Periodically rotated overlapping parallell lines with enhanced reconstruction-diffusion weighted imaging における Apparent Diffusion Coefficient 値の検討 A Study of ADC Value in PROPELLER DWI

Diffusion weighted imaging(DWI)is rapidly becoming widespread in MRI, with many reports of the differential diagnosis using the Apparent Diffusion Coefficient(ADC)being seen. We examined the influence of scan parameter on ADC in PROPELLER-DWI. Neither the TR nor T1 value had a major influence on the ADC value. Number of MPG pulse, effective TE, and T2 value were the factors in which the ADC value was changed. In addition, the ADC value has been changed by the scan sequence. The factor that influenced the ADC value was able to be confirmed by this experiment. It is necessary to understand the influence that an individual factor has on ADC.
