The authors evaluated magnetic resonance angiography (MRA) as a possible diagnostic method to image the left renal vein. Twenty-five patients with abdominal aortic aneurysm underwent both plain and contrast-enhanced CT, as well as two-dimensional (2D) sequential time of flight (TOF) MRA. MRA images were evaluated on the basis of the results of CT, taken as the "gold standard" for vessel demonstration. MRA was performed with a 1.5 T superconductive magnet (Magnetom), fast imaging with steady-state free precession (FISP) 2D sequence (TR 40 ms, TE 10 ms, FA 18 degrees). Images were acquired in breath-hold on the coronal and sagittal plane and reconstructed according to maximum intensity projection (MIP) and targeted-MIP techniques. MRA images acquired on the sagittal plane correctly showed the retroaortic course on the left renal v. in six cases. On the coronal plane, targeted-MIP reconstructions for the course of the left renal v. correctly detected its outlet at the level of the inferior vena cava in five cases and of the left iliac v. in one case. MRA appears to be a promising noninvasive vascular imaging technique capable of correctly detecting the course and the outlet of the left renal v. We particularly noticed that the lef...Continue Reading

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
