The 64-row ct is usually sufficient for colon and abdominal examinations. Of course, the conditions allow 256 rows of ct is also not bad. They also have price differences.

64-row spiral CT using a new generation of high-power high-milliamp output bulb, the detector rows up to 64 rows, helical scanning speed faster (≤ 0.35 seconds / turn), the temporal resolution is significantly improved (<50 milliseconds), cardiac sub-millimeter thickness of CT scanning time is only about 5 to 9 seconds, can obtain excellent coronary artery CT images.
The 256-layer high-speed CT is also known as 256-layer high-speed CT because of its lower X-ray dose, faster rotation speed, and higher degree of intelligence, and its maximum time resolution of 34 milliseconds, general cardiac examination can be done in only 2 heartbeats, because the X-ray dose is 60% ~ 80% lower than previous CT equipment, known as green imaging equipment, and because it can be completed under cardiac gating. The CTA examination of the torso and other large-scale, solid can be widely used for health checkups, compound injuries, chest pain triad ...... whole body wide range of rapid, low X-ray dose examination and diagnosis.
