Treatment selection of renal masses is informed largely by size. Furthermore, decisions regarding active surveillance involve closely monitoring growth kinetics. It is, therefore, important to understand the accuracy behind radiographic size as compared with pathologic.
A large number of studies indicate computed tomography (CT) imaging overestimates pathologic size, albeit by a small amount. Smaller masses tend to be overestimated, but larger masses underestimated. Clear cell renal cell carcinoma masses are more likely to be overestimated. CT, ultrasound and MRI have similar concordance with pathologic size.
The differences between radiographic and pathologic size are small. Findings show good efficacy across CT, MRI and ultrasound. This may reduce reliance on CT imaging alone in the future.
肾肿块的治疗选择在很大程度上取决于其大小。此外，关于主动监测的决策涉及密切监测生长动力学。因此，了解影像学大小与病理学大小之间的准确性非常重要。
大量研究表明，与病理相比，计算机断层扫描（CT）成像高估了病变大小，尽管幅度很小。较小的肿块往往被高估，但较大的肿块被低估。透明细胞肾细胞癌肿块更有可能被高估。CT、超声和 MRI 与病理大小具有相似的一致性。
影像学大小与病理大小之间的差异很小。研究结果表明 CT、MRI 和超声的效果都很好。这可能会减少未来对 CT 成像的依赖。
