FIGURE 1.
Mass-to-Cardiac Length Ratio Measurement and Fibroma LGE Pattern
(A) The mass-to-cardiac length ratio measurement = largest mass length (in any view) ÷ cardiac length (4-chamber [4C] view). (B) A characteristic pattern of well-circumscribed hyperenhancement with patchy dark regions is commonly seen in fibromas (white arrows). LGE = late gadolinium enhancement.
