LUNG

 

lung (normal #1) image#1 image#2

Clinical Indications: 48 year old white female w/ chest pain - V/Q scan.

Dose: 3mCi Tc-99m DTPA aerosol, 6 mCi Tc-99m MAA given i.v.

Results: normal ventilation scan and near normal perfusion lung scan with very low probability of acute pulmonary embolism; showed small defects in the left mid-lung field without peripheral segment perfusion defects - probably represent unresolved, old pulmonary embolism.

Clinical Indications: patient has history of breast carcinoma with right mastectomy; ventilation/perfusion lung scintigraphy.

Dose: 3mCi Tc-99m-DTPA via inhalation, 5mCi Tc-99m-MAA given i.v.

Results: poor ventilation to both lungs - shallow breathing; defects within the left lower lobe with some perfusion noted to the periphery of the lung consistent with a "stripe sign"; findings are consistent with categorization into a low probability for pulmonary embolism.


lung (abnormal #2) image#1 image#2

Clinical Indications: 47 year old white female with acute onset of shortness of breath, wheezing, and tachycardia; patient has history of breast cancer with a right mastectomy and is currently on chemotherapy; study to rule out pulmonary embolism.

Dose: 4.5 mCi Tc-99m MAA given i.v., 1mCi Tc-99m DTPA given i.v.

Results: volume loss in right kidney; defect in right lung in lateral segment of right middle lobe w/ no match to ventilation study; intermediate probability for pulmonary embolus.

 


lung (abnormal #3) image#1 image#2

Clinical Indication: 53 year old white male with multiple myeloma - ventilation/perfusion scan.

Dose: 3mCi Tc-99m DTPA via inhalation, 5 mCi Tc-99m MAA given i.v.

Results: no areas of defects in ventilation or perfusion scans; low probability of pulmonary embolism.
