目的 :探讨常规MRI联合弥散加权成像诊断结肠癌性肠梗阻的临床价值。方法 :选取在我院收治且经手术病理证实的60例结肠癌患者,对其进行无肠道准备的MRI多序列多方位扫描和弥散加权成像检查,观察分析MRI及弥散加权成像特点。结果 :60例结肠癌患者中有38例患有结肠癌性肠梗阻,定位符合率为100%,38例结肠癌性肠梗阻患者表现为近肠管扩张,腹腔积液,结肠积粪,肠腔狭窄、增厚,呈线样或肩样征象,肠壁表现为T1W1低信号和DWI明显高信号。结论 :常规MRI联合弥散加权成像诊断结肠癌性肠梗阻准确可靠,具有较高的诊断价值,值得推广应用。
Objective: To investigate the clinical value of conventional MRI combined with diffusion-weighted imaging in the diagnosis of colon cancer ileus. Methods: Sixty patients with colon cancer who were confirmed by surgery and pathology in our hospital were enrolled in this study. MRI multi-sequence MRI and diffusion-weighted imaging were performed without intestine preparation. The features of MRI and diffusion-weighted imaging were analyzed. Results: Among 60 patients with colon cancer, 38 patients had colon cancer with intestinal obstruction. The coincidence rate was 100%. The patients with colon cancer with intestinal obstruction included proximal dilatation, hydronephrosis, colon intestine, Stenosis, thickening, was linear or shoulder-like signs of intestinal wall showed low signal of T1W1 and DWI significantly high signal. Conclusion: Conventional MRI combined with diffusion-weighted imaging in the diagnosis of colon cancer ileus is accurate and reliable, which has high diagnostic value and is worth popularizing.
