title: [Multislice CT (MSCT) in the detection and classification of pelvic and acetabular fractures].
abstract: OBJECTIVE
  To assess the usefulness of MSCT in the detection and classification of pelvic and acetabular fractures.
  
  
  METHODS
  Routine radiographs and MSCT of the pelvis with sagittal and coronal multiplanar reconstruction (MPR) were performed in 50 patients with clinically suspected pelvic or acetabular fractures. One trauma surgeon and a radiologist evaluated routine radiographs and CT images in terms of fracture detection, classification and visualization. The AO classification of fractures was used.
  
  
  RESULTS
  MSCT excluded a suspected fracture in 15 patients. In the remaining 35 patients, 19 anterior pelvic ring fractures, 10 anterior and posterior pelvic ring fractures, 8 acetabular fractures and 4 sacral fractures were diagnosed. All MSCT diagnoses were made from the axial source images. In 7 (17 %) patients, MSCT detected additional fractures (2 acetabular and 5 posterior pelvic ring fractures) not seen on conventional radiographs. In 3 other patients, MSCT changed the fracture classification by delineating the full extent of the fracture. MPR visualized 7 acetabular and 4 sacral fractures better than the axial source images.
  
  
  CONCLUSIONS
  MSCT of the pelvis is needed for correct fracture detection and classification and has therapeutic consequences.
