Quantitative PET/MR imaging of lung cancer in the presence of artifacts in the MR-based attenuation correction maps.

CONCLUSION: The absence of bone and truncation artifacts have limited effect on the PET quantification of lung lesions. In contrast, susceptibility artifacts caused significant and inconsistent underestimations of the lung tumor SUVs, between test-retest scans. This may have clinical implications for patients undergoing serial imaging for tumor therapy response assessment. PMID: 31091969 [PubMed - as supplied by publisher]
