Thank you, I thought that was the case. But whenever I say "CTPA" my coresidents look at me weird or try to correct me.I've never heard or used "CTPE", but I'm sure it's just shorthand for a pulmonary embolism protocol chest CT, which is exactly what a CTPA is. CTPA was our term for such a study in residency, and I still use it all the time, but no one else at my current hospital does. On the other hand, I always just say PE or pulmonary embolism, while every else I work with says PTE or pulmonary thromboembolism.
Just whatever you do, don't ask for a "spiral" CT to look for emoblism.
A CT angiogram involves CT with intravenous contrast. The differences between CTA chest (for aorta), CTPA (for pulmonary arteries), and routine CT chest with contrast are protocol details such as amount of contrast, speed of contrast administration, timing of imaging acquisition (eg, triggered by peak enhancement in the region of interest), the direction of acquisition (apex to base or base to apex), the tradeoff between speed and detail (eg, slice thickness, pitch, rotation speed), and image reconstruction algorithms (eg, thin cuts, maximal intensity projection, 3D)So an angiogram is basically a CT w/ contrast?
