64- and 128-slice CT scanners from other manufacturers. After the acquisition of Revolution CT, nearly all CCTAs were done on the new system and we were able to accommodate a 212% increase in the number of CCTA studies performed each year, from an average of 721 exams/year to 1,533/year (Figure 2). Figure 1. A CT scan is an X-ray study that uses a computer to produce 3D cross-sectional images of the body. The CT scanner obtains detailed pictures of internal organs, bones and soft tissues—and differs from a medical X-ray image in that it uses a doughnut-shaped machine to emit X-ray beams at different angles.

However, the use of beta blockers to lower the heart rate to less than 65 beats per minute (bpm) is common in 64-slice CT imaging of patients with suspected CAD. The mean CT number of each material was then compared to the actual CT number range from the phantom specifications. The measured CT numbers in the study for the various targets were all within the minimum and maximum range as specified by the manufacturer except for the Delrin and bone 20% which were found to be slightly outside the range. Figure 1b shows reconstructed images from the 128-slice DSCT and 320-row ADCT scanners. The impulse signal of the respective acquisition modes (SHM and DHM) for the 128-slice DSCT appeared as one- and two-streak responses. On the other hand, the 320-row ADCT image appeared as only a one-streak response in the respective reconstructed CT image. The Diagnostic Performance of 64-Slice CT Coronary Angiography: Vessel-by-Vessel Analysis. The diagnostic performance of CT coronary angiography for detecting significant lesions on a vessel-based analysis is detailed in Table 2. One significantly diseased LAD was incorrectly classified as nonsignificantly diseased on the CT scan. Methods: The scanners investigated were a newly installed Siemens Biograph mCT PET with 64-slice SOMATOM Definition AS CT using sinogram affirmed iterative reconstruction (SAFIRE) and two GE Discovery 710 PET scanners with 128-slice Optima 660 CT using adaptive statistical reconstruction (ASiR).
