Objective In this study, we aimed to evaluate the diagnostic sensitivities of 68 Ga-FAPI-04 PET/CT and 18 F-FDG in primary tumor, nodal, peritoneal distant organ metastases recurrent gastric adenocarcinoma (GAc) with patient lesion-based comparison. Materials method Twenty-one patients histopathologically proven newly diagnosed or GAc who underwent imaging were included study. Both techniques evaluated visually according intensity organ-based uptake. SUVmax tumor-to-background ratio (TBR)...
68Ga-fibroblast activation protein-specific inhibitor (FAPI)-04 PET/CT was performed in a 49-year-old woman diagnosed with breast cancer. In imaging, intense 68Ga-FAPI uptake observed the primary tumor, axillary lymph nodes, and also thyroid gland, whereas pathological 18F-FDG not gland. On ultrasonography, parenchyma heterogeneous, an area of focal thyroiditis superior part right lobe. Biochemical parameters were found to be consistent thyroiditis. This case shows that FAPI gland may...

68Ga-FAPI (fibroblast activation protein-specific inhibitor) PET/CT was performed in a 56-year-old man with multiple liver masses, which were confirmed grade 2 well-differentiated neuroendocrine tumors Tru-Cut biopsy. With 68Ga-DOTATE PET/CT, primary tumor the pancreas, metastases and metastatic portocaval lymph node detected. In imaging for comparison, it seen that lesions distinguished much better because of low background activity, clearly selected. This case suggested FAPI-bounded...
Abstract 68 Ga-fibroblast activation protein-specific inhibitor (FAPI)-04 PET/CT was performed in a patient with left lower outer quadrant breast cancer who had 18 F-FDG imaging. Ga-FAPI-04 showed higher accumulation of radiotracer primary tumor and axillary lymph nodes than PET/CT. In addition, focal increased FAPI uptake observed another nodular lesion the inner same breast, which considered malignant. However, Tru-Cut biopsy this reported as benign lymphoid tissue. This case that all...
Objective. The aim of this study is to investigate the uptake 68Ga-FAPI-04 in normal tissues and calculate standardized values (SUVs) for various organs body. Methods. A total 49 patients who underwent PET/CT were included our study. following identified on CT images: brain, parotid, submandibular glands, palatine tonsils, thyroid, lymph nodes (if present), breasts, lungs, thymus, left ventricle walls, mediastinal blood pool, vertebral bone marrow, liver, spleen, pancreas, stomach, small...
Objectives: This study aimed to compare the metabolic parameters obtained from 18 fluorine-fluorodeoxyglucose ( F-FDG) positron emission tomography/computed tomography (PET/CT) and gallium-68 68 Ga)-prostate-specific membrane antigen (PSMA) PET/CT investigate relationship between serum alpha-fetoprotein PET scan in patients with hepatocellular carcinoma.Methods: Fourteen were recruited after dynamic magnetic resonance imaging (MRI) of upper abdomen, F-FDG Ga-PSMA studies conducted.Regions...
Abstract An 83-year-old man presented with abdominal pain, vomiting, and bloating. His CT revealed heterogeneous peritoneal thickening in the lower quadrants, which was more prominent pelvic region. 18 F-FDG PET/CT performed to locate primary tumor showed irregular omental low moderate FDG uptake. 68 Ga–FAPI (fibroblast activation protein–specific inhibitor)–04 of patient, whose could not be detected using FDG, high radiopharmaceutical uptake areas on serosal surfaces. Peritoneal Tru-Cut...
AIM: The aim of this study is to evaluate the diagnostic value PET-CT scan for prediction EGFR mutation status and contribution TTF-1 expression scan. METHODS: We retrospectively studied 218 cases with a diagnosis pulmonary adenocarcinoma between 2012-2014 which underw ent analysis, before treatment. RESULTS: was present in 28.9% (n= 63) cases. positivity 66.9% 105). Standardized uptake (SUV max) 16.7 ± 6.8 mutant type, 13.8 7.6 having no mutations. According our evaluations, high SUVmax...
We aimed to examine the effect of a history COVID-19 on myocardial ischemia in single-photon emission computed tomography (SPECT) perfusion imaging (MPI) patients who presented with shortness breath and/or chest pain after recovery. For this single-center retrospective study, at cardiology outpatient clinics and had SPECT-MPI were screened. A total 1888 included 340 whom COVID-19. 64 > 50% stenosis coronary angiography excluded from study. The primary outcome study was abnormal MPI. In...
In this study, we aimed to compare the role of 68 Ga-labeled FAP inhibitor ( Ga-FAPI)-04 PET/computed tomography (CT) and 18 F-fluorodeoxyglucose F-FDG) PET/CT in evaluation primary tumor metastases patients diagnosed with malignant mesothelioma.Our prospective study included 21 histopathological diagnosis mesothelioma who underwent both Ga-FAPI-04 F-FDG imaging between April 2022 September 2022. Maximum standardized uptake value (SUVmax), metabolic volume, total lesion glycolysis,...
This study aimed to determine whether intravenous contrast-enhanced dual-phase fluorine-18--fluorodeoxyglucose (F-FDG) PET/CT scans provide additional diagnostic information compared with the MRI/CT in patients laryngeal carcinoma during initial staging.Forty-five consecutive (44 men, one woman; mean age±SD, 67.0±9.0 years, range: 45-80 years) of larynx who had and were enrolled. Each patient was scanned on system 1 h (early) 2 (delayed) after injection. The maximum standardized uptake...

Objectives: Several studies demonstrate the relationship between coronary artery disease and inflammatory parameters.Nevertheless, there is paucity of data regarding role high sensitivity (hs)-C-reactive protein (CRP) to albumin ratio (CAR) in patients with ischemia on gated single photon emission tomography (SPECT) myocardial perfusion imaging (MPI).This study was aimed at demonstrating CAR occurrence SPECT MPI.Methods: We retrospectively evaluated 2.048 referred for MPI from a cardiology...
Background Thrombolysis in Myocardial Infarction Frame Count (TFC) is an index that provides a quantitative evaluation of coronary microvascular dysfunction. In this study, we aimed to examine the effect COVID-19 infection on TFC patients admitted with chest pain and dyspnoea after disease had abnormal findings myocardial perfusion scintigraphy.Methods For single-center retrospective without history who were underwent angiography for scintigraphy between January 1, 2021 June 30, analysed....
