Head Scans(头部扫描)研究综述
Head Scans 头部扫描 - Segmentation of Brain tumor from the magnetic resonance imaging (MRI) of head scans is an essential requirement for clinical diagnosis since manual segmentation is a fatigue and time‐consuming process. [1] Potentially, this combined diagnostic approach could achieve both high sensitivity and high specificity, thereby reducing the need of CT-head scans when managing these patients. [2] METHODS The authors included all patients who underwent FOA between 2014 and 2020 with individualized, CAD/CAM-based, 3D-printed templates and received postoperative 3D photographic face and head scans at follow-up. [3] A systematic random sampling method was used to select 300 normal computed tomography (CT) head scans of adult Ghanaians from the largest hospital in Ghana. [4] Interestingly, head scans were as predictive as gaze scans. [5] Objective: The study is aimed at optimizing the existing CT protocol for head scans in a Specialist Teaching Hospital in Edo State with a 16-slice Siemens Somatom Emotion scanner. [6] Among patients with migraine, 21% had computed tomography (CT) head scans, and 4. [7] This study assessed the impact of implementing this guideline on the proportions of computed tomography (CT) head scans, guideline adherence, and confidence level of the attending physicians. [8] For each patient scan, the SSDE was obtained using Dw and CTDIvol values of each scan, according to AAPM Report 220 for body scans and Report 293 for head scans. [9] This cohort-based panel study enrolled 746 participants aged 40 to 94 (396 males), from whom computed tomography (CT) head scans were acquired. [10] This study aimed to reduce the absorbed dose of sensitive organs in the head (eye lenses and thyroid) and to assess changes in resultant images quality in head scans when the radiation dose is decreased. [11] Craniometric data from computed tomography (CT) head scans of 287 living Americans of three descent groups (African, Asian, European) and both sexes were analyzed for measurement precision. [12] Mean effective dose calculated for thyroid gland in head scans by TLD and ImPACT was less than the annual permissive level for thyroid gland suggested by International Committee on Radiological Protection. [13] The preliminary result indicated that head scans for 10–15 years old patients require optimization. [14] All data are automatically derived from computed tomography (CT) head scans and optical face scans. [15] METHODS A total of 399 magnetic resonance imaging (MRI) and computed tomography (CT) requisitions for lumbar and head scans were reviewed and assessed for appropriateness in concordance with published Choosing Wisely guidelines for head and lumbar diagnostic imaging. [16]从头部扫描的磁共振成像 (MRI) 分割脑肿瘤是临床诊断的基本要求，因为手动分割是一个疲劳且耗时的过程。 [1] 潜在地，这种联合诊断方法可以同时实现高灵敏度和高特异性，从而在管理这些患者时减少对 CT 头部扫描的需求。 [2] 方法 作者纳入了所有在 2014 年至 2020 年间接受 FOA 的患者，这些患者使用个性化、基于 CAD/CAM 的 3D 打印模板，并在随访时接受了术后 3D 面部和头部照片扫描。 [3] 使用系统随机抽样方法从加纳最大的医院中选择了 300 例成年加纳人的正常计算机断层扫描 (CT) 头部扫描。 [4] 有趣的是，头部扫描与凝视扫描一样具有预测性。 [5] 目的：本研究旨在使用 16 层 Siemens Somatom Emotion 扫描仪优化江户州专科教学医院现有的头部扫描 CT 协议。 [6] 在偏头痛患者中，21% 进行了计算机断层扫描 (CT) 头部扫描，4. [7] 本研究评估了实施该指南对计算机断层扫描 (CT) 头部扫描比例、指南依从性和主治医师的信心水平的影响。 [8] 对于每次患者扫描，根据 AAPM 报告 220 的身体扫描和报告 293 的头部扫描，使用每次扫描的 Dw 和 CTDIvol 值获得 SSDE。 [9] 这项基于队列的小组研究招募了 746 名 40 至 94 岁的参与者（396 名男性），从他们那里获得了计算机断层扫描 (CT) 头部扫描。 [10] 本研究旨在减少头部敏感器官（眼睛晶状体和甲状腺）的吸收剂量，并评估减少辐射剂量时头部扫描结果图像质量的变化。 [11] 分析了来自三个血统群体（非洲、亚洲、欧洲）和两种性别的 287 名在世美国人的计算机断层扫描 (CT) 头部扫描的颅骨测量数据，以确保测量精度。 [12] TLD和ImPACT在头部扫描中计算的甲状腺平均有效剂量低于国际放射防护委员会建议的甲状腺年度允许水平。 [13] 初步结果表明，10-15 岁患者的头部扫描需要优化。 [14] 所有数据均来自计算机断层扫描 (CT) 头部扫描和光学面部扫描。 [15] 方法 共有 399 份用于腰椎和头部扫描的磁共振成像 (MRI) 和计算机断层扫描 (CT) 申请进行了审查和评估，以符合已发表的“明智地选择头部和腰椎诊断成像指南”的适用性。 [16]
