摘要

多切面電腦斷層攝影檢查後利用影像處理技術重組二度空間冠狀面及三維空間立體影像，提供一個真實且可測量的影像對於支氣管鏡檢查(bronchoscopy)或電腦斷層導引下經皮穿刺細針生檢術(CT biopsy)提供路徑選擇的幫助，提供給醫師更多且更明確的影像資訊。有21名病患電腦斷層攝影儀檢查後發現肺臟有單一病灶，病患的最大年齡為81歲，最小年齡18歲，（平均年齡66.7歲）。在評比結果討論下橫切面(Axial view)、冠狀面(Coronal view)、三維空間立體影像(3-D image)分別得到不同的結果。放射科醫師對傳統橫切面影像較為熟悉，故在影像學幫助和經皮生檢幫助得到較高的評比。冠狀面、三維空間立體影像因為能呈現出整個支氣管所以在支氣管鏡檢幫助上可提供較佳的路徑選擇。影像處理技術不斷的增進，經由一次掃描可以呈現不同的影像，針對不同的檢查提供不同的影像，讓不同科別的醫師在執行取得病灶組織前獲得更多的影像資訊與幫助，以提高診斷的準確性。

Following multislice computed tomography (MSCT), two-dimensional coronal and three-dimensional views can be generated using special image-processing techniques. These realistic and measurable images can facilitate optimal path selection for bronchoscopy and CT-guided percutaneous needle biopsy, and also provide clinicians clearer and more detailed information. In the current study, a solitary lesion was demonstrated by CT scan in the lungs of 21 patients, 18-81 years of age (average, 66.7 years).When axial, coronal views and 3-D images were inter preted in dependently and compared, different results were obtained. Radiologists were more familiar with the traditional axial views, which in turn yielded more detailed comments as aids to imaging and CT-directed biopsy. The coronal views and 3-D images allow the visualisation of the entire bronchial tree, hence provide for superior path planning for bronchoscopy. The technology of imaging processing is ever-evolving. From a single scan, multiple different images can be obtained and displayed for various medical examinations, providing clinicians of different specialties additional information prior to the biopsy, and potentially improving overall diagnostic accuracy.
