Whatis the difference between 64 slice and 128 slice CT Scanner? The 128-slices CT scanners have more rows of detectors, which means that these systems provide larger volume coverage and shorter examination times. This is very useful in cardiac studies. 16 64, 128 and 256 Slice CT Scanners - Assessing the Costs vs. Benefits. Cost and Benefits of Various CT Scanner Slice Options. CT scanners can be of great benefit to most healthcare providers due to their ability to capture high-resolution diagnostic images at a fast rate ( the scanner's speed makes it a especially beneficial in the ER). Wepresent an evaluation of a recently introduced 64-slice CT (64SCT) system, which makes use of a periodic motion of the focal spot in the longitudinal direction (z-flying focal spot) to double the number of simultaneously acquired slices.

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

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. Prospectivelygated 64‐slice CT coronary angiography (CTCA) may be contraindicated for heart rates (HRs) over 65 beats per minute (bpm) due to reduced diagnostic sensitivity. Newer CT scanners typically provide 128 or more slices and superior temporal resolution compared with older models; consequently, diagnostic accuracy for current Increasedspeed, detector size and sensitivity mean doctors can scan a heart, lung or brain with considerably less radiation than a scan with a 64-slice CT or a nuclear stress test. The 64-slice scanners required four to six heart beats to capture an image of the entire heart. The 256 can cover the distance in two heartbeats. Whilesome experts have argued that a 16-slice system is sufficient from a practical standpoint, a closer examination of 32- and 64-slice systems offers new and superior clinical benefits over and above 16-slice technology, especially in imaging of the coronary arteries and in multiphase and functional studies.
