Dongosolo la VET-MRI limagwiritsa ntchito ma radio frequency pulse pafupipafupi kwa thupi la pet mu static magnetic field, kotero kuti ma protoni a haidrojeni m'thupi amasangalala komanso zochitika za maginito zimachitika. Kugundako kukayimitsidwa, ma protoni amapumula kuti apange ma siginecha a MR omwe amajambula mawonekedwe mkati mwa thupi la chiweto.
1. Mavuto omwe MRI ingathandize ziweto kuthetsa
Nthawi zambiri pamalo pomwe ziweto zimagwiritsa ntchito MRI pakuwunika ndi:
1) Chigaza: suppurative otitis media, meningoencephalitis, edema yaubongo, hydrocephalus, abscess muubongo, infarction yaubongo, chotupa chaubongo, chotupa cham'mphuno, chotupa chamaso, ndi zina zambiri.
2) Mitsempha ya msana: intervertebral disc compression of spinal nerve, intervertebral disc degeneration, chotupa cha msana, ndi zina zotero.
3) Chifuwa: chotupa cha intrathoracic, matenda a mtima, matenda amtima, edema ya m'mapapo, pulmonary embolism, chotupa cha m'mapapo, ndi zina zambiri.
4) M'mimba: Ndiwothandiza pakuzindikira ndi kuchiza matenda a ziwalo zolimba monga chiwindi, impso, kapamba, ndulu, adrenal gland, ndi colorectum.
5）Ndizothandiza pozindikira komanso kuchiza matenda a chiberekero, ovary, chikhodzodzo, prostate, seminal vesicles ndi ziwalo zina.
6) Miyendo ndi mafupa: myelitis, aseptic necrosis, tendon ndi matenda ovulala a ligament, etc.
2. Njira zodzitetezera pakuwunika kwa MRI ya ziweto
1) Ziweto zokhala ndi zitsulo m'matupi awo siziyenera kuyesedwa ndi MRI.
2) Odwala omwe akudwala kwambiri kapena osayenerera opaleshoni sayenera kuyesedwa ndi MRI.
3) Sikofunikira kuyesa MRI pa nthawi ya mimba.
3.Ubwino wa MRI
1) Kukhazikika kwakukulu kwa minofu yofewa
Kusintha kwa minofu yofewa ya MRI mwachiwonekere kuli bwino kusiyana ndi CT, kotero ili ndi ubwino wosayerekezeka wa CT pofufuza matenda a m'katikati mwa mitsempha, mimba, pelvis ndi ziwalo zina zolimba!
2）Kuwunika kwathunthu kwa malo otupa
Kujambula kwa maginito a maginito amatha kupanga zojambula zamitundu yambiri ndi zojambula zamitundu yambiri, ndipo zimatha kuwunika mozama mgwirizano pakati pa chotupacho ndi ziwalo zozungulira, komanso kapangidwe ka minofu yamkati ndi kapangidwe ka chotupacho.
3) Kujambula kwa mitsempha ndikodziwikiratu
MRI imatha kujambula mitsempha yamagazi popanda kugwiritsa ntchito zinthu zosiyanitsa.
4) Palibe ma radiation a X-ray
Kuyeza kwa maginito a nyukiliya kulibe kuwala kwa X-ray ndipo sikuvulaza thupi.
4. Kugwiritsa ntchito kuchipatala
Kufunika kwa pet MRI kuyezetsa sikungoyang'ana kumodzi kokha kwa ubongo ndi dongosolo la mitsempha, ndi mtundu watsopano wa njira zamakono zowunikira zojambula zamakono m'zaka zaposachedwa, zomwe zingagwiritsidwe ntchito pojambula tomography pafupifupi mbali iliyonse ya thupi la chiweto.
1) Nervous system
Kuzindikira kwa MRI kwa zotupa zam'mitsempha yam'mimba, kuphatikiza chotupa, infarction, kukha magazi, kuchepa, kubadwa koyipa, matenda, ndi zina zambiri, zakhala njira yodziwira. MRI ndiyothandiza kwambiri pozindikira matenda a muubongo monga cerebral hematoma, chotupa muubongo, chotupa cha intraspinal, syringomyelia ndi hydromyelitis.
2) Chifuwa cha thoracic
MRI ilinso ndi maubwino apadera a matenda amtima wa ziweto, zotupa zam'mapapo, zotupa zamtima ndi mitsempha yayikulu, komanso ma intrathoracic mediastinal.
3) ENT
MRI ili ndi maubwino owoneka bwino pakuwunika kwa pet ENT. Iwo akhoza kuchita tomography wa m`mphuno patsekeke, paranasal nkusani, frontal nkusani, vestibular cochlea, retrobulbar abscess, mmero ndi mbali zina.
4) Orthopaedic
MRI imakhalanso ndi ubwino wambiri pa matenda a fupa la pet, mafupa ndi minofu, ndipo angagwiritsidwe ntchito pozindikira matenda osteomyelitis oyambirira, anterior cruciate ligament rupture, meniscus kuvulala, femoral head necrosis, ndi zilonda za minofu.
5) Matenda a genitourinary system
Zilonda za chiberekero cha pet, ovary, chikhodzodzo, prostate, impso, ureter ndi ziwalo zina zofewa zimakhala zomveka bwino komanso zomveka bwino pazithunzithunzi za magnetic resonance.
