项目摘要
The disorders of the salivary glands and its circumference are one of the diseases that we need a lot of information in addition to image examination to diagnose correctly. A purpose of image examination is different by the kind of a lesion. For one example, in case of tumor nature lesion, it is important to exam a position of a lesion, a bad degree and relation of a position with a blood vessel and the nervous system. For another, in case of inflammation and autoimmune disease, a change of a salivary glands organization and a function of that become important point of an examination. Examination of MR imaging is the method that is necessary for image examination of a disorder to appear in salivary glands and the circumference disorders. I suggest optimization of MR for image examination by making an examination procedure of a disorder to appear in salivary glands and the circumference clear. First arranging and integrate information of the image characteristic of each disorder. Then a … More utomating calculation such as statiscal manifestation frequency or conformity rate of a disorder so long as possible.The purpose of these works is helping your image diagnosis. For a disorder to appear in a salivary glands and the circumference, carried out sonography before MR image examination, and judged a tumor nature or inflammation nature lesion, and an inflammation nature lesion did an Axial image (T1, T2, T2-fat), and added a Coronal image (T1) on the occasion of tumorous lesion about optimization of image examination in a principle. In this study, I focus the examination that did not increase inversion of contrast medium. I took normal salivary glands (parotid gland: 89 glands, submandibular gland: 82 glands) and settled tumorous lesion (41 cases), inflammatory lesions (67 cases) and autoimmune disease of diagnosis as an object of study. It became possible to limit a liquid ingredient of high signal domain of T2 image more by adding T2-fat suppression and on a disorder intended for this time, the effectiveness was high. Especially, for Sjogren's syndrome and metastases to lymph nodes case the examination became possible that precision was high by T2-fat.On MR-sialography, while it was advantageous that I could observe form any kind of direction with 3D image (MIP), the search of the salivary glands was high of an image of 1 slice of 20mm when the signals were weak. As a result, I decide that I use 3D image (MIP) for the tumorous lesions and the image of 1 slice of 20mm for inflammatory lesions. I thought about the use of a diffusion image as means to keep objectivity in image information, but because a use period was limited, then I switched the policy. I considered the image factor that seems to be useful for discrimination diagnosis from a saved image. I expressed equality of the image of the each pixel signal strength of the salivary glands and lesion parts did not receive influence such as window width or level very much. In sjorgren's syndrome, I had a meaningful difference between normal salivary glands and sialoadenitis. I could take advantage of it as an index of a discrimination diagnosis. There were a few cases, but it was expected that we could use it for discrimination of an inflammatory lymph node and metastasis lymph node. Less
唾液腺及其周围的疾病是疾病之一,除了影像检查之外,我们还需要大量信息才能正确诊断。图像检查的目的根据病变的种类而不同。例如,在肿瘤性质病变的情况下,重要的是检查病变的位置、不良程度以及该位置与血管和神经系统的关系。另一方面,在炎症和自身免疫性疾病的情况下,唾液腺组织及其功能的变化成为检查的重点。 MR成像检查是对唾液腺中出现的疾病和周围疾病进行图像检查所必需的方法。我建议通过明确唾液腺和周围出现的疾病的检查程序来优化图像检查的MR。首先对各疾病的图像特征信息进行整理和整合。然后尽可能长时间地进行自动化计算,例如统计表现频率或疾病的符合率。这些工作的目的是帮助您进行图像诊断。对于唾液腺和周围出现的病变,在MR图像检查之前进行超声检查,判断肿瘤性质或炎症性质病变,炎症性质病变做轴向图像(T1、T2、T2-脂肪),并且在肿瘤病变时添加冠状图像(T1)关于图像检查的优化原则上。在本研究中,我重点关注不增加造影剂反转的检查。以正常唾液腺(腮腺:89个腺体,颌下腺:82个腺体)和已诊断的肿瘤性病变(41例)、炎症性病变(67例)和自身免疫性疾病为研究对象。通过添加T2脂肪抑制,可以进一步限制T2图像的高信号域的液体成分,对于这次针对的疾病,有效性很高。特别是,对于干燥综合征和淋巴结转移病例,通过 T2-fat 可以进行高精度检查。在 MR-唾液造影中,虽然可以通过 3D 图像 (MIP) 从任何方向观察是有利的,但当信号较弱时,唾液腺的搜索比 1 片 20mm 的图像高。因此,我决定对肿瘤性病变使用 3D 图像 (MIP),对炎症性病变使用 1 片 20mm 的图像。我曾想过使用扩散图像作为保持图像信息客观性的手段,但由于使用期限有限,所以我改变了策略。我考虑了似乎对保存图像的判别诊断有用的图像因素。表现了唾液腺的各像素信号强度的图像的均等性,病变部没有受到窗口宽度或水平等的影响。在干燥综合征中,我发现正常唾液腺和唾液腺炎之间存在显着差异。我可以利用它作为歧视诊断的指标。虽然有一些病例,但我们希望可以用它来区分炎症淋巴结和转移淋巴结。较少的
