Multiplanar Reconstruction Technique for Difficult Computed Tomography-guided Lung Biopsy: Improved Accuracy and Safety

We assessed the value of the multiplanar reconstruction technique (MRT) for computed tomography-guided lung biopsy. We evaluated 72 difficult biopsy cases (traditional method = 44; MRT = 28) to compare patient and lesion characteristics, diagnostic accuracy, complications, radiation dose, and procedure duration. Diagnostic accuracy was significantly higher using MRT than the traditional method (100% vs. 84.1%, respectively; P = 0.038). There were no severe complications in the MRT group, but one case each of severe pneumothorax and fatal hemothorax in the traditional method group. The dose-length product rate was lower and the procedure duration slightly higher in the MRT than in the traditional group (336.83 vs. 479.64 and 33.39 vs. 25.93 minutes, respectively). MRT using computed tomography-guided lung biopsy could improve diagnostic accuracy and avoid severe complications compared to the traditional method.
