Physicians who ordered more CT pulmonary angiogram scans experienced a markedly decreased proportion of positive results, according to new research published in JAMA Internal Medicine.“Pulmonary ...

Meanwhile, dose calculations showed that the limited CT pulmonary angiography scan reduced overall patient radiation exposure by 34.4%, from 11.1 to 7.25 mSv, and significantly reduced radiation ...

The latency period for potential cancer induction is estimated to be 10-30 years in the dose ranges used in CT pulmonary angiography. Thus, the younger the patient is at the time of exposure, ...

Catheter pulmonary angiography remains the gold standard for diagnosis;1 however, access to this procedure is often limited, it is invasive, and interobserver agreement is suboptimal for subsegmental ...

Background: Incidental finding of pulmonary nodules on CT is frequent and application of cancer screening derived follow up (f/u) algorithms could produce multiple repeated scans with low yield, high ...

Batra et al.’s AJR accepted manuscript included patients who underwent CT pulmonary angiography (CTPA) before (October 1, 2018–March 31, 2019) and after (October 1, 2019–March 31, 2020 ...

Ultimately, the commercial AI tool had NPV of 99.8% and PPV of 86.7% for detection of iPE on conventional contrast-enhanced chest CT examinations (i.e., not using CT pulmonary angiography protocols).
