摘要：

High resolution magnetic resonance imaging studies on skin have been limited by their inability to detect the low-moisture-content outer layers near the surface of the stratum corneum, The hydration of these outer layers is especially important physiologically. The present study shows that by using a short echo time of 5 ms it becomes possible to observe these layers in all but a few individuals with exceptionally dry skin, The quality of the images can be further improved by the use of separate transmit and receive coils, which reduces the rapid fall-off in signal intensity encountered with a single surface coil used both to transmit and receive.
