OBJECTIVE To determine the sensitivity and specificity of clinical tests for detecting focal lesions in a prospective blinded study. METHODS 46 patients with a focal cerebral hemisphere lesion without obvious focal signs and 19 controls with normal imaging were examined using a battery of clinical tests. Examiners were blinded to the diagnosis. The sensitivity, specificity, and positive and n...

The delayed-onset focal dystonia is a rare sequela of cerebrovascular disease or diffuse cerebral hypoxic damage. The responsible lesion sites for the dystonia are variable and the pathogenesis is uncertain. We describe two children with delayed-onset focal dystonia as a complication of perinatal anoxia. The intervals between hypoxic insult and onset of dystonia were 6 years in one and 3 in the...

Hepatocyte specific contrast agents including gadoxetic acid and gadobenate dimeglumine are very useful to diagnose various benign and malignant focal hepatic lesions and even helpful to estimate hepatic functional reservoir. The far delayed phase image referred to as the hepatobiliary phase makes the sensitivity of detection for malignant focal hepatic lesions increased, but specificity of mal...

OBJECTIVE To determine common imaging findings of hepatic epithelioid hemangioendothelioma on magnetic resonance images. MATERIALS AND METHODS A search was made of three institutional databases between January 2000 and August 2012. Seven patients (mean age, 47 years; range, 21-66 years; 6 women) with pathology-confirmed diagnosis of hepatic epithelioid hemangioendothelioma who had undergone m...

A 63-year-old woman had gone to the emergency room several times for recurring episodes of headaches, tachycardia with palpitations, anxiety and sweating in the context of hypertensive crisis. High levels of adrenaline, noradrenaline, metanephrine and normetanephrine were found in urine. RM detected a hypervascular 5 cm in size right adrenal mass in contact with the inferior cava vein compatibl...

A 25 year old healthy female presented with a two month history of nausea, epigastric pain that worsened after eating and diarrhea. Complete blood count and biochemistry panel results were unremarkable and liver serology was negative. Abdominal ultrasonography (US) showed a solid lesion in the right upper quadrant, suspicious for a gastric mass. Liver protocol multiphase computed tomography (CT...
