RADIONUCLIDE LIVER LUNG SHUNT EVALUATION

DATE: 4/20/2006
 
TECHNIQUE: Via a catheter placed in the hepatic artery, Tc-99 MAA was injected. Subsequently gamma camera images from both anterior and posterior directions were obtained over the liver and bilateral lungs to calculate the hepatopulmonary shunt fraction. 

RADIOPHARMACEUTICAL DOSE:  [4] mCi Tc-99 MAA

CLINICAL HISTORY: The patient is a [...]-year-old [fe]male with a history of [...]. The patient is referred for evaluation of live to lung shunt fraction for SIRSPHERE therapy.  

CORRELATIVE STUDIES: None.

COMPARISON: None.

FINDINGS: 

Planar images demonstrate focal areas of increased uptake in the [...]. 

The liver to lung shunt fraction is [...]%.
