Isinus MRI scan

Ukuvavanywa kwe-imaging resonance imaging (MRI) yesono kudala imifanekiso eneenkcukacha ngeendawo ezizaliswe ngumoya ngaphakathi kokhakhayi.

Ezi zithuba zibizwa ngokuba ziisono. Uvavanyo alusebenzi.

I-MRI isebenzisa iimagnethi ezinamandla kunye namaza erediyo endaweni yemitha. Iimpawu ezivela kumandla kazibuthe ziyaxhuma emzimbeni wakho kwaye zithunyelwa kwikhompyuter. Apho, ajikwa aba yimifanekiso. Iindidi ezahlukeneyo zethishu zibuyisela umva imiqondiso eyahlukeneyo.

Imifanekiso enye ye-MRI ibizwa ngokuba zizilayi. Imifanekiso inokugcinwa kwikhompyuter okanye iprintwe kwifilimu. Olunye uvavanyo luvelisa uninzi okanye ngamanye amaxesha amakhulu emifanekiso.

Unokucelwa ukuba unxibe ilokhwe yasesibhedlele okanye impahla ngaphandle kweentsimbi okanye iziphu (ezinje ngezikipa kunye nesikipa). Iindidi ezithile zentsimbi zinokubangela imifanekiso engacacanga.

Uya kulala kwitafile emxinwa, ethi ityibilike kwiskena esimile okwe tonela.

Izixhobo ezincinci, ezibizwa ngokuba ziikhoyili, zibekwe zijikeleze intloko. Ezi zixhobo zinceda ukuphucula umgangatho wemifanekiso.

Ezinye iimviwo zifuna idayi ekhethekileyo (umahluko). Idayi ihlala inikwa ngaphambi kovavanyo kusetyenziswa umthambo (IV) esandleni okanye kwingalo yakho. Idayi inceda i-radiologist ibone iindawo ezithile ngokucacileyo.

Ngexesha le-MRI, umntu osebenza kumatshini uya kukujonga ukwelinye igumbi. Uvavanyo luhlala luhlala imizuzu engama-30, kodwa lungathatha ixesha elide.

Ngaphambi kovavanyo, xelela i-radiologist ukuba uneengxaki zezintso. Oku kunokuchaphazela ukuba ngaba unokwahluka kwe-IV.

Ukuba woyika indawo ezivalelweyo (une-claustrophobia), xelela umboneleli wakho wezempilo ngaphambi koviwo. Unokunikwa iyeza lokukunceda uzive usozela kwaye ungakhathazeki kangako. Umboneleli wakho unokucebisa "nge-MRI" evulekileyo, apho umatshini ungekho kufutshane nomzimba.

Iindawo ezinamandla zemagneti ezenziweyo ngexesha le-MRI zinokuphazamisa i-pacemaker kunye nezinye izinto ezifakwayo. Abantu abanezinto ezininzi zentliziyo abanakho ukuba ne-MRI kwaye akufuneki bangene kwindawo ye-MRI. Abanye abenza iicememaker ezintsha bakhuselekile ngeMRI. Uya kudinga ukuqinisekisa nomboneleli wakho ukuba ngaba umenzi wenhliziyo ukhuselekile kwi-MRI.

Awunakho ukuba neMRI ukuba unayo nayiphi na kwezi zinto zentsimbi emzimbeni wakho:

• Iiklip ze-aneurysm zengqondo
• Iindidi ezithile zezivalo zentliziyo ezingezizo
• Intliziyo defibrillator okanye ipacemaker
• Ukufakwa kwendlebe ngaphakathi (cochlear)
• Kutshanje kubekwe amalungu anganyanisekanga
• Iindidi ezithile ze-vascular stents
• Iimpompo zentlungu

Xelela umboneleli wakho ukuba unayo enye yezi zixhobo xa ucwangcisa uvavanyo, ukuze kuchongwe kanye uhlobo lwesinyithi.

Phambi kweMRI, abasebenzi bentsimbi okanye abantu abanokuthi bavezwe iziqwenga zentsimbi kufuneka bafumane i-x-ray yekhakhayi. Oku kukujonga isinyithi emehlweni.

Kuba iMRI inemagnethi, izinto ezinesinyithi ezinje ngeepeni, iipokotho, kunye neiglasi zamehlo zingabhabha ngaphaya kwegumbi. Oku kunokuba yingozi, ke abavumelekanga kwindawo yeskena.

Ezinye izinto zentsimbi nazo azivunyelwe egumbini:

• Izinto ezinje ngezacholo, iiwotshi, amakhadi etyala kunye nezinto zokuva zinokonakaliswa.
• Izikhonkwane, izikhonkwane zeenwele, iiziphu zentsimbi, kunye nezinto ezifanayo zesinyithi zinokuyigqwetha imifanekiso.
• Umsebenzi osuswayo wamazinyo kufuneka ukhutshwe ngaphambi nje kokuskena.

