All 128 patients underwent a CT examination of the paranasal sinus before surgery. Philips Brilliance 64-layer spiral CT scanner was used for spiral scanning of sections of the paranasal sinus, with scanning parameters set as below: matrix of 512 × 512, collimation of 64 × 0.625, 0.75 seconds as the slew time of bulb tube, screw pitch of 0.64 mm, a voltage of 120 kV, and current of 300 mA. The images were reconstructed by bone algorithm, with the layer thickness as 0.17 mm, interlamellar spacing as 0.67 mm, image bone window width as 2000 HU and window level 200 HU.
Brilliance 64 layer spiral ct scanner
Manufactured by Philips
The Brilliance 64-layer spiral CT scanner is a diagnostic imaging device manufactured by Philips. It uses advanced spiral CT technology to capture high-resolution, three-dimensional images of the body's internal structures. The scanner's 64-layer design allows for rapid data acquisition and reconstruction, providing detailed anatomical information to healthcare professionals.

The chest was scanned using a Philips Brilliance 64-layer spiral CT scanner. The layer thickness was 1.25 mm, the tube current was 160 mAs, and the tube voltage was 120 kV. Iohexol, a contrast agent containing 300 mg/ml of iodine, was injected into the elbow vein during an enhancement scan at a dosage of 1.0-1.5 mL/kg at a rate of 3 mL/s with a latency of 25–30 s. After inspiration, the scan was held with the patient lying on his or her back with both hands on each side of the head. After inspiration from above the lung tip to below the diaphragm level, the patient was positioned in a supine posture with both hands on each side of the head. Images from the CT scan were exported in DICOM format.
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.
