概括

计算机断层扫描 (CT) 能够有效地区分异型胰腺 (HP) 和小胃肠道 stromal 瘤 (GIST). 关键的CT特征,如边界,小直径和损伤减弱,有助于区分这些疾病,提高诊断准确度.

科学领域:

放射学放射学是一门学科.
胃肠病学胃肠病学
在瘤学瘤学.

背景情况:

异型胰腺 (HP) 和小胃肠层瘤 (GIST) 的准确手术前诊断非常重要,因为它们的治疗方法和预后不同.
在手术前区分HP和小GIST可以防止不必要的侵入性手术.

研究的目的:

为了研究HP的计算机断层扫描 (CT) 功能.
为了确定区分HP和小GIST之间的CT特征.

主要方法:

从2016年1月到2020年8月,对HP和GIST病例的CT扫描和组织病理学结果进行了回顾性分析.
使用费舍尔精确测试,曼 - 惠特尼U测试,ROC曲线和反向概率权重进行统计分析,以确定显著的差异变量.

主要成果:

包括轮,边缘,增强等级,表面,管状结构,短直径 (SD),未增强的损伤减弱 (Lp) 和增强比率 (ER) 在内的CT特征对差异化具有重要意义.
区分HP和小GIST的独立因素包括定义不好的边界,表面,管状结构,Lp,SD和ER.
SD和Lp的值分别为1.40厘米和42.33霍恩斯菲尔德单位.

结论:

CT参数如轮,相对增强度,SD和Lp有效地区分HP和小GIST.
管状结构和表面小穴的存在可以进一步表征HP.
这些发现可以帮助避免不必要的侵入性检查和治疗无症状HP.

Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
