ABSTRACT
Objective To discuss clinical value of 64-slice spiral CT scanning in fast evaluation of severe multiple trauma.Methods A retrospective study was carried out on data of 72 multiple trauma patients diagnosed with systemic 64-slice spiral CT scanning in our hospital from January 2006 to June 2008.Of all,28 patients with traffic injuries,24 with falling injuries,10 with blunt injuries,6 with stab injuries and 4 with explosive injuries.Results There were 72 multiple trauma patients with mean scanning time of 10.2 seconds.The CT scanning showed both craniocerebral and thoracic injuries in 30 patients,brain injuries in 16,thoracoabdominal injuries plus pelvic injuries in 10,extremity and brain injuries in 14 and systemic soft tissue injuries in 2.Isotropic characteristics and postprocessing function of 64-slice spiral CT scanning could accurately diagnose and evaluate injury severity of multiple trauma.Conclusions 64-slice spiral CT scanning is a fast and effective method for fast evaluating injury severity of multiple trauma,for it can not only shorten checking time,reduce movements of the patients and relieve the pain of the patients,but also can avoid defects induced by respiratory movement and provide fairly integrated imaging materials by its isotropic characteristics and pestprecessing function.
ABSTRACT
The quality of CT diagnosis depends on the quality of scanning which is related to accurate scanning design and quality control on work process. The quality control of work procedure includes training of patients' breathing, reasonable application of window technique, accurate mark, size and CT value,washing and print of films. In addition, the coordination of clinical doctors, imaging doctors and CT technicians is very important. According to CT standards, precise CT scanning by CT design request, can provide a high quality CT images that reflect pathologic state of human body, thereby to raise the quality of CT diagnosis.
