Abstract:
Objective To understand the bronchovascular nodule notch sign based on pathology and to evaluate the potential role in detecting this "sign"by multiplanar reconstruction(MPR).Methods ① 91 cases of small peripheral lung cancer (SPLC) and 55 cases of benignant nodule,confirmed by pathology were analysed.11 fresh lobectonic specimens including 9 cases with SPLC and 2 cases with benignant nodule were collected to make the gross pathologyical sections.The bronchovascular convergences in benign and malignant nodule were analysed comparatively.② MPR in 20 cases with malignant nodule and 13 cases with benign nodle were performed in order to observe the bronchovascular convergences.Results ① The specialty of nodule notch sign was 95.2% for malignant tumors.② The detecting rate of nodule notch sign on MPR in malignant nodule was 70%,which was of significant difference between MPR and plain CT scan.Conclusion "Notch sign" is of important value in the diagnosis of SPLC associated with BVC.The detected rate of "notch sign"will be improved by spiral CT MPR.
