The value of high-resolution real-time ultrasonography in locating parathyroid adenomas was compared with that of computed tomography (CT). In 21 patients with a single parathyroid adenoma verified at neck exploration, preoperative ultrasonography and CT detected the adenoma in 15 and 11 cases, respectively. Ultrasound gave false-positive results in four patients and false-negative in two, whereas CT was false-positive in four patients and false-negative in six. Most false-positive reports were due to misinterpretation of small thyroid nodules. For acceptable accuracy both methods require an experienced radiologist. Technical and interpretive problems seem to be somewhat less frequent with ultrasonography than with CT. Ultrasonography has therefore become the method of choice for preoperative location of enlarged parathyroid glands at our hospital, and CT is used as a complementary procedure, e.g. when a mediastinal adenoma is suspected.
将高分辨率实时超声检查法在定位甲状旁腺腺瘤方面的价值与计算机断层扫描（CT）进行了比较。在21例经颈部探查证实为单一甲状旁腺腺瘤的患者中，术前超声检查和CT分别在15例和11例中检测到腺瘤。超声检查有4例假阳性结果和2例假阴性结果，而CT有4例假阳性结果和6例假阴性结果。大多数假阳性报告是由于对小甲状腺结节的错误解读。为了达到可接受的准确性，两种方法都需要经验丰富的放射科医生。与CT相比，超声检查在技术和解读方面的问题似乎略少。因此，超声检查已成为我院术前定位增大甲状旁腺的首选方法，而CT则用作补充检查，例如当怀疑有纵隔腺瘤时。
