摘要

目的:比较5.0T磁共振成像、3.0T磁共振成像和MDCT在识别胰岛素瘤和确定肿瘤与导管关系方面的能力:方法:在2021年10月至2024年2月期间,连续招募了一系列高度怀疑为胰岛素瘤的患者,他们在术前接受了5.0T磁共振成像,以及3.0T磁共振成像或MDCT。由三名观察员对 5.0T、3.0T MRI 和 MDCT 的主观和客观图像质量、病灶与胰腺对比度、主胰管(MPD)清晰度以及肿瘤与导管的关系进行评估。分析了肿瘤-导管距离与临床相关的术后胰瘘(CR-POPF)风险之间的相关性:本研究共纳入 40 名胰岛素瘤患者(14 名男性,平均年龄为 46.4 ± 16.5 岁)。其中 21 人同时接受了 5.0T 和 3.0T MRI 检查,38 人同时接受了 5.0T MRI 和 MDCT 检查。5.0T 磁共振成像的观察者内部和观察者之间的一致性良好至极佳。与 3.0T 相比,5.0T MRI 在 T1WI 和 DWI 上显示出明显更高的主观和客观图像质量(p 结论:与 3.0T MRI 和 MDCT 相比,5.0T MRI 在检测胰岛素瘤和评估肿瘤与导管关系方面具有一定优势。

Insulinoma detection and surgery planning: a comparative study of 5.0T MRI versus 3.0T MRI and MDCT.

Purpose: To compare the ability among 5.0T MRI, 3.0T MRI and MDCT in identifying insulinomas and determining the tumor-to-duct relationship.

Methods: A consecutive series of patients highly suspected of insulinomas were enrolled between October 2021 and February 2024, who underwent 5.0T MRI preoperatively, as well as 3.0T MRI or MDCT. The subjective and objective image quality, lesion-to-pancreas contrast, clarity of main pancreatic duct (MPD) and tumor-to-duct relationship at 5.0T, 3.0T MRI and MDCT were evaluated by three observers. The correlation between tumor-duct distance and clinically relevant postoperative pancreatic fistula (CR-POPF) risk was analyzed.

Results: Forty patients (14 men; mean age, 46.4 ± 16.5 years) with insulinomas were included in this study. 21 of them underwent both 5.0T and 3.0T MRI; and 38 of them underwent 5.0T MRI and MDCT. The intra- and inter-observer agreement of 5.0T MRI were good to excellent. 5.0T showed significantly higher subjective and objective image quality on T1WI and DWI compared to 3.0T (p < 0.05). Lesion-to-pancreas contrast was superior across all sequences at 5.0T compared to 3.0T(p < 0.05). A head-to-head comparison of patients who received both 5.0T and 3.0T MRI demonstrated that tumor detection was superior with 5.0T MRI (5.0T: 100%; 3.0 T: 92.0%, p < 0.05). Feasibility of tumor-to-duct relationship assessment was superior at 5.0T, compared to 3.0T and MDCT (93.2%, 64.0% and 52.3%, respectively, p < 0.05). Tumor-duct distance could predict CR-POPF after enucleation surgery (areas under the ROC curve 0.79, p = 0.01).

Conclusion: 5.0T MRI exhibits certain superiority in detecting insulinomas and assessing tumor-to-duct relationship compared to 3.0T MRI and MDCT.

期刊介绍: Abdominal Radiology seeks to meet the professional needs of the abdominal radiologist by publishing clinically pertinent original, review and practice related articles on the gastrointestinal and genitourinary tracts and abdominal interventional and radiologic procedures. Case reports are generally not accepted unless they are the first report of a new disease or condition, or part of a special solicited section. Reasons to Publish Your Article in Abdominal Radiology: · Official journal of the Society of Abdominal Radiology (SAR) · Published in Cooperation with: European Society of Gastrointestinal and Abdominal Radiology (ESGAR) European Society of Urogenital Radiology (ESUR) Asian Society of Abdominal Radiology (ASAR) · Efficient handling and Expeditious review · Author feedback is provided in a mentoring style · Global readership · Readers can earn CME credits
