma, an interval of 20 days between administration of the long-acting form of G-CSF and FDG PET imaging should limit interference by stimulated marrow.

    ABSTRACT: Background Radiographic bone age determination is part of the routine evaluation of suspected growth disorders. Simplicity and low cost are its major advantages, but although the effective dose of ionizing radiation is low, it should be taken into consideration given its cumulative effect. Objectives To assess the chronological ultrasonographic emergence of the ossification centers of the hand and wrist. Materials and methods Cross-sectional study of healthy patients ages 1 to 24 months (n = 498) from Buenos Aires, Argentina. All patients underwent ultrasonographic evaluation of the left hand and wrist to identify the different bone nuclei; a subgroup of infants had their nuclei measured (n = 228). Results Girls showed an earlier emergence of the evaluated nuclei and a trend to a greater size than age-matched boys. Size-for-age relation showed linear increase. Carpal bones (capitate and hamate) were the first to appear, as early as from the first 3 months of life, an age gap not thoroughly present on the radiographic atlas developed by Greulich and Pyle. The distal epiphysis of the radius and the second metacarpophalangeal joint (index finger) followed in order of emergence. The proximal epiphysis of the first metacarpal bone (thumb) was the last to emerge and was infrequently found on boys at age 24 months. Overall, these findings are in accordance with the radiographic atlas. An ultrasonography atlas of the left hand and wrist was outlined for girls and boys. Conclusion Conventional ultrasonography allows proper identification of the ossification centers of the hand and wrist and may become an innocuous follow-up tool for patients with growth disorders.

    ABSTRACT: The kidneys are the most commonly injured genitourinary organ in children following blunt abdominal trauma. Though the retroperitoneal location affords the kidneys some protection from the forces experienced in blunt abdominal trauma, the kidneys are at greater risk of injury when a disease process exposes them from their normal shielded location. In such cases, the injuries may appear to be disproportionate in relation to the severity of the trauma history, confusing the imaging findings. Recognition of both the underlying disease process as well as the manifestations of acute trauma is important; therefore, we present a pictorial essay of traumatized kidneys in children with pre-existing renal abnormalities.

    ABSTRACT: “Measure what is measurable, and make measurable what is not so.” It was the 17th century when Galileo Galilei, father of the scientific method, made this well-known statement. With this sentence, Galilei told us to avoid subjective, qualitative evaluations of the world around us. Rather, he advised to make our observations as objective as possible, independent from the observer. He first recognized that human beings greatly differ from one another and that, in the evaluation of a given entity, a spectrum of opinions is inevitable. In an era in which technical instruments were far to come, such a situation made the science of nature very unscientific.In medicine, the uncertainty recognized by Galilei was further formalized by Alexander Pope, who in 1732 wondered “Who shall decide when doctors disagree?” This question must have been a very common one in Pope’s day, because medical practice at that time was based largely on tradition and opinion, not science. Regarding the evaluation of ...

    ABSTRACT: Background: Performing micturating cystourethrography (MCUG) in young children with recurrent urinary tract infection is controversial with discrepancy among the major guidelines. Objective: Previous studies have shown that a normal dimercaptosuccinic acid (DMSA) scintigraphy may avoid the need of performing MCUG for detecting vesicoureteric reflux in children with first febrile UTI. However, the role of DMSA for ruling out vesicoureteric reflux in children with recurrent urinary tract infections has not been studied. Materials and methods: Approval from institutional ethical review committee was sought and the requirement of informed consent was waived. A total of 50 children under the age of 10 years with recurrent urinary tract infections underwent MCUG scan within 3 months of DMSA scan from January 2011 to September 2012 at our institution. Diagnosis of recurrent urinary tract infections and grading of VUR was according to previously established standards. Abnormalities on DMSA scan – scarring, hydronephrosis and reduced differential renal function – were compared with presence of vesicoureteric reflux on MCUG. Results: High-grade vesicoureteric reflux was noted on MCUG in 22 (44%) cases. The findings on DMSA included hydronephrosis and scarring in 25 (50%) and 25 (50%) cases, respectively. Abnormalities on DMSA scan for detecting the presence of high-grade vesicoureteric reflux on MCUG examination had sensitivity, specificity, positive and negative predictive values of 95.45%, 35.71%, 53.85% and 90.91%, respectively. The positive and negative likelihood ratios were 1.48 and 0.13 respectively. Conclusion: DMSA scan had high overall sensitivity and negative predictive value with a low negative likelihood ratio for ruling out high-grade VUR on MCUG, which may obviate the need of invasive MCUG along with its associated drawbacks.

