DYNAMIC RADIONUCLIDE RENAL IMAGING WITH LASIX 

DATE: 5/1/2006

PROCEDURE: After bolus IV injection of radiopharmaceutical, dynamic posterior projection images of the kidneys were acquired over a total of 26 minutes at: 1 sec/frame x 60 frames, 5 sec/frame x 24 frames, and 30 sec/frames x 54 frames. After IV injection of Lasix, additional 60 sec/frames x 20 frames were obtained. 

RADIOPHARMACEUTICAL: Tc 99m MAG3 

RADIOPHARMACEUTICAL DOSE: [10] mCi 

CAPTOPRIL DOSE: [25] mg

COMPARISON: None 

CLINICAL HISTORY: The patient is a [...]-year-old [fe]male with a history of [...]. The patient is referred for evaluation of renal artery stenosis. 

FINDINGS: 

The blood perfusion images show prompt tracer in both renal fossae, consistent with normal renal perfusion. 

Extraction, excretion and clearance appear normal for the both kidneys. 

The differential renal function is [...]% (left) and [...]% (right). 

CONCLUSIONS: 

1. Normal renal function bilaterally with Captopril challenge. Low probability for rennin dependent renovascular hypertension.

2. The differential renal function is [...]% (left) and [...]% (right). 

Thank you for referring this patient to the UCLA Nuclear Medicine Clinic. 

I, [...], M.D., Ph.D., have reviewed this Nuclear Medicine study personally, and am in full agreement with the findings of the report presented here.
