Abstract：Objective To explore the diagnostic value of the vascular convergence sign of solitary pulmonary nodule (SPN) on 3D reconstrucion. Materials and Methods Helical CT scans of 63 patients with SPN confirmed by pathology were reviewed and and analyzed.3D reconstruction was made using MPR and VR. Manifestation of the vascular convergence sign of the tumor was observed. A difference in the result was found between MPR and VR, benign and malignant SPN. Results: The rate of visualization of the vascular convergence sign of SPN in VR was higher than the one in MPR (P < 0.05). The rate of visualization of the vascular convergence sign in benign SPN was higher than the one in malignant (P < 0.05). Conclusion: 3D reconstrucion can demonstrate vascular convergence sign effectively. VR is an effective method for the differentiation of benign SPN with malignant lesions.
