Objective To explore the value of multi-slice spiral CT multiplanar reconstruction (MPR) technology in CT-guided percutaneous needle biopsy of pulmonary nodulars. Methods Fifty patients with pulmonary nodules underwent CT-guided percutaneous needle biopsy with Toshiba 64-slice spiral CT. All patients were divided into two groups, i.e. test group (MPR group) and control group (axial group). In the puncture course, three-axis vector direction reconstruction were made in MPR group, while the control group using only axial images. The data of the two groups of times of adjust needles during surgery and postoperative complications were recorded and analyzed. Results Biopsy was succefully done in all 25 patients in MPR group. In axial group, biopsy was failed in 1 patient due to lung bullae rupture; the average adjust needle time in MPR group was 1; three patients had minor bleeding; 1 had small amount of pneumothorax. In axial group, the average adjust needle times was 3; 4 patients had minor bleeding; 6 had small amount of pneumothorax. Conclusion Multi-slice spiral CT MPR axial, sagittal and coronal reconstructions can improve the puncture successful rate and reduce the complications during CT-guided percutaneous needle biopsy of pulmonary nodules.
