Abstract

Objectives: Our study aims to demonstrate the detection of invasion by biparametric prostate MRI (bpMRI).

Materials and methods: The cases whose histopathological diagnosis was prostate cancer (PCa) and whose mpMRI report was reported as PIRADS 4 and 5 were evaluated retrospectively by two radiologists with different prostate imaging experiences. The images were grouped into two data sets. Dataset-1 was bpMRI, and dataset-2 was mpMRI. Two radiologists first evaluated dataset-1 independently of each other, and 1 month later, dataset-2. They recorded whether there was an invasion and where it was seen in the patients. Then, the results were compared.

Results: A total of 75 patients were included in the study. Periprostatic invasion was detected in 33 of the patients. Both the 1st reader and the 2nd reader image detected all the cases with invasion (100%) separately between dataset-1 and set-2. Compatibility for image dataset-1 and dataset-2 between both readers was observed to be excellent.

Conclusions: There is no need to use contrast agent to evaluate periprostatic invasion and to have an idea about local staging in PCa patients.

造影剂在前列腺癌前列腺周围浸润评价中的作用。

目的：我们的研究旨在证明双参数前列腺MRI（bpMRI）对侵袭的检测。材料和方法：由两名具有不同前列腺成像经验的放射科医生对组织病理学诊断为前列腺癌症（PCa）且mpMRI报告为PIRADS 4和5的病例进行回顾性评估。这些图像被分为两个数据集。数据集1为bpMRI，数据集2为mpMRI。两名放射科医生首先对数据集1进行了独立评估，1个月后对数据集2进行了评估。他们记录了是否有入侵，以及在患者身上的位置。然后，对结果进行比较。结果：本研究共纳入75例患者。33例患者发现前列腺周围侵犯。第一个读取器和第二个读取器图像分别在数据集1和数据集2之间检测到所有入侵病例（100%）。观察到两个读取器之间的图像数据集-1和数据集-2的兼容性非常好。结论：无需使用造影剂来评估前列腺癌患者的前列腺周围侵犯情况，也无需了解前列腺癌的局部分期。
