BMC Medical Imaging

Table 12 Overview of identified low-value examinations in cardiac imaging

Type of imaging	Reason for examination	Outcome	Suggested practice by included study/studies	References
Stress myocardial perfusion imaging	Cardiac disease	27% relevant findings	Use risk stratification to screen patients	[264, 265]
Stress echocardiography	Cardiac disease	18% relevant findings		[265]
Routine transthoracic echocardiography	Acute ischemic stroke	8.5% change in management		[267]
Elective coronary angiography	Coronary heart disease	40% relevant findings	Use risk stratification to screen patients	[268]
Left ventriculography during angiography	Coronary heart disease	Low diagnostic accuracy	Echocardiography, nuclear scintigraphy, or MRI have better diagnostic results	[269]
PET/CT	Infective endocarditis	10% change in treatment		[266]
