What is Helical or Spiral CT?
Helical or spiral CT is a technological improvement on regular CT, which over the recent past is gaining more popularity. Unlike regular CT, helical CT scanners are equipped with multiple image detectors and are able to image the desired area while continuously rotating around the patient. This allows faster imaging of the patient, which further adds to the comfort and convenience of the exam. It also provides the radiologist additional imaging features which further enhance diagnostic capabilities.
