Update Figure 3 and its caption; current manuscript title in the citation

Figure 3 regenerated in the submitted 2x2 layout from the final patient-wise results, external early arterial phase omitted (one examination). Caption follows the new layout. Citation title updated to the revised manuscript title. Field-strength note now names both institutions included in that analysis.

 ### Performance across sequence types and liver morphology

-Radar plots of patient-wise mean Dice for the three models, by MRI sequence type (**A**, internal test; **B**, external test) and by morphologic subgroup (**C**, internal; **D**, external). Each axis is one sequence type or subgroup; the values under each plot list the models in the same order as the axes. LiverSegMRI encloses both comparators on every axis.
+Radar plots of patient-wise mean Dice for the three models, by MRI sequence type (top) and by morphologic subgroup (bottom), in the internal (left) and external (right) test sets. Each axis is one sequence type or subgroup. LiverSegMRI encloses both comparators on every axis. The external early arterial phase is omitted because it contained a single examination.
 
-Relative to conventional T1-weighted phases, Dice falls by 0.011 on DWI and 0.016 on ADC for LiverSegMRI, against 0.071 and 0.085 for TotalSegmentator MRI and 0.181 and 0.145 for MRAnnotator. Subgroup performance (**C**, **D**) stays close to the whole-cohort level for LiverSegMRI in cirrhosis, irregular borders, prior resection, left lobe extension, exophytic lesions and ascites.
