Computed Tomography : State of the Art and Future Applications

초록

The indication for combined spiral computed tomography (CT) during hepatic arteriography (CTHA) and CT during arterial portography (CTAP) was mainly to detect nodular lesions, which are associated with liver cirrhosis on pre-existing imagings, such as conventional CT scans (non-contrast CT, contrast enhanced CT or hepatic arterial phase of IV bolus spiral CT), MR, ultrasonography (US) and US-guided percutaneous biopsy, etc. Most of the patients at high risk of hepatocellular carcinoma (HCC) had at least one or two nodules suspected on previous images. Our interests were to evaluate how many more nodules were detected on combined CTHA and CTAP or either one or the other and which would be better to depict the entire nodules in the liver.
