The radiological images used in the study were obtained from supine CT images with a slice thickness of 2.0 mm by using a 16-slice MDCT device (Aquilion 16; Toshiba Medical Systems, Tokyo, Japan). Imaging protocol values were as tube voltage: 120 kV, gantry rotation time: 0.75 seconds and pitch: 1.0 mm.

Liver CT Imaging Protocol

CT studies were performed using a 4-, 16-, or 64-detector row CT scanner (Light Speed QX/I, LightSpeed Ultra, LightSpeed VCT, GE Medical Systems, Milwaukee, WI, USA) or a 16-detector row CT scanner (Aquilion 16, Toshiba Medical Systems Corp., Tochigi, Japan). The same clinical protocol was used: 120 kV, 180–280 mAs depending on body habitus, a matrix of 512, and a field of view of 350–400 mm. Non-contrast CT was performed using a 5-mm contiguous axial section to encompass the whole liver. Non-contrast CT was mostly performed as part of the contrast-enhanced study.

Before the lumbar surgery, the survey of compressive lesions at the cervical and thoracic level in lumbar degenerative disease was performed. Patients were placed in the prone position, with the neck in neutral position. After myelography, CT scans were obtained using a multislice scanner (Toshiba Aquilion 16, Toshiba Medical, Tochigi, Japan). Image data were obtained in 0.5-mm slices, from the level of the occiput to the sacrum.

Preoperatively, Aquilion 16 and Aquilion 64 (Toshiba Medical, Tokyo, Japan) were used to collect all noncontrast 3D CT images in the craniocaudal direction under the following conditions: X-ray tube voltage, 120 kVp; automatic tube current modulation, maximum of 500 mA; gantry rotation speed, 0.5 sec; and beam collimation, 1 mm or 0.5 mm. Using a high-spatial-frequency technique (FC 86 or FC52; Toshiba Medical), whole lung axial thin-section multidetector CT scans were reconstructed at the same increment with a section thickness of 1 or 0.5 mm.

The AF area was determined by a computed tomography scan (either an Aquilion™ 16 [Toshiba, Tokyo, Japan] or Somatom® AR.C [Siemens AG, Erlangen, Germany]) in which TAFA, visceral AF area (VAFA), and subcutaneous AF area (SAFA) were measured at the level of the umbilicus. Outcomes were calculated using a computer software program (FatScan; East Japan Institute of Technology Co., Ltd., Osaka, Japan). The intraclass correlations for repeated determinations in our laboratory were 0.99.

All patients gave informed consent prior to treatment. Percutaneous RFA was performed using ultrasound and/or CT guidance. In the European center, procedures were performed under general anesthesia. Local anesthesia and conscious sedation with midazolam and fentanyl were used in the Asian center.
Both centers used similar RFA equipment: either a single electrode was used (3-cm-exposed tip Cooltip (Covidien, Gosport Hamspire, UK) or multiple electrodes with a switch-control system (3- or 4-cm-exposed tip Cooltip). Ablation was performed for 12 (single Cooltip electrode) or 16–20 min (multiple Cooltip electrodes) using standard impedance controlled ablation. In the European center, CECT was performed immediately after ablation on a spiral CT (Aquilion 16, Toshiba, Tokyo, Japan). If this CT showed residual tumor enhancement, immediate re-ablation was performed. In the Asian center, CECT was performed 1 day after ablation (Aquillion 64, Toshiba, Tokyo, Japan). If the CECT showed residual tumor enhancement, re-ablation was performed during the same or subsequent admission, dependent on the patient’s preference.

Cardiac CT Angiography Protocol with Landiolol

CCTA was performed between 4 and 7 min after completion of study drug administration. The reason for this timing of CCTA is that heart rate was reported to be the lowest between 4 and 7 min after intravenous administration of landiolol hydrochloride [8 ]. The CT equipment used were SOMATOM Sensation 16 (Siemens), SOMATOM Sensation Cardiac 16 (Siemens), Aquilion® 16 (Toshiba Medical Systems Co.), LightSpeed Ultra 16 (GE Medical Systems, Inc.), and LightSpeed Pro 16 (GE Medical Systems, Inc.). Table 1 shows the imaging conditions for each type of CT equipment. The rotation speed of the X-ray tube was set to the maximum for each type of equipment. Iopamidol (370 mgI/mL), a non-ionic contrast medium, was rapidly injected intravenously at 3–4.5 mL/s using a 2-channel injector followed by infusion of 20–30 mL saline.

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.
