128Slice and higher. These 128-slice or higher CT scanners are the top-of-the-line CT scanners you will find. Up to 320 slices, these machines can provide a full-body scan in mere seconds. Thanks to its incredible speed and accuracy, specialty practices generally invest in these costly machines.
Comparedwith 16-slice and 64-slice CT, 128-slice CT has more detectors, which means larger volume coverage and shorter scan times. These advantages are useful for the application in CCTA. Compared with the other scanner systems 7,8,13, 128-slice single-source CT (128-MSCT) can use a low-tube current with acceptable images 14,15. First
Whatis the difference between 64-slice and 128 slice CT? To reduce the radiation dose, it is important to use different methods with the scanner provided. Compared with 16-slice and 64-slice CT, 128-slice CT has more detectors, which means larger volume coverage and shorter scan times.
Comparedwith 16-slice and 64-slice CT, 128-slice CT has more detectors, which means larger volume coverage and shorter scan times. These advantages are useful for the application in CCTA.
Latest128-slice dual-source CT (DSCT) scanners offer prospective high-pitch spiral acquisition covering the heart during one single beat. We compared radiation dose and image quality from prospective 64-MSCT versus high-pitch spiral 128-slice DSCT scanning, as such data is lacking.
Forthe 4-slice example, this corresponds to a pitch of 3/4 = 0.75; for a 16-slice scanner, the pitch is 15/16 = 0.9375; and for a 64-slice scanner, the pitch is 63/64 = 0.9844. Note that such pitches move closer to 1 (smaller fraction of beam overlap) as the number of simultaneously acquired slices increases (more information regarding this
