See below: Prob not a pulmonary embolism but certainly good thing to rule out. I prefer ct pulmonary angiogram to vent perfusion but it should be adequate.

Odds don't count: Stastitics are only guidelines and don't apply to individual cases. A lung scan (v/q) is accurate if it is considered high probability or normal. The " gold standard" is computerized angiogram of the chest which is very accurate both to diagnose or exclude pulmonary embolism. Talk to your md. If you have no medical contraindications, i would prefer the ct angiogram.