Ct Head Scans Ct 头部扫描
Additionally, ACF defect area of relevant surgical cases following endoscopic transcribiform approaches were measured in immediate postoperative CT head scans with a radiological imaging software. [1] Non-contrast CT head scans provide rapid and accurate diagnosis of acute head injury; however, increased utilisation of CT head scans makes it difficult to prioritise acutely unwell patients and places pressure on busy emergency departments (EDs). [2] When comparing the group before the Sensor Reservoir and after the Sensor Reservoir insertion, there was a 75% reduction in number of CT head scans (P<0. [3] This study aims to review the use of CT head scans and adhe. [4] Finally, the SSDE was calculated for all the CT head scans performed in a 9-years period in patients aged from 0 to 18 years old. [5] Postoperative CT head scans were graded for accuracy of placement and intraventricular catheter length. [6] PATIENTS 142 patients with chronic hypoparathyroidism and CT head scans followed between 1/1/2000 and 7/9/2020, and 426 age- and sex-matched controls with CT head scans over the same interval. [7] Introduction The first Choosing Wisely Canada (CWC) recommendation for Emergency Medicine states: “Don’t order CT head scans in adults and children who have suffered minor head injuries (unless positive for a validated head injury clinical decision rule)”. [8] METHODS: We retrospectively analyzed baseline and follow up CT head scans of 14 men prior to and after initiation of ADT. [9] Background: ASPECTS (Alberta Stroke Program Early CT Score) is a validated scoring system for assessment of early ischemic change (EIC) on CT head scans, which can be used to guide patient manageme. [10] Baseline, 6 hours and 24 hours CT head scans were evaluated. [11] Baseline, 6 and 24 hours CT head scans were evaluated. [12] If the RCR 2017 guidance were to be introduced, an additional three CT head scans would be required per year and two skeletal surveys would be required for siblings or household contacts. [13]此外，使用放射成像软件在术后即刻 CT 头部扫描中测量了内窥镜下经式方法后相关手术病例的 ACF 缺损区域。 [1] 非对比 CT 头部扫描可快速准确地诊断急性头部损伤；然而，CT 头部扫描的使用增加使得难以优先考虑急性不适的患者，并给繁忙的急诊科 (ED) 带来压力。 [2] 比较 Sensor Reservoir 之前和 Sensor Reservoir 插入之后的组，CT 头部扫描次数减少了 75%（P<0. [3] 本研究旨在回顾 CT 头部扫描和粘附的使用。 [4] 最后，计算了 0 至 18 岁患者在 9 年内进行的所有 CT 头部扫描的 SSDE。 [5] 术后 CT 头部扫描根据放置的准确性和脑室内导管长度进行分级。 [6] 耐心 在 2000 年 1 月 1 日至 2020 年 7 月 9 日期间，对 142 名慢性甲状旁腺功能减退症患者进行了 CT 头部扫描，并在相同的时间间隔内对 426 名年龄和性别匹配的对照进行了 CT 头部扫描。 [7] 简介 加拿大明智地选择急诊医学的第一个建议指出：“不要对头部受轻伤的成人和儿童进行 CT 头部扫描（除非经过验证的头部受伤临床决策规则呈阳性）”。 [8] 方法：我们回顾性分析了 14 名男性在开始 ADT 之前和之后的基线和随访 CT 头部扫描。 [9] 背景：ASPECTS（阿尔伯塔中风计划早期 CT 评分）是一种经过验证的评分系统，用于评估 CT 头部扫描的早期缺血性变化 (EIC)，可用于指导患者管理。 [10] 评估基线、6 小时和 24 小时 CT 头部扫描。 [11] 评估基线、6 小时和 24 小时 CT 头部扫描。 [12] 如果要引入 RCR 2017 指南，则每年需要额外进行三次 CT 头部扫描，并且需要对兄弟姐妹或家庭接触者进行两次骨骼检查。 [13]

Human Head Scans 人体头部扫描
The proposed work introduces a fully automatic modified fuzzy c‐means (MFCM) algorithm for segmenting brain tissue into gray matter (GM), white matter (WM), and cerebrospinal fluid (CSF) which identifies the pathological conditions of magnetic resonance human head scans. [1] Experiments are conducted by applying this schemes on 38 volumes of MRI of human head scans collected from the Internet Brain Segmentation Repository (IBSR). [2]所提出的工作引入了一种全自动改进的模糊 c 均值 (MFCM) 算法，用于将脑组织分割为灰质 (GM)、白质 (WM) 和脑脊液 (CSF)，该算法可识别磁共振人体头部扫描的病理状况. [1] 通过将该方案应用于从互联网大脑分割存储库 (IBSR) 收集的 38 卷人体头部扫描的 MRI 进行实验。 [2]
