Kuyini i-MRI Scan?

Imiphumela ye-MRI ingathatha izinsuku ezimbalwa kuye ngokuthi isikhungo sinjani. Buza umhlinzeki wakho wezempilo noma uchwepheshe we-MRI ngesikhathi okufanele usilinde nokuthi yini okufanele uyicabangele ngemiphumela engaba khona.

Odokotela bemisebe bahumusha ama-MRI scans bese bethumela umbiko we-radiology kudokotela ukuze babukeze okutholakele okubalulekile futhi bancome izinyathelo zesikhathi esizayo.

I-magnetic resonance imaging (MRI) ihlola izitho nezakhiwo ezingaphakathi komzimba wakho isebenzisa amagagasi anamandla kamagnethi kanye nomsakazo. Abahlinzeki bezempilo basebenzisa ama-MRI scans ukuthola izifo eziningana, kusukela kuma-ligaments aqhekekile kuya kuma-tumors. I-magnetic resonance imaging (MRI) iwusizo ekufundeni ubuchopho kanye nomgogodla.

Itafula lingena kwisilinda esikhulu esisetshenziselwa ukuskena kwe-MRI futhi liqukethe i-magnet ngesikhathi sokuhlolwa, okudala insimu enamandla kazibuthe uma isetshenziswa.

Izicubu ezithambile zakhiwe ngama-molecule amanzi, kanti insimu yamagnetic isebenzisana nezinhlayiya ezincane kakhulu ezikhona emanzini ezibizwa ngokuthi ama-proton. Lapho isithwebuli se-MRI sithumela amaza omsakazo ezicutshini ezithambile, ama-proton anamandla adala i-echo.

I-MRI ingasiza ekuboneni ukukhubazeka kwesakhiwo okucindezela inzwa, okuvumela ukwelashwa ngaphambi kokuba kuvele umonakalo wenzwa ongenakuguqulwa. Ngokuvamile, ukuhlolwa kwezinzwa kuhlonza ukulimala kwenzwa okuqinisekiswa yimiphumela ye-MRI scan. Kuyasiza ekuboneni umonakalo wenzwa njengoba kutholakala ku-MRI nalapho kutholakala khona.

Udokotela we-radiographer uzohlola ama-scan bese ewachaza. Uzobe eseshayela udokotela ukuze amtshele ngemiphumela. Le nqubo ingathatha izinsuku eziningi ngaphandle kokuthi ukuskena kube yisimo esiphuthumayo. Abantu bangase bafune ukubuka ama-scan abo ngokuxhumana nodokotela wabo. Udokotela angase anqume ukuthi ukuskena okulandelayo kuyadingeka futhi achaze ukuthi kungani.

Ukwanda kwe-metastases ebuchosheni kubalulekile ekuqaliseni kweziguli ezinomdlavuza wesistimu. Ezimweni ezithile, bathole ukwehla kwe-metastases ebuchosheni ngokwezokwelapha ngezimpawu ezintsha zemizwa, ngaleyo ndlela bebonisa izithombe kulezi ziguli.

Ukufinyelela okwengeziwe kwi-MRI yomzimba wonke kuvumela ukutholakala okubucayi kakhulu kwe-metastases yomnkantsha kanye nokwanda kwesimila ngaphandle komnkantsha.

Ezimweni zokuvuvukala nokutheleleka, i-MRI ivumela ukuhlolwa kokubandakanyeka kwezicubu ezithambile kanye nomnkantsha wamathambo. I-MRI ibucayi kakhulu kune-ultrasound, i-X-ray, noma i-CT ekutholeni izilonda zokuvuvukala kanye nokuguguleka.

Ukuvuvukala kungabonakala ku-MRI yobuchopho. Izindawo ezithintekile ukuvuvukala zimunca i-contrast agent ebizwa ngokuthi i-gadolinium futhi zivele zikhanya kakhulu ku-MRI.

Ukuskena kwe-MRI kuyindlela yobuchwepheshe bokuthwebula izithombe enembile kakhulu, ephumelelayo, futhi ephephile etholakalayo. Ngaphandle kwemisebe ye-ionizing, i-MRI ikhiqiza imiphumela enemininingwane eminingi futhi enembile. Nakuba i-MRI iphumelela kakhulu ekuthwebuleni izingxenye ezithile zomzimba njengomgogodla, isibindi, noma ubuchopho, ingaskena umzimba wonke ukuze ithole ama-anomalies angokomzimba, izimila ezisezingeni lazo lokuqala lokukhula, noma nje isithombe sempilo yomuntu iyonke.

I-MRI scan iyindlela ye-radiology engangenisi umswakama egwema ukusetshenziswa kwemisebe ye-x-ray. I-MRI scan ayinayo imiphumela emibi eyaziwayo. Izinzuzo ze-MRI scan zihlobene nokunemba kwayo ekuboneni ukukhubazeka kwesakhiwo emzimbeni.

I-MRI idala izithombe ezinemininingwane yezitho zomzimba nezinye izakhiwo zomzimba zangaphakathi.
