Accurate preoperative diagnosis of renal vein, vena caval, or intracardiac extension of Wilms' tumor allows the surgeon to better plan operative vascular control and assess the potential benefits of preoperative chemotherapy. Magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound were used to study four consecutive patients presenting with Wilms' tumor. Three had vena caval involvement, with one of these having a massive right atrial tumor thrombus. A fourth patient had renal vein involvement only. We found MRI to be superior to both CT and ultrasound for mapping intravascular extension of Wilms' tumor and for delineating nonvascular disease. Because of its noninvasiveness, multiplane imaging capabilities, and image contrast and resolution, MRI is a valuable complimentary imaging modality for the diagnosis and follow-up of patients with Wilms' tumor.
准确术前诊断肾静脉、腔静脉或心脏内延伸的威尔姆斯瘤，可使外科医生更好地规划手术中的血管控制，并评估术前化疗的潜在益处。使用磁共振成像（MRI）、计算机断层扫描（CT）和超声对连续4例患有威尔姆斯瘤的患者进行研究。其中3例有腔静脉受累，其中1例有巨大的右心房肿瘤血栓。第4例患者仅肾静脉受累。我们发现，在描绘威尔姆斯瘤的血管内延伸和勾勒非血管性病变方面，MRI优于CT和超声。由于其无创性、多平面成像能力以及图像对比度和分辨率，MRI是威尔姆斯瘤患者诊断和随访中有价值的辅助成像方式。
