Aims and objectives
Late gadolinium enhancement(LGE) is recognized as a useful and efficient tool to evaluate the presence of myocardial necrotic,
edematous or fibrotic areas.
The aim of this study was to evaluate the two-dimensional (2D) phase-sensitive inversion recovery (PSIR) in comparison with 2D inversion recovery sequences to establish which one offers the best image and diagnostic quality for myocardial fibrotic lesions assessment in non ischaemic heart disease.
Methods and materials
1.
Population
We reviewed 80 consecutive patients (53 male and 27 female patients; age range: 25–82 years; mean age:58.6 years) who underwent cardiac MRI with late gadolinium enhancement(LGE) sequences including both breath-held 2D PSIR and breath-held 2D IR sequences ,
from January 2016 through January 2018.
2.
Etiologies:
We included patients who underwent LGE–MRI due to hypertrophic cardiomyopathy(n=19),
dilated cardiomyopathy (n=10),
sarcoidosis (n=8),
amyloidosis (n=10),
non compaction of left ventricular (n=3) and myocarditis (n=30) on the basis of clinical,
laboratory,
electrocardiographic,
echocardiographic criteria.

Conclusion
