Objective To investigate the diagnosis value of traumatic focal cerebral hemorrhage in early stage by the low field MRI, in order to provide reference for clinical treatment. Methods A low magnetic field MRI was underwent in patients confirmed with focal cerebral hemorrhage after injury. Scan sequences such as axial T1WI, T2WI, FLAIR and DWI were included. Results By the low magnetic field MRI, low, equal or mixed signal was showed in T1WI, high or mixed signal in T2WI; FLAIR showed similar signal as T2WI but was more sensitive. DWI showed high-low or equal-low mixed signals. Conclusion Low field MRI findings for most of the early focal cerebral hemorrhage were consistent with the clinical manifestations. Low magnetic field MRI plain scan could provide traumatic focal cerebral hemorrhage with imaging evidence. Therefore, it was a necessary supplementary examination for traumatic patients whose CT examination showed negative.
