| 摘 要： | 本文对５０例正常肾上腺，４２例共４９个肾上腺病灶的ＭＲ影像进行分析，结果表明：（１）正常肾上腺信号均匀，显示率与ＣＴ相似；（２）ＭＲ可清晰显示大于１．０ｃｍ的病灶及其与周围结构的关系；（３）ＭＲ对腺瘤与转移瘤的鉴别有较大的帮助，Ｔ＿２ＷＩ腺瘤类似于肝脏的信号强度，转移瘤与脂肪的信号强度相似；（４）嗜铬细胞瘤的ＭＲ影像有特异性，Ｔ＿２ＷＩ呈明显高信号，４５％见散在点状短Ｔ＿２低信号区。

| Abstract: | In this article, the authors investigated the MR appearances of the adrenal gland in 50 nor-mal individuals and 42 patients with 49 adrenal lesions. The results showed that(1) the normal adrenal glandswere homogeneous in signal intensity and the visibility on MR was similar to that of CT.(2)All lesions largerthan 1.0cm in diameter and their relations with surrounding structures could be demonstrated clearly by MR.(3) MR could be helpful in differentiating adenoma from metastases.The signal intensity of adenoma similarto that of liver whereas metastases had high signals close to that of fat on T_2WI.(4) Pheochromocytoma wascharacterized by very high signal intensity and 45%of lesions had hypointense areas on T_2WI. |
