Twenty-two patients with primary hyperparathyroidism underwent high-resolution magnetic resonance (MR) imaging with local (surface) coils for preoperative localization of enlarged parathyroid glands. The MR studies were interpreted prospectively and the results compared with findings at surgery and the results of computed tomography (CT), ultrasonography (US), and thallium-technetium scintigraphy (TTS). The sensitivity and specificity of MR imaging were .74 and .88, respectively. The sensitivity/specificity for the other modalities were as follows: 74/.95 for CT, .59/.82 for US, and .82/.98 for TTS. Enlarged parathyroid glands displayed a medium-intensity signal on T1-weighted images and a marked increase in intensity on T2-weighted images, but the degree of increase varied considerably.
22例原发性甲状旁腺功能亢进患者接受了使用局部（表面）线圈的高分辨率磁共振（MR）成像检查，以对增大的甲状旁腺进行术前定位。对MR研究进行前瞻性解读，并将结果与手术发现以及计算机断层扫描（CT）、超声检查（US）和铊-锝闪烁扫描（TTS）的结果进行比较。MR成像的敏感性和特异性分别为0.74和0.88。其他检查方式的敏感性/特异性如下：CT为74/0.95，US为0.59/0.82，TTS为0.82/0.98。增大的甲状旁腺在T1加权图像上显示中等强度信号，在T2加权图像上强度显著增加，但增加程度差异很大。
