Advantages and disadvantages of different cardiac imaging modalities in the diagnosis of cardiac involvement of acromegaly.

Cardiac imaging modality	Advantages	Disadvantages
GLS/2DSTE	$\bullet$ Available everywhere	$\bullet$ Needs good image
	$\bullet$ Low-cost	$\bullet$ Does not detect myocardial fibrosis
3DSTE	$\bullet$ Offers additional parameters	$\bullet$ Low feasibility in everyday practice
	$\bullet$ Eliminates directional limits of 2D speckle tracking	$\bullet$ Accuracy highly depends on technical skills of operator
	$\bullet$ Time-saving	$\bullet$ Not yet readily available in developing countries
Cardiac MRI	$\bullet$ Higher spatial resolution	$\bullet$ Expensive
	$\bullet$ Gold standard for the assessment of myocardial mass	$\bullet$ Not readily available in developing countries
	$\bullet$ Can precisely detect myocardial fibrosis	$\bullet$ Cannot be used to patients with metal implanted on their bodies
	$\bullet$ Can precisely assess RV systolic function
