原始语种摘要: OBJECTIVES: The objective of this study was to prospectively investigate the usefulness of chemical-shift and diffusion-weighted (DW) magnetic resonance imaging (MRI) in patients with myasthenia gravis (MG) for distinguishing thymic lymphoid hyperplasia (TLH), normal thymus (NT), and thymoma (THY) by using the signal intensity index (SII) and the apparent diffusion coefficient (ADC). MATERIALS AND METHODS: We examined 87 subjects (44 males, 43 females; range, 15–71 years) with generalized MG and antibodies to the acetylcholine receptor seropositivity who underwent surgery. They were divided into a TLH/NT group (A, 64 patients; TLH, 49; NT, 15) and a THY group (B, 24 patients; nonadvanced THY, 15; advanced THY, 9) on the basis of histological findings. One patient with contemporary...
