Medical imaging is a critical tool in the detection, staging, and treatment planning of upper urinary tract urothelial carcinoma (UTUC). This article reviews the strengths and weaknesses of the different imaging techniques and modalities available clinically. This includes multidetector computed tomography (CT), multiparametric magnetic resonance imaging (MRI), ultrasound (US), and positron emission tomography (PET) for the detection, staging, and management of UTUC. In addition, we review the imaging techniques that are being developed and are on the horizon but have not yet made it to clinical practice. Firstly, we review the imaging findings of primary UTUC and the techniques across multiple modalities. We then discuss imaging findings of metastatic disease. Lastly, we describe the role of imaging in the surveillance after resection of primary UTUC based upon current guidelines.
医学成像是诊断、分期及治疗规划上尿路尿路上皮癌(UTUC)的关键工具。本文综述了临床现有不同成像技术与方法的优缺点,包括多排计算机断层扫描(CT)、多参数磁共振成像(MRI)、超声(US)以及正电子发射断层扫描(PET)在UTUC的检测、分期和管理中的应用。此外,我们还回顾了正在开发中、即将应用但尚未进入临床实践的成像技术。首先,我们总结了原发性UTUC的影像学表现及跨多种模态的成像技术;随后探讨了转移性疾病的影像学特征;最后,基于现行指南阐述了影像学在原发性UTUC切除术后监测中的作用。
