OBJECTIVE The aim of our study was to compare the signal-to-noise ratio and the diagnostic accuracy of moving-table MR angiography of the peripheral arteries with body coil and dedicated phased array coil systems. SUBJECTS AND METHODS Forty patients were examined with digital subtraction angiography and moving-table MR angiography with a 1.5-T MR imaging(More)
OBJECTIVE To establish whether ADC and total choline were significantly different between cervical tumors with different histological characteristics (type, degree of differentiation, presence or absence of lymphovascular invasion, lymph-node involvement) in order to establish their role as predictive biomarkers. METHODS 62 patients with stage 1 cervical(More)
Supravalvular aortic stenosis (SVAS) can be inherited as an isolated autosomal dominant trait or can be a component manifestation of the Williams syndrome. Some consider the Williams syndrome to be due to more severe expression of the gene defect that causes isolated SVAS. We describe a family with isolated SVAS that is the largest thoroughly studied family(More)
OBJECTIVE The purpose of this study was to determine the added diagnostic value of various three-dimensional (3D) data viewing techniques when analyzing contrast-enhanced 3D MR angiography. MATERIALS AND METHODS Twenty patients (mean age, 62 years) with symptomatic peripheral vascular disease were assessed with breath-hold, contrast-enhanced 3D MR(More)
BACKGROUND The benefits of percutaneous angioplasty of renal artery stenosis is not known. In an attempt to better define the patient subgroup most likely to benefit from a revascularization procedure, the relationship between renal arterial morphology, blood flow volume, and renal volume was investigated using magnetic resonance (MR) techniques. METHODS(More)
The gene for von Recklinghausen neurofibromatosis (NF1), one of the most common autosomal-dominant disorders of humans, was recently mapped to chromosome 17 by linkage analysis. The identification of two NF1 patients with balanced translocations that involved chromosome 17q11.2 suggests that the disease can arise by gross rearrangement of the NF1 locus, and(More)
BACKGROUND Epithelioid hemangioendotheliomas are rare vascular tumors, mostly originating from soft tissue, lungs or liver. CASE REPORT A 58-year-old woman was admitted to hospital because of upper congestion, Horner's syndrome and segmental sensory disturbance. MRI of the spine showed a spinal mass, reaching from the seventh cervical vertebra to the(More)
The aim of this article was to obtain initial experiences with fluoroscopically triggered contrast-enhanced (CE) 3D MR DSA with elliptical centric k-space order and 3D time-of-flight (TOF) turbo MRA of the carotid arteries. In this prospective study we examined 16 consecutive patients with suspicion of atherosclerotic disease involving the carotid arteries.(More)
PURPOSE To investigate bolus timing artifacts that impair depiction of renal arteries at contrast material-enhanced magnetic resonance (MR) angiography and to determine the effect of contrast agent infusion rates on artifact generation. MATERIALS AND METHODS Renal contrast-enhanced MR angiography was simulated for a variety of infusion schemes, assuming(More)
