1. To analyze the technical adjustments to perform diffusion weighted imaging of the heart.
2. To review real and potential clinical applications of cardiac DWI.
Introduction With recent advancements in functional and molecular imaging,
MRI based sequences have made an important improvement in the characterization of normal and pathological tissues.
Diffusion weighted imaging (DWI) has become a powerful tool in that terms,
not only differentiating benign versus malignant process,
but also resulting in an oncological biomarker with prognostic implications in several regions of the body. 2.
Physical basis and technique of DWI DWI focuses on the...

Clinical applications 4.1.
Ischemic heart disease Ischemic heart disease constitutes the leading cause of death in developed countries,
with an estimated prevalence of 8,5 million for myocardial infarction and 10,2 million for angina pectoris.
Is common between 40 to 65 year-old individuals and is more lethal in women. Myocardial infarction is defined as myocyte death secondary to prolonged ischemia due to overwhelmed cellular repair mechanism by inadequate blood supply to the myocardium...
1. DWI of the heart is a feasible and reproducible technique 2.
Can depict the presence of myocardial edema in ischemic and inflammatory heart diseases 3.
Helps in the characterization of cardiac masses ,
although there is limited experience. 4. Despite of no existing data,
could be useful in the follow up and treatment monitoring in both acute myocarditis and cardiac masses.
