Strain rate imaging is a method in echocardiography (medical ultrasound) for measuring regional or global deformation of the myocardium (heart muscle). The term "deformation" refers to the myocardium changing shape and dimensions during the cardiac cycle.
In the fields of cardiology and medical imaging, speckle tracking echocardiography (STE) is an echocardiographic imaging technique. It analyzes the motion of tissues in the heart by using the naturally occurring speckle pattern in the myocardium (or motion of blood when imaged by ultrasound ).
An important potential finding with echo is McConnell's sign, where only the RV apex wall contracts; [7] it is specific for right heart strain and typically indicates a large PE. [8] On an electrocardiogram (ECG), there are multiple ways RV strain can be demonstrated. A finding of S1Q3T3 [b] is an insensitive [10] sign of right heart strain. [11]
Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging, using standard ultrasound or Doppler ultrasound. [1] The visual image formed using this technique is called an echocardiogram, a cardiac echo, or simply an echo.
Only a CT scan, MRI, and transesophageal echocardiogram can identify an aortic dissection. Chest X-rays and EKGs are not enough to rule out the condition. ... Injury to the chest, extreme strain ...
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.
In echocardiography, strain can be measured by using Tissue Doppler Imaging (TDI) or Speckle Tracking Echocardiography (STE). Using MRI, strain and deformation can be measured, noninvasively, using MRI Tagging and Harmonic Phase Analysis (HARP), [1] Strain Encoding (SENC), or Tissue Tracking. The latter is similar to STE, although the MRI ...
Echocardiography can be used to directly visualise right ventricular wall thickness. The preferred technique is the trans-oesophageal approach giving a view of 4 chambers. The preferred technique is the trans-oesophageal approach giving a view of 4 chambers.
