中文摘要 | 腦部電腦斷層檢查是偵測顱內瘤的利器,本研究比較台灣顱內瘤在腦 部電腦斷層檢查臨床使用前後發生頻度的變化,電腦斷層檢查使用後,腦模瘤 (24.2%)及腦垂體腺瘤(21.1%)發生頻度明顯增加,電腦斷層檢查使用前,腦膜瘤 為14.5%,腦垂體腺瘤為7.7%。然而惡性原發性顱內瘤的發生頻度相對降低, 神經上皮瘤(neuroepithelial tumors)在電腦斷層使用前為36.0﹪,使用後為23.9 ﹪。本研究顯示電腦斷層檢查使用後對於生長緩慢的良性顱內瘤偵測能力改善。 |
英文摘要 | The improved giagnostic capacity of computed tomography (CT) may haveresulted in improved detection of intracranial tumors. We were interested to know whether the frequency of intracranial tumors has changed after the introduction of CT in Taiwan. The relative incidences of intracranial tumors in Taiwan were analyzed from the hospital based data. Our data showed that meningiomas were the most encountered intracranial tumors. Neuroepithelial tumors in our series (in the post-CT era) (23.9%) were apparently lower than those found in the pre-CT era (36.0%). However , the relative incidences of meningiomas and pituitary adenomas after the use of CT (24.2%,21.1%,respectively) were much higher than those found before the use of CT (14.5%,7.7%,respectively). Our data suggest that the increased incidence for benign tumors and the decreased incidence for ma lignant tumors may have resulted from the improved diagnostic capacity of CT,which reduces the number of undected tumor cases. |
