RESUMO
Objective To evaluate 16-SCT in diagnosing aeute appendicitis.Methods The CT findings of 34 cases were retrospectively analyzed.These cases were all proved acute appendicitis by surgical-pathology.Results 30 cases were confirmed by CT,with accuracy 88% (30/34).The diameter of 28 appendix was more than 6mm;2 collapsed with thickening wall.Periappendiceal fat stranding could be seen in 25 cases.Perforated appendicitis happened in 4 cases.Abscess performed in 2 cases.3 cases were missed,1 misdiagnosed.Conclusion 16-SCT could confirm acute appendicitis and its complication timely and accurately.
RESUMO
Objective To evaluate the value of 16-slice spiral computed tomography(SCT)in diagnosing acute aortic syndrome.Methods Thirty-four cases with acute aortic syndrome underwent 16-slice SCT,performed with unenhanced,contrast-enhanced scanning of bolus tracking and three-dimensional reconstruction.The CT findings of these cases were analysed.Results Twenty-three of them were confirmed Aortic Dessection(AD),the true and false lumen,intimal flap,extent involved and complications of which were all revealed.Six cases were confirmed intramural aortic hematoma(IMH),with features of ring or crescent-shaped non-enhanced thickening wall around the aorta.Five cases were confirmed penetrating atherosclerotic ulcer(PAU),with features of niche sign outstanding the lumen of the aorta.Conclusion Acute aortic syndrome can he diagnosed exactly and completely by 16-slice SCT,which can provide valuable information to select therapeutic methods.
