Multi-slice spiral CT three-dimensional imaging and perfusion imaging in acute brain injury of dynamic application

Abstract

Objective Discussion of ultrathin multilayer spiral CT 3D image reconstruction,skull and brain perfusion imaging in acute brain injury to dynamic changes in the clinical value.Methods 2009December to 2011 October were collected in our hospital in 245 patients with acute traumatic brain injury patients check information,both in the 3-6 h after injury within conventional multislice spiral CT,thin multilayer spiral CT and three-dimensional image reconstruction of skull and brain CT perfusion imaging examination,all the cases in 2 to 7 days after injury dynamic review of conventional MSCT and ultrathin multilayer spiral CT,the data were retrospectively analyzed,using the chi-squared test evaluation.Results Super thin multilayer spiral CT in cerebral contusion and laceration,intracerebral hematoma in TBI with mixed diagnosis has statistics difference is better than the conventional MSCT.CTP in acute traumatic brain injury diagnosis was superior to conventional MSCT except diffuse axonal injury.CTP in cerebral contusion and laceration,subdural hematoma and intracerebral hematoma associated with intracerebral hematoma in the diagnosis with statistical difference,better than the ultrathin multilayer spiral CT (P ＜ 0.05).The 3D image reconstruction of skull fracture demonstrated great advantages in the treatment of skull fracture,which include cranial suture separation and basal skull fracture.Conclusion combined Super thin multilayer spiral CT 3D image reconstruction skull and brain CT perfusion imaging for acute craniocerebral injury early diagnosis and minimal injury diagnosis is superior to conventional multislice spiral CT,The rate of misdiagnosis can be decreased.which provide Reliable basis for early diagnosis and Prognosis of TBI.
