AZOTEMIA - GADOPENTETATE DIMEGLUMINE AS CONTRAST AGENT AT DIGITAL SUBTRACTION ANGIOGRAPHY

In an azotemic patient with suspected renal artery stenosis, undiluted gadopentetate dimeglumine was administered in an aortic bolus to prov ide contrast at digital subtraction angiography of the aorta and renal arteries. The contrast material (5 mmol/mL) was power injected (rate, 15 mL/sec; total dose, 30 mi). Selective renal arteriography was also performed with 5 mi of undiluted gadopentetate dimeglumine hand injec ted into each renal artery (total dose, 40 mt). The patient tolerated the procedure without complication or worsening of renal function, and diagnostic angiographic images were obtained.
