V/Q scan sample dictation
HISTORY: The patient is  year-old  with . Evaluate for pulmonary embolism.
PROCEDURE: Initially, ventilation images of both lung fields were obtained following the inhalation of aerosolized Tc-99m DTPA. Then, perfusion images of both lung fields were obtained following the IV administration of  mCi Tc-99m MAA.
COMPARISION: [ ]
A chest radiograph dated  is available for evaluation.
FINDINGS: The pulmonary ventilation/perfusion scan demonstrates a [large/small/nonsegmental] perfusion defect in the  segment of the  lobe, [mismatched/matched] on ventilation images.
Evaluation of the remaining images demonstrates no definite mismatched perfusion defects.
Ventilation is worse than perfusion.
IMPRESSION: Radionuclide pulmonary ventilation/perfusion scintigraphy.
1.  probability for pulmonary embolism.
[2. Recommend repeat baseline VQ scan after treatment of current embolism.]
