Results: Our patients were divided into a lower CAC score cases (CAC score, =300, n=12 cases/12 lesions) and a higher CAC case (CAC score, >300, n=48 cases/66 lesions). The highest vessel CAC score mean is of LAD 100.1卤 61.98 followed by RCA then...

Results were calculated by 3 CACS algorithms, namely, the Agatston score, the volumetric score, and the mass score of the four major coronary arteries, including the LM, LAD, LCX, and RCA, as obtained by syngo.via: 04.02.0000.0009 (Siemens Healthcare, Germany). The total CACS was defined...

(CNN) which takes a CT volume as input and processes it slice-by-slice. The CNN performs two operations end-to-end: First, it segments calcium lesions that contribute to the Agatston score. Second, the CNN categorizes each calcium lesion as belonging to the LCA, LAD, LCX, or RCA. We...
For that purpose, CTA is less effective in patients with calcium score greater than or equal to 600 and in patients with a high pre-test probability for obstructive CAD. (CTA is most useful as a rule-out test in patients with low-intermediate pre-test probability of disease and mild ...
