The diagnostic values of multidirectional diffusion weighted image and apparent diffusion coefficient in acute brainstem infarction / 中国基层医药

ABSTRACT

Objective To investigate the diagnostic value of multidirectional diffusion weighted image (DWI) and apparent diffusion coefficient(ADC) image in acute brainstem infarction.Methods 24 cases of brainstem infarction included 2 cases in super acute stage,22 cases in acute stage.All cases were performed multidirectional DWI,ADC and T1 WI、T2 WI examination including of 2 cases of midbrain,21 cases of pons and 1 case of medulla.All of them were accompanied with infarction of other location.Results Among 24 cases there were 13 cases that their lesions displayed clearly and established by transverse T2WI,transverse、coronary or sagittal DWI、ADC and the diagnostic accuracy was 54.2%.In other 9 cases(37.5%) could not display the signal and extent of the lesions,but they could be confirmed by transverse、coronary or sagittal DWI 、ADC.Moreover there were 2 cases(8.3%) who were indicated accurately the diagnosis by coronary、sagittal DWI 、ADC.Conclusion Multidirectional DWI and ADC could show the location of lesions in the lower brainstem so the multidirectional DWI and ADC scan could be an excellent method for the diagnosis of the brainstem infarction.
