摘要
背景:磁共振肠溶解(MRE)已被广泛应用于克罗恩病(CD)的诊断。3.0 T 的磁共振(MR)提高了信噪比(SNR),缩短了图像采集时间,显示出更多优势:方法:选取 2021 年 1 月至 2022 年 12 月在我院住院的 48 例 CD 患者作为研究对象。这 48 名 CD 患者均接受了双气囊肠镜和 3.0 T MRE 检查。研究人员观察了 MRE 的动脉相位信号、静脉相位信号、肠壁和肠腔,以确定患者是否患有活动性 CD。根据肠镜检查结果,筛选出 MRE 诊断的真阳性、真阴性、假阴性和假阳性人数,并计算出 MRE 评估活动性 CD 的诊断准确性、敏感性和特异性:结果:48 例患者中,39 例经 MRE 诊断为小肠 CD,与肠镜检查结果无明显差异(P>0.05)。根据 MRE 诊断结果,动脉期主要呈高信号强度,静脉期主要呈低信号强度或等密度。小肠 CD 病变主要表现为肠壁增厚、罕见的肠壁气肿强化、肠腔气肿或扩张以及罕见的狭窄。此外,MRE 诊断 CD 的准确性为 93.75%,敏感性为 97.37%,特异性为 80.00%。
Diagnostic Value of 3.0 T Magnetic Resonance Imaging in Active Crohn's Disease.
Background: Magnetic resonance enteroclysis (MRE) has been widely applied to diagnose Crohn's disease (CD). Magnetic resonance (MR) at 3.0 T improves signal-to-noise ratio (SNR), shortens image acquisition time, and shows more advantages.
Objective: This study aimed to retrospectively analyze the diagnostic value of 3.0 T MR imaging for active CD.
Methods: 48 CD patients hospitalized in our hospital from January 2021 to December 2022 were selected as the study subjects. These 48 CD patients underwent both double-balloon enteroscopy and 3.0 T MRE. All patients' arterial phase signal, venous phase signal, bowel wall, and bowel lumen of MRE were observed to identify whether they suffered from active CD. Based on the results of enteroscopy, the number of true positives, true negatives, false negatives, and false positives diagnosed by MRE were screened; next, the diagnostic accuracy, sensitivity, and specificity of MRE in assessing active CD were calculated.
Results: Of the 48 patients, 39 were diagnosed with small bowel CD by MRE, which was not significantly different from the results of enteroscopy (P>0.05). According to MRE diagnostic results, the arterial phase predominantly presented high signal intensity, and the venous phase mainly presented low signal intensity or isointensity. Small bowel CD lesions were primarily characterized by bowel wall thickening, rare pneumatosis enhancement of the bowel wall, bowel lumen pneumatosis or dilatation, and rare strictures. Besides, MRE presented an accuracy of 93.75%, sensitivity of 97.37%, and specificity of 80.00% in diagnosing CD.
Conclusion: 3.0 T MR imaging has diagnostic value for active CD and shows certain clinical application value.
