Aims and objectives: In recent years, evaluations using MRI without contrast agent have been increasing. As for the cardiac muscle, reports of imaging without contrast agent have also been increasing. On the other hand, in order to visualize an area with increases in diseased extracellular fluid fractions by using MRI, [...]

Methods and materials: Subjects: Forty-five patients with cardiomyopathy myocardial infarction or cardiac sarcoidosis. Equipment: Philips Ingenia 3.0T Release, dS Torso coil Parameter:                 Contrast enhancement: Balanced            [...]

Results: The contrast of this imaging method is median AMI 0. 591, non-AMI 0. 489. The contrast of the delay enhancement is median AMI 0.730, non-AMI 0.709. The contrast of the T2-weighted imaging is median AMI 0. 250, non-AMI  0.176.  (Table.1)(Table.2)   Although this imaging method showed [...]

Conclusion: The  combination of Balanced SSFP and Inversion Recovery made it possible to depict lesions with strong T2-weighted images which were not able to be visualized with the conventional T2-weighted imaging.
