| 内容記述 | Purpose To perform baseline T2 mapping of the hips of healthy volunteers, focusing on topographic variation, because no detailed study has involved hips. T2 mapping is a quantitative magnetic resonance imaging (MRI) technique that evaluates cartilage matrix components. \nMaterials and Methods Hips of 12 healthy adults (six men and six women; mean age = 29.5 +- 4.9 years) were studied with a 3.0-Tesla MRI system. T2 measurement in the oblique-coronal plane used a multi-spin-echo (MSE) sequence. Femoral cartilage was divided into 12 radial sections; acetabular cartilage was divided into six radial sections, and each section was divided into two layers representing the superficial and deep halves of the cartilage. T2 of these sections and layers were measured. \nResults Femoral cartilage T2 was the shortest (-20- to 20- and -10- to 10-, superficial and deep layers), with an increase near the magic angle (54.7-). Acetabular cartilage T2 in both layers was shorter in the periphery than the other parts, especially at 20- to 30-. There were no significant differences in T2 between right and left hips or between men and women. \nConclusion Topographic variation exists in hip cartilage T2 in young, healthy adults. These findings should be taken into account when T2 mapping is applied to patients with degenerative cartilage. |
