PET/CT Imaging Protocol for [18F]HX4

Check if the same lab product or an alternative is used in the 5 most similar protocols
[18F]HX4 PET/CT scans were performed using a high-resolution full-ring PET/CT scanners, including a GE Discovery, GE Discovery LS, Philips Gemini, and a Siemens Biograph PET/CT scanner. Images were reconstructed using scanner-specific parameters in accordance with each facility’s standard procedure, including at least attenuation and scatter correction. Repeat scans were performed on the same PET/CT scanner using the same protocol and patient positioning without respiratory gating.

Phantom Imaging for PET Attenuation Correction

Check if the same lab product or an alternative is used in the 5 most similar protocols
A 20-cm cylinder (Figure 3B) was filled with the same epoxy used in the IQ phantom, but without the addition of any radionuclide. This phantom was scanned on a General Electric Discovery LS and a Siemens HR+. Both scanners used positron sources to measure photon absorption at the same energy measured in clinical PET scans, 511 keV. Filtered backprojection was used to generate attenuation images. The phantom was also CT-scanned on the General Electric Discovery STE scanner, and attenuation images resulting from 80-, 100-, 120-, and 140-kVp CT scans were copied from the scanner console and read in MATLAB (MathWorks, Natick, MA).

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.
