MRI for clinically suspected appendicitis during pregnancy.
ABSTRACT OBJECTIVE: The purpose of this study was to evaluate whether MRI can be used to accurately diagnose or exclude appendicitis in pregnant patients with clinically suspected appendicitis. CONCLUSION: Our results suggest that MRI is helpful in the examination and diagnosis of acute appendicitis in pregnant patients. MRI may therefore be a good alternative to CT in pregnant patients for whom sonographic findings are nondiagnostic.

ABSTRACT: Abdominal pain presenting itself during pregnancy may be multifactorial, requiring immediate attention and care. In cases of intractable pain without obstetrical condition, surgical abdominal exploration is widely advised. However, we present a case where a 30-year-old, gravida 1, para 0, female complained of persistent right abdominal pain during her 25th week of pregnancy. Ultrasound revealed a right upper quadrant cystic mass and magnetic resonance imaging was arranged with compatible findings. Final impression of appendiceal abscess was determined. Broad-spectrum antibiotics were administered and the patient was discharged in stable condition after 10 days of conservative treatment. She delivered a healthy baby boy at her 40th week of gestation uneventfully.Journal of the Chinese Medical Association 09/2007; 70(8):345-7. · 0.79 Impact Factor

ABSTRACT: To establish the value of breathhold magnetic resonance imaging (MRI) in the diagnosis of acute appendicitis. Over a 14-month period, 138 patients clinically suspected of having appendicitis were evaluated prospectively with MRI and comprised the study group. Fast turbo spin-echo breathhold T1, T2 and T2 fat suppression sequences were used in coronal and axial planes. The imaging results were recorded separately and subsequently correlated with clinical, radiological and histopathological follow-up. The effect of imaging strategies in patients suspected of appendicitis on hospital resources was calculated. Sixty-two of the 138 patients had a histopathologically proven appendicitis. MRI determined appendicitis in 63 patients, with one examination being false positive. The resulting sensitivity and specificity were 100% and 99%, respectively. MRI showed an alternative diagnosis in 41 of the 75 remaining patients. In 22 of the remaining 34 patients, a normal appendix was depicted with MRI. In two patients, where MRI showed no appendicitis, an alternative diagnosis or normal appendix, an unnecessary appendectomy was performed. The overall effect of using MRI in patients suspected of appendicitis on the use of hospital resources could have been a net saving between 55,746 euros and 72,534 euros. MRI has a high accuracy in detecting and excluding appendicitis, an alternative diagnosis or showing the normal appendix, and can be a valuable and cost-effective tool in the workup of patients clinically suspected of having appendicitis.European Radiology 02/2009; 19(5):1175-83. · 3.22 Impact Factor

ABSTRACT: Frances A Hampson, Ashley S ShawDepartment of Radiology, Addenbrooke’s Hospital, Cambridge, UKAbstract: ‘The acute abdomen’ is one of the most frequent reasons for presentation to the emergency department. There are a multitude of potential causes. Imaging plays a vital role in making an accurate and timely diagnosis, which in turn reduces morbidity and mortality. Plain abdominal radiography has traditionally been considered a fundamental part of the initial assessment of acute abdominal pain. However, with the increasing availability of computed tomography, ultrasound, and magnetic resonance imaging, the role of the plain abdominal radiograph has been increasingly questioned and its use is dwindling. During the course of this review, we will describe the current guidelines for the use of the plain abdominal radiograph and assess its potential diagnostic yield. We will also discuss its current applications in the context of the acute abdomen both in general and in a number of frequently encountered conditions and illustrate when other imaging modalities would be better employed.Keywords: acute abdomen, abdominal radiographReports in Medical Imaging. 01/2010;
