Clinical Application of Diffusion-weighted MRI of Encephalic Infectious Disease / 医疗卫生装备

ABSTRACT

Objective To assess clinical applications of using diffusion-weighted imaging(DWI) in encephalic infection diseases.Methods 10 patients with encephalic infection diseases were investigated from September 2004 to June 2007.All patients underwent routine MRI and single-shoot DWI in which the thickness and space of routine MRI agreed with DWI.The ADC values at infection focus and opposite normal region were measured.Results Among the 10 cases,seven of them showed decreased ADC value when DWI presented hyper-intensity;whereas the other three,whose chronic infection were long-term,had increased ADC value while DWI presented iso-/hypo-intensity.Conclusion MRI diffusion-weighted imaging plays an important role in the diagnosis of encephalic infection diseases.
