Due to the complex blood supply of the liver (30% from Hepatic artery and 70% from Portal vein) a triphasic spiral CT
technique is developed to image the entire liver in arterial, portal, and delayed phases6.
A dual-phase contrast-enhanced spiral CT
was performed immediately after the procedure to assess the immediate response after ablation and to screen for related complications.
scanning was conducted using a 64-row scanner (Siemens, Germany) (collimation = 64 x 1, slice thickness = 1 mm, pitch = 1:1, current = 120 kV with automatic mA adjustment, thin layers with three-dimensional image reconstruction).
CT axial plain scan and enhancement scan were performed on all the cases using SOMATOM sensation 16 spiral CT
machine (SIEMENS Inc.

acquisition protocol", Radiology, vol.
1,8) It offers high-end applications for surgery through real time 3D imaging, high frame rates of 30 frames per second(f/ s), and excellent image quality at low radiation exposure, which is 60-80 % less as compared to Spiral CT
has made it possible to cover body regions so rapidly that the transient enhancement of vascular system following intravenous contract injection could be captured during one scan.
CT scans were done at 64 slice spiral CT
scanner with IV contrast and slice thickness of 3mm.
10) spiral CT
of the involved tooth was conducted in the present case.
Evaluation of the spiral CT
scan revealed abnormal gas in the gallbladder fossa (figure 1 a), gas in the biliary tree, and distended loops of small bowel consistent with partial small bowel obstruction.
