Specifically, lesions in non-targeted regions were detected more often for patients suspected of CCAD than for those suspected of CAD (71.4% vs 61.7%). With 21.5% (~51.1 s) reduction of scan time and 21.8% (~20.8 mL) less contrast medium as compared to the consecutive protocol, high-...
Utilizing more controlled training datasets or introducing intermediate scan homogenization techniques may further assist the framework learning process, however, caution must be exercised in use of chained-AI algorithms to avoid error propagation and diminishing returns. Conclusion Handcrafted and DL CT-...
A heart CT scan generally would be covered by health insurance only if prescribed by a doctor for a patient at risk for coronary artery disease or who has symptoms such as chest pain; but some insurers do not cover the test under any circumstances. Examples include Medicare, which covers hea...
Cox proportional hazards regression (with time to first event) was used to estimate hazard ratios (HRs) comparing (1) events by intention-to-treat in CCTA vs control (non-CCTA) patients; and (2) events in patients who actually received the screening CT scan vs those who did not (as-...
