To evaluate the application of radiofrequency ablation (RFA) as a treatment method for abdominal wall endometriosis (AWE). The characteristics of the AWE lesions in the patients were obtained using ultrasound (US). The patients received general and local anesthesia, and then, AWE lesions were divided into 1 cm3 sections visually, and each of these...

Introduction Prostate cancer is the second most commonly diagnosed cancer in males. The use of intra-prostatic fiducial markers (FM) for image-guided radiotherapy (IGRT) has become widespread due to their accuracy, relatively safe use, low cost, and reproducibility. FM provides a tool to monitor prostate position and volume changes. Many studies re...

Clinical history: A 75-year-old woman presented with a history of abdominal pain. A hypoechoic, heterogeneous solid mass at the head and uncinate of the pancreas was observed in imaging which was adjacent to the superior mesenteric artery (Figure 1-A). FNA was positive for adenocarcinoma and the patient was diagnosed with locally advanced pancreati...

Background: Different clinical and radiologic factors predict poor outcomes in patients with Coronavirus Disease 2019 (COVID-19). Thus, we aimed to investigate the performance of two separate clinical and radiologic (CT) scoring systems in detecting the prognosis of patients with COVID-19 using a low-dose protocol for CT imaging. Methods: Eighty-si...

Objectives We investigated epicardial adipose tissue thickness (EATT), carotid intima-media thickness (CIMT), and lipid profile in adult patients with epilepsy (PWE) taking anti-seizure medication(s) (ASM) and compared with those of the healthy population. We also investigated whether duration of follow-up and number of ASM(s) (mono- vs. polytherap...

Rationale and Objectives: Real-time polymerase chain reaction (RT-PCR) remains the gold standard for confirmation of Coronavirus disease 2019 (COVID-19) despite having many disadvantages. Here, we investigated the diagnostic performance of chest computed tomography (CT) as an alternative to RT-PCR in patients with clinical suspicion of COVID-19 inf...
Article
Aims We aimed to compare the clinical outcomes and imaging findings between COVID-19 patients with well-controlled diabetes and those with poorly-controlled diabetes. Methods In this retrospective single-center study, 117 patients with coexistent COVID-19 and type 2 diabetes mellitus were included. Patients were divided into two groups based on Hb...

The time course of chest computed tomography (CT) scan changes during recovery from COVID-19 has been described (1). Previous studies using repeat chest CT scans have shown that different stages could be presumed for changes in CT scan findings (2). In the early course of COVID-19 pneumonia, pulmonary CT scans could either be normal or show subtle...

Alzheimer’s disease (AD) is one of the most common type of dementia, and there is no treatment to stop or reverse its progression so far. Since AD is one of the most leading cause of death these days and the cost of caring for this disease is expected to raise dramatically, early diagnosis is really crucial. This paper represents a Computer Aided D...

Medulloblastoma is one of the common posterior fossa tumors in children. The natural history of this tumor in presymptomatic period is not well known. Widespread use of brain imaging has increased the detection of incidental brain tumors in totally asymptomatic persons. Here, we report a case of a 4-year-old boy with prenatal diagnosis of congenita...

Primary spinal hydatid cyst is considered as a very rare form of hydatid disease, which accounts for less than 0.5% to 1% of hydatid disease cases. Intramedullary hydatid cyst is extremely rare. Herein, the researchers reported on a 23-year-old male patient, who presented neck pain for 1.5 month and numbness of the right upper and lower extremities...

Müllerian ducts can form upper parts of normal female reproductive system and any failure in ductal fusion may result in to müllerian duct anomalies (MDA). We present a case of MDA and a uterus dysplasia with no evidence of cervical or upper vaginal tissue. This case showes the role of magnetic resonace imaging (MRI) on MDA diagnosis and urges the...

Background: Varicocele, one of the most common causes of sperm abnormalities in men, is the dilation of the testicular vein (the pampiniform venous plexus) by more than 2 mm. Ultrasonography is the primary imaging procedure for varicocele diagnosis. The venous diameter is evaluated using B-mode sonography, and venous reflux is assessed using color...

Functional magnetic resonance imaging (fMRI) has been widely used for pre-neurosurgical planning and may eventually become a routine pre-surgical imaging modality. The validity of fMRI for clinical application depends on various factors such as proper task selection, correct statistical analysis and threshold setting with appropriate patient cooper...

Bladder calculi, a rare condition in the pediatric population, occur most commonly as a result of either migration from the kidney or urinary stasis in the bladder. We report the case of a 3-year-old boy with recurrent urinary tract infections (UTI) secondary to bladder calculi formation on the sutures from a previous herniorrhaphy.A 3-year-old boy...

A cross-sectional case-control study was designed to compare the sagittal alignment of lumbosacral regions in two groups of patients suffering from low back pain, one with intervertebral disc pathologies and one without. To evaluate the correlation between lumbosacral sagittal alignment and disc degeneration. Changes in lumbar lordosis and pelvic p...

To compare the potential of five functional magnetic resonance imaging (fMRI) language paradigms in activating language areas in Persian-speaking volunteers in order to optimize these tasks for clinically useful protocol. 16 healthy right-handed Persian-speaking volunteers were studied. Each individual performed five tasks during the fMRI scan: wor...

To the best of our knowledge, the association between air travel and intra-tumoral hemorrhage in pediatric populations has never been described previously. We report the case of a two-and-a-half-year-old Caucasian, Iranian boy with a hemorrhaging brain tumor. He had a posterior fossa midline mass and severe hydrocephalus. He had been shunted for hy...

Neural correlates of single word reading with the use of a functional MRI (fMRI) scan have been widely studied in different languages. These study patterns of cortical activation differ in different languages. In this report we used a similar technique to study cortical activation when reading single Persian words. The subjects were comprised of ni...

Continuous ambulatory peritoneal dialysis is not a very common modality to treat Iranian children with end-stage renal disease; however, there is sometimes no choice but to offer this therapy to salvage the patient. Obviously, promotion in each program needs re-evaluation to find the pitfalls. Therefore, a nation-wide survey on pediatric continuous...