    ABSTRACT: This article questions the scientific justification of ingrained radiologic practices exemplified by size measurements of childhood solid tumours. This is approached by a critical review of staging systems from a selection of paediatric oncological treatment protocols. Local staging remains size-dependent for some tumour types. The consequent stage assignment can significantly influence treatment intensity. Still, the protocols tend not to give precise guidance on how to perform scans and standardise measurements. Also, they do not estimate or account for the inevitable variability in measurements. Counts and measurements of lung nodules are, within some tumour groups, used for diagnosis of metastatic disease. There is, however, no evidence that nodule size is a useful discriminator of benign and malignant lung nodules. The efficacy of imaging depends chiefly on observations being precise, accurate and valid for the desired diagnostic purpose. Because measurements without estimates of their errors are meaningless, studies of variability dependent on tumour shape and location, imaging device and observer need to be encouraged. Reproducible observations make good candidates for staging parameters if they have prognostic validity and at the same time show little covariation with (thereby adding new information to) the existing staging system. The lack of scientific rigour has made the validity of size measurement very difficult to assess. Action is needed, the most important being radiologists' active contribution in development of oncological staging systems, attention to standardisation, knowledge about errors in measurement and protection against undue influence of such errors in the staging of the individual child.

    ABSTRACT: MRI is an important additional tool in the diagnostic work-up of children with congenital heart disease. This review aims to summarise the role MRI has in this patient population. Echocardiography remains the main diagnostic tool in congenital heart disease. In specific situations, MRI is used for anatomical imaging of congenital heart disease. This includes detailed assessment of intracardiac anatomy with 2-D and 3-D sequences. MRI is particularly useful for assessment of retrosternal structures in the heart and for imaging large vessel anatomy. Functional assessment includes assessment of ventricular function using 2-D cine techniques. Of particular interest in congenital heart disease is assessment of right and single ventricular function. Two-dimensional and newer 3-D techniques to quantify flow in these patients are or will soon become an integral part of quantification of shunt size, valve function and complex flow patterns in large vessels. More advanced uses of MRI include imaging of cardiovascular function during stress and tissue characterisation of the myocardium. Techniques used for this purpose need further validation before they can become part of the daily routine of MRI assessment of congenital heart disease.

    ABSTRACT: In the early days of cardiac surgery, the pretreatment multidisciplinary discussion involved a presentation of the case history and diagnostic imaging by the clinical cardiologist. At this time, most, if not all, cardiac imaging techniques were in the hands of the cardiologist. If the radiologist made a report, this was done relatively late in the clinical process and only concerned the perioperative radiographs. In recent years, multidisciplinary decision-making in the context of a Heart Team has gained an increasingly important role in the process of decision-making with regard to the available therapy options in individual patients. Nevertheless, the concept of the Heart Team is still evolving. The minimal requirements for the Heart Team include the presence of the attending cardiologist, an interventional cardiologist and a cardiac surgeon. Those members of the Heart Team should be aware of the local possibilities, should correctly make conclusions about the available data and should put this information into the clinical context and preference of the patient. In addition, in areas where expertise in cardiac imaging such as CT and MRI is relevant, this would explicitly require expertise of the Heart Team in these specific areas, most often by involving a radiologist, to provide the optimal joint treatment strategy recommendation.
