Background: In selective internal radiation therapy, Tc SPECT images are used to optimize patient treatment planning, but they are affected by respiratory motion. In this study, we evaluated on patient data the dosimetric impact of motion-compensated SPECT reconstruction on several volumes of interest (VOI), on the tumor-to-normal liver (TN) ratio and on the activity to be injected.
Methods: Twenty-nine patients with liver cancer or hepatic metastases treated by radioembolization were included in this study.
Background: PET imaging of Y-microsphere distribution following radioembolisation is challenging due to the count-starved statistics from the low branching ratio of e/e pair production during Y decay. PET systems using silicon photo-multipliers have shown better Y image quality compared to conventional photo-multiplier tubes. The main goal of the present study was to evaluate reconstruction parameters for different phantom configurations and varying listmode acquisition lengths to improve quantitative accuracy in Y dosimetry, using digital photon counting PET/CT.

We aim to report discrepancies in ultrasound and F-FDG PET/CT results.
Methods: This single-centered retrospective analysis selected consecutive patients with invasive ductal biopsy-proven breast cancer, for whom divergent F-FDG PET/CT and axillary ultrasound imaging (and/or core needle biopsy if available) had been performed, and described clinical, histological, imaging, and surgery data.
