The reference method for characterising a solid renal mass is computed tomography. MRI and ultrasound can provide useful diagnostic information for characterising masses the cystic or solid nature of which it is not possible to determine from data from the CT scan. For characterising a solid mass, only MRI can replace the CT scan in most cases. Once a mass has been shown to be solid and vascularised and not occurring in a context suggesting an inflammatory pseudotumour, it can be put, using CT, into one of the four categories of the classification that we propose: pseudotumoral dysmorphisms (type 1); typical high-fat angiomyolipomas (type 2); suspect indeterminate tumours (type 3); typically malignant tumours (type 4).
用于描述实体性肾肿块的参考方法是计算机断层扫描。磁共振成像和超声可以为肿块的特征提供有用的诊断信息，对于那些从 CT 扫描数据无法确定其囊性或实性的肿块尤其如此。在大多数情况下，MRI 可用于替代 CT 扫描来描述实性肿块。一旦确定肿块为实性且富血管性，且其发生的部位不提示炎症性假瘤，则可以使用 CT 将其归入我们提出的分类的四个类别之一：假瘤性畸形（1 型）；典型的富含脂肪的血管平滑肌脂肪瘤（2 型）；疑似不确定的肿瘤（3 型）；典型的恶性肿瘤（4 型）。
