Aim of the investigation: Functional testing and imaging of the kidneys

Indications:

• Determination of the position, size and function
• In the case of suspected kidney abnormalities, e.g. double kidneys
• Clarification of urinary drainage disorders
• Inflammatory kidney processes
• Functional testing before and after chemotherapy
• High blood pressure in case of suspected renal artery stenosis

Preparation for the examination: 30 minutes before the examination, approx. 10ml/kg body weight of fluid should be drunk

Procedure of the examination:

• Doctor's consultation to explain any uncertainties regarding the examination
• Injection of the radiopharmaceutical
• Preparation of the images
• 2 blood samples during the scans and, if necessary, administration of Lasix (diuretic)
• Debriefing
• Assignment of findings to the requesting doctor as soon as possible in written form

Special features:

• if renal artery stenosis is suspected, ACE inhibitors must be discontinued 3 days before the examination
• if renal artery stenosis is suspected, the examination can be repeated after administration of captopril (antihypertensive drug)

Radiopharmaceutical used: Tc-99m MAG3
