We analyzed the effectiveness of using 64-slice spiral computed tomography (CT) and perfusion imaging to guide argon-helium cryoablation treatment of liver cancer. In total, 60 cases of advanced hepatocellular carcinoma before surgery treated with argon-helium cryoablation were inlcuded in the present study. Retrospective summary of the 60 cases of metaphase and advanced liver cancer were used ...

With the introduction of spiral/helical multislice CT, medical x-ray CT began a transition into cone-beam geometry. The higher speed, thinner slice, and wider coverage with multislice/cone-beam CT indicate a great potential for dynamic volumetric imaging, with cardiac CT studies being the primary example. Existing ECG-gated cardiac CT algorithms have achieved encouraging results, but they do no...

INTRODUCTION To compare the accuracy of graded compression ultrasonography (US) and unenhanced spiral computed tomography (CT) in the diagnosis of acute appendicitis. METHODS This prospective study comprised 58 consecutive patients with high clinical suspicion of acute appendicitis. After careful clinical assessment and laboratory investigations, all the patients were independently evaluated ...

BACKGROUND AND PURPOSE The goal of this study was to determine the efficacy of CT angiography for the characterization of plaque morphology and composition in carotid atherosclerotic disease. METHODS Fifty-five patients undergoing carotid endarterectomy were imaged preoperatively with single-slice spiral CT angiography. One hundred sixty-five endarterectomy sections were examined histological...

introduction: computed tomography (ct) is an imaging technique with gives us an opportunity to review cross sections of the body in live animals. in veterinary medicine although ct is mostly used for diagnostic purposes in small animals, but in recent years ct also has been used as a non invasive modality in non clinical studies. jebeer gazelle (gazella bennettii) is one of the species of the g...

X-ray-computed tomography (CT) successfully underwent a transition from slice-by-slice imaging to volume imaging in the decade after 1990 due to the introduction of spiral scan modes. Later, the transition from single-slice to multislice scanning followed. With the advent of new detector technologies we are now looking forward to circular and spiral scanning using area detectors and the respect...
