“…With EBCT scanning, typically 3-mm thick slices are acquired contiguously with prospective ECG triggering in mid-diastole and an exposure time of 100 ms per slice. An effective radiation exposure of approximately 0.9 mSv was reported for this protocol [2].…”

“…Recently, alternative quantitative volumetric scoring methods have been developed that have improved interscan reproducibility [11]. Partial-volume errors introduced by contiguous acquisition with 3-mm slice width, long breathhold times of 25-40 s, and image artifacts due to inconsistent ECG triggering for arrhythmic heart rates have been identified as the main variability factors [2].…”

Reproducibility of coronary calcium quantification in repeat examinations with retrospectively ECG-gated multisection spiral CT

High reproducibility is a key requirement for coronary calcium scoring in follow-up examinations. We investigated the interexamination reproducibility of calcium scoring with retrospectively ECG-gated multisection spiral CT (MSCT). Fifty patients were examined twice with MSCT. Slices were reconstructed with retrospective ECG gating in the diastolic phase with 3-mm slice width and up to 125-ms temporal resolution. We calculated the Agatston score, calcium volume with and without isotropic interpolation, and calcium mass, and derived the mean and median variability. We investigated the change of variability with use of 3-mm nonoverlapping and overlapping increments (2, 1.5, 1 mm). Use of overlapping increment results in considerably reduced interscan variability. We observed a minimum mean variability of 12% and a minimum median variability of 9% for the Agatston score. For volume and mass quantification we obtained a minimum mean variability of 7.5% and a minimum median variability of 5%. Multisection spiral CT enables coronary calcium quantification with high reproducibility in follow-up examinations mainly founded on image data with reduced partial-volume errors due to overlapping increment.

“…The accuracy of CCT for CAC scoring is confirmed. [18,19] The examined circulating factors were measured monthly and averaged to obtain a mean value for each factor. The mean essential calcium intake per month administered as calcium carbonate during the study period was taken into account as well.…”

“…Coronary artery calcification score was evaluated every six months for a total period of 30 months in all 40 patients with CCT (Tomoscan Philips 5000) using a nonspiral 240° partial sequence scan mode, as described by Becker et al [18,19] Forty slices of 3 mm thickness were acquired from 1 cm below the tracheal bifurcation to the base of the heart. Images were acquired at the end of inspiration.…”
