RADIONUCLIDE PERFUSION AND XENON-133 VENTILATION (V/Q) LUNG SCAN

DATE: 10/03/05

PROCEDURE:  Xenon-133 ventilation and washout images were obtained in the posterior projection after inhalation of Xenon-133 gas in the airway. Following IV administration of 99mTc-macroaggregates of albumin, perfusion images of the lung were obtained in the anterior, posterior, and bilateral oblique projections.  

XENON-133 DOSE: [10] mCi

Tc-MAA DOSE: [5] mCi

CORRELATIVE STUDIES: None.

COMPARISON: None.

CLINICAL HISTORY: The patient is a [...]-year-old [fe]male with a history of [...]. The patient is referred to rule out pulmonary embolism.

FINDINGS: 

Ventilation study: Uniform distribution of Xenon gas is observed in both lung fields during equilibrium phase with normal wash out period.

Perfusion study: There is diffuse homogeneous uptake visualized on the perfusion images.  No segmental defects are seen.

CONCLUSIONS:

Under PIOPED criteria, this study is consistent with normal V/Q lung scan.

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