Fibromas are nonencapsulated tumors and extend into the surrounding myocardium. Central portions of the tumor are composed of hyalinized fibrous tissue, often with multiple calcification foci and ...

(B) A section of myocardium showing muscle fibre hypertrophy, muscle fibre disarray, and interstitial fibrosis. (Stain: Movat pentachrome, original magnification x 20).

Molecular imaging of the myocardium, however, requires the imaging agent to be small, sensitive (nanomolar levels or better), and able to gain access to the interstitial space. Several novel ...

Cardiac MRI was also used by Kwon et al. to investigate the relationship between the presence of myocardial fibrosis (scarring) and small intramural coronary arteriole dysplasia (SICAD).
