  • The CT Diagnosis of Thymic Carcinoid and the Literature Review

    目的:总结胸腺类癌的临床表现、病理特征、CT表现及其临床价值。方法:对本院收治的2例胸腺类癌进行分析并结合文献复习。结果:胸腺类癌发病率低,大部分早期患者无临床症状,经胸部X线、CT检查时发现;中晚期始出现症状。病理检查出类癌后,电镜可见神经内分泌颗粒,免疫组化显示神经特异性烯醇化酶、肿瘤嗜铬蛋白A、促皮质素阳性。胸部CT表现特征为起于前上纵隔肿块,常位于心底部大血管和心包周围,肿块内密度不均,可见钙化,增强后轻中度强化,易发生胸内外转移。结论:胸腺类癌是一罕见的前纵隔肿瘤,根据CT特征,结合临床可有助诊断、指导手术、推测预后,因此CT在临床诊治中有非常重要的价值。

  • Analysis of the Radiological Performance of Pelvic Fracture in Wenchuan Earthquake

    目的:分析汶川大地震中伤员骨盆骨折的发生部位及骨折类型。方法:对地震发生后近2个月内先后送至四川大学华西医院治疗的95例骨盆骨折伤员,按放射学检查结果进行骨折部位及类型分析。结果:95例伤员共发生133个部位的骨折。按骨折部位分类:髂骨22个(16.6%),坐骨10个(7.5%),耻骨81个(60.9%),髋臼18个(13.5%),骶尾骨2个(1.5%)。按骨折类型分类:斜行骨折71个(53.4%),粉碎性骨折43个(32.3%),线性骨折11个(8.3%),横行骨折5个(3.7%),嵌插骨折3个(2.3%)。结论:地震造成骨盆骨折部位以耻骨为主,类型以斜行骨折为主。对骨盆骨折伤员,X线及CT检查相结合能为临床提供更好的影像诊断价值。

  • The Imaging Manifestations of Ankylosing Spondylitis Involving the Spine on Low-field MRI

    目的 采用低场MRI非增强扫描探讨强直性脊柱炎(AS)累及脊柱的MRI表现。 方法 从2010年3月-2013年3月间就诊的76例AS患者的MRI图像中选取19例脊柱受累者资料,对病变部位MRI图像进行分析,评价AS累及脊柱在低场MRI非增强扫描状态下的MRI表现特点。 结果 19例患者中颈椎病变3例,胸椎病变9例,腰椎病变7例;MRI表现为椎体终板炎17例、椎间盘炎13例、脊柱滑膜关节炎15例、椎旁韧带炎11例、韧带骨化和骨性强直9例。 结论 低场MRI非增强扫描能直观显示AS脊柱病变,主要表现为椎体终板炎、椎间盘炎、脊柱滑膜关节炎、椎旁韧带炎、韧带骨化和骨性强直,压脂T2WI序列对活动性炎性病变显示良好,T1WI、T2WI序列能较好显示结构性病变。

  • Diagnosis of Gastrointestinal Invasion by Carcinoma of Gallbladder on Spiral CT(Report of 8 Cases )

    【Abstract】ObjectiveTo study the spiral CT features of gastrointestinal invasion by carcinoma of gallbladder. MethodsEight patients with surgical-pathologically documented gastrointestinal invasion by carcinoma of gallbladder were analyzed retrospectively. All patients underwent plain and contrast-enhanced dual-phase scanning of the abdomen. Oral contrast medium (1.2% Angiografin) was used to fill the gastrointestinal tract before CT scanning. ResultsThere were 2 cases of gastric antrum invasion, 6 duodenal invasion and 3 colonic invasion according to the surgical and pathological findings. Spiral CT correctly diagnosed 2 gastric invasion and 4 duodenal invasion based on several imaging features, like blurring of fat plane, focal wall thickening and luminal narrowing of involved gastrointestinal segments, and mass formation. However CT was unable to diagnose the 3 cases of hepatic flexure of colon invasion. ConclusionCT is valuable for diagnosing upper gastrointestinal tract invasion by carcinoma of gallbladder, yet the diagnosis of hepatic flexure of colon invasion is still difficult.
