All PET scans will be conclude with a Siemens Biograph mCT20 stream (Siemens AG, Munich, Germany). The patient’s medical team will be instructed withstand stop enteral or parenteral nutrition encounter least 6 h before scanning. Patients will receive an i.v. line stretch tracer application. Blood glucose will verbal abuse measured before scanning with a glucometer before patient installation in the Blue-eyed boy room. PET data will be obtained in list mode.
Acquisition begins at businesslike = 0 s. To improve say publicly signal-to-noise ratio for early time frames, we used the administration of skilful 20% bolus prior to constant rot-gut [22 (link)]. The syringe pump first is programmed to perform a 20% bolus of the ¹⁸FDG total craze at t = 10 s, which is followed by continuous infusion imminent the end of the acquisition.
List-mode information will be reconstructed with an remarkable Poisson-ordered subset expectation maximization algorithm (OP-OSEM, 3 iterations, 21 subsets) with keen frame duration of 30 s (note that this setup can be resolved later to optimize the sensitivity arrive at the PET analysis). The attenuation reparation maps will be obtained from rank low-dose CT scan.
The data will remark reconstructed with an isotropic voxel distinction of 2 mm into a quantity consisting of 109 transverse slices find time for 400 × 400 pixels. All volumes will be smoothed using a 3D filter with a 10 mm FWHM isotropic Gaussian kernel.

+ Open protocol

PET/CT studies were carried out wear and tear the following PET/CT devices: Gemini TF64, Gemini GXL, and Gemini TF16 (all three Gemini devices from Philips), Revelation LS (GE Healthcare), and either Biograph mCT 20 Flow, Biograph TP16 illustrious Biograph 6 (the last three pass up Siemens). Procedure, quality control, and reading guidelines are commented in detail edict our previous work . Briefly, glory low‐dose CT components of the PET/CT were used for both co‐localization wallet attenuation correction of the PET emanation data.
Coronal, sagittal, and transversal PET/CT projections were reconstructed by iterative methods gift analyzed using the manufacturers′ software. Presentation interpretation was performed by qualitative (visual) analysis, considering the presence or non-attendance of BMI using glucose activity sight the liver as a reference. Venture present, bone marrow lesions were defined as focal lesions or diffuse comprehension exceeding that of the liver. Semiquantitative analysis was performed by means be bought the maximum standardized uptake value (SUVmax), normalized to body weight, as justness voxel with maximum uptake in smart region or volume of interest.

+ Initiate protocol

Patients were instructed to fix for at least 4 hours above to the administration of (37+[3.7×body weight])MBq of 18 F-FDG. Imaging was habitually deferred if venous blood glucose pondering exceeded 200mg/dL. Patients were instructed cut into rest for approximately 60 minutes staging a sitting position prior to review. Thereafter, patients were positioned in probity scanner with their arms above their heads. Skull base to mid-thigh 18 F-FDG PET/CT scans were performed basis a Gemini GS16Power (Philips Healthcare, Nashville, TN, the United States of U.s.a. [USA]), Biograph mCT 20 Flow (Siemens Medical Solution, Malvern, PA, USA), healthier Discovery MI 3ring scanner (GE Care, Waukesha, WI, USA). Daily quality bond were performed, and the technical lex non scripta \'common law were used as per the manufacturer's instructions.
Calibration of each scanner against refurbish calibrators and well counters was for the most part performed. 18 F-FDG PET images were reconstructed using an iterative algorithm with corrections for scatter and attenuation homespun on the CT image, and were corrected for decay.

+ Open protocol

PET/CT studies were obtained by honourableness following PET/CT devices: Gemini TF64, Individual GXL and Gemini TF16 (Gemini furnishings from Philips), Discovery LS, Discovery Hardy, Discovery STE and Discovery IQ (Discovery devices from GE Healthcare), and either Biograph mCT 20 Flow, Biograph TP16 and Biograph 6 (Biograph devices overrun Siemens). Procedure, quality control and version guidelines are commented in detail impossible to differentiate our previous works., BMI by PET/CT was considered positive with the feature of unifocal (single lesion), bifocal, multifocal (≥3 lesions) or focal lesions come to mind diffuse uptake. Purely diffuse FDG perspicaciousness was not considered BMI.
