Tangoganizani kuti mnzanu akuchitidwa opaleshoni yochotsa chotupa m'gawo lovuta kwambiri la ubongo wake. Madokotala ndi osamala kwambiri pochita opaleshoniyo. Koma kodi amadziwa bwanji ngati chotupacho chachotsedwa kwathunthu kapena ngati pali chidutswa chaching'ono chotsala? Pambuyo pa opaleshoniyo, ngati mutachitanso scan patatha masiku angapo, mutha kudziwa motsimikiza. Ngati pali chidutswa chaching'ono chotsala, muyenera kuchitanso opaleshoni ina, sichoncho? Ukadaulo wapaderawu womwe tikukambirana lero ukugwiritsidwa ntchito ngati yankho la mavuto otere.
Mwachidule, kodi iMRI ndi chiyani?
Dzina lonse la iMRI ndi Intraoperative Magnetic Resonance Imaging . "Intraoperative" amatanthauza "panthawi ya opaleshoni." Izi zikutanthauza kuti ndi MRI scan yomwe imachitika pamene opaleshoni ikuchitidwa . Izi zimathandiza gulu lanu la opaleshoni kuona ziwalo, minofu, ndi zinthu zina mkati mwa thupi lanu momveka bwino pamene opaleshoni ikuchitidwa.
Tangoganizirani dokotala akuchotsa chotupa muubongo. Akhoza kuchita MRI scan atangochotsa chotupacho, opaleshoni isanathe, kuti aone, "Kodi ndinachotsa chotupa chonsecho? Kapena pali zidutswa zing'onozing'ono zomwe zatsala?" Ngati scan ikusonyeza kuti pali chidutswa chaching'ono chotsala, akhoza kuchotsa gawolo nthawi yomweyo.
Ubwino waukulu wa izi ndi wakuti kudziwa kuti pali ziwalo zina za chotupa zomwe zatsala pambuyo pa opaleshoni kungachepetse kwambiri chiopsezo chochitidwa opaleshoni yachiwiri.
Kodi kusiyana pakati pa MRI yokhazikika ndi iMRI ndi kotani?
Kusiyana kwakukulu komanso kokha pakati pa ziwirizi ndi nthawi yomwe imatenga kuti ichite .
- Kujambula MRI nthawi zonse: Izi zimachitika kuti mudziwe matenda kapena kukonzekera opaleshoni. Mumalowa mu makina a MRI monga mwachizolowezi ndipo mumajambula chithunzichi.
- IMRI: Izi zimachitika pamene opaleshoni ikuchitidwa , mkati mwa chipinda chochitira opaleshoni.
Mwachidule, chimodzi chimachitika opaleshoni isanayambe, ndipo china chimachitika panthawi ya opaleshoniyo.
N’chifukwa chiyani madokotala amagwiritsa ntchito ukadaulo uwu pa opaleshoni?
Maopaleshoni ena, makamaka opaleshoni ya ubongo, ndi ovuta kwambiri. Ngakhale kusiyana kwa milimita imodzi kungakhale ndi zotsatirapo zazikulu. Dokotala amafunika chithunzi chomveka bwino komanso chowoneka bwino panthawi ya opaleshoni kuposa zomwe angaone ndi maso awo kapena kudzera mu maikulosikopu. Pamenepo ndi pomwe kufunika kwa iMRI kumaonekera bwino.
Nazi zina mwa njira zomwe zimagwiritsidwa ntchito kwambiri pa ukadaulo wa iMRI:
| Mtundu wa opaleshoni | Thandizo kuchokera ku iMRI |
|---|---|
| Kuchotsa Chotupa cha Ubongo | Kutsimikizira ngati chotupacho chachotsedwa kwathunthu, kapena ngati ziwalo zambiri zitha kuchotsedwa popanda kuwononga minofu yathanzi. Izi ndizofunikira kwambiri pa zotupa monga glioma . |
| Chotupa cha pituitary | Mukachotsa zotupa kuzungulira pituitary gland, gawo lovuta kwambiri la ubongo, kuti muwone ngati zawonongeka mitsempha yofunika komanso mitsempha yamagazi yomwe ili pafupi. |
| Kulimbikitsa Ubongo Kwambiri (DBS) | Mukayika ma electrode mkati mwa ubongo kuti mupeze matenda monga Parkinson's , onetsetsani kuti ayikidwa pamalo oyenera. |
| Opaleshoni ya Khunyu | Kuzindikira bwino mbali ya ubongo yomwe imayambitsa khunyu ndikuwona ngati yachotsedwa kwathunthu. |
| Kuchotsa ubongo (craniotomy) | Mu opaleshoni iliyonse yovuta yokhudza ubongo, kuti muone momwe ubongo ulili (kutupa, kutuluka magazi) kumapeto kwa opaleshoniyo. |
Kodi makina a iMRI awa amagwira ntchito bwanji?
Kujambula kwa MRI ndi makina omwe amagwiritsa ntchito maginito ndi mafunde a wailesi kujambula zithunzi za mkati mwa thupi. Ndicho chimene chimachitika mu iMRI. Simudzamva chifukwa muli pansi pa mankhwala oletsa ululu ndipo nthawi zambiri simukudziwa kalikonse.
