Currently, most applications of tomoelastography are based on MRI, which is why tomoelastography is often referred to as an advanced MRE technique. Multifrequency-MRE based tomoelastography has been used for the diagnosis of diffuse liver disease, [9] [10] [11] renal diseases such as renal allograft dysfunction, [12] lupus nephritis, [13] and immunoglobulin A nephropathy (IgAN).

Liver showing chronic passive congestion associated with tricuspid valve incompetence. So called 'nutmeg liver', Split nutmeg, for those who have never seen this appearance. Close up of congested liver showing the 'nutmeg' appearance. Congestive hepatopathy, is liver dysfunction due to venous congestion, usually due to congestive heart failure.
No single mechanism leading to steatosis exists; rather, a varied multitude of pathologies disrupt normal lipid movement through the cell and cause accumulation. [7] These mechanisms can be separated based on whether they ultimately cause an oversupply of lipid which can not be removed quickly enough (i.e., too much in), or whether they cause a failure in lipid breakdown (i.e., not enough used).
Its applications include assessment of myocardial ischemia and viability, cardiomyopathies, myocarditis, iron overload, vascular diseases, and congenital heart disease. [5] It is the reference standard for the assessment of cardiac structure and function, [6] and is valuable for diagnosis and surgical planning in complex congenital heart ...
Ischemic hepatitis, also known as shock liver, is a condition defined as an acute liver injury caused by insufficient blood flow (and consequently insufficient oxygen delivery) to the liver. [5] The decreased blood flow ( perfusion ) to the liver is usually due to shock or low blood pressure.
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.

At the end, images are "weighted" by the diffusion process: In those diffusion-weighted images (DWI) the signal is more attenuated the faster the diffusion and the larger the b factor is. However, those diffusion-weighted images are still also sensitive to T1 and T2 relaxivity contrast, which can sometimes be confusing.
