: Some study subjects or cohorts have been previously reported in a previously published paper (Gowdra HV et al Neuroendocrine liver metastasis treated by using intraarterial therapy: volumetric functional imaging biomarkers of early tumor response and survival. Radiology 2013; 266:502–513). We have reported on 55 out of 111 patients included in the current study. However, the prior report focused on the volumetric changes in multiparametric MR post TACE. The current study doubled the sample size and focused on a completely different aspect, the assessment of hepatic tumor burden.
