Incidental splenic lesions are frequently encountered at imaging performed for unrelated causes. Splenic cysts, hemangiomas, and lymphomatous involvement are the most frequently encountered entities. Computed tomography and sonography are commonly used for initial evaluation with magnetic resonance imaging reserved as a useful problem-solving tool for(More)
The unique dual blood supply of the liver makes it one of the common sites for various vascular neoplastic and non-neoplastic diseases. Increasing use of multiphase contrast-enhanced computed tomography (CT) and dynamic magnetic resonance imaging (MRI) has led to increased identification of numerous non-neoplastic vascular entities apart from already(More)
Minimally invasive gastrointestinal, genitourinary, and gynecological procedures are widely used in the clinical practice for diagnostic and therapeutic purposes. Complications both minor and major are not uncommon with these procedures. Imaging plays an important role in the detection and optimal management of these complications. Familiarity with the(More)
Inflammatory myofibroblastic tumour (IMFT) is a relatively uncommon neoplasm with unpredictable malignant potential known to occur anywhere in the body. IMFT involving the omentum is a very rare entity with less than 15 cases reported so far. We report a case of omental IMFT in a 15-year-old girl who presented with multiple peritoneal masses on imaging and(More)
Detection and quantification of hepatic iron with dual-echo gradient recalled echo (GRE) has been proposed as a rapid alternative to other magnetic resonance imaging (MRI) techniques. Co-existing steatosis and T1 weighting are limitations. This study assesses the accuracy of routine dual-echo GRE. Between 2010 and 2013, 109 consecutive patients underwent(More)
Triad of leukoencephalopathy, cerebral calcifications and cysts (LCC) is a recently reported rare disease named 'Labrune syndrome' after the first case was reported in 1996 by Labrune et al. Herein, we report a case of a 36-year-old man with mild right-sided weakness and seizures for 5 years. CT of brain revealed extensive calcification involving bilateral(More)
OBJECTIVES To investigate and compare the knowledge of radiation dose and risk incurred in common radiology examinations among radiology residents, fellows, staff radiologists and technologists. METHODS A questionnaire containing 17 multiple choice questions was administered to all residents, technologists, fellows and staff radiologists of the department(More)
103 patients of head injury, with a Glasgow coma scale (GCS) score of 8 or less, were studied prospectively. GCS score, brain stem reflexes, motor score, reaction level scale, and Glasgow Liege scale were evaluated as prognostic variables. Linear logistic regression analysis was used to obtain coefficients of these variables and mathematical formulae(More)
Bifid mandibular condyle is an uncommon entity with a controversial etiology. It can be developmental or acquired and rarely may be associated with temporomandibular joint (TMJ) ankylosis. Although the patient may be asymptomatic, the radiologist should be aware of this entity and its clinical implications. We report two cases of BMC, one developmental and(More)
