【摘要】：目的:通过对照磁共振PDWI抑脂序列与增强T1WI抑脂序列对肛瘘内口诊断价值的差异,探索其对手术方案选择的影响,以提高肛瘘的治疗效果。方法:68例经手术病理证实为肛瘘的患者,术前行MRI扫描。以手术结果为标准,比较分析横断位PDWI抑脂序列与增强T1WI抑脂序列对肛瘘内口的显示。结果:以手术结果为标准,PDWI抑脂序列与增强T1WI抑脂序列肛瘘内口定位诊断正确率分别为94.11%和95.58%,差别无统计学意义(P0.05)。但增强T1WI抑脂序列对肛瘘内口显示清晰度的评分明显高于PDWI抑脂序列,差别有统计学意义(P0.001)。结论:PDWI抑脂序列可以准确定位肛瘘内口,对肛瘘的术式的选择及提高治疗效果具有重要价值,但其对肛瘘内口显示的清晰度不如增强T1WI抑脂序列,不过后者需要注射MR对比剂,增加了患者经济负担和副作用风险。
[Abstract]:Objective: to explore the effect of contrast magnetic resonance (PDWI) lipid-suppression sequence and enhanced T1WI sequence on the diagnosis of anal fistula in order to improve the therapeutic effect of anal fistula. Methods 68 cases of anal fistula confirmed by operation and pathology were examined by MRI before operation. According to the results of operation, we compared and analyzed the display of transected PDWI and enhanced T1WI on the internal orifice of anal fistula. Results: the diagnostic accuracy of anal fistula was 94.11% on PDWI and 95.58% on enhanced T1WI. The difference was not statistically significant (P 0.05). But enhanced T1WI fat suppression sequence was significantly higher than that of PDWI in evaluating the articulation of anal fistula (P 0.001). Conclusion the weight PDWI sequence can accurately locate the internal orifice of anal fistula, which is of great value to the choice of operation method and improve the therapeutic effect of anal fistula. However, the clarity of the internal mouth of anal fistula is not as clear as that of enhanced T1WI sequence, but the latter needs to be injected with Mr contrast agent. Increased patient financial burden and side effects risk.
