Some study subjects or cohorts have been previously reported in a published study on T1 and T1\u03c1 mapping in portal hypertension (Hectors et al [\n                      \n                      ]), native and contrast-enhanced T1 (Altinmakas et al [\n                      \n                      ]), DCE-MRI (Hectors et al [\n                      \n                      ]) and MR elastography (Kennedy et al [\n                      \n                      ]). A subset of 10 patients was also included in a technical paper comparing two 4D flow methods (Bane et al [\n                      \n                      ]). We have presented preliminary results of this study in oral presentations at the annual meetings of the Society of Abdominal Radiology (2024, 2020), the Society of Advanced Body Imaging (2023), and the International Society of Magnetic Resonance in Medicine (2020).","order":7,"name":"Ethics","group":{"name":"EthicsHeading","label":"Study subjects or cohorts overlap"}},{"order":8,"name":"Ethics","group":{"name":"EthicsHeading","label":"Methodology"}}]}}
