Description

Device for magnetic resonance load experiment imaging

Technical Field

The invention relates to an auxiliary appliance for medical diagnosis, in particular to a device for magnetic resonance loading experiment imaging.

Background

Magnetic resonance imaging plays an important role in cardiac examination for medical diagnosis, and can effectively evaluate the structure and function of cardiac soft tissues. However, in the case of the subject suffering from coronary artery disease, it is difficult to accurately evaluate the disease state in a resting state due to the compensatory action of the body. Therefore, it is often necessary to increase the oxygen consumption of the heart through stress tests to achieve stress conditions, to diagnose early coronary artery disease, or to monitor and evaluate diagnosed patients.

The existing load test modes at present mainly comprise two types: 1. "exercise method", i.e. increasing the body load by physical movement of the subject. If the patient walks on a treadmill or rides on an exercise bicycle, the magnetic resonance examination is carried out after the load requirement is met, the biggest defect of the method is that the patient cannot be monitored in real time, and the patient is in a state of stopping moving when scanning. The improved exercise mode is as disclosed in Chinese patent application No. 201810012520.2, a multifunctional load experiment exercise device and system for magnetic resonance imaging and its application, a horizontal pedal exercise device is arranged on a lying platform of a magnetic resonance imaging device, and the exercise load during magnetic resonance scanning can be realized by using the reciprocating pedal exercise. 2. The "pharmacotherapy" is the injection of vasodilatory drugs to increase cardiac load. The commonly used drugs include dipyridamole, adenosine, GAAA, dobutamine, etc. However, the load induced by the drug is different from the heart load in the physiological state, and once the drug is injected into a human body, the controllability is poor, and part of the tested people have the risk of adverse drug reactions.
