Pet Ct Scans(宠物 CT 扫描)研究综述
Pet Ct Scans 宠物 CT 扫描 - Methods: The diagnostic accuracy of a total of 97 patients with initial 18F-PET/CT scans between January 2015 and February 2020 were assessed, and the SUVmax was compared according to the different pathological subtypes. [1] Methods A total of 66 patients with histopathologically confirmed papillary RCC who underwent either staging or restaging FDG PET/CT scans (30 had staging scans only, 28 had restaging scans only, 8 had both) were retrospectively included in this study. [2] Methods Thirty-eight patients (24 males and 14 females) with primary CRC confirmed by elective surgery pathological, who also accepted 18 F-FDG PET/CT scans during 2017 to 2019 were included in this study. [3] All patients had standard of care18F-fluciclovine total-body PET/CT scans after a negative or equivocal cross-sectional conventional imaging. [4] Methods: All consecutive adult subjects undergoing PET/CT scans with any radiotracer at our center during the first month of a national COVID-19 vaccination rollout (between 23 December 2020 and January 27, 2021) were included. [5] List-mode data from 277 [18F]-FDG PET/CT scans, from six centres using GE Discovery PET/CT scanners, were split into ¾-, ½- and ¼-duration scans. [6] A total of 547 patients with primary prostate cancer and 443 lesion segments that underwent 68Ga-PSMA PET/CT scans were included and their pathological biopsies were compared. [7] A total of 199 colorectal cancer patients underwent pre-therapy diagnostic 18F-FDG PET/CT scans and CRC radical surgery. [8] Methods: Routine primary diagnostic 18F-FDG PET/CT scans of consecutive NSCLC patients were included. [9] During 18F-fluorodeoxyglucose (18F-FDG) PET/CT scans, the MTV and TLG were recorded. [10] Each subject underwent 2 68Ga-PSMA-11 PET/CT scans within 14 d under baseline and MSG conditions. [11] This communication describes an advanced functional virtual bronchoscopic (fVB) method based on the registration of PET images to high-resolution diagnostic CT images instead of low-dose CT images of lower resolution obtained from PET/CT scans. [12] Methods Eighteen healthy subjects underwent two dynamic 82 Rb PET/CT scans in two different fields of view (FOV). [13] All FDG-PET/CT scans performed in Imperial College NHS Foundation Trust, UK between January 2012 and November 2018 were included. [14] Patients and Methods: All PET/CT scans of patients admitted to our department for suspected ECS between 2010 and 2020 were retrospectively analysed. [15] Methods This prospective study was conducted in 24 healthy right-handed volunteers (13 men, 11 women; aged: 42-79 years) who underwent 18F-THK 5351 and 11C-PiB PET/CT scans. [16] 18 F-FDG PET/CT scans were performed before nCRT and 4–6 weeks after the completion of nCRT. [17] Materials and Methods: In this retrospective cohort study, we screened over 52′000 PET/CT scans to identify patients diagnosed with either soft tissue, bone or Ewing sarcoma and had a staging scan at our institution before initial therapy. [18] Evaluation of PET/CT scans using (semi-)quantitative measures such as SUVs should be performed with great caution, as SUVs are influenced by scanning and reconstruction parameters. [19] All 129 68Ga-FAPI PET/MR or PET/CT scans from June 1, 2020, to February 20, 2021, performed at our PET center were retrospectively reviewed. [20] RESEARCH QUESTION Do CAP survivors have evidence of increased inflammatory activity in their lung parenchyma on 18FDG-PET/CT after clinical resolution of infection? STUDY DESIGN and Methods: We performed 18FDG-PET/CT scans in 22 CAP-survivors during their hospitalization with pneumonia (acute-CAP) and 30-45 days after the hospital discharge (post-CAP). [21] TNM status was compared for staging and RT planning scans and the probability of TNM status and overall stage migration was analyzed as a function of the interval between PET/CT scans. [22] All 68Ga-PSMA PET/CT scans were centrally reviewed. [23] The short half-life of existing prostate-specific membrane antigen (PSMA) tracers limits their time for internalization into tumor cells after injection, which is an essential prerequisite for robust detection of tumor lesions with low PSMA expression on PET/CT scans. [24] Sixteen patients with suspected head and neck cancer underwent 2-deoxy-2-[18F]fluoro-d-glucose WB PET/CT scans, followed by fxPET and 3 T MRI scans. [25] 8) underwent two [ 18 F]FP-CIT PET/CT scans with an interval of 48 ± 7 