常规甲状旁腺计算机断层扫描检出51%（29/57）的肿瘤，平均大小为1.5 × 1.0 × 0.8 cm。46%（7/43）的扫描由于肩纹伪影而无法解释。使用一个专门设计的病人定位装置和一个新的成像协议，包括动态扫描和静脉注射的对比剂，14例患者进行了扫描，78%（18/23）的肿瘤平均1.4 × 1.0 × 0.8厘米的大小被检测到。所有14次扫描均可判读，图像质量明显改善。
Conventional parathyroid computed-tomographic scanning detected 51% (29/57) of tumors averaging 1.5 X 1.0 X 0.8 cm in size at surgery. Forty-six per cent (7/43) of the scans were uninterpretable due to shoulder-streak artifacts. Using a specially designed patient positioning device and a new imaging protocol involving dynamic scanning and the intravenous administration of a bolus of contrast material, 14 patients were scanned; 78% (18/23) of tumors averaging 1.4 X 1.0 X 0.8 cm in size were detected. All 14 scans were interpretable, and image quality was markedly improved.
