The computer then processes this information and displays the corresponding images on a computer screen. The CT exam is similar to examining individual slices of bread or slices of an orange. Studies that previously took two days, such as chest and abdomen images, can now be performed in one day. One key element of this speed can be found in its helical scanning capability. This speed provides two direct benefits.
Patients enjoy shorter exam times.
Physicians get even better diagnostic information because the faster scanning speed minimizes patient motion, which can obscure small details. Helical CT has improved lesion detection and cancer staging. For example, the physician can view and film images from earlier parts of the exam while the system is still scanning the patient. At the same time, the physician can call up images from a previous exam, view them and film them as well.
