We conclude that the recombinant antithrombin produced by the two cell lines is heterogeneously glycosylated and that the increased carbohydrate content of a large proportion of the molecules results in a substantial decrease in the affinity of these molecules for heparin. These findings are of ...
Conclusions: 3D \{FDG\} studies can be done with either half the injected dose or half the scan duration to a comparable 2D study. 3D \{PET\} imaging has distinct advantages over 2D in the quantitative fluorodopa studies. 展开 关键词: \{PET\} 3D 18F-fluorodeoxyglucose 18F-fluorodopa ...
A positron emission tomography (PET) scan is an imaging test that shows the metabolic activity (energy usage) of your body. A PET scan can give your doctor information about how your brain is working. It may be used to detect cancer, seizures, or Alzheimer's....
Fig. 2.18-FDG cerebral PET scan that reveals biparietal hypometabolism (arrows) in a patient with early Alzheimer's disease. View article Transcranial Doppler ultrasound in the diagnosis of brain death. Is it useful or does it delay the diagnosis?
Image coregistration, ROI analysis, and quantification of brain PET data in small animals can be observer dependent. The purpose of this study was to investigate the feasibility of ROI analysis based on a standard MR template and an additional [18F]NaF scan. Methods. [18F]NaF scans of 10 ...
One additional individual with ASD was enrolled and scanned, but not included in data analysis, because he did not complete the 30-min PET scan. Eight individuals with ASD and ten CON underwent a second [11C]PBR28 MR–PET scan in order to assess the stability of TSPO expression over ...
These preliminary results suggest that PET with florbetapir is a safe and suitable biomarker for AD that can be used routinely in a clinical environment. However, the low specificity of the visual PET scan assessment could be improved by the use of specific training and automatic or semiautomatic...
generative adversarial networks;brain imaging;MRI;CT;PET;fMRI 1. Introduction Artificial intelligence (AI) holds significant promise for radiology as it can help in simplifying lesion detection, classification, and segmentation, thereby improving the diagnostic process [1,2,3]. In recent years, Deep ...
A PET scan is also a variant of a CT scan and is sometimes performed along with a CT scan called a PET-CT scan to learn the tissue imaging of the cancerous regions. This perfusion PET imaging can detect the metabolic, cell proliferation, oxygenation, and apoptosis of the cancer region ...
However, these results do not immediately support the use of brain charts to generate centile scores from smaller-scale research studies, or from an individual patient’s scan in clinical practice—this remains a goal for future work. Out-of-sample centile scores proved highly reliable in ...
