Apical four chamber ultrasound view of heart. Transthoracic echocardiography (TTE) uses ultrasonic waves for continuous heart chamber and blood movement visualization. It is the most commonly used imaging tool for diagnosing heart problems, as it allows non-invasive visualization of the heart and the blood flow through the heart, using a technique known as Doppler.
Sonographer doing an echocardiogram of a child Echocardiogram in the parasternal long-axis view, showing a measurement of the heart's left ventricle. Health societies recommend the use of echocardiography for initial diagnosis when a change in the patient's clinical status occurs and when new data from an echocardiogram would result in the physician changing the patient's care.

CMR uses the same basic principles as other MRI techniques. Imaging of the cardiovascular system is usually performed with cardiac gating using an adaptation of conventional ECG techniques. [19] Cine sequences of the heart are acquired using balanced steady state free precession (bSSFP) which has good temporal resolution and intrinsic image ...
Doppler echocardiography is a procedure that uses Doppler ultrasonography to examine the heart. [1] An echocardiogram uses high frequency sound waves to create an image of the heart while the use of Doppler technology allows determination of the speed and direction of blood flow by utilizing the Doppler effect.
Cardiac ventriculography is a medical imaging test used to determine a person's heart function in the right, or left ventricle. [1] Cardiac ventriculography involves injecting contrast media into the heart's ventricle(s) to measure the volume of blood pumped.
It is a non-invasive test that can be done in many settings that include clinic exam room, inpatient rooms, and exam rooms dedicated to echo imaging. Examination involves using an echo probe at various positions or windows to obtain views of the heart (thus capturing images/videos for later playback while formally "reading" the study to come up ...
A variety of blood tests are available for analyzing cholesterol transport behavior, HDL, LDL, triglycerides, lipoprotein little a, homocysteine, C-reactive protein, blood sugar control: fasting, after eating or averages using glycated albumen or hemoglobin, myoglobin, creatine kinase, troponin, brain-type natriuretic peptide, etc. to assess the evolution of coronary artery disease and ...
The strain curves shows the gradual decrease in length during systole, and then the gradual lengthening during diastole, but strain rate fremans negative during the whole heart cycle, as the ventricular length is shorter than at end systole. Strain rate is the rate of deformation, and is negative during systole, when the ventricle shortens.
