Left ventricular mass or LVM refers to the mass of the left ventricle of the heart. Left ventricular mass index or LVMi is LVM divided by body surface area . LVM is usually estimated using linear measurements obtained from echocardiography , [ 1 ] but can also be calculated using CT or MRI images. [ 2 ]
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
Left ventricular mass can be further estimated based on geometric assumptions of ventricular shape using the measured wall thickness and internal diameter. [7] Average thickness of the left ventricle, with numbers given as 95% prediction interval for the short axis images at the mid-cavity level are: [ 8 ]
Velocity Time Integral is a clinical Doppler ultrasound measurement of blood flow, equivalent to the area under the velocity time curve. The product of VTI (cm/stroke) and the cross sectional area of a valve (cm2) yields a stroke volume (cm3/stroke), which can be used to calculate cardiac output.

A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart.
After two more free throws by Chatfield and a 3-pointer by Jones, Iowa State extended its lead to 61-38 with 6:56 remaining. Roach finally stopped the run with a 3-pointer, but Baylor still ...
Tissue Doppler echocardiography (TDE) is a medical ultrasound technology, specifically a form of echocardiography that measures the velocity of the heart muscle through the phases of one or more heartbeats by the Doppler effect (frequency shift) of the reflected ultrasound.
