Usefulness of Isotropic Volumetric Data in Neuroradiological Diagnosis
It is generally recognized that the major advantages of multislice CT are a longer scanning range and shorter scanning times due to the incorporation of multiple rows of detectors. Due to these characteristics, multislice CT is particularly useful for the evaluation of the thoracoabdominal region, where the organs are relatively large and in which scanning should be performed during a single breath-hold. However, multislice CT is as useful in neuroradiological diagnosis as it is in thoracoabdominal studies. The high scan speed of multislice helical CT permits helical scanning to be performed with a smaller slice thickness than is possible in conventional helical CT. As a result, volumetric data with superior resolution in the z axis can be obtained. This is also useful for the visualization of the structures of the central nervous system in fine three-dimensional detail.
