Sensation 16 ct

Manufactured by Siemens

Sourced in Germany

The Sensation 16 CT is a computed tomography (CT) scanner manufactured by Siemens. It is a diagnostic imaging device that uses X-rays to create detailed, cross-sectional images of the body. The Sensation 16 CT has 16 detector rows, allowing for faster image acquisition and improved spatial resolution compared to earlier-generation CT scanners.

All imaging was conducted on a 16-section multidetector scanner (Sensation 16 CT; Siemens Medical Systems, Forchheim, Germany).
First NECT was performed from the skull base to the vertex using the following imaging parameters: 120 kVp, 285 mAs, collimation 0.75mm, FOV = 220mm, 4.5mm slice thickness, matrix 512x512, soft tissue kernel (H30s).
Subsequently, CT-perfusion (CTP) was performed for confirmation of diagnosis and therapy decision making, but the data was not further analysed in this study.
Additionally, a CT-angiography (CTA) covering the area from the carotid bifurcation to the vertex was performed. It was done as follows: 0.7 mL/kg contrast, 5- to 10s delay from injection to scanning using 120 kVp, 366 mAs, 0.75 mm collimation, 200 mm FOV, H20f kernel with 0.7 and 1mm reconstructed slice thicknesses and coronal and sagittal MPRs.

Patients underwent a contrast-enhanced CT scan using one of the following systems: LightSpeed VCT (GE Healthcare), Sensation 64 CT (Siemens), or Sensation 16 CT (Siemens). Three phases, including non-enhanced, arterial, and portal vein phase, were obtained. Arterial phase scanning started about 20−30 s after the beginning of injection, and portal phase scanning was started 30−40 s after the beginning of the arterial phase. The reconstitution thickness was set at 1−2 mm, and reconstructions were done on a GE Advantage Windows 3D workstation (GE Healthcare, Waukesha, WI, USA). The following parameters were used: tube voltage, 120 or 100 kVp; tube current, 150–600 mA; slice thickness, 1.25 mm; pitch, 1.375. All patients received an intravenous, nonionic contrast medium (iodine concentration, 370 mg/mL; volume, 1.5–2.0 mL/kg of body weight; contrast type, Iopromide Injection, Bayer Pharma AG) at a rate of 3–5 mL/s. A volume of 20 mL saline was injected after the injection of the contrast.

With the patient in the supine position, plain and two-phase (arterial and portal vein phases) iodinated contrast-enhanced computed tomography (CT) scans were obtained in a craniocaudal direction using either of two scanners, namely the Sensation 16 CT or Somatom Definition dual-source CT (Siemens Medical Solutions, Erlangen, Germany). Routine scanning was conducted at an 8-mm section thickness and a 5-mm scan increment; scans were reconstructed with a 2-mm thickness using an appropriate algorithm. A dual-syringe injector system (Medrad Medical Equipment Trading Co., Ltd., Beijing, China) was used to intravenously administer 100 ml non-ionic contrast media (Ultravist; 370 mgI/ml; Bayer AG, Leverkusen, Germany) at a rate of 3 ml/sec, followed by a 20–30-ml saline chaser bolus. Magnetic resonance imaging (MRI) scans were acquired using a Magnetom Trio 3.0T scanner (Siemens Medical Solutions). Routine scanning of transverse sections was performed with T2-weighted fast spin-echo sequences, two-dimensional gradient echo in the axial plane, and T2-weighted half-Fourier acquisition single-shot turbo spin echo without fat saturation. A three-dimensional gradient echo sequence (VIBE) with fat saturation was performed prior to and following the intravenous bolus administration of gadopentetate dimeglumine (Magnevist; Schering, Berlin, Germany) at a dose of 0.1 mmol/kg.

All patients underwent a multi-slice CT scan with four phases including unenhanced, arterial, portal venous, and delayed contrast-enhanced phase, using the following systems [LightSpeed VCT (GE Healthcare, Chicago, IL, USA), Sensation 64 CT (Siemens, Erlangen, Germany), or Sensation 16 CT (Siemens)] in West China Hospital. The scanning parameters were as follows: 100 or 120 kVp; tube current, 150–600 mA; slice thickness, 5 mm. After plain scanning was completed, a non-ionic contrast medium (iodine concentration, 370 mg/ml; volume, 1.5–2.0 ml/kg of body weight; contrast type, Iopromide injection, Bayer Pharma AG, Berlin, Germany) was injected at 3–5 ml/s through the antecubital vein, and 20 ml saline was injected after the injection of the contrast. Arterial phase, portal venous phase, and delayed phase scanning started at 30, 60, and 180 s after the contrast medium was injected.

The individuals under study underwent contrast-enhanced CT using one of the following systems: Sensation 64 CT (Siemens, Munich, Germany) or Sensation 16 CT (Siemens, Munich, Germany). Triple-phase CT examinations were conducted, including non-enhanced, arterial, and portal vein phases. The abdomen scouts were acquired from the dome of the diaphragm to the iliac crests. The arterial phase of the same region started at approximately 20–30 s after the administration of contrast agent, followed by the portal phase (30–40 s). Reconstructions were performed on a GE Advantage Windows 3D workstation (GE Healthcare, Waukesha, WI, USA) with the reconstitution thickness set at 1–2 mm.

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.