Uvavanyo lwe-MRI alubangeli zintlungu. Abanye abantu banokuba nexhala ngaphakathi kwiskena. Ukuba uneengxaki zokulala ungazolanga okanye usoyika kakhulu, unganikwa iyeza lokukunceda uzive uzolile (uthomalalisa). Ukuhamba kakhulu kunokuphazamisa imifanekiso ye-MRI kwaye kubangele iimpazamo.

Itafile inokuba nzima okanye ibanda. Ungacela ingubo okanye umqamelo. Umatshini uvelisa ingxolo enkulu kunye nengxolo xa kuvuliwe. Unganxiba iiplagi zendlebe ukunceda ukunciphisa ingxolo.

I-intercom egumbini ikuvumela ukuba uthethe nomntu osebenza iskena ngalo naliphi na ixesha. Ezinye ii-MRI scanner zinomabonakude kunye nee-headphone ezikhethekileyo zokunceda ixesha lidlule.

Akukho xesha lokubuyisela, ngaphandle kokuba ufuna ukuthomalalisa. Emva kokuvavanywa kweMRI, ungabuyela emva kwindlela oqhelekileyo yokutya, umsebenzi, kunye namayeza.

Olu vavanyo lubonelela ngemifanekiso eneenkcukacha zesono. Umboneleli wakho unoku-odola olu vavanyo ukuba unayo:

• Umsele ongaqhelekanga wempumlo
• Ukufumana okungaqhelekanga kwi-x-ray okanye kwi-endoscopy yempumlo
• Isiphene sokuzalwa sezono
• Ukuphulukana nevumba
• Ukuvaleka kwendlela yempumlo engangcono ngonyango
• Iimpumlo zegazi eziphindaphindiweyo (epistaxis)
• Iimpawu zokulimala kwindawo yesono
• Iintloko ezingachazwanga
• Iintlungu zesono ezingachazekiyo ezingangcono kunyango

Umboneleli wakho unokuyalela olu vavanyo ukuba:

• Qinisekisa ukuba iipolyps zempumlo zisasazekile ngaphaya kwempumlo
• Vavanya usulelo okanye ithumba
• Chonga ubunzima okanye ithumba, kubandakanya umhlaza
• Cwangcisa utyando lwesono okanye ujonge inkqubela yakho emva kotyando

Iziphumo zithathwa njengeziqhelekileyo ukuba amalungu kunye nolwakhiwo oluvavanywayo luqhelekile kwinkangeleko.

Iindidi ezahlukeneyo zezicubu zibuyisela umva imiqondiso eyahlukeneyo ye-MRI. Izicubu ezisempilweni ziya kuthumela umqondiso owahluke kancinci kunezicubu zomhlaza.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Umhlaza okanye ithumba
• Usulelo kumathambo ezono (i-osteomyelitis)
• Usulelo lwezicubu ezijikeleze iliso (i-orbital cellulitis)
• Iipolyps zempumlo
• Sinusitis - etsolo
• Sinusitis - ezingapheliyo

Thetha nomboneleli wakho ukuba unemibuzo kunye neenkxalabo.

I-MRI ayisebenzisi radiation. Akukho ziphumo zibi zichazwe kwi-MRI. Uhlobo oluqhelekileyo lokuchasana (idayi) elisetyenzisiweyo yi-gadolinium. Kukhuselekile kakhulu. Ukungaphenduli komzimba kule dayi kunqabile ukuba kwenzeke. Umntu osebenza kumatshini uya kujonga ukubetha kwentliziyo yakho nokuphefumla kwakho.

Kunqabile kakhulu, abantu ukusilela kwezintso okanye isifo sesifo sezintso esinganyangekiyo banokuphucula ukusabela kwabo ngokungafaniyo kwidayi. Ukuba unengxaki yezintso, kubalulekile ukuba uxelele itekhnoloji ye-MRI kunye nomboneleli wakho ngaphambi kokuba ufumane le dayi.

I-MRI ihlala ingacetyiswa kwiimeko ezibi kakhulu, kuba izixhobo nezixhobo ezixhasa ubomi azinakungena kwindawo ekhuselekileyo kwaye uvavanyo lunokuthatha ixesha elininzi.

Abantu baye benzakala koomatshini be-MRI xa bengazisusanga izinto zesinyithi ezingubeni zabo okanye xa izinto zesinyithi zishiywe egumbini ngabanye.

Uvavanyo olunokwenziwa endaweni ye-MRI yesono kubandakanya:

• Ukuvavanywa kwe-CT kwezono
• X-reyi le sinuses

Iskena se-CT sinokuthandeka kwiimeko zongxamiseko, kuba iyakhawuleza kwaye ihlala ifumaneka kwigumbi likaxakeka.

Phawula: I-MRI ayisebenzi njenge-CT ekuchazeni i-anatomy ye-sinus, kwaye ke ayisetyenziselwa ukuqhelisela i-sinusitis ebukhali.
