磁敏感加权成像在轻型颅脑损伤患者中的诊断价值
Value of susceptibility-weighted imaging in diagnosis of traumatic bleeds for patients with mild traumatic brain injury
摘要
Abstract
Objective To investigate the sensitivity of susceptibility-weighted imaging ( SWI ) for detecting intracranial bleeds ( ICBs ) in patients with mild traumatic brain injury ( MTBI ) , and by comparing to that of conventional computed tomography( CT) and magnetic resonance imaging ( MRI) examine the diagnostic value of SWI in traumatic brain injury patients.Methods CT,MRI,SWI and clinical information of 32 MTBI patients( GCS 13-15) were collected, which were under treatment in our hospital.All patients were under the examination of CT scan, MRI scan and SWI within one week after the injury.Eliminating artifacts of gas, blood vessels and skull base by combining CT and phase diagram,low signals on SWI were demonstrated to be cerebral contusion hemorrhage.The number of lesions and location on the routine MRI sequence and SWI were recorded respectively,and were analyzed in combination with clinical symptoms.Results The sensitivity of SWI in detecting traumatic contusion hemorrhage in patients was significantly higher than the conventional CT and MRI scan, especially in patients with posttraumatic syncope and coma,or with continuous clinical symptoms.Conclusion SWI is more sensitive than conventional CT and MRI scan in detecting tiny contusion and hemorrhagic foci in MTBI patients, may offer valuable objective diagnostic information and has significant meaning to guide the clinical treatment and predict prognosis.关键词
