METHODS: This retrospective study analyzed a cohort of 55 hysterectomy patients, utilizing pre-operative pelvic MRI and post-operative CT scans to measure the LASV. To evaluate the consistency between MRI and CT, the study employed the intraclass correlation coefficient and Bland-Altman agreement analysis in a subset of 32 patients with both pre-operative scans. A paired-samplet test was used to analyze LASV changes pre- and post-hysterectomy, and linear regression analysis was performed to account for potential risk factors that may influence post-operative LASV.
RESULTS: High consistency between MRI and CT in measuring LASV was found, with an ICC of 0.911. We observed a significant increase in LASV following hysterectomy, with mean volume pre- and post-operatively of 16.66 cm3 and 18.87 cm3 respectively. Age and body mass index were significant predictors of post-hysterectomy LASV, whereas parity and the type of hysterectomy had no significant impact.
CONCLUSIONS: Hysterectomy significantly affects the LAM, resulting in an increase in post-operative LASV. Moreover, this study verifies that MRI and CT can be used interchangeably for LASV measurements in clinical practice.
方法:这项回顾性研究分析了55名子宫切除术患者的队列,利用术前盆腔MRI和术后CT扫描测量LASV。评价MRI与CT的一致性,本研究采用了全组相关系数和Bland-Altman一致性分析,对32例患者进行了两种术前扫描.使用配对样本测试来分析子宫切除术前后的LASV变化,并进行线性回归分析,以解释可能影响术后LASV的潜在危险因素.
结果:发现MRI和CT测量LASV的一致性很高,ICC为0.911。我们观察到子宫切除术后LASV显著增加,术前和术后的平均体积分别为16.66cm3和18.87cm3。年龄和体重指数是子宫切除术后LASV的重要预测因素,而产次和子宫切除术的类型没有显著影响.
结论:子宫切除术显著影响LAM,导致术后LASV增加。此外,本研究验证了MRI和CT在临床实践中可交替用于LASV测量.