Umu ndi momwe zimagwirira ntchito, mwachidule:
Matupi athu opitirira theka amapangidwa ndi madzi. Madzi amapangidwa ndi maatomu a haidrojeni ndi okosijeni. Mkati mwa atomu ya haidrojeni iyi muli tinthu totchedwa pulotoni . Ma protoni awa ali ndi mphamvu yamagetsi, ndipo amazunguliranso.
Makina a MRI amatumiza mphamvu yamphamvu ya maginito m'thupi lanu. Chomwe chimachitika ndichakuti ma protoni onsewa m'thupi lanu amalunjika mbali imodzi, ngati singano ya kampasi yoloza kumpoto.
Kenako, makina a MRI amatumiza mafunde a wailesi kudzera mu mphamvu yamaginito iyi. Izi zili ngati shutter ya kamera yomwe ikutenga chithunzi. Mafunde a wailesi awa amasokoneza kwakanthawi kulumikizana kwa ma proton. Mafunde a wailesi akasiya, ma proton amabwerera ku kulumikizana kwawo koyambirira. Kusinthaku kumatengedwa ndi sikirini mumakina. Deta imatumizidwa ku kompyuta, yomwe imapanga chithunzi chomveka bwino cha magawo atatu (3D).
Kodi ndingakonzekere bwanji iMRI?
Ndipotu, simukuyenera kukonzekera iMRI chifukwa zimachitika panthawi ya opaleshoni yanu. Chomwe muyenera kuchita ndikukonzekera opaleshoni yanu bwino. Tsatirani malangizo a dokotala wanu monga momwe angakuuzeni.
Mudzakhala mukupatsidwa mankhwala oletsa ululu panthawi ya opaleshoni, kotero mwina mudzakhala mukugona. Padzakhala phokoso pamene makina a MRI akugwira ntchito, koma simudzamva chifukwa cha mankhwala oletsa ululu. Nthawi zina, pamakhala njira zochitira opaleshoni mukadzuka. Zikatero, gulu lachipatala lidzakukonzekeretsani opaleshoniyo ndikuonetsetsa kuti muli bwino panthawi yojambula.
Zinthu zomwe muyenera kuuza dokotala wanu musanachite opaleshoni:
- Ndiko kuti, ngati muli ndi pakati .
- Ngati muli ndi chinthu chilichonse chachitsulo chomwe chaikidwa m'thupi lanu. Mwachitsanzo, pacemaker, mbale zachitsulo zomwe zaikidwa mkati mwa thupi, mafupa opangidwa, ndi zina zotero. Maginito amphamvu mu MRI angayambitse kusuntha kapena kusagwira ntchito bwino. Izi ndi zoopsa. Chifukwa chake, ngati mwadziwitsidwa pasadakhale za izi, gulu lachipatala lidzachitapo kanthu kofunikira kuti mutetezeke.
- Musanachite opaleshoni, muyenera kuchotsa zinthu zonse zachitsulo m'thupi lanu, monga zodzikongoletsera, ndolo, mapini a tsitsi, ndi mawaya achitsulo m'kabudula wanu wamkati .
Kodi ubwino wa iMRI ndi wotani?
Pali ubwino wambiri wogwiritsa ntchito ukadaulo wa iMRI.
- Zithunzi zooneka bwino kwambiri: Malo a thupi lomwe likuchitidwa opaleshoni amatha kuwoneka bwino komanso mwatsatanetsatane.
- Zambiri zenizeni: Zithunzi izi zitha kuwonedwa panthawi ya opaleshoni, zomwe zimathandiza kuti zisankho zichitike mwachangu.
- Kuwunika kusintha: Mutha kuona nthawi yomweyo momwe dera lasinthira panthawi ya opaleshoni (monga mutachotsa chotupa).
- Kupewa mavuto: Zithunzi zomveka bwino izi zitha kuchepetsa kwambiri mavuto omwe angachitike pambuyo pa opaleshoni.
- Sizimawononga thupi: Ukadaulo wa MRI sugwiritsa ntchito ma radiation monga X-ray kapena CT scans, kotero suvulaza thupi.
Dokotala amatha kuona zotsatira izi mkati mwa masekondi ochepa kuchokera pamene wachitidwa scan, zomwe zimamulola kuti apitirire ku gawo lotsatira la opaleshoniyo popanda kuchedwa.
Uthenga Wopita Nawo Kunyumba
- IMRI ndi MRI scan yapadera yomwe imachitika panthawi ya opaleshoni.
- Cholinga chachikulu cha izi ndikupatsa madokotala omwe akuchita opaleshoni mwayi wowona bwino mkati mwa thupi ndikukhala ndi moyo.
- Izi zimathandiza kutsimikizira nthawi yomweyo ngati chotupacho chachotsedwa kwathunthu, makamaka pa opaleshoni yovuta monga kuchotsa chotupa cha muubongo.
- Izi zimachepetsa kwambiri kufunika kwa opaleshoni yachiwiri.
- Ngati mukufuna kuchitidwa opaleshoni ya iMRI, onetsetsani kuti mwadziwitsa dokotala wanu pasadakhale za zipangizo zilizonse zachitsulo, monga pacemakers, zomwe mwaika m'thupi lanu.
