8 slices per second scanner a large length of the body can be
quickly scanned in a single short breath hold. Image resolution
is much better as compared to conventional spiral CT Scanner.
Reconstructed images have same resolution as the axial images,
which help to better define the pathology from different
projections. Various softwares are available to add in the
Now two and three phase contrast CT study can be done to depict
arterial, venous and late phase to detect and characterized the
lesion of liver (metastasis, hepatic cellular carcinoma) and
pancreas. CT portogram can be obtained without any difficulty to
see the patency or collateral flow. Retroperitoneal pathology
can be better defined. CT colonography can be performed in the
difficult cases when colonoscopy is not possible. ECG gated
images of the heart can be obtained to analyze the morphology of
the heart. Calcium scoring of the coronary arteries can be done
to predict the risk of future heart attack.
Three dimensional (3-D) angiography of the major blood vessels
(aorta, carotid, cerebral, renal and major peripheral arteries)
can be obtained using pressure injector to infuse the contrast
and bolus chasing technique to start the scan at optimal time.
This non-invasive technique obviates the necessity of
conventional angiography in may situations.
3-D reconstructions of spine and bony structure can be obtained
to better delineate the pathology and morphology and for
High resolution scan of the small osseous structures (like
wrist), inner ear and temporal bone is very satisfying in terms
of both image quality and ease of scanning.
In chest CT, except routine chest studies, patients can be
scanned to rule out pulmonary embolism. High resolution CT of
the chest to define interstitial pathology need very thin
sections and appropriate exposure factor, which is not a problem
in this canner. Due to availability of “Lung care” software even
a small lung nodule not appreciable in visual evaluation can be
detected. Due to optimal timing of scanning following contrast
injection by pressure injector differentiation of mediastinal
vascular structure and nodal/mediastinal pathology becomes every
easy. Fly through technique help to navigate through bronchial
lumen to visualize major bronchial pathology.
