直肠癌的发病率呈逐年上升趋势,故术前正确诊断直肠癌及直肠癌的分期至关重要,目前大部分磁共振(MR)检查多只使用常规序列扫描。本研究制定了一组高分辨磁共振成像(HR-MRI)的检查方法,对60例直肠癌患者进行术前检查,并与手术病理作对照研究,旨在进一步提高MRI对直肠癌分期的诊断率。
The incidence of rectal cancer is increasing year by year, so the correct diagnosis of rectal cancer and staging before surgery is crucial, most of the current magnetic resonance (MR) examination using only conventional sequence scanning. This study developed a set of high-resolution magnetic resonance imaging (HR-MRI) examination method for 60 cases of rectal cancer patients preoperative examination and surgical pathology for controlled study to further improve the MRI diagnosis of staging of rectal cancer rate.
