CT scanning of the whole body with spiral and sequential techniques is performed on the Somatom Plus 4 Spiral CT Scanner. The Spiral scanning techniques employed for the chest and abdomen enables an entire volume or region of the body to be scanned in one or two breath-holds, thus eliminating motion and misregistration artefacts. Tiny nodules in the lungs and liver can be detected with greater accuracy.
Dual/Triple phase contrast enhanced scans are also performed with the spiral scanning techniques, to evaluate and characterize tumours in the liver, pancreas, kidneys etc. by scanning during the arterial and venous phases following contrast injection. Newer applications like CT Angiography, 3-D reformatted images and Bone Mineral Densitometry can also be performed on the spiral CT Scanner.
