Objective To investigate the diognostic value of multi-sllce helical CT(MSCT) in spinal tuber-culosis, and making a further understanding of this disease. Methods The MSCT and post-processing films manifes-tations of 23 spinal tuberculosis proved by operation and pathology were reviewed retrospectively. Results MSCT could show the bone destructions location, range, relationships with neighbor tissues, osseous vertebral narrowing and para-vertebral abscess,etc. MPR, CPR, SSD and VR could more completely and stereoscopically show these character-istics of spinal tuberculosis. Conclusion MSCT post-processing techniques could make up for the lack of axial CT scan. It has high value in elevating the diagnosis accuracy of spinal tuberculosis.

Objective To evaluate the X-ray diagnosis value of intestinal malrotation in adults.Methods The X-ray findings of 16 cases with intestinal malrotation confirmed by surgery were analyzed retrospectively. All of them were taken X-ray plain films, 11 cases were taken alimentary tract barium meal,and 5 cases were taken barium enema. Results Eight cases were found incomplete obstruction of the duodenum, and 2 cases were found low small intestine obstruction on the X-ray plain films. The alimentary tract barium meal showed 4 cases with dilatation and incomplete obstruction of the duodenal bulb to horizontal segment,and the distal end of narrowing intestine appeared as a rat tail,7 cases showed the abnormal duodenal location and shape,called "strip" sign. Four cases were found abnormal duodenojejunal flexure by barium enema examination. Conclusion The alimentary tract barium meal and barium enema examination has great diagnosis value for intestinal malrotation in adults.
