Ukuskena kwe-Sinus MRI

Ukuskena kwe-magnetic resonance imaging (MRI) kwezono kudala izithombe eziningiliziwe zezikhala ezigcwaliswe umoya ngaphakathi kogebhezi.

Lezi zikhala zibizwa ngokuthi ama-sinus. Ukuhlolwa akudluli.

I-MRI isebenzisa ozibuthe abanamandla namagagasi omsakazo esikhundleni semisebe. Izimpawu ezisuka kumandla kazibuthe ziyaqhuma emzimbeni wakho bese zithunyelwa kukhompyutha. Lapho, ziphenduka izithombe. Izinhlobo ezahlukahlukene zezicubu zibuyisa amasignali ahlukile.

Izithombe ezi-Single ze-MRI zibizwa ngokuthi izingcezu. Izithombe zingagcinwa kukhompyutha noma ziphrintwe kwifilimu. Isivivinyo esisodwa sikhiqiza inqwaba noma kwesinye isikhathi amakhulu ezithombe.

Ungacelwa ukuthi ugqoke ingubo yasesibhedlela noma okokwembatha ngaphandle kwezicucu zensimbi noma uziphu (njengezikibha zezithukuthuku nesikibha). Izinhlobo ezithile zensimbi zingadala izithombe ezifiphele.

Uzolala etafuleni elincane, elingena kuskena esimise okomhubhe.

Amadivayisi amancane, abizwa ngokuthi amakhoyili, abekwa azungeze ikhanda. Lawa madivayisi asiza ukuthuthukisa ikhwalithi yezithombe.

Ezinye izivivinyo zidinga udayi okhethekile (umehluko). Idayi ivame ukunikezwa ngaphambi kokuhlolwa ngomthambo (IV) osesandleni sakho noma engalweni. Idayi isiza udokotela we-radiologist ukuthi abone izindawo ezithile ngokucace kakhudlwana.

Ngesikhathi seMRI, umuntu osebenzisa umshini uzokubuka ukwelinye igumbi. Ukuhlolwa kuvame ukuthatha imizuzu engama-30, kepha kungathatha isikhathi eside.

Ngaphambi kokuhlolwa, tshela i-radiologist uma unezinkinga zezinso. Lokhu kungathinta ukuthi ungaba nokungafani kwe-IV.

Uma wesaba izikhala ezivalekile (une-claustrophobia), tshela umhlinzeki wakho wezokunakekelwa kwempilo ngaphambi kokuhlolwa. Unganikezwa umuthi ozokusiza uzizwe ulele futhi ungakhathazeki kangako. Umhlinzeki wakho futhi angancoma i-MRI "evulekile", lapho umshini ungasondelene kakhulu nomzimba.

Amandla kazibuthe aqinile adalwe ngesikhathi seMRI angaphazamisa ama-pacemaker nezinye izinto ezifakiwe. Abantu abanezinhliziyo eziningi zenhliziyo abakwazi ukuba ne-MRI futhi akufanele bangene endaweni ye-MRI. Amanye ama-pacemaker amasha enziwe aphephile nge-MRI. Uzodinga ukuqinisekisa nomhlinzeki wakho uma ngabe i-pacemaker yakho iphephile kwi-MRI.

Ungahle ungakwazi ukuba ne-MRI uma unezinto zensimbi ezilandelayo emzimbeni wakho:

• Iziqeshana ze-aneurysm zobuchopho
• Izinhlobo ezithile zamavalvu enhliziyo yokufakelwa
• Inhliziyo defibrillator noma i-pacemaker
• Ukufakwa kwendlebe kwangaphakathi (cochlear)
• Amalunga wokufakelwa asanda kufakwa
• Izinhlobo ezithile ze-vascular stents
• Amaphampu ezinhlungu

Tshela umhlinzeki wakho uma unenye yalawa madivayisi lapho uhlela ukuhlolwa, ngakho-ke kunganqunywa uhlobo lwensimbi ngqo.

Ngaphambi kwe-MRI, abasebenzi bensimbi noma abantu okungenzeka ukuthi bavezwe izingcezu zensimbi ezincane kufanele bathole i-x-ray yogebhezi. Lokhu ukuhlola insimbi emehlweni.

Ngoba i-MRI iqukethe uzibuthe, izinto eziqukethe izinsimbi ezifana nezibaya, ama-pocketknives, kanye nezibuko zamehlo zingandiza zinqamule igumbi. Lokhu kungaba yingozi, ngakho-ke abavunyelwe ukungena endaweni yesithwebuli.

Ezinye izinto zensimbi nazo azivunyelwe ukungena egumbini:

• Izinto ezinjengobucwebe, amawashi, amakhadi esikweletu nezinsiza-kuzwa zingalimala.
• Izikhonkwane, okokufaka izinwele, uziphu wensimbi, nezinto ezifanayo zensimbi kungasonta izithombe.
• Umsebenzi wamazinyo osusekayo kufanele ukhishwe ngaphambi nje kokuskena.

