All child patients underwent continuous volume cranial scanning using Philips Brilliance 16-slice spiral CT scanner ((Philips, Amsterdam, Holland). CT parameter settings are shown in Table I . Plain and enhancement scans were performed from diaphragmatic dome to the pubic symphysis of child patients with iohexol as the contrast agent. Original image data were sent to the ADW4.5 Workstation for multi-planar reconstruction (MPR), volume rendering (VR) and curved planar reconstruction (CPR). Tumor tissue sections of patients were fixed in 10% formaldehyde, followed by paraffin embedding, and hematoxylin and eosin staining. Immunohistochemical staining was also performed using neuron-specific enolase (NES), S-100 protein (S-100), synaptophysin (Syn) and chromogranin A (CgA). According to CT signs, NB calcification and invasion to surrounding tissues were evaluated by microscope (Olympus, Tokyo, Japan), and the tumor site, tumor size, lymphatic metastasis, pathological type and clinical prognosis were analyzed.
Brilliance 16 slice spiral ct scanner
Manufactured by Philips
The Philips Brilliance 16-slice spiral CT scanner is a medical imaging device that uses X-rays to create detailed cross-sectional images of the body. It is designed to capture high-quality images of the body's internal structures, providing healthcare professionals with critical information for diagnosis and treatment planning.

CT examination: a PHILIPS Brilliance 16-slice spiral CT scanner was used to scan patients in the supine position, and the scanning parameters were as follows: voltage 120 kV, current 90 mA, scanning slice thickness 3 mm, matrix 515 × 515, FOV 180 mm × 180 mm, and reconstruction interval 1.0-2.0 mm. After scanning, the original volume data were transferred to the workstation for multiplanar reconstruction (MPR), surface shaded display (SSD), volume rendering (VR), and other processing. MRI: scans were performed using a Kangda 1.5 T MR scanner. Patients were placed in the supine position, and the scanner was used to identify the cross-sectional spin echo (SE) pulse signal with the pulse sequence set as follows: T1WI (TE: 11 ms, TR: 540 ms); T2WI (TE: 80 ms, TR: 3200 ms); layer thickness 8-10 mm, layer spacing 1 mm, field of view 38 cm × 38 cm, and matrix 256 mm × 256 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.
