【摘要】：目的：探討胃腸道間質(zhì)瘤的CT表現(xiàn)及與病理分級(jí)的關(guān)系,為臨床治療提供依據(jù)。 方法：收集本院2009年9月至2012年12月經(jīng)手術(shù)病理證實(shí)的GIST患者37例,全部病例行多層螺旋CT平掃及雙期增強(qiáng)掃描。分析全部病例的CT圖像,包括強(qiáng)化方式、密度、部位、大小、形態(tài)及有無浸潤(rùn)等,并與病理危險(xiǎn)度分級(jí)結(jié)果進(jìn)行比較分析。 結(jié)果：37例GIST中胃占51.35%,小腸占27.03%,直腸2例,腹膜后2例,腹腔和盆腔3例,多發(fā)性1例。黏膜下型占18.92%,漿膜下型占37.84%,肌壁間型占29.73%,胃腸道外型占13.51%。CT表現(xiàn)腫瘤大小為2.0-22cm,5.Ocm占72.97%(高度16例,中度10例,低度1例),≤5.Ocm占27.03%(低度8例；極低度2例)。腫瘤形態(tài)規(guī)則,圓形或卵圓形,邊界清楚占43.24%(高度2例,中度4例,低度8例,極低度2例)；腫瘤形態(tài)不規(guī)則,以分葉為主,與鄰近分界不清者占56.76%(高度14例,中度6例,低度1例)。腫塊密度不均勻占67.57%(高度16例,中度7例,低度2例)；均勻占32.43%(中度3例,低度7例,極低度2例)；不均勻強(qiáng)化占62.16%(高度16例,中度6例,低度1例),均勻強(qiáng)化占37.84%(中度4例,低度8例,極低度2例)。 結(jié)論：GIST的CT表現(xiàn)具有一定的特點(diǎn),腫瘤的大小、形態(tài)、密度及強(qiáng)化方式對(duì)于評(píng)估GIST的危險(xiǎn)度分級(jí)有參考價(jià)值,CT可以在術(shù)前對(duì)GIST的危險(xiǎn)度作出初步的評(píng)價(jià)。
[Abstract]:Objective: to investigate the CT features of gastrointestinal stromal tumors (GIST) and their relationship with pathological grading. Methods: from September 2009 to 2012, 37 patients with GIST confirmed by operation and pathology were collected. All cases were performed multi-slice spiral CT plain scan and dual-phase enhanced scan. The CT images of all cases were analyzed, including enhancement mode, density, location, size, morphology and infiltration. The results were compared with pathological risk classification. Results among the 37 cases of GIST, 51.35 were in stomach, 27.03 in small intestine, 2 in rectum, 2 in retroperitoneal, 3 in abdominal and pelvic cavity, 1 in multiple, and 18.92% in submucosal type. The subserous type was 37.84%, the muscular wall type was 29.73 and the gastrointestinal tract external type was 13.51 cm. Ct showed that the tumor size was 2.0-22 cm. (5) Ocm accounted for 72.97% (high 16 cases, moderate 10 cases, low degree 1 case), 鈮，
