The Animal MRI Core has performed MRI studies on 14 projects, of which 8 are actively imaging, 3 with data review or manuscript in progress, 3 with papers published on past years data, in the period from Oct. 1, 2014 to Sept 30, 2015. Projects are listed alphabetically by Principal Investigator: 1. Arai , Andrew; NHLBI protocol H-0176, fellow Beliveau. Rat Myocardial Fibrosis. MRI microimaging of rat heart in experimental and age-related fibrosis, acute MI, and chronic MI. Correlation of microimaging cellular level areas of fibrosis to microscopy and histopathology. 2.

Bustin, Michael, NCI protocol. Staff scientist Furusawa. Published a paper in 2015 based on a HMGN5 overexpressing transgenic mouse model imaged for cardiac function and anatomy in the Core from 2009-11. 4.
