【Abstract】 Objective To evaluate clinical application of deep tissue aspiration biopsy directed by CT.Method Deep lesion tissues were scanned by CT, and body surface locations of lesions, points of puncture, angle and depth were determined. 18～20G tissue cutting biopsy needle (Cook Corporation, USA) was utilized. After the tip of the needle went to the proper place determined by CT scan under local anesthesia, pathological tissues were taken and pathologically observed.Result 59 aspiration biopsies were taken from 32 lesions including lung, liver and mediastium. Pathological diagnoses of 28 lesions were confirmed and the rate of confirmed diagnosis was 87.5%. No serious complications took place.Conclusion This technique has high sensitivity for diagnosis, few traumas for examination and low complications.更多还原
