The histologic type of adrenal tumors can be accurately predicted by MRI on the basis of their signal intensity on a T2-weighted image. However, a small but significant number of nonfunctioning adenomas, carcinomas, and metastases cannot be differentiated because they have similar signal intensities on a spin-echo 2500/80 scan. Eight (21%) of 38 of these tumors fell into this group. Differentiation between incidental adenomas and metastases can be conclusively achieved only when the primary neoplasm can also be imaged and displays high signal intensity on T2-weighted images.
肾上腺肿瘤的组织学类型可通过磁共振成像（MRI）根据其在T2加权图像上的信号强度准确预测。然而，一小部分但数量可观的无功能腺瘤、癌和转移瘤无法区分，因为它们在自旋回波2500/80扫描中具有相似的信号强度。这些肿瘤中的38个中有8个（21%）属于这一组。只有当原发肿瘤也能成像并在T2加权图像上显示高信号强度时，才能最终实现偶然发现的腺瘤与转移瘤之间的区分。
