【 摘 要 】

Category:AnkleIntroduction/Purpose:With the recent remarkable progresses in image diagnosis using magnetic resonance imaging (MRI), it could be possible to evaluate articular cartilage in detail. T1ρ mapping by MRI has recently drawn attention as a noninvasive cartilage evaluation method. While its validity has been proven, there are no reports describing T1ρ mapping for the ankle; therefore, in this present study, T1ρ values of the articular cartilage surfaces of the talar dome were measured in healthy individuals.Methods:The study sample comprised 10 ankles from 10 healthy volunteers (4 male and 6 female), with a mean age of 32.2 years. Images taken using a 3.0 T MRI device, manufactured by Philips, were processed using the PRIDE software (Philips, Inc.) and analyzed using Image J, a specialized analysis software. Evaluations were performed using slices in the coronal plane from the trochlear ridge of the talus and slices 10 mm anterior and posterior of the ridge. Each slice was divided into three equal...
