The 3-slice CNN model with a short-time scan of at least 2 minutes achieved comparable, quantitative prediction of full-time 18F-FBB PET/CT images, with adequate to excellent image quality. Conclusions: The 3-slice CNN model with a residual learning framework is promising for the prediction ...
Use of corrected standardized uptake value based on the lesion size on CT permits accurate characterization of lung nodules on FDG-PET. Eur J Nucl Med Mol Imaging. 2002;29(12):1639–47. Article PubMed Google Scholar Kessler RM, Ellis JR, Eden M. Analysis of emission tomographic scan data...
For attenuation correction, CT images were acquired using a 16-slice helical CT (140 keV, 80 mA; 3.75 mm section width). Ninety minutes after injecting 300 MBq ± 20% 18F-florbetaben, a 20-min emission PET scan in a dynamic mode (consisting of 4 × 5 min frames) was ...
amyloid-negative as well as amyloid-positive results had an important association with changes in diagnosis and treatment. Etiologic diagnosis changed for 25% of patients after amyloid PET, more often because of a negative than a positive PET scan result. In addition, PET scanning increased diagnost...
Recently, PET/CT room from the First Affiliated Hospital (FAH) of Xi’an Jiaotong University (XJTU) introduced a novel international PET tracer, becoming the first to perform PET/CT imaging for β-amyloid protein in northwest China, which provided potent technical support for prompt diagnosis and...
Three individuals refused a follow-up MRI scan. 18F-Flutemetamol PET 18F-Flutemetamol PET scans were acquired on a 16-slice Biograph PET/CT scanner (Siemens, Erlangen, Germany) at baseline and follow-up, with a net injected intravenous activity of 149 MBq (127–162 MBq) and 149 MBq (77–...
52). The CT scan was manually aligned with a T2-weighted, magnetic resonance imaging-based mouse brain atlas53 containing outlined regions of interests for hippocampus, striatum, thalamus, cortex and cerebellum. The PET image was then aligned with the CT, and thus, the magnetic resonance imaging...
Nonetheless, the possibility of correctly diagnosed DLB with a normal florbenazine PET scan cannot be entirely excluded. Absence of substantial nigra cell loss is observed in approximately 10% of DLB cases at autopsy [33]. An imaging study with autopsy follow-up found 7 clinical DLB cases with...
(range 259–550 MBq). CT scans were performed for attenuation correction 60 minutes after injection. A 30-minute emission static PET scan was then initiated. The specific radioactivity of [C-11] PiB at time of administration was more than 1,500 Ci/mmol for patients and the radio...
