Fdg Pet Scans(Fdg 宠物扫描)研究综述
Fdg Pet Scans Fdg 宠物扫描 - When tumor growth was confirmed on MRI, 2-[18F]FELP, [18F]FET and [18F]FDG PET scans were acquired on three consecutive days. [1] We propose a two-stage deep learning framework to support the clinical evaluation of patients with focal epilepsy by identifying candidate regions of hypometabolism in [18F]FDG PET scans. [2] All analyses are conducted on 67 [18F]FDG PET scans with arterial blood data available for comparison. [3] MethodsThe 18F-FDG PET scans of 49 cancer patients and 48 normal controls were included. [4] In the ‘dual PET’ study, PiB and FDG PET scans are investigated in AD and other dementias. [5] Various imaging modalities, including MRI, CT angiogram, and FDG PET scans have been implicated in the diagnosis of LVV. [6] This highlights the importance for careful standardization of β-value used for serial 18F-FDG PET scans when following-up NSCLC patients. [7] Currently, quantitative analysis of FDG PET scans is limited to simple metrics like maximum standardized uptake value, metabolic tumor volume, or total lesion glycolysis, which have limited predictive value. [8] Exploratory endpoints are feasibility of sequential 18F-FES PET scans for assessment of ER expression and functional status during treatment, value of 18F-FES PET scans combined with 18F-FDG PET scans in predicting response and patient stratification, and identification of genetic changes in cf-DNA and tumour biopsies potentially predicting response to Fulvestrant. [9] ProceduresSixty-minute dynamic [18F] FDG PET scans were performed in adult male C57BL/6 mice anesthetized with isoflurane [control (in 100 % O2), in medical air, in 100 % O2 + insulin pre-treatment, and in 100 % O2 after 18 h fasting], ketamine/xylazine, sevoflurane, and chloral hydrate. [10] COMPARISON WITH EXISTING METHOD Metabolic changes in 18F-FDG PET scans have a wider time span than abnormalities on EMG after denervation and it is correlated with the severity of nerve injury assessed by NCS. [11] To conclude, shape and intensity features were robust when comparing two types of [18F]-FDG PET scans (PET/CT and PET/MR). [12] METHODS Forty-two patients who were diagnosed as having HL and underwent pretreatment F-FDG PET scans were retrospectively enrolled. [13] MCI-HR-AD were recruited using Petersen criteria, neuropsychology (NPS), and 18F-FDG PET scans to confirm the high risk of progression to dementia with one year of follow-up. [14] PURPOSE The purpose of this work was to assess the potential of deep convolutional neural networks in automated measurement of cerebellum tracer uptake in FDG PET scans. [15] Methods: 18F-FDG PET scans of 544 MCI patients were obtained from the Alzheimer Disease Neuroimaging Initiative database and analyzed. [16] Subjects with a neurodegenerative disease and eFBP and FDG PET scans were retrospectively selected. [17] This perspective summarizes previous associations of changes in primary breast cancer tumor Ki and SUV with patient outcome from serial 18F-FDG PET scans and describes the development of Ki estimation methods designed to ease the clinical burden of acquiring the data required for traditional Ki analysis methods. [18] MethodsFluorescence in situ hybridisation analysis for MYC rearrangements, visual assesment, semiquantitative analysis of 18F-FDG PET scans and patient survival analysis were performed in 61 DLBCL patients, treated at a single referral hospital between 2008 and 2015. [19]当在 MRI 上确认肿瘤生长时，连续三天进行 2-[18F]FELP、[18F]FET 和 [18F]FDG PET 扫描。 [1] 我们提出了一个两阶段的深度学习框架，通过在 [18F] FDG PET 扫描中识别低代谢的候选区域来支持对局灶性癫痫患者的临床评估。 [2] 所有分析均在 67 次 [18F]FDG PET 扫描上进行，动脉血数据可用于比较。 [3] 方法纳入49例癌症患者和48例正常对照的18F-FDG PET扫描。 [4] 在“双重 PET”研究中，研究了在 AD 和其他痴呆症中的 PiB 和 FDG PET 扫描。 [5] 各种成像方式，包括 MRI、CT 血管造影和 FDG PET 扫描，都与 LVV 的诊断有关。 [6] 这突出了在随访 NSCLC 患者时仔细标准化用于连续 18F-FDG PET 扫描的 β 值的重要性。 [7] 目前，FDG PET 扫描的定量分析仅限于简单的指标，如最大标准化摄取值、代谢肿瘤体积或总病灶糖酵解，其预测价值有限。 [8] 探索性终点是连续 18F-FES PET 扫描用于评估治疗期间 ER 表达和功能状态的可行性，18F-FES PET 扫描与 18F-FDG PET 扫描相结合在预测反应和患者分层方面的价值，以及 cf 基因变化的识别-DNA 和肿瘤活检可能预测对氟维司群的反应。 [9] 程序对用异氟醚[对照（100% O2）、医用空气、100% O2 + 胰岛素预处理和 100% O2 麻醉的成年雄性 C57BL/6 小鼠进行 60 分钟动态 [18F] FDG PET 扫描禁食 18 小时后]、氯胺酮/甲苯噻嗪、七氟醚和水合氯醛。 [10] 与现有方法的比较 18F-FDG PET 扫描中的代谢变化比去神经后肌电图异常具有更宽的时间跨度，并且与 NCS 评估的神经损伤严重程度相关。 [11] 总之，在比较两种类型的 [18F]-FDG PET 扫描（PET/CT 和 PET/MR）时，形状和强度特征是稳健的。 [12] 方法 回顾性招募了 42 名被诊断为患有 HL 并接受了预处理 F-FDG PET 扫描的患者。 [13] 使用彼得森标准、神经心理学 (NPS) 和 18F-FDG PET 扫描招募 MCI-HR-AD，以确认在随访一年后进展为痴呆的高风险。 [14] 目的 这项工作的目的是评估深度卷积神经网络在自动测量 FDG PET 扫描中小脑示踪剂摄取方面的潜力。 [15] 方法：从阿尔茨海默病神经影像学倡议数据库中获得 544 名 MCI 患者的 18F-FDG PET 扫描并进行分析。 [16] 回顾性选择患有神经退行性疾病和 eFBP 和 FDG PET 扫描的受试者。 [17] 该观点总结了原发性乳腺癌肿瘤 Ki 和 SUV 变化与系列 18F-FDG PET 扫描患者结果的先前关联，并描述了 Ki 估计方法的开发，旨在减轻获取传统 Ki 分析方法所需数据的临床负担。 [18] 方法对 2008 年至 2015 年间在单一转诊医院接受治疗的 61 名 DLBCL 患者进行 MYC 重排的荧光原位杂交分析、视觉评估、18F-FDG PET 扫描的半定量分析和患者生存分析。 [19]
