Investigation of cardiomyopathy using cardiac magnetic resonance imaging part 2:Rare phenotypes

Cardiac magnetic resonance imaging(CMRI) has emerged as a useful tertiary imaging tool in the investigation of patients suspected of many different types of cardiomyopathies.CMRI images are now of a sufficiently robust quality to enable high spatial and temporal resolution image acquisition.This has led to CMRI becoming an effective non-invasive imaging tool for many cardiomyopathies.In this two-part review we outline the typical sequences used to image cardiomyopathy and present the imaging spectrum of cardiomyopathy.Part Ⅰ focused on the current classification of cardiomyopathy,the basic CMRI sequences used in evaluating cardiomyopathy and the imaging spectrum of common phenotypes.Part Ⅱ illustrates the imaging spectrum of the more rare phenotypes.
