这e-Anatomy的解剖学单元显示使用MRI对健康病人的眼眶进行解剖。眼眶包括眼球、眼外肌、泪腺和视神经。这解剖单元集中显示眼睛的正常解剖结果,包括眼窝、颅骨、眼外肌、眼眶和眼球的筋膜、眼睑,以及支配眼睛运动、感觉和自主结构的六条颅神经(视神经(CN II)、眼球运动神经(CN III)、耳蜗神经(CN IV)、三叉神经(CN...
All personnel that are non-MR desiring to go into zone III must first pass the process of safety screening of MR. Only personnel of MR are given authority to perform MR safety screening before allowing personnel that are non-MR into zone III The forms for screening forms and process of scr...
They are to becharged with ensuring that this MR safe practiceguideline is strictly adhered to for the safety of the patients and other non-MRpersonnel, the health care personnel, and the equipment itself. Zone III regions shouldbe physically restricted from generalpublic access by, for example...
or braid the lead with other leads. Implant of the system cannot be performed in an MRI site Zone III (and higher). Take care to obtain appropriate electrode position. Failure to do so may result in suboptimal lead measurements. Unless all of the MRI Conditions of Use (as desc...

The ACR MR Safety Committee (2020) requires all MRI facilities to have a ferromagnetic detector before one may enter zone III, and the use of such a detector should be coupled with a visual safety inspection. Apart from screening using ferromagnetic detectors, Keevil [10] recommends that MR ...
Gray-level distance zone matrix (GLDZM) is a ‘‘hybrid’’ of textural and morphologic features and involves small-distance high-gray-level emphasis. Neighborhood gray-tone difference matrix (NGTDM) refers to the sum of differences between the mean gray level of a pixel or voxel and that of...
