摘要

Objective To judge hilar tumors and their involvement range and improve the ability for the 3D plan of steric shape- fitting radiotherapy of pulmonary cancer dicide target area.Method Spiral CT dynamically enhanced scanning was used to localize the target area and distinguish pilar tumors,atelactasis,pilar blood vessels and enlarged lymphoid tissues,and define locus and involvement area.Result Local contour showed by spiral CT enhanced dynamically scanning was superior to that by common CT.Conclusion Spiral CT dynamically enhanced scanning is an ideal simulation for 3D conformal radiotherapy.
