Description
Technical field
The present invention relates to a kind of diagnostic system, specifically a kind of MRI image diagnostic system.
Background technology
MRI i.e. magnetic resonance imaging, English full name are:Magnetic Resonance Imaging.Often people
The atomic nucleus utilized has: 1H、11B、13C、17O、19F、31P.This technology be born at the beginning of be once referred to as nuclear magnetic resonance into
Picture, arrive in the early 1980s, the NMR as medical science new technology is imaged(NMR Imaging)One word is increasingly public institute
It is familiar with.With the installation of big magnet, someone starts to worry that alphabetical " N " may produce negative shadow to the development of magnetic resonance imaging
Ring.In addition, " nuclear " one word is also easy to the association for making corpsman,hospital produce another Nuclear Medicine Dept to Magnetic Resonance (MR) Room/ MRI Room.
Therefore, in order to protrude the advantages of this Examined effect does not produce ionising radiation, while with using the nuclear medicine phase of radioactive element
Difference, radiologist and equipment manufacturers agree to " Magnetic resonance imaging art " to be referred to as " magnetic resonance imaging(MRI)”.
The most frequently used core of magnetic resonance is hydrogen nuclei proton(1H), it is also wide in tissue because its signal is most strong
General presence.Influenceing nuclear magnetic resonance image factor includes:(a) density of proton;(b) relaxation time length;(c) blood and cerebrospinal fluid
Flowing;(d) paramagnet (e) protein.
Nuclear magnetic resonance image GTG feature is that magnetic resonance signal is stronger, then brightness is bigger, and the signal of magnetic resonance is weak, then brightness
Also it is small, from white, grey to black.
Various tissue nuclear magnetic resonance image GTG features are as follows:Adipose tissue, cancellous bone are white;Myelencephalon, marrow are in white
Grey;Internal organ, muscle are in canescence;Liquid, normal speed stream blood are in black;Cortex of bone, gas, gassiness lung are in black.
Another feature of nuclear magnetic resonance is that working fluid does not produce signal and is referred to as flowing effect or flow void effet.Therefore
Blood vessel is canescence tubular structure, and blood is the black of no signal.Blood vessel is so set to be easy to separate with soft tissue.Normal ridge
There is cerebrospinal fluid encirclement around marrow, cerebrospinal fluid is black, and the dura mater for having white is set off by fat, spinal cord is shown as white
Strong signal structure.
Nuclear magnetic resonance(MRI)The imaging applied to each system of whole body diagnoses.Best results are cranium brains, and its spinal cord,
Cardiovascular injuries, joint bone, soft tissue and pelvic cavity etc..Each chamber, big blood vessel and valve can be not only observed angiocardiopathy
The dissection change of film, and Ventricle Analysis can be made, qualitative and sxemiquantitative diagnosis is carried out, multiple sectional drawings, spatial discrimination can be made
Rate is higher, heart and lesion overall picture, and its relation with surrounding structure is shown, better than other x-ray imaging, two-dimensional ultrasound, nucleic
And CT examination.When being diagnosed to Encephalomyelopath, coronal, sagittal and cross section picture can be made.
MRI machine in present various big hospital is all more various, but present this kind of MRI machine diagnosis control is more not
Just, it is impossible to meet present requirement.
