Long examination time was one of the clinical issues of MR imaging, especially for acquiring T2-weighted images with spin-echo sequence. However, MR system has progressed recently and new techniques have become available. The, use of segmented k-space method greatly facilitated reduction of the examination time. We can obtain T2-weighted images in a few minutes with this technique in combination with spin-echo sequence called \"fast or turbo spin-echo (FSE or TSE)\" imaging. In addition, fluid attenuated inversion recovery imaging (FLAIR) is now also clinically acceptable with the method. On ELAIR images, T2-elongated lesions are demonstrated more distinctly as hyperintense areas in contrast with hypointense cerebrospinal fluid (CSF). Constructive interference in steady state (CISS) imagining is a gradient-echo sequence. CSF and lymph in the inner ear are markedly hyperintense on CISS images. Because of thin sections (\u003c 1 mm-thickness), thin nerves and vessels as well as inner ear structures are identified exactly on these images. Echo-planar imaging (EPI) is also clinically available. Diffusion-weighted images with EPI can demonstrate hyperacute infarction in a few seconds, which could not been detected with any other pulse sequences. Epidermoid cyst and brain abscess are markedly hyperintense on diffusion-weighted images. Therefore, diagnosis of the diseases is strongly supported with diffusion-weighted images. At present, MRI gives us not only Morphological information but also functional one of the brain.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name":
