Fig 2. Feature plot MR score of mural inflammation versus ESR. Patients with an elevated ESR and a high MR score are all diagnosed GCA positive according to the ACR criteria. Patients with a low ESR and a low MR score are mostly diagnosed GCA negative. Please note that 2 of the false-negative MR findings with a very low MR score are imaged after long treatment with corticosteroids. Single points in the plot may represent >1 patient in case of identical values.
