- Abstract
Selective internal radiation therapy (SIRT) with yttrium-90 (90Y) is a potential treatment option for liver malignancies. Pre- and post-therapy imaging, such as single-photon emission computed tomography with computed tomography (SPECT/CT) and 90Y positron emission tomography (PET), play a crucial role in estimating absorbed radiation doses and assessing treatment efficacy. Whole-body PET/CT with long-axial-field of view (LAFOV) allows for comprehensive evaluation of absorbed dose to lung and healthy liver tissue. A recent study explored the feasibility of shorter scan durations while maintaining image quality, finding that 5-minute scans produced comparable results to 20-minute scans. Further research is needed to validate these findings and establish the broader applicability of whole-body PET/CT in post-treatment dosimetry assessment.
