Microvascluar perfusion abnormality and ischemia
condition could be an important risk factor for the
clinical assessment of hypertrophic cardiomyopathy(HCM).
We preliminarily investigate the difference of
myocardial microvascluar perfusion between HCM patients
and normal volunteers with low-multi-b
values(0,20,50,100,200 s/mm2) diffusion weighted
imaging. We found that the measurement parameters
reflected microvasluar perfusion (Standard ADC, Slow
ADC, Fast ADC and fraction of Fast ADC value)in HCM
patients were significant lower than that of normal
volunteers. We conclude that low-multi-b values
diffusion weighted imaging could quantitatively and
noninvasively evaluate the perfusion status in HCM
patients .
