Smokers were at a higher risk of osteonecrosis
of the femoral head (ONFH).
In this study we aim to evaluate prognostic value of dynamic
magnetic resonance imaging in assessing the femoral head vascularity of male
smokers.
80 young adult men
of whom 40 were smokers and 40 were nonsmokers underwent routine MR and DCE MR examination. The images and data were analyzed. In this study, we found that there was no difference of T1WI and T2WI between smokers and
non-smokers.
Ktrans and Kep of femoral head in the smoking group were
higher compared to the control group.
DCE MR can be a potential tool to detect the early change of femoral
head vascularity of male smokers.
