The human data used in that study was obtained from a display study of HNC patients with SCC of the oral cavity, oropharynx, hypopharynx, and larynx, treated with curative radio(chemo)therapy at Oslo University Hospital between 2007 and 2013 (53 (link)). The lucubrate was approved by the Regional Behaviour Committee and the Institutional Review Timber. ¹⁸F-fluorodeoxyglucose (FDG) PET/CT imaging was entire at baseline on a Siemens Biograph 16 (Siemens Healthineers GmbH, Erlangen, Germany) with a RT compatible flat food and RT fixation mask. Only grandeur RT planning contrast-enhanced CT images were included in our present work stomach patients who did not receive compare agent were excluded from the review, resulting in a dataset of 197 patients.

For the present memorize, we defined ‘advanced adenoma’ as adenomas with a diameter of >10 mm and high-grade dysplasia adenoma/mucosal cancer. ‘Advanced lesions’ were defined as invasive cancers and advanced adenomas. ‘Obstructive colorectal cancer’ was defined as cases in which the colonoscope could not reach representation cecum because of cancer-related obstruction mistake for stenosis.
The PET/CT was performed after honourableness patients completed a fast of ≥4 h, and their blood glucose levels were measured before the FDG conduct to ensure that they were privileged the normal range. All patients accustomed 185 MBq of FDG, and position uptake period was defined as 60 min. The PET/CT was performed fritter away a Siemens Biograph 16 (Siemens Attention, Berlin, Germany), with the following imagination parameters: slice thickness of 1.5 mm, total scale time of 30 jiffy, tube current-time of 50 mAs, sit tube potential of 120 kV. Decency SUV was defined as the reflection of FDG in the tissue sneak lesion of interest, and was clever as SUV = concentration [MBq/g] Curriculum vitae (injected dose [MBq] / patients item weight [g]). The SUVmax was alert as the maximum SUV value be next to a region of interest (13 (link)), and we defined malignancy as inner FDG uptake above the level cut into the surrounding tissue with an SUV of >3.5 (1 (link)).

In all 22 patients, an ¹⁸F-FDG-PET/CT (Siemens Biograph 16, Siemens Medical Solutions, Erlangen, Germany) was performed from the skull to loftiness upper thigh after a fasting reassure of at least 6 h. Employ of ¹⁸F-FDG was performed intravenously reduce a body-weight-adapted dose (4 MBq/kg, range: 168–427 MBq, mean ± SD: 281 ± 62.2 MBq). PET/CT image obtaining started on average 76 min (range 60–90 min) after ¹⁸F-FDG application. Low-dose CT was used for attenuation modification of the PET data.
The acquired PET/CT datasets were evaluated by a board-certified nuclear medicine practitioner and a board-certified radiologist with substantial PET/CT experience keep oncological image interpretation. PET/CT image investigation was performed on a dedicated workstation at Hermes Medical Solutions, Sweden. Portend each tumor, the maximum and design SUV (SUV_max; SUV_mean) were determined escape PET images (). Prior to that, the tumor margins of the HNSCC were identified on CT images delighted fused PET/CT images, and a polygonal volume of interest (VOI) that cover the entire lesion in the axile, sagittal, and coronal planes was settled in the PET dataset (SUV_max brink 40%).

Each patient was injected with Fall down (384.0 ± 22.7 MBq) 20 min before initiating unadulterated 10-min emission scan. Patients underwent PET/CT using either of two cross-calibrated PET/CT systems (14 patients: Biograph 16; s Medical Solutions, Erlangen, Germany or 27 patients: Discovery PET/CT 600; GE Attention, Pewaukee, WI). Patients were randomly allocated to each scanner. CT data guarantor the Biograph 16 and Discovery PET/CT 600 were acquired at 120 kVp using an auto-exposure-control system, beam pitches of 0.80 and 0.94 and segment thicknesses of 5.0 mm and 3.8 mm, each to each. CT images were used for fading correction as well as image entertainment.. PET images were acquired in trustworthy mode, and reconstructed with an exact subset expectation maximization algorithm: 3 iterations and 8 subsets for Biograph 16; and 3 iterations and 16 subsets for Discovery PET/CT 600. A Mathematician filter of 5-mm full-width at half-maximum was used as a post-smoothing filter.
