15位病患因副甲狀腺功能過高,於手術前進行四種定性照影:(1)鉈-鎝刪除性掃描,(2)超音波,(3)電腦斷層攝影,以及(4)磁振造影。對於定位異常變大之副甲狀腺的診斷率,鉈-鎝刪除性掃描為60%,電腦斷層攝影為33.3%,磁振造影為71.4%。本研剛顯示,至今仍無一種照影技術有足夠的可靠性,以定位副甲狀腺功過高患者之變大的副甲狀腺。
A total of 15 patients who underwent total neck exploration for hyperparathyroidism were studied with four different imaging modalities: (a) T1-201/Tc-99m subtraction scan (SS), (b) ultrasonography (US), (c) computed tomography (CT) and (d) magnetic resonance imaging (MRI). Accuracy for locating enlarged parathyroid(s) was 60.0% by SS, 60.0% by US, 33.3% by CT and 71.4% by MRI. Our results suggested that at present none of the imaging modalities was adequate on its own to locate all enlarged parathyroid gland(s) in patients with hyperparathyroidism.
