Abstract

To prospectively determine feasibility and diagnostic accuracy of 3D contrast-enhanced MR-angiography (CE-MRA) at 3.0 tesla (T) in patients with peripheral arterial occlusive disease. Digital subtraction angiography (DSA) was used as reference standard. Thirty consecutive patients with suspected peripheral arterial occlusive disease were examined on a 3.0 T MR system by using the integrated whole body coil. A 4-station examination protocol in hybrid technique was chosen, containing 2 gadodiamide injections, the first one for imaging the calf and foot arteries (single-step technique) and the second injection for the visualization of the aortoiliacal and femoral arteries (bolus-chase MRA). All patients underwent DSA within the following 48 hours. The arterial tree of each leg was divided in 15 segments and 4 anatomic regions (iliacal, femoral, popliteal/proximal calf, distal calf/foot). Two radiologists analyzed the MR-images with regard to image quality, grade of stenosis, and venous overlap. DSA-images were analyzed by 2 radiologists in consensus with regard to the stenosis grade. Eight hundred eighty-five and 884 of 889 arterial segments at CE-MRA were rated with excellent or good diagnostic image quality by observer 1 and obs...Continue Reading

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
