A quantitative analysis of signal relationships using T1, proton and T2 weighted spin echo sequences was carried out using 20 parathyroid adenomas demonstrated by MRI. T1 weighted sequences from 15 adenomas were also examined following intravenous injection of Gd-DTPA. No typical signal relationship could be defined. In 4 cases the administration of contrast medium markedly increased the contrast between the adenoma and the thyroid gland. In 12 cases the tumour could be examined histologically following removal. In 2 cases there was oedema of the tumour and corresponding increased intensity of the T2 weighted sequences; in none of the other cases was there any clear correlation between the signals and the histology.
利用20例经MRI证实的甲状旁腺腺瘤，采用T1、质子和T2加权自旋回波序列对信号关系进行了定量分析。对15例腺瘤在静脉注射钆喷酸葡胺后也进行了T1加权序列检查。未发现典型的信号关系。4例中造影剂的使用显著增加了腺瘤与甲状腺之间的对比度。12例肿瘤切除后可进行组织学检查。2例肿瘤出现水肿，T2加权序列相应信号增强；其他病例中信号与组织学均无明显相关性。
