ABSTRACT
Objective To investigate the relationship between microvessel density (MVD), clinicophathological characteristics and the prognosis in brain astrocytoma. Methods To determine the generation level of microvessel in 52 cases brain astrocytoma with immunohistochemistry. Results MVD in brain astrocytoma tissues was higher (71.8?27.8) than that in normal brain tissues (25.8?6.2) (P
ABSTRACT
Objective To discuss the diagnostic value of multi-slice spiral CT 2D and 3D reconstruction for atlantoaxial occult fracture.Methods Multi-slice spiral CT scans were performed in 38 patients who were suspected of fracture but were not detected with radiography,and the images were post-processed with Vitrea workstation(including MPR,MIP,VR and SSD).The images were observed by two experienced radiologists.Results Of 38 cases,28 cases were detected having small fractures with spiral CT reconstruction.Conclusion Multi-slice spiral CT 2D and 3D reconstructions are of important value in diagnosing atlantoaxial occult fracture.
