While only approximately 2% to 5% of these patients have renovascular hypertension, this still represents a significant number of patients with a potentially treatable disease. There is a definite need for a cost-effective, noninvasive screening examination. The advent of innovative magnetic resonance imaging (MRI) technology has led the way for single breath-hold 3D contrast-enhanced magnetic resonance angiography (MRA) to potentially replace conventional angiography in many clinical instances. This technique is safe, accurate, noninvasive, and has the advantage of avoiding nephrotoxic iodinated contrast in the many patients with renal insufficiency and suspected renovascular hypertension.Wednesday, 16 Jan 2002 23:42:45 GMT
