Does the magnetic resonance have one hundred profit that has not been hurt
Now, there are dizzy a lot of, troublesome old man, have not waited for doctor's inspection carefully yet, it is eager to require the doctor to go ahead of the rest MRI checks. Ask his reason whether most people think this check modern techniques, if this is checked OKly, that just getting steady and sure in the heart, needn't and then other to check project at all. Then MRI checks magically like this, can totally replace other several to check? The answer is obviously denied. People lack of understanding to basic general knowledge of MRI to trace it to its cause. MRI is the magnetic resonance imaging (MagneticResonanceImaging, MRI) . It the contemporary most advanced medical image not introduced formally until the beginning of the eighties studies the inspection methods. MRI incorporates current physics, latest research results of chemistry, biology and medical science into an organic whole, the structure is complicated, modern techniques. Say briefly, it has the following several advantage: 1. While studying the inspection method in the medical image, its most outstanding advantage, have good soft tissue resolving power, it is high to compare with the resolution ratio. For example: It can clearly distinguish soft institutional framework such as muscles, the tendon, muscle membrane, fat, and can distinguish grey matter of brain and white matter accurately. 2.Cut the ability (including the cross axle location of storey diversifiedly and arbitrarily, preceded in location and any oblique location of location of form, arrow, needn't change the body posture of the person checked) . Multilevel, so the technology of the formation of image of many parameters, so can clearly reveal the interreaction between the position where pathological change locates, range and and histoorgan around, can make the focus accurately. To to determine the nature, make a reservation and not quantitative to diagnose, have unique superiority their a lot of pathological change, and not observed the dead angle. Other image can only be too far behind to catch up. 3.Belonging to has no achieving technology, and there is no X-ray radiation to damage, have really prevented other images from learning to check, damage as the X-ray or radioactive nuclide scans apparent ray radiation of looking like etc. to the human body. 4.Needing radiography pharmaceutical clearly reveals heart and blood vessel, extra agony and risk undertaken while removing the patient from accepting intubate and intravenous injection radiography pharmaceutical. But MRI has its insufficient and taboos: 1. MRI apparatus is and expensive without being lasted expenses,at present learn expenses are getting higher image in not checking, second only to PET. 2.last duration MRI long,it is last CT far not to scan by speed, it take 30 about minute for to scan to heads general, the heart takes an hour to scan, even a longer time. 3.It is very sensitive to move to the patient's body, apt to produce the false shadow, so not suitable for checking emergency call and critical patient. 4. scan to noises obvious at storehouse MRI,last patient cooperations close, keep calm, so as not to producing by claustrophobia, thus result in checking and failing. 5. MRI is insensitive to calcification,it be lasted protonned in cooking stove, be so not produced by MRI signal because calcification, unfavorable to diagnosis and differential diagnosis calcification to click. 6.The patient with pacemaker absolutely avoids. Because interfere with causing and stopping fighting. 7.Have metal, artificial limb, shell fragment, arrest blood insert, artificial the intersection of heart and valve, use stencil plate, screw, artificial head of femur,etc. while being fixed in the body, can't check, because the movement of metal foreign matter may damage important internal organs and trunk, lying in examine the position and can produce the false shadow. MRI can not at present replace other images, learn, check at all, such as CT, supersound,etc., so it is necessary to walk MRI checks, will be depended on the patient's detailed conditions by the clinician. The doctor competent MRI checks and uses rationally, have an object in view, so as not to cause the waste of medical apparatus resources, make MRI and can lighten the financial burden to check for you too rationally at the same time.
