ACE Inhibitor Renogram Test and Its Price in India

ACE Inhibitor Renogram is a renal scan that evaluates the presence of renal artery stenosis and renovascular hypertension. In individuals with high blood pressure, this is done to rule out renal artery stenosis. It is also known as Captopril Renal Scan.

Why is ACE Inhibitor Renogram Done?

Doctors recommend this scan for the patient with high blood pressure problems, to evaluate the presence of renal artery stenosis and renovascular hypertension.

What is the procedure for ACE Inhibitor Renogram?

ACE-inhibition renogram is performed using oral captopril or intravenous enalaprilat (Vasotec) as the ACE inhibitor. A normal renogram that becomes abnormal in the left or right kidney after ACE inhibition is highly specific for renovascular hypertension. There are two possible diagnostic strategies, and the choice will rely on localized circumstances.

• Basic renogram followed by an ACE inhibitor (oral captopril or intravenous enalaprilat) and a repeat renogram. This option provides the most definitive information but it requires two renograms and requires the patient to spend 2– 3hr in the nuclear medicine department.
• The patient is given an ACE inhibitor, then has a renogram after skipping the baseline renogram. If the ACE-inhibition renogram is normal, the study is a low probability for renovascular hypertension, and there is no need for the baseline renogram. To maximise specificity, the patient must have the baseline examination again the following day if it is abnormal; otherwise, high-risk individuals with an abnormal study may be referred for angiography.

If the study is normal, this option offers the same diagnostic details as option 1 above, however it is less detailed if the study is abnormal; However, only one renogram is necessary, and the patient just needs to be in the department for 1-2 hours.

Procedure

You will receive either Captopril or Enaloprilate intravenously prior to or during the renal scan with the ACE Inhibitor. You will lie down under a gamma camera after the captopril has been given, and for the next hour, your blood pressure and pulse will be checked every 15 minutes. A little quantity of radiotracer will be injected intravenously.

Depending on their health and blood flow, the kidneys will receive the radiotracer. You will be imaged with the camera under the table for about 30 minutes during the captopril renal scan. Rarely would you need to return later to pick up the about five to ten minute-delayed images.

Preparation for ACE Inhibitor Renogram

For all Ace-Inhibitor Renogram, you must be well-hydrated before the exam. You need to drink at least one liter of fluid per hour before your appointment. It's also crucial to avoid eating for at least four hours prior to the test, though. Some medications need to be stopped before the exam. A doctor will instruct you about the medications.
