This document summarizes a pulmonary ventilation/perfusion scan that was performed on an 80-year-old female patient with a history of hypertension and newly diagnosed Burkett's lymphoma. The scan involved nuclear medicine tests to evaluate lung ventilation and perfusion. The findings showed a heterogeneous pattern of tracer distribution in the left lung with multiple matched defects seen on both the perfusion and ventilation scans, suggesting a pulmonary embolism. The conclusion was that the scan results were consistent with the patient's current symptoms of potential pulmonary embolism.

3. Introduction
• A pulmonary ventilation/perfusion scan involves
two nuclear scan test to evaluate
• breathing (Lung ventilation).
• circulation (Lung perfusion).
• They may be done separately or together.

5. Case History
• 80 years old female patient known case of Hypertenstion (HTN.)
• Newly diagnose case of Burketts lymphoma having high pulmonary artery pressure on echocardiogram
• (ECHO.)
• Indication for perfusion:
• Evaluation of
• pulmonary embolism (PE), the main cause being deep vein thromboses (DVTs),clots from recent surgery, or trauma.
• pulmonary perfusion.
• chest pain or shortness of breath (SOB).
• Indication for ventilation in conjunction with lung perfusion;
• Evaluation of
• pulmonary embolism (PE).
• chronic obstructive pulmonary disease (COPD)

6. Preparation
• A recent (24 hour) chest radiograph.
• Rehearse the breathing procedure to assure optimal patient cooperation; instruct the patient to breathe
by mouth.
• To assist in distribution to lungs, patient should be asked to cough and take in several deep breaths
before injection

7. Technique
• View: ANT, POST, LATERAL, 4 OBLIQUES.
• Radiopharmaceutical:
• Ventilation: Tc99m Aerosol (400 MBq).
• Perfusion: Tc99m MAA (100 MBq).

8. Case History

9. Finding
A significantly heterogeneous pattern of tracer distribution is noted in left lung both in perfusion and
ventilation with evidence of multiple non-segmental matched defects and no evidence of segmental
or mismatched.
A matched defects noted in Lt upper lobe.

10. Conclusion
• VQ scan have many advantages;
• This scan is readily available, with minimal risks involved.
• It’s a relatively good test for blood clots in his-her lungs and current symptoms suggest that you might have a
pulmonary embolism
