Comparison of aspirin renogram and captopril renogram in the diagnosis of renovascular hypertension

Renal artery stenosis (RAS) is the most common cause of secondary hypertension. Preliminary data indicate that aspirin renography with hippurate may be more sensitive for detection RAS. In this study 20 patients with known or suspected RAS underwent aspirin renography (20 mg/kg orally 1 hour before injection of radiotracer) and captopril renography (50 mg orally) with 99mTc-DTPA. Renal an...

Promotion of radioisotope excretion.

Nuclear medicine would be greatly aided if compounds were available to promote the excretion of unwanted radioisotopes from biological systems. Such preparations would make possible greater use of long-lived radionuclides in medicine and would reduce some of the environmental hazards associated with nuclear energy. The biochemistry of radioisotope excretion is complicated because there are so m...

Interpretation of the renogram: problems and pitfalls in hydronephrosis in children.

OBJECTIVE To discuss the main steps of renographic technique and underline some pitfalls related to the acquisition, processing and interpretation of diuretic renography, an important method for guiding the management of asymptomatic congenital hydronephrosis. METHODS Despite guidelines and consensus protocols, renographic procedures differ among centres, causing difficulties in comparison an...
