A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate. [ 1]
Myocardial perfusion imaging or scanning (also referred to as MPI or MPS) is a nuclear medicine procedure that illustrates the function of the heart muscle ( myocardium ). [ 1] It evaluates many heart conditions, such as coronary artery disease (CAD), [ 2] hypertrophic cardiomyopathy and heart wall motion abnormalities.
Purpose. evaluate cardiac function. Test of. Cardiac stress test. The Bruce protocol is a standardized diagnostic test used in the evaluation of cardiac function and physical fitness, developed by American cardiologist Robert A. Bruce. [ 1] According to the original Bruce protocol the patient walks on an uphill treadmill in a graded exercise ...
Nuclear radiation, or gamma-gamma method [3] Short wave (ultrasonic) acoustic method [4] Long wave (sonic) acoustic method [5] A pile integrity test (also known as low-strain dynamic test, sonic echo test, and low-strain integrity test) is one of the methods for assessing the condition of piles or shafts. It is cost-effective and not very time ...
The underlying principle is, under conditions of stress, diseased myocardium receives less blood flow than normal myocardium. MPI is one of several types of cardiac stress test. As a nuclear stress test, the average radiation exposure is 9.4 mSv, which when compared with a typical 2 view chest X-ray (.1 mSv) is equivalent to 94 Chest X-rays. [83]
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 . Echocardiography is routinely used in the ...
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. It is used as a non-invasive assessment of ...
Perfusion scanning. Perfusion is the passage of fluid through the lymphatic system or blood vessels to an organ or a tissue. [1] The practice of perfusion scanning is the process by which this perfusion can be observed, recorded and quantified. The term perfusion scanning encompasses a wide range of medical imaging modalities.
