Two sets of anthropomorphic phantoms were scanned using a second generation dual source CT scanner (SOMATOM Definition Flash, Siemens Healthcare, Forchheim, Germany). For both phantoms, DECT data were acquired using a DE default scan protocol at 80 kV/Sn140 kV, 200/95 effective mAs. Other settings were: gantry rotation time, 0.5 s; pitch, 0.6 and collimation, 32 mm × 0.6 mm. All DECT raw data were reconstructed with a dedicated dual‐energy filtered back projection medium‐soft convolution kernel (D30f). DECT image series were exported as axial images with a slice thickness of 1.5 mm and an increment of 1 mm. Finally, VMIs from 40 to 150 keV in 10 keV intervals were reconstructed with a dedicated application (Monoenergetic Application Class) and software on a multimodality workstation (Syngo MMWP VE 40A, Siemens Healthcare, Forchheim, Germany).

DSC-PWI images were acquired with an echo-planar imaging sequence using the following parameters: TR: 1640 ms; TE: 30 ms; slice thickness: 4 mm; number of slices: 24; FOV read: 220 mm; matrix: 128 × 128; flip angle: 90°; number of acquisitions: 60; scanning time: 1 minute 45 seconds; and a gadolinium contrast medium (Gd-DTPA, Magnevist, Beijing BeiLu Pharmaceutical Co, Ltd, Beijing, China) was intravenously injected using a high-pressure injector (Medrad Spectris Solaris EP MR injection system, Bayer HealthCare, Whippany, NJ) at the third acquisition (0.2 mL/kg, 4.5–5 mL/s, and followed immediately by a 30 mL physiological saline flush). All original data and images were sent to a Siemens Syngo MMWP VE40A postprocessing workstation and were analyzed with the MR Perfusion software. Maps of CBF, CBV, TTP, and MTT were generated using the local AIF mode.

Imaging was performed using dual-source CT scanner (Definition Flash; Siemens Healthcare, Forchheim, Germany; 280-ms rotation, 2_128_0.6 mm collimation) in deep inspiration. The scan begins with a scout imaging of the entire chest and abdomen, to define the view fields of coronary calcium and then for VAT acquisitions. The former acquired by prospective electrocardiogram-triggering scan with (3 mm slice thickness tube current 35 mA) then the raw data Reconstruction using Multi-Modality Workplace (SyngoMMWP VE40A, Siemens Medical Solutions, Forchheim, Germany) and calcium score software (VE40A) to calculate coronary calcium using Agatston method.

After scanning, all of the original data were transferred to the workstation (Syngo MMWP VE40A, Siemens Medical Solutions, Berlin and Munchen, Germany). The virtual non-enhanced (VNE) images and iodine-enhanced images were made using the liver Virtual Non-Contrast (Liver VNC) application mode of dedicated dual-energy postprocessing software (Syngo Dual Energy; Siemens Medical Solutions, Berlin and Munchen, Germany). This software provides an iodine overlay image that illustrates the iodine distribution in each individual CT voxel, representing the IRA and IC [24 (link)], which were generated for evaluation. The iodine-enhanced images were superimposed onto virtual non-enhanced images to combine the iodine distribution with anatomical information.

MDCTV were performed using a 128-slice, dual-source CT system (SOMATOM Definition Flash, Siemens, Germany). The thickness of the reconstruction slice was set at 1 mm, and the spiral pitch was set at 0.85 mm. In total, 400 ml of saline-diluted contrast agent (37% iodine, iopromide, Ultravist, Bayer; the dilution ratio was 1:9) was intravenously administered in a bolus through bilateral dorsalis pedis veins at the same flow rate of 1–1.5 ml/s. Real-time bolus tracking was carried out at inferior vena cava (IVC) and used to synchronize the contrast passage with the venographic data acquisition. The trigger threshold was 100 HU, and scanning was delayed 5 s after triggering. The scan extended from the ankle to the diaphragm. The raw data were uploaded to a workstation (SIEMENS Healthcare, syngoMMWP VE40A) for image reconstruction.

All patients fasted for at least 6 h. Blood glucose concentration was confirmed to be <7.1 mM in each patient prior to administering 18F-FDG. 18F-FDG was purchased from Tianjin Atom High Science Isotopes Medicine Co., Ltd. The radiochemical purity of 18F-FDG was 98%, which was tested by the manufacturer. At 1 h post-intravenous injection of 18F-FDG [5.55 MBq/kg (0.15 mCi/kg)], whole-body PET/CT examination was performed using a Biograph mCT 64 system (Siemens Healthineers) in the supine position. CT images were acquired from the skull base to the upper thigh area for attenuation map and lesion localization (94–140 mAs, 120 kVp, 5-mm wide section). A 3.0-mm thick section was reconstructed for attenuation correction followed by subsequent image fusion. PET images of the same area were acquired following CT scans in 3-dimensional mode, with 6–7 bed positions. Images were reconstructed using an iterative algorithm and were transported to a dedicated workstation (syngoMMWP VE40A; Siemens Healthineers) and analyzed using the syngo TrueD software (TRUED_SYSLATEST_VE10A40; Siemens Healthineers).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
