Comparison of ultrasound-guided and CT-guided percutaneous biopsy in diagnosis of chest lesions not blocked by bone nor lung / 中国介入影像与治疗学

ABSTRACT

Objective To compare the value of ultrasound guided and CT-guided percutaneous biopsy in diagnosis of chest lesions not blocked by bone nor lung.Methods A total of 244 patients with chest lesions not blocked by bone nor lung were collected and divided into ultrasound-guided group (n=114) or CT-guided group (n=130).The puncture success rate,biopsy success rate and the complication rate were compared between the two groups.Results The puncture success rate (98.25％ [112/ 114]) and biopsy success rate (96.49％ [110/114]) in ultrasound-guided group were higher than those in CT-guided group (86.92％ [113/130],79.23％ [103/130]),and the complication rate (3.51％ [4/114]) in ultrasound-guided group was lower than that in CT-guided group (16.92％ [22/130],all P＜0.01).Conclusion For chest lesions not blocked by bone nor lung,ultrasound is more secure and effective than CT for guiding percutaneous biopsy.
