摘要

膀胱癌是泌尿道最常见的恶性肿瘤之一。它与显著的发病率和采用侵入性手术(如膀胱镜检查)的长期随访有关。最初的诊断和分期依赖于切除或活检样本的组织病理学分析。然而,它与严重的分期不足有关,通常需要多次重新分期。随着磁共振成像技术(即弥散加权成像)的最新进展,可以提高可疑病变的检出率及其向膀胱壁深层的延伸,从而改善分期。在随访期间也可以发现复发肿瘤,甚至预测进展率。在这项工作中,作者打算回顾目前关于磁共振成像在膀胱癌患者的检测、分期和随访中的作用的文献。

O papel da ressonância magnética em doentes com tumor vesical

Bladder cancer is one of the most common malignancies of the urinary tract. It is associated with significant morbidity and long‐term follow‐up using invasive procedures, like cystoscopy.

The initial diagnosis and staging are dependent on the histopathologic analysis of resected or biopsed samples. However, it is associated with significant under‐staging, often requiring multiple re‐staging procedures.

With the recent advances in Magnetic Resonance Imaging techniques, namely Diffusion Weighted images, it has become possible to improve the detection rate of suspicious lesions and their extension to the deep layers of the bladder wall, therefore improving staging. It is also possible to detect recurrent tumours during follow‐up and even to predict the progression rate.

With this work, the authors intend to review the current literature regarding the role of Magnetic Resonance imaging in the detection, staging and follow‐up of bladder cancer patients.
