Role of CTA versus CT or PET/CT in the diagnosis of pulmonary embolus – pro

Whereas CTA has been found to be more sensitive, and some claim too sensitive for routine use, than VQ scans, it has not been compared to PET/CT and it is not known how CTA should be used for patients with negative PET/CT. Farthermore, CTA often reveals other diagnosis and the usefullness of PET/CT is unclear if CTA would anyway be used. There is, therefore no medical necessity to perform both studies together.
