MR imaging was applied for the detection of systemic amyloidosis. Two novel MR techniques were applied to transgenic mouse models of amyloidosis: amide proton transfer (APT) in the kidney and equilibrium contrast MR (EQ-MR) in the heart and liver. Both EQ-MR and APT techniques were able to detect minor amyloid deposits and EQ-MR was demonstrated to be more sensitive to amyloid deposition in the heart than the calculation of cardiac functional parameters. These MR techniques may have applicability in early diagnosis of amyloidosis and in preclinical amyloidosis therapy studies.