day. [26] Three blinded central readers evaluated the 18F-DCFPyL-PET/CT scans. [27] The Eisenkop score, PCI score, and tumor volume of PET/CT scans were compared with surgical findings. [28] To the best of our knowledge, only 3 case reports have been published till date describing CPM on 18F-FDG PET/CT scans. [29] The patients received pre-, mid-, and end-treatment 18F-FDG PET/CT scans. [30] METHODS Retrospective analysis on 114 consecutive patients undergoing staging PSMA PET/CT scans over 12 months was carried out. [31] Data from 5 min dynamic PET/CT and conventional PET/CT scans were retrospectively collected from 17 pathologically diagnosed HCCs. [32] ConclusionsA starting activity of [18F]-Fluoride of 90 GBq (range B) enables a final amount of [18F]-PSMA-1007 of about 50 GBq, which is powerful for different choices: to perform up to 25 PET/CT scans in a referral institution for prostate cancer, and/or to supply the eventual peripheral PET centers. [33] MATERIAL AND METHODS 65 18F-FDG PET/CT scans of 41 patients with diagnosis of seminoma were analyzed and compared to alpha-fetoprotein (AFP) and human chorionic gonadotropin (hCG). [34] 3 on PET/CT scans performed with a high specific activity (median = 178. [35] Results A total of 81 68 Ga-DOTATATE PET/CT scans in 74 patients were found, and 11 patients were excluded from analysis as they had no prior imaging available for comparison, with resultant analysis cohort of 63 patients. [36] 68 Ga-PSMA-617 and 18 F-FDG PET/CT scans will be performedfirst. [37] Bilateral iliac bone marrow pathology and whole-body 18F-FDG PET/CT scans confirmed that the leukemic infiltration in her bone marrow was asymmetric. [38] Objective To evaluate the utility of the ROLL (Radioguided Occult Lesion Localization) technique as a method of excisional biopsy in hypermetabolic lesions suspected of malignancy evidenced in [18F]Fluordeoxiglucose PET/CT scans. [39] Methods A total of 173 patients that underwent 18F-FDG PET/CT scans before operations were retrospectively analyzed in this study. [40] All patients underwent PET/CT scans at baseline, 3 weeks after three cycles of treatment, and 6 weeks after all cycles of treatment. [41] We selected patients whose interval between MRI and FDG PET/CT scans was within 3 months, from January 2017 to December 2018, and classified them into mild, moderate, and severe groups by following the semiquantitative rating method of Fazekas. [42] Six studies (684 patients and 829 PET/CT scans) were included. [43] Ionising radiation-free whole-body MRI versus (18)F-fluorodeoxyglucose PET/CT scans for children and young adults with cancer: a prospective, non-randomised, single-centre study. [44] Modern radiation techniques should be used with involved-field radiotherapy based on baseline CT and PET/CT scans. [45] A total of 26 18F-FDG PET/CT scans were performed, and the initial and follow-up PET/CT imaging features, clinicopathologic and immunohistochemical characteristics, and outcome were analyzed. [46] Eighty-five patients with Stage III–IVB NPC underwent pretreatment [18F]FDG PET/CT scans and received radiotherapy or chemoradiotherapy. [47] Therefore, tau quantification is possible with [ 18 F]MK-6240 PET/CT scans, and it can be used for assessment of Alzheimer’s disease. [48] 05, which suggest the potential of findings from 68Ga-PSMA-PET/CT scans as well as patient-specific clinical parameters for the prediction of OS for patients with advanced PC treated with 177Lu-PSMA therapy. [49] PET/CT scans were interpreted using a 4-point score (0 = no uptake; 1 = cardiac uptake < blood-pool activity; 2 = blood-pool < uptake < liver activity; 3 = uptake > liver) and semi-quantitatively using SUVmax and SUVmean of the suspected valve lesion, liver, spleen, and of the bone marrow (BM).

standardized uptake value 标准化摄取值
Finally, PET/CT scans in three cancer patients revealed higher intratumoral uptake of 68Ga-DOTA-2P(FAPI)2 than that of 68Ga-FAPI-46 in all tumor lesions (maximum standardized uptake value: 8. [1] All of the patients underwent baseline 18F-FDG PET/CT scans, and the primary lesion SUVmax (maximum standardized uptake value), liver SUVmean (mean standardized uptake value), spleen SUVmean, TLR (Tumor-to-liver SUV ratio) and TSR (Tumor-to-spleen SUV ratio) were included in the study, combined with clinical examination indicators to evaluate DFS (disease free survival). [2]最后，3 名癌症患者的 PET/CT 扫描显示，在所有肿瘤病变中，68Ga-DOTA-2P(FAPI)2 的肿瘤内摄取高于 68Ga-FAPI-46（最大标准化摄取值：8.
