Objective To investigate the application value of direct digital radiograph(DDR) in lumber spine.Methods Lumber spine of 81 cases was examined by DDR. All digital images were post-processed withMUSICA (multi-scale image contrast amplification).The lumber spine image data by conventional radiography of another 81 cases were collected.All images were analyzed and diagnosed by two experienced radiologists and two technicians.The image quality was evaluated by marks through routine standard.Results(1) The image quality marked by DDR was 13.00,and by conventional radiography was 8.96.There was a significant difference between two methods by Wilcoxon Signed Ranks Test(Z=-7.88,P0.01).The image quality of DDR was much higher than that of conventional radiography.(2) Satisfactory rate of lumber spine lmage was 92.6%(75/81) in DDR,and 61.7%(50/81) in conventional radiography(χ~2 = 21.89,P0.01).Conclusions DDR provides the lumber spine with better quality in showing lower lumber spine,lumber appendage and soft tissue than conventional radiography.DDR will facilitate the accurate diagnosis of lumber spine.
