Does A Normal Lung Perfusion Scan With A Normal Xray
Yes, it's the first choice of examination in suspected patients
Detailed Answer:
Hello and welcome to 'Ask A Doctor' service.
I can understand your concern,
Yes, a lung perfusion scan is the examination of choice in patients suspected of pulmonary embolism. If you don't have signs and symptoms such as acute breathlessness, chest pain or less commonly cough then, in my opinion, the probability of having PE is low even if you have DVT. However, you should wear elastic stocks, try to move the extremities frequently.
On the contrary, if you have the above signs and symptoms you should absolutely do an Angio CT scan of the chest to exclude pulmonary embolism. Please discuss this with your doctor.
Hope to have been helpful

Hi again
In such patients with contrast allergy we do a premedication with steroids IV one day before the chest CT in close consultation with alergologist specialist . As you explain the situation and according to the perfusion scan it doesn't seem to me you have PE. However in my opinion you should take LMWH regardless side effects . Nevertheless it's your treating doctor to decide exactly which is the best option for you.
