    摘要:

    目的:分析SPECT/CT同机断层融合显像对继发性甲状旁腺功能亢进症(SHPT)甲状旁腺腺体定位诊断的应用价值。方法:35例SHPT患者常规行99mTc-甲氧基异丁基异腈(99mTc-MIBI)-双时相平面显像(MIBI平面),共出现46处甲状腺床外的异常放射性摄取灶,对颈部及床外异常摄取灶行SPECT/CT同机断层融合显像,根据手术病理结果比较MIBI平面-SPECT/CT对甲状腺床位置甲状旁腺(常位甲状旁腺)与异位甲状旁腺在敏感性及假阳性方面的差别。结果:MIBI平面及SPECT/CT对常位甲状旁腺敏感性相似(63.9% vs 67.0%,P > 0.05),SPECT/CT的假阳性百分比低于MIBI平面 (3.0% vs 18.4%,P < 0.05),MIBI平面及SPECT/CT对异位甲状旁腺敏感性均为92.5%,SPECT/CT对异位甲状旁腺的假阳性百分比低于MIBI平面(2.6% vs 19.6%,P < 0.05),SPECT/CT对异位甲状旁腺敏感性明显高于常位甲状旁腺(92.5% vs 67.0%,P < 0.05)。结论:SPECT/CT检查不能明显提高对甲状旁腺腺体定位诊断的敏感性,但明显减少假阳性,尤其对异位甲状旁腺有更高的临床应用价值。

    Abstract:

    Objective:To analysis the value of single-photon emission tomography/computed tomography(SPECT/CT ) in diagnosing parathyroid in patients with hyperparathyroidism. Methods:Thirty-five patients with secondary hyperparathyroidism (SHPT) were performed 99mTc-methoxyisobutylisonitrile(99mTc-MIBI) dual-phase planar scintigraphy (MIBI planar),and 46 focis outside of thyroid-bed were observed. SPECT/CT imaging including neck and additional radical uptake was added in them. The difference in sensitivity and false positive percent(FPP) between MIBI planar and SPECT/CT in finding the normalsite parathyroid and ectopic parathyroid were compared according to the pathology. Results:The sensitivity of MIBI planar in finding the normalsite parathyroid was similar to SPECT/CT(63.9% vs 67.0%,P > 0.05),the FPP was significantly lower than SPECT/CT(3.0% vs 18.4%,P <0.05). The sensitivity of MIBI planar in finding the ectopic parathyroid was similar to SPECT/CT(either 92.5%),the FPP was significantly lower than SPECT/CT(2.6% vs 19.6%,P < 0.05). The sensitivity of SPECT/CT in finding the ectopic parathyroid was significantly higher than itself in finding the normalsite parathyroid(92.5% vs 67.0%,P < 0.05). Conclusion:SPECT/CT can not add the sensitivity in finding parathyroid,but can significantly reduce FPP. It is very valuable in clinical work,especially in finding the ectopic parathyroid.
