摘要

目的：頭頸部腫瘤與其周圍相關位置的解剖構造相當複雜，因而放射科和外科醫師在看傳統的電腦斷層掃描攝影(CT)圖像時，從中想像其立體的構造有時會有困難，本研究的目的在於利用CT之三度空間立體的影像重組，並於腫瘤上標記顏色，應用於術前的診斷。病人及方法：從民國88年至1月到88年6月，吾原收集了14例頭頸部腫瘤的個案(11位男性：3位女生；年齡從4歲到86歲)並加以分析。我們採用一台獨立的工作站，以分段的體積資料進行彩色立體灰階陰影的重組。再由不同角度旋轉的觀察，使我們得以感受到此一三度空間立體的影像，以及腫瘤和周圍骨頭之間的關系。結果：在三度空間立體圖像顯示下，吾等一眼便可以出相當顯著又突出，被標記成紅色的腫瘤。那紅色的腫瘤與周遭白色的骨頭間相關位置，侵犯的程度都可以一覽無遺。結論：因而吾等認為以三度空間立體顏色標記的方法，應用於頭頸部的腫瘤，提供了清楚的解剖以及診斷上的訊息，遠遠勝過傳統的斷層掃描攝影，不但能更加了解頭頸部腫瘤對於骨頭侵犯的情形，同時也有助於術前計畫的擬安及病人衛教工作的進行。(慈濟醫學 2000;12:25-30)

Objective: The anatomical relationship of a neoplasm in the face to adjacent structures in so complex that radiologists and many surgeons have a difficult time assimilating cross-sectional imaging into a complete picture of the true extent of bone involvement using conventional computed tomography (CT). This study was undertaken to demonstrate the usefulness of three-dimensional (3D) color-encoded tumor CT imaging in preoperative evaluation. Patients and Methods: From January 1999 to June 1999,frouteen cases of carniofacial tumors (11 male:3 female; from 4 to 86 years old) were collected and analyzed. We rendered the segmented volumetric data with a gradient shading color protocol at an independent workstation by encoding the “white” of the bone and the “red” of the tumor. Dynamic cine observation with changing viewpoints allowed us to perceive 3D shapes and the relationships of the tumor with the surrounding bones. Results: On the 3D display, the outstanding “red” mass could be seen clearly at a glance. The involvement, extension and relationship between the “red” tumor and adjacent “white” bone could be easily evaluated. Conclusion: Three-dimensional color-encoded CT imaging offers greater anatomical and diagnostic illustration than conventional CT, improving understanding of bony invasion by craniofacial malignancy and providing a useful adjunct to preoperative planning and patient education.
