Description
Technical field
The invention belongs to medical instruments fields, are related to a kind of magnetic resonance imaging multi-functional load test telecontrol equipment and magnetic
Resonance image-forming load test system and its application.
Background technology
Load test movement refers to the aerobic exercise process using the isotonic contraction of muscle as consumed energy, carries out this kind
With the decomposition of the atriphos (ATP) in human body, participation contractile function realizes to be transported in skeletal muscle blood vessel for movement
The erythrocyte of oxygen and blood flow showed increased.The disease of vascular such as blood vessel scleratheroma, diabetes etc., due to peripheral blood
The destruction of fluid circulation causes the metaboilic levels such as skeletal muscle such as blood perfusion and tissue oxygenation to be had differences with normal condition.Profit
Muscle metabolism level, muscle metabolism level and the exercise load state of people's tranquility can be assessed with resonance imaging techniques
Under there are larger difference, the different shape of metabolism that this species diversity in the quiescent state can not show people is fully exposed.
In order to which the muscle metabolism under application resonance imaging techniques assessment human body exercise load state is horizontal, institute is public at present
The lower limb load exercise experiment opened and equipment therefor have following several technical solutions：To the training of human body lower limbs load exercise
Skinner-Gardner tablets test (Gardner AW, Skinner JS, et al.Progressive vs.single-
Stage treadmill tests for evaluation of claudication.Med Sci Sports Exerc), it should
Experiment be walked on a treadmill using people certain time as apply leg load in a manner of；The front end dorsiflex of people's foot in magnet
Movement lifts load exercise mode (the blood flow filling after skeletal muscle movement and ice compress of weight (5.58kg) by nylon rope and pulley
Note and the function MRI of water diffusion researchs, Li Feng, doctoral thesis)；The Toe-flexion experiments of foot load training
(Jie Zheng,Mary K.Hastings,David Muccigross,et al.Non-contrast MRI perfusion
Angiosome in diabetic feet.Eur Radiol), which is that foot bones flesh is carried out in a manner of bending toe
Load exercise；Simultaneously magnetic resonance compatible (David is trained leg together with foot by Plantar-flexion gauges
C.Isbell,Frederick H.Epstein,et al.Calf Muscle Perfusion at Peak Exercise in
Peripheral Arterial Disease:Measurement by First-Pass Contrast-Enhanced
Magnetic Resonance Imaging.J Magn Reson Imaging).But in said program, Skinner-
The experiment of Gardner tablets is that human body completes load exercise beyond magnetic resonance, carries out magnetic resonance imaging subsequently into magnet, therefore
It can not reflect the level that skeletal muscle is metabolized in sport training process in real time；The load of weight is lifted by nylon rope and pulley
Movement can not quantify exercise intensity, and it is tired out to easily lead to human motion；Toe-flexion experiments are also can not be by the movement of foot
Quantification of intensities；Plantar-flexion gauges are the device of similar two bicycle pedals, subject according to setting speed
Degree (enclosing for one minute 10~12) is moved, and is terminated until can not effectively scrunch again for training, since subject makes simultaneously
It is moved with foot, leg and leg muscle, thus not can determine that the exercise tolerance of which part muscle reaches peak, lacked accurate
The positioning of true target skeletal muscle, it is difficult to assess the exercise tolerance level of each position muscle.
In resonance imaging techniques field, cardiac load magnetic resonance imaging is formed also by drug injection in research at present
Method, wherein K Mc Entee etc. are by giving dog to inject dobutamine (K Mc Entee, H Amory, et
al.Dobutamine cardiac stress testing in conscious healthy dogs.Esvim Meeting,
1996) achieve the purpose that cardiac load and later KK Balan, T Leitha etc. respectively by give patient injection adenosine and
Method (KK Balan, the M Critchley.Is the dyspnea during adenosine cardiac of persantine
stress test caused by bronchospasm.American Heart Journal,2001,142(1):142.T
Leitha,M Gwechenberger,S Falger-Banyai.Acute effects on pulmonary airflow of
intravenous dipyridamole cardiac stress testing.European Journal of Nuclear
Medicine&Molecular Imaging,1995(22):1408-1410) carry out cardiac load imaging.By injecting drug
The principle of method is promotes the electrocardio of body and cardiac output passively to increase, and then simulation represents heart and is in load condition situation
Under.But this method has the following problems compared with exercise load：First, drug so that the electrocardio of body and cardiac output are passive
Increase, do not meet the situation of real heart load, the load condition for not having simulation actual for cardiac load imaging；Second,
Injection drug is invasive method, and drug into circulatory system and flows through whole body by the blood vessel access injection of body through heart
Everywhere；3rd, the considerations of security, because the influence of individual subject's difference, especially heart disease patients are under drug effect
Electrocardio and cardiac output quickly change, patient can be resistant to it is this variation it is unknowable, there are certain risks.
