Abstract
To discuss the diagnostic value of multislice spiral computed tomography ( MSCT) and its post-processing technique of occult fracture. Methods 48 cases with trauma from December 2010 to December 2011 in our hospital were divided into two groups. Group A was examined by X-ray (CR, DR); group B was the patients with negative results by X-ray, however, they had clinical signs or suspected for acute trauma, examined by MSCT scanning and deal with CT image processing software in the workstation processing, then obtained high-resolution two-dimensional reconstruction of MPR and MIP images or SSD and VRT images, after that they were read by physician in radiology department for the diagnosis of fracture phenomena. The diagnostic results were compared between the two groups. Results Croup A showed 10 cases with fracture phenomena, the positive rale was 20. 8% (10/48); group B showed 42 cases with fracture, the positive rate was 87. 5% (42/48). 6 cases were rib fractures, 4 cases were scapula fracture, 9 cases were hip fractures, 12 cases were knee fractures, and 10 cases were ankle and foot tarsal fractures, 5 cases were femoral neck fracture and 2 cases were pelvic fractures; the difference was significant (P<0.05). Conclusion MSCT and its post-processing technology for occult fractures is an effective detection, and it has important value for treatment options and prognosis estimated.关键词
