In contrast, PSF images reconstructed using the same PET raw data lead to higher, non-monotonic, and less reproducible RCs.
This study analyses the influence of methodological differences between two centres for tumour characterization with 18F-FET PET using the same PET scanner.
During radiotherapy, only a dedicated head and neck PET acquisition was performed with an accompanying contrast-enhanced CT component using the same PET and CT imaging parameters detailed above.
The reproducibility of the studies described above was assessed using the same PET schedule and two newly bred Tg mice 5 and 7 and age-matched controls 6 and 8. Base FDG uptake of mouse 5 was measured at 38 days of age and tumor-dependent increases in metabolic activity were determined on days 68, 104, 114 and 152 (Supplementary Figure 1).
Indeed, the 66%% improvement in SUVmax in this study can be compared with the 48%% improvement observed in a previous study dealing with thoracic lymph node staging in patients with non-small-cell lung cancer (NSCLC) that used the same PET system and acquisition/reconstruction parameters [ 8].
If there are ever two Scholars in your party, make sure that both of you do not use the same pet.
At 1 day after two irradiation treatments, these mice were imaged with 18F-FDG (11.1 ± 1.0 MBq) PET using the same protocol as the first PET scan.
A low-dose CT scan for attenuation correction was performed using the same scanner directly after PET; in addition where the administration of a contrast agent (Omnipaque 350, GE Healthcare, Milwaukee, USA) was not contraindicated (serum creatinine level >1.5 mg/dl or estimated glomerular filtration rate <60ml/min), a diagnostic carotid angiogram (CTA) was performed using bolus tracking.
The 4D-PET was reconstructed using the same reconstruction parameters as the WB-PET.
Using the NdeI and BamHI restriction sites (underlined in primer sequences), the putative TbC/EK1 was ligated into the expression vector pET-15b (Novagen) modified with a TEV (tobacco etch virus) protease cleavage site (in place of a thrombin cleavage site) using the same restriction sites generating the pET-15bTEV Tbconstructstruconstruct
