QUANTITATIVE LUNG PERFUSION EVALUATION

DATE: 10/4/2005

PROCEDURE:  Following IV administration of 99 mTc macroaggregates of albumin (MAA), images of the lungs were acquired.  Calculations of relative lung perfusion were based on the geometric mean activity [sqrt (anterior x posterior)] of each lung in the anterior and posterior projections.

99mTc MAA DOSE: [1.5] mCi

CORRELATIVE STUDIES: None.

COMPARISON: None.

CLINICAL HISTORY: The patient is a [...]-year-old [fe]male with [...]. The patient is referred for evaluation of any flow defects.

FINDINGS:  

LUNG FIELD        LEFT        RIGHT
UPPER             [...]%      [...]%
MID               [...]%      [...]%
LOWER             [...]%      [...]%
TOTAL             [...]%      [...]%

CONCLUSIONS: Patchy tracer activity is noted throughout both lungs, but there is a relatively even distribution of tracer between the left and right lungs. The left lung receives approximately [...]% of the total lung perfusion, while the right receives [...]%.

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.
