Cu-ATSM and FDG PET uptake and Cu-ATSM autoradiography in spontaneous canine tumors: comparison with pimonidazole hypoxia immunohistochemistry
Background: The aim of this study was to compare Cu-diacetyl-bis(N-methylsemicarbazone) (Cu-ATSM) and FDG PET uptake characteristics and Cu-ATSM autoradiography to pimonidazole immunohistochemistry in spontaneous canine sarcomas and carcinomas. Methods: Biopsies were collected from individual tumors between approximately 3 and 25 hours after the intravenous injection of Cu-ATSM and pimonidazole...
متن کاملFDG-PET/CT based response-adapted treatment
It has been shown that [(18)F]fluorodeoxyglucose (FDG)-positron emission tomography (PET) provides robust and reproducible data for early metabolic response assessment in various malignancies. This led to the initiation of several prospective multicenter trials in malignant lymphoma and adenocarcinoma of the esophagogastric junction, in order to investigate whether the use of PET-guided treatme...
متن کاملSingle-scan dual-tracer FLT+FDG PET tumor characterization.
Rapid multi-tracer PET aims to image two or more tracers in a single scan, simultaneously characterizing multiple aspects of physiology and function without the need for repeat imaging visits. Using dynamic imaging with staggered injections, constraints on the kinetic behavior of each tracer are applied to recover individual-tracer measures from the multi-tracer PET signal. The ability to rapid...
متن کاملExploratory analysis of using supervised machine learning in [18F] FDG PET/CT images to predict treatment response in patients with metastatic and recurrent Brest tumors
Aim: Despite grate progress in treatments, breast cancer is still the most common invasive cancer and the most cause of cancer related death in women. Treatment could be improved and perhaps standardized if more reliable markers for tumour progression and poor prognosis could be developed. The aim of this study was to evaluate whether patient-based machine learning (ML) driven ...
متن کامل[18F]FLT-PET and [18F]FDG-PET in the evaluation of radiotherapy for laryngeal cancer.
The evaluation of response to radiotherapy in patients with laryngeal cancer is a challenge because of the difficulty to differentiate between post-therapy changes and recurrent or residual tumor. Positron emission tomography is a non-invasive imaging tool that may be helpful in this differentiation. In this study, [(18)F]-fluoro-3'-deoxy-L-thymidine ([(18)F]FLT), a proliferation tracer is comp...