Ukuhlolwa kwe-MRI akubangeli buhlungu. Abanye abantu bangakhathazeka ngaphakathi kwesithwebuli. Uma unezinkinga zokulala unganyakazi noma unovalo kakhulu, unganikezwa umuthi ozokusiza uzizwe uzolile. Ukunyakaza okuningi kungafiphaza izithombe ze-MRI futhi kudale amaphutha.

Itafula lingaba nzima noma libande. Ungacela ingubo noma umcamelo. Umshini ukhiqiza imisindo emikhulu yokuqhuma nokuhayiza lapho uvuliwe. Ungafaka ama-plugs endlebe ukusiza ukunciphisa umsindo.

I-intercom egumbini ikuvumela ukuthi ukhulume nomuntu osebenzisa isithwebuli nganoma yisiphi isikhathi. Ezinye izikena ze-MRI zinamathelevishini namahedfoni akhethekile okusiza isikhathi sidlule.

Asikho isikhathi sokutakula, ngaphandle kokuthi udinga ukuthambisa. Ngemuva kokuskena kwe-MRI, ungabuyela emuva ekudleni okujwayelekile, emsebenzini, nasemithini.

Lokhu kuhlolwa kunikeza izithombe eziningiliziwe zezono. Umhlinzeki wakho anga-oda lokhu kuhlolwa uma une:

• Ukugeleza kwamanzi okungavamile
• Ukutholwa okungajwayelekile ku-x-ray noma nge-endoscopy yamakhala
• Ukukhubazeka kokuzalwa kwezono
• Ukulahlekelwa iphunga
• Ukuvaleka kwe-Nasal air okungabi ngcono ngokwelashwa
• Amakhala anegazi aphindaphindiwe (i-epistaxis)
• Izimpawu zokulimala endaweni yesinus
• Ukuphathwa ikhanda okungachazeki
• Ubuhlungu besono obungachazeki obungabi ngcono ngokwelashwa

Umhlinzeki wakho futhi anga-oda lokhu kuhlolwa ku:

• Thola ukuthi ama-polyps acinene asakaze ngale kwendawo yamakhala
• Linganisa ukutheleleka noma ithumba
• Thola isisindo noma isimila, kufaka phakathi umdlavuza
• Hlela ukuhlinzwa kwesono noma uqaphele intuthuko yakho ngemuva kokuhlinzwa

Imiphumela ibhekwa njengejwayelekile uma izitho nezinhlaka ezihloliswayo zibukeka ngendlela ejwayelekile.

Izinhlobo ezahlukahlukene zezicubu zithumela emuva amasiginali we-MRI ahlukile. Izicubu ezinempilo zizobuyisa isignali ehluke kancane kunezicubu zomdlavuza.

Imiphumela engajwayelekile ingabangelwa:

• Umdlavuza noma isimila
• Ukutheleleka emathanjeni ezono (i-osteomyelitis)
• Ukutheleleka kwezicubu ezizungeze iso (i-orbital cellulitis)
• Polyp acinene
• Sinusitis - oyingozi
• Sinusitis - okungamahlalakhona

Khuluma nomhlinzeki wakho uma unemibuzo nokukhathazeka.

I-MRI ayisebenzisi imisebe ye-ionizing. Ayikho imiphumela emibi ebikwe yi-MRI. Uhlobo oluvame kakhulu lokuqhathanisa (udayi) olusetshenzisiwe yi-gadolinium. Kuphephe kakhulu. Ukusabela okweqile kulo dayi akuvamile ukuba kwenzeke. Umuntu osebenzisa umshini uzoqapha ukushaya kwenhliziyo yakho nokuphefumula kwakho.

Kuyaqabukela kakhulu, abantu abanenkinga yezinso noma isifo esingapheliyo sezinso bangakhuphula ukusabela okunamandla kokungafani (kudayi). Uma unezinkinga zezinso, kubalulekile ukutshela uchwepheshe we-MRI nomhlinzeki wakho ngaphambi kokuthola lo dayi.

I-MRI imvamisa ayinconywa ezimeni ezinzima zokuhlukumezeka, ngoba imishini yokudonsa kanye neyokusekela impilo ayikwazi ukungena ngokuphepha endaweni yesithwebuli futhi ukuhlolwa kungathatha isikhathi esithile.

Abantu baye balinyazwa emishinini ye-MRI lapho bengasusi izinto zensimbi ezingutsheni zabo noma lapho izinto zensimbi zishiywa egumbini ngabanye.

Ukuhlolwa okungenziwa esikhundleni se-MRI yesono kufaka:

• Ukuhlolwa kwe-CT kwezono
• I-X-ray yezono

Kungancanyelwa i-CT scan ezimweni eziphuthumayo, ngoba iyashesha futhi ivame ukutholakala egumbini labezimo eziphuthumayo.

Qaphela: I-MRI ayisebenzi kangako njenge-CT ekuchazeni ukwakheka kwezono, ngakho-ke ayijwayele ukusetshenziselwa i-sinusitis esolisayo esolwayo.
