Also commonly referred to as a CT scan, Computed Tomography is an imaging technique that combines multiple X-ray images taken from different angles. This produces detailed cross-sectional internal images. The first CT scanner for medical use dates from 1972. The resulting images provide greater information than regular X-rays, allowing doctors to examine individual slices within the 3-D images. Contrast agents are commonly used in combination with CT scans to perform angiographies and other specific tissue examinations.
CT SCANS ARE OFTEN USED TO EVALUATE:
- Organs in the pelvis, chest and abdomen
- Colon health (CT colonography)
- Presence of tumours
- Pulmonary embolism (CT angiography)
- Abdominal aortic aneurysms (CT angiography)
- Spinal injuries
Technological improvements in CT such as dose modulation acquisition techniques and iterative reconstruction algorithms dramatically reduce the required X-Ray dose, improve hospital efficiency and clinical effectiveness and reduce costs.
