A retrospective analysis of the results of ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) of 24 cases (28 lesions) of proven focal nodular hyperplasia (FNH) is presented. While US exhibited nonspecific features, CT frequently showed characteristic features: hypodensity on precontrast scans (69%), transient immediate(More)
The radiographic film wastage and the different parameters affecting this wastage were analysed for a 9-week period at a 600-bed University Hospital. An overall reject rate of 7.6% was found. The different reasons for rejection were evaluated, while retake rate, relation between working experience of the personnel, amount of rejected films and total film(More)
During a 4-year period, 53 focal echogenic liver lesions were demonstrated by sonography in 41 patients, in whom there was no evidence of metastatic origin. Most of the lesions were hemangiomas. One of the purposes of this study was to determine the characteristic ultrasound features for liver hemangioma. Small (less than 2 cm), homogeneous, echogenic,(More)
We report 4 cases of tiny aphthous ulcers of the esophagus occurring in patients with confirmed Crohn's disease of the terminal ileum and the colon. These ulcers presented as small collections of barium surrounded by a radiolucent halo, and were demonstrable on double-contrast radiographs of the esophagus. They were located in the middle and distal thirds(More)
We report five cases of cocaine smuggling, by hiding multiple drug-filled foreign bodies in the colon, either after oral ingestion or by placing them in the colon per rectum. Several smuggling methods in the gastrointestinal (GI) tract and their radiological findings on abdominal plain film are presented. Computed tomography (CT) is found to be a more(More)
Gadolinium 1,4,7,10-tetraazacyclododecane-N,N',N",N"'-tetraacetic acid (Gd-DOTA) is the first of a new class of macrocyclic paramagnetic magnetic resonance (MR) contrast agents (gadolinium cryptelates) to be used in clinical practice. Gadolinium-DOTA possesses relaxation properties similar to those of gadolinium diethylene triamine pentaacetic acid(More)
Tumors of nerves are classified into benign (schwannoma and neurofibroma) and malignant nerve sheath tumors. Schwannomas almost always occur as solitary lesions, whereas neurofibromas may occur alone or in a greater number, especially in patients with the peripheral form of von Recklinghausen's disease. Benign nerve sheath tumors often present as(More)
Three cases of calcific tendinitis occurring at an unusual site (vastus lateralis tendon) are described. Findings on conventional radiography and computed tomography together with the clinical history are characteristic for this disorder and reflect its natural evolution. The actual role of magnetic resonance imaging seems limited to excluding neoplasm and(More)
