Abstract:
Objective To explore the MRI T 1WI features of the hyperacute intracerebral hematoma by super-low-field MR.Methods 160 patients with hyperacute intracerebral hematoma were examined by using MR unit of 0.04T magnetic(WDLMW-400) and PS3D T 1WI(TR=125 ms,TE=25 ms).Results Hematomas located in basal ganglia(140 cases),cerebral lobe(13 cases),cerebellum(5 cases) and brain stem ( 2 cases) respectively.All of the hyperacute hematomas showed short T 1 signal intensity in PS3D T 1WI;the mass effects and perihematoma edema also can be found in all of the 160 cases.Conclusion This study shows that the super-low-field MRI is superior to medium and high field MRI in diagnosis of hyperacute intracerebral hematoma.
