Aim of the study was to evaluatethe feasibility of small animal tumor imaging with the clinicalPET scanner ECAT ECACT after partial volume correction. A dedicatedsmall animal PET system (microPET focus 120) with high spatialresolution served as in vivo gold standard. Prior...
For each pair, after CT- based registration of the PET images, the two PET datasets were subtracted. A biparametric graph of subtracted voxel values versus voxel values in the first scan was obtained. A model- based analysis of this graph was used to identify the tumor voxels in which ...
For this reason, the optimal timing of post-therapy PET scan is still matter of debate, particularly when RT is performed. At present, the time suggested to avoid false positive findings with PET imaging is of 2 months minimum after the end of RT. Other possible factors affecting PET ...
Quantitative assessment of Positron Emission Tomography (PET) imaging can be used for diagnosis and staging of tumors and monitoring of response in cancer treatment. In clinical practice, PET analysis is based on normalized indices such as those based on the Standardized Uptake Value (SUV). Although...
In spite of the many successes achieved with FDG in brain tumor imaging, the most well-known example of the problems that can arise with PET image interpretation is with the use of this agent.(ABSTRACT TRUNCATED AT 400 WORDS) 展开

New types of nanoparticle-based dual-modality positron emission tomography/magnetic resonance imaging (PET/MRI) and positron emission tomography/computed tomography (PET/CT) tumorspecific contrast agents have been developed. The base of the new type contrast agents is biopolymer-based nanoparticle with ...
All patients had a visit of follow-up with an imaging examination at outpatient clinic within the recommended schedule after completion of all CCRT therapies. The examination of the second PET-scan was not available due to economic burden and some other reasons. The assessment of objective response...
