Why the study?
What are the MR imaging features of normal right atrial fibromuscular elements, and how frequently are they visualized?
What are the MR imaging features of normal right atrial fibromuscular elements, and how frequently are they visualized?
Normal right atrial fibromuscular structures, such as the crista terminalis and Chiari network, are frequently visualized on cardiac MRI and should be recognized to prevent misdiagnosis as cardiac tumors or masses.

Supports recognition of frequent normal right atrial variants on cardiac MRI to prevent misdiagnosis; leaves open prospective assessment of diagnostic impact.
Mirowitz et al. (1992) studied this question.
