摘要

虛擬內視鏡是利用螺旋電腦斷層攝影，由電腦將二度空間影像的資料，轉換成三度空間的虛擬影像。因其不具侵襲性，且可在很短時間完成，對於執行傳統內視鏡有困難之病變是一項診斷利器。本院經歷一黏多醣堆積於聲門上方及氣管壁，而造成呼吸困難的病人，因多處氣道狹窄，使得內視鏡作氣道評估不易且有危險。我們嘗試虛擬內視鏡加以檢查，並將此和傳統內視鏡的影像比較。

With improvements in computer technology, noninvasive virtual endoscopy provides 3-dimensional (3-D) anatomical information by reconstructing 2-D imaging data from computed tomography or magnetic resonance imaging. Virtual endoscopy is particularly helpful for the assessment of the airway. We present a 17-year-old man who had multiple airway stenoses due to mucopolysaccharide deposition supraglottically and on the tracheal wall. Due to the potential risks of rigid endoscpy and general anesthesia, virtual endoscopy was arranged for the patient. Virtual endoscpy allowed not only for accurate presurgical evaluation of the airway anatomy, but also provided information for future bronchoscopic procedures such as placement of tracheobronchial stents. Virtual endoscopy identified a supraglottic mass caused by mucopolysaccharide depositioin, a circumferential stenosis at the glottic level due to previous CO2 laser vaporization, and tracheal wall stenosis. Virtual endoscopy provided a good simulation of endoscopy. The advantages, disadvantages, potential indications, and future roles of virtual endoscopy are discussed.
