Correct Answer » C Explanation

Ans:C. DTPA Scan.

DTPA / MAG 3 Scan

Clinical Indications:

• Assessment of GFR

• Differential renal function

• Acute renal failure

• Chronic renal failure

• Acute & chronic rejection

• Screening of patients with suspected renal hypertension

• Obstruction

• Hydronephrosis

The exam itself involves an injection of either DTPA or MAG3 followed by immediate images of the kidneys as the injection enters the body. In doing this, we are able to provide information on the renal blood flow, GFR, tubular function and urinary excretion.
