Uhlelo lwe-VET-MRI lusebenzisa i-radio frequency pulse ye-frequency ethize emzimbeni wesilwane endaweni yamagnetic emile, ukuze ama-hydrogen protons emzimbeni ajabule futhi kwenzeke i-magnetic resonance phenomenon. Ngemuva kokuthi ukushaya kwenhliziyo kumisiwe, ama-proton ayakhululeka ukuze akhiqize amasiginali we-MR abeka imephu yesakhiwo ngaphakathi komzimba wesilwane.
1. Izinkinga i-MRI engasiza izilwane ezifuywayo ukuzixazulula
Izimo ezivamile lapho izilwane ezifuywayo zisebenzisa i-MRI ukuze zihlolwe yilezi:
1) Ugebhezi: i-suppurative otitis media, i-meningoencephalitis, i-cerebral edema, i-hydrocephalus, ithumba lobuchopho, i-cerebral infarction, isimila sobuchopho, isimila somgodi wamakhala, isimila samehlo, njll.
I-2) Inzwa yomgogodla: ukucindezelwa kwe-intervertebral disc ye-spinal nerve, i-intervertebral disc degeneration, isisu somgogodla womgogodla, njll.
3) Isifuba: isimila se-intrathoracic, isifo senhliziyo, isifo senhliziyo, i-pulmonary edema, i-pulmonary embolism, isimila samaphaphu, njll.
4) Umgodi wesisu: Kuyasiza ekuxilongeni nasekwelapheni izifo zezitho eziqinile ezifana nesibindi, izinso, amanyikwe, ubende, i-adrenal gland, kanye ne-colorectum.
5）Umgodi we-pelvic: Kuyasiza ekuxilongeni nasekwelapheni izifo zesibeletho, i-ovary, isinye, i-prostate, ama-seminal vesicles nezinye izitho.
6) Izitho nezitho: i-myelitis, i-aseptic necrosis, i-tendon kanye nezifo zokulimala kwe-ligament, njll.
2. Izinyathelo zokuqapha ukuhlolwa kwe-MRI yesilwane
1）Izilwane ezifuywayo ezinezinto zensimbi emizimbeni yazo akufanele zihlolwe nge-MRI.
I-2) Iziguli ezigula kakhulu noma ezingafaneleki ukubulawa kwezinzwa akufanele zihlolwe i-MRI.
3) Akudingekile ukwenza ukuhlolwa kwe-MRI ngesikhathi sokukhulelwa.
3.Izinzuzo ze-MRI
1) Ukulungiswa okuphezulu kwezicubu ezithambile
Ukulungiswa kwezicubu ezithambile ze-MRI ngokusobala kungcono kune-CT, ngakho-ke kunezinzuzo ezingenakuqhathaniswa ze-CT ekuhloleni izifo zesimiso sezinzwa esimaphakathi, isisu, i-pelvis nezinye izitho eziqinile!
2）Ukuhlolwa okuphelele kwendawo yenxeba
I-imaging ye-resonance magnetic ingenza izithombe ze-multi-planar kanye ne-multi-parameter imaging, futhi ingahlola ngokucophelela ubudlelwano phakathi kwesilonda nezitho ezizungezile, kanye nesakhiwo sezicubu zangaphakathi kanye nokwakheka kwesilonda.
3) Ukuthwebula kwemithambo kusobala
I-MRI ingathwebula imithambo yegazi ngaphandle kokusebenzisa ama-agent ahlukile.
4) Ayikho imisebe ye-X-ray
Ukuhlolwa kwe-nuclear magnetic ayinayo imisebe ye-X-ray futhi ayiyingozi emzimbeni.
4. Isicelo somtholampilo
Ukubaluleka kokuhlolwa kwe-MRI yesilwane akukona nje ukuhlola okukodwa kobuchopho nesimiso sezinzwa, kuwuhlobo olusha lwendlela yokuhlola ye-high-tech imaging eminyakeni yamuva, engasetshenziselwa i-tomography cishe noma iyiphi ingxenye yomzimba wesilwane.
1) Uhlelo lwezinzwa
Ukuxilongwa kwe-MRI kwezilonda zesistimu yezinzwa ezifuywayo, okuhlanganisa isimila, i-infarction, ukopha, ukuwohloka, ukukhubazeka kokuzalwa, ukutheleleka, njll, sekucishe kube yindlela yokuxilongwa. I-MRI iphumelela kakhulu ekutholeni izifo zobuchopho ezifana ne-cerebral hematoma, isimila sobuchopho, isimila esingaphakathi komgogodla, i-syringomyelia ne-hydromyelitis.
2) Umgodi wethoracic
I-MRI futhi inezinzuzo eziyingqayizivele zezifo zenhliziyo ezifuywayo, izimila zamaphaphu, izilonda zenhliziyo nezinkulu zemithambo yegazi, kanye nezixuku ze-intrathoracic mediastinal.
3）ENT
I-MRI inezinzuzo ezisobala kakhulu ekuhlolweni kwesilwane se-ENT. Ingenza i-tomography ye-nasal cavity, sinus paranasal, sinus yangaphambili, i-vestibular cochlea, ithumba le-retrobulbar, umphimbo nezinye izingxenye.
4) Udokotela Wamathambo
I-MRI nayo inezinzuzo ezinkulu ekuxilongweni kwethambo lesilwane esifuywayo, izilonda ezihlangene kanye nemisipha, futhi ingasetshenziselwa ukuxilongwa kwe-osteomyelitis yokuqala, ukuphuka kwe-anterior cruciate ligament, ukulimala kwe-meniscus, i-necrosis yekhanda le-femoral, nezilonda zezicubu zemisipha.
5) Isistimu ye-genitourinary
Izilonda zesibeletho sesilwane esifuywayo, i-ovary, isinye, i-prostate, izinso, ureter nezinye izitho zezicubu ezithambile zicacile futhi zinembile ekucabangeni kwe-magnetic resonance.
