Problems solved by technology

However, this method has the following problems relative to exercise load: first, the drug causes the body's ECG and cardiac output to increase passively, which does not conform to the actual cardiac load, and does not simulate the actual load state from the perspective of cardiac stress imaging; Second, drug injection is an invasive method. Drugs are injected into the blood circulation system through the vascular channel of the body and flow through the whole body through the heart; third, safety considerations, due to the influence of individual differences in subjects, especially heart disease Patients undergo rapid changes in ECG and cardiac output under the action of drugs. Whether patients can tolerate this change is unknown, and there is a certain risk

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a multifunctional load experiment exercise device for magnetic resonance imaging, a magnetic resonance imaging load experiment system and applications thereof. Background technique [0002] The load test exercise refers to the aerobic exercise process that consumes energy by isotonic contraction of the muscles. This exercise is accompanied by the decomposition of adenosine triphosphate (ATP) in the human body, and participates in the contraction function to realize the blood transport of oxygen in the blood vessels of skeletal muscles. Red blood cells and blood flow increased significantly. Vascular diseases such as atherosclerosis, diabetes, etc., due to the destruction of the peripheral blood circulatory system, the metabolic levels of skeletal muscles such as blood perfusion and tissue blood oxygen are different from normal conditions. Magnetic resonance imaging technology can ...
