CT was performed using the same scanner (BIOGRAPH 40; Siemens) at 120 kV and 220 mAs (CARE Dose4D). The slice thickness was 3 mm, and the interval was 2 mm. MRI was performed on a 3-T system (Achieva; Philips, Best, The Netherlands) using a 32-channel cardiac coil. MR images were obtained with T1-weighted, T2-weighted, and STIR sequences in the coronal and axial planes, and diffusion images were also obtained, all of which represent MARS-MRI.
Biograph 40
The Biograph 40 is a positron emission tomography (PET) scanner manufactured by Siemens. It is designed to acquire high-quality images of the human body for medical diagnostic purposes. The core function of the Biograph 40 is to detect and measure the distribution of radioactive tracer substances within the body, which can provide valuable information about the physiological and metabolic processes occurring in various organs and tissues.

Amyloid PET Imaging Protocol Using 18F-Florbetaben
All MRI images were normalized to a T1-weighted MRI template, and then each PET image was co-registered with each normalized MRI image. The automated anatomic labeling atlas18 (link) was used to obtain volume of interest (VOI) quantitative values. Standardized uptake value ratio (SUVR) is calculated as the degree of radiotracer uptake of a region of interest relative to a reference region and is the most common quantitative method used to calculate amyloid deposition levels in AD. We calculated SUVR using whole cerebellum as a reference region to determine the level of Aβ deposition in each VOI region.

PET-CT Imaging of [18F]HX4 Tracer Uptake
The images were reconstructed using scanner-specific parameters in accordance with each facility’s standard procedure, including at least attenuation and scatter correction.
The 4 h post-injection (p.i.) time point is related to a plateau phase in tracer uptake associated with optimal imaging properties [15] (link). More details regarding the acquisition parameters/protocol and scanner types are presented in

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.
