Abstract:
PURPOSE: To compare breath-hold gadolinium enhanced MR angiography(MRA) with digital subtraction angiography. MATERIALS AND METHODS: Ten patients underwent angiography and breath-hold gadolinium enhanced MRA;the latterperformed at 1.5T with 3D FSPGR after a bolus injection of gadopentetate dimeglumine(0.4mmol/kg) RESULTS: Sevenof ten pathologic conditions(70%) evaluated by both techniques had a similar appearance. The conditions examinedwere as follows : the artery feeding renal cell carcinoma(n=2): renal artery stenosis(n=2); pulmonaryAVM(n=2);abdominal aortic aneurysm(n=1); atheromatous plaque in the lower abdominal aorta(n=1);an enlargedbronchial artery(n=1); and an aberrant renal artery(n=1). For evaluating an anatomic relationship, a reconstructed3D image obtained by MRA is more advantageous. CONCLUSION: Breath hold contrast enhanced MRA is a potentiallyuseful noninvasive screening method for detecting vascular abnormality of the aorta and its branches.
