Breast-Dedicated PET/CT Acquisition Protocol

All ¹⁸F-FDG PET/CT acquisitions were performed on a Biograph TrueV (Siemens Healthineers) before any treatment. Patients were fasted during at least 6 h. A high-resolution (HR) breast-dedicated bed position (6 min per bed position) was acquired 75 min after the radiopharmaceutical injection. Data were reconstructed using an algorithm with point spread function (PSF) modeling (HD; TrueX, Siemens Healthineers, 3 iterations, and 21 subsets) with no post-filtering and a 512² matrix size leading to voxels of 1.3 × 1.3 × 1.9 mm (19 (link)).

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.
