BACKGROUND AND PURPOSE To assess patient radiation exposure in comprehensive stroke imaging using multidetector row CT (MDCT) combining standard CT of the head, cerebral perfusion (CTP), and CT angiography (CTA) studies. METHODS Examination protocols for CT and CTA of cerebral and cervical vessels, as well as CTP were simulated using a Somatom Sensation(More)
AIMS The myocardial effect of tonically released nitric oxide (NO) in humans is still not known. We tested the hypothesis that low-dose NO exerts positive effects on left ventricular (LV) function. METHODS AND RESULTS Twelve healthy volunteers, 26+/-4 years, were enrolled in this study. Magnetic resonance imaging was used to precisely measure the direct(More)
INTRODUCTION Circumscript, progressing lipoatrophy at the insulin injection sites is an unexplained, however rare condition in diabetes mellitus. CASE PRESENTATION We report a case of severe localised lipoatrophy developing during insulin pump-treatment (continuous subcutaneous insulin infusion) with the insulin analogue lispro (Humalog®) in a woman with(More)
BACKGROUND Imaging studies of bones in patients with sensory deficits are scarce. AIM To investigate bone MR images of the lower limb in diabetic patients with severe sensory polyneuropathy, and in control subjects without sensory deficits. METHODS Routine T1 weighted and T2-fat-suppressed-STIR-sequences without contrast media were performed of the(More)
We report a case of a 74-year-old male, who presented with an acute ST elevation posterior wall myocardial infarction (MI) 21 years following revascularization with three saphenous vein grafts (SVGs) to the left and right coronary arteries. In coronary angiography (CAG), the dilated SVG to the first marginal branch of the circumflex artery appeared only(More)
BACKGROUND The diagnosis of Sudeck's syndrome stage 1 (nowadays termed complex regional pain syndrome I, abbreviated CRPS I) is based on clinical features, namely swelling and pain in a limb. Plain X-ray may be normal. In the absence of pain sensitivity, e.g. in diabetic neuropathy, CRPS I of the foot can be mistaken for Charcot's foot stage 0 (so-called(More)
INTRODUCTION Intramural dissection of the esophagus is a rare disorder characterized by a lesion between the submucosa and mucosa dividing the esophagus into a false and true lumen. The etiology of esophageal dissection remains uncertain but it affects predominantly women in their seventies and eighties. Symptoms may include uncharacteristic ones such as(More)
INTRODUCTION Tenosynovial giant cell tumors are benign tumors of uncertain pathogenesis. They occur in the joints, tendons and synovial bursas. Due to a high recurrence rate of up to 50%, some authors call a giant cell tumor a semimalignant tumor. To date, less than 10 cases of tenosynovial giant cell tumor of the ankle have been published in the(More)
INTRODUCTION Primary neoplastic lesions presenting with a mucocele of the appendix are very rare and can be divided into benign variants of mucinous adenomas or cystadenomas, mucinous tumours of uncertain malignant potential or mucinous cystadenocarcinomas. Most of these tumourous mucoceles are asymptomatic and are found incidentally. The major complication(More)
Dosing of enzyme replacement therapy (ERT) for Gaucher disease type 1 is still a subject of debate and varies from 15 to 130 U/kg/mo, making a huge economic difference of US $70 000 to US $380 000 (€55 000-300 000) per patient per year. To investigate whether this difference in dosing ultimately translates into a different response, we retrospectively(More)
