摘要

目的:本研究旨在测量直肠癌患者直肠肿瘤最低边界到肛门边缘的精确距离(DTAV)。材料与方法:对70例直肠癌患者的临床资料进行回顾性分析。DTAV测量通过经直肠双翼超声、MRI和结肠镜收集。结果:超声测量的DTAV平均值(US平均值)与结肠镜检查的DTAV值相差0.22 cm。相比之下,US平均值与MRI的差值为0.48 cm, MRI与结肠镜的差值为-0.26 cm。DTAV测量的ICC显示出极好的一致性,US平均值和MRI之间的值为0.948,US平均值和结肠镜之间的值为0.942,MRI和结肠镜之间的值为0.943。超声获得的最小DTAV值(US min)为5.05 cm,超声获得的中间DTAV值(US mid)为5.10 cm,超声获得的最大DTAV值(US max)为5.30 cm。值得注意的是,DTAV测量值在US max和US min、US max和US mid以及US mid和US min之间的差异中位数分别为0.2 cm、0.1 cm和0.1 cm。此外,DTAV测量值US min与US mid、US max与US mid、US min与US max的一致性极好,ICC值均达到0.999。此外,放射科医生对MRI DTAV数据的重新评估显示与原始结果非常一致,ICC值为0.985。结论:利用EFOV成像技术经直肠双平面超声测量DTAV具有较高的准确性和重复性。该方法为DTAV测量提供了一种高效实用的临床工具。

Evaluating Extended Field of View Imaging for Measuring Rectal Tumor Lowest Boundary to Anal Verge Distance via Transrectal Biplane Ultrasound.

Purpose: This study aimed to measure the precise distance from the lowest boundary of a rectal tumor to the anal verge (DTAV) in patients with rectal cancer.

Materials and methods: A retrospective analysis was performed on clinical data from 70 rectal cancer patients. DTAV measurements were collected using transrectal biplane ultrasound, MRI, and colonoscopy.

Results: The difference in DTAV measurements between the mean DTAV value obtained by ultrasound (US mean ) and colonoscopy exhibited a difference of 0.22 cm. In contrast, the difference between US mean and MRI was 0.48 cm, while the difference between MRI and colonoscopy was -0.26 cm. The ICC for DTAV measurements demonstrated excellent agreement, with values of 0.948 between US mean and MRI, 0.942 between US mean and colonoscopy, and 0.943 between MRI and colonoscopy. The minimum DTAV value obtained by ultrasound (US min ) was 5.05 cm, the middle DTAV value obtained by ultrasound (US mid ) was 5.10 cm, and the maximum DTAV value obtained by ultrasound (US max ) was 5.30 cm. Notably, the median values of the differences in DTAV measurements between US max and US min , US max and US mid , as well as US mid and US min , were 0.2 cm, 0.1 cm, and 0.1 cm, respectively. Furthermore, the consistency of DTAV measurements between US min and US mid , US max and US mid , as well as US min and US max was excellent, with all ICC values reaching 0.999. Additionally, the radiologist's reassessment of MRI DTAV data showed excellent consistency with the original results, with an ICC value of 0.985.

Conclusion: Transrectal biplane ultrasound utilizing EFOV imaging technology exhibited both accuracy and reproducibility for measuring DTAV. This approach provided a highly efficient and practical clinical tool for DTAV measurement.
