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.

ABSTRACT

Objective To compare the puncturing hit rate,positive rate of pathological diagnosis and the incidence of complications between color Doppler ultrasound-guided and CT-guided percutaneous biopsy for the qualitative diagnosis of ultrasonic-visual chest lesions.Methods A total of 112 patients,who were encountered from January 2015 to June 2016 in authors' hospital and whose imaging materials suggested the presence of ultrasonic-visual chest lesions,were enrolled in this study.There were no bones or lung air between the thoracic skin and chest lesion to hinder imaging observation.Ultrasound-guided puncturing was employed in 52 patients (ultrasound-guided group) and CT-guided puncturing was adopted in 60 patients (CT-guided group).The puncturing hit rate,positive rate of pathological diagnosis and the incidence of complications were compared between the two groups.Results The puncturing hit rate in ultrasound-guided group was 100% (52/52),which was higher than 91.7% (55/60) in CT-guided group.The positive rate of pathological diagnosis in ultrasound-guided group was 96.2% (50/52),which was higher than 80.0% (48/60)in CT-guided group.The incidence of complications in ultrasound-guided group was 3.8% (2/52),which was lower than 18.3%(11/60) in CT-guided group.Conclusion For the qualitative diagnosis of ultrasonic-visual chest lesions,ultrasound-guided percutaneous biopsy is more reliable than CT-guided percutaneous biopsy.
