WebbThe introduction of new array detector technology for multislice CT improves CT-scan capabilities. Compared to single-slice helical CT, this technique offers three significant advantages: the pitch can be increased by a factor of 4, resulting in shorter acquisition times and contrast media saving, the temporal and spatial resolution are improved and … WebbAnother advantage of spiral CT is that it delivers a lower dose of radiation than traditional CT scans. Spiral CTs also can be used to look for masses in the adrenal glands, brain and other organs that may be affected if lung cancer has spread. A disadvantage of spiral CT scans is that they are expensive.
