DYNAMIC RADIONUCLIDE RENAL IMAGING

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. 

RADIOPHARMACEUTICAL: Tc 99m MAG3 

RADIOPHARMACEUTICAL DOSE: [10] mCi 

COMPARISON: None 

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

FINDINGS: 

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

The extraction appears [normal/mildly decreased] and excretion is severely compromised for both kidneys. There is persistent tracer activity in the renal cortices.

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

CONCLUSIONS: 

1. Normal renal perfusion with persistent tracer activity in the renal cortex and no excretion is consistent with an ATN-like pattern.

2. The differential renal function is [...]% (left) and [...]% (right) (a difference of up to 45/55% is considered normal). 

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.
