Clinical application of diffusion-weighted imaging in CT-guided lung mass aspiration biopsy
Objective To explore the application value of magnetic resonance diffusion-weighted imaging(DWI)in CT-guided lung mass aspiration biopsy.Methods We retrospectively analyzed 152 patients who had undergone CT-guided lung mass puncture at the Affiliated Hospital of Shaanxi University of Traditional Chinese Medicine from October 2022 to October 2023 and divide them into group A(without DWI,n=85)and group B(with DWI,n=67)based on the presence of preoperative chest DWI examination,then compared the baseline data,pathologic positivity rate,number of needle adjustments,target skin distance,length of trocar in the lung,and complications between the two groups.Results The pathological diagnosis of group A was malignant tumors in 65 cases,benign lesions in 9 cases,and unspecified diagnosis in 11 cases,while the pathological diagnosis of group B was malignant tumors in 57 cases,benign lesions in 8 cases,and unspecified diagnosis in 2 cases;and the pathology-positive rates in group A and group B were respectively 87.06%and 97.01%,which were statistically significant(P= 0.029).The difference between the total complication rate and pneumothorax rate of the 2 groups was not statistically significant,but the hemorrhage rate of group A and B was successively 30.59%and 13.43%,with statistical significance(P<0.05).Conclusion Chest DWI examination before CT-guided lung mass puncture biopsy,with good clinical practical value,can contribute to guiding the selection of the puncture target point,improving the positive rate of pathological diagnosis,and reducing the occurrence of puncture-related bleeding.
