Yintoni i-cranial CT scan?

Iskena se-cranial CT sisixhobo sokuchonga esisetyenziselwa ukwenza imifanekiso eneenkcukacha ngaphakathi kwentloko yakho, njengekrele lakho, ingqondo, iisono zeparanasal, ii-ventricles kunye neziseko zamehlo. I-CT imele i-computed tomography, kwaye olu hlobo lokuskena lukwabizwa ngokuba yi-CAT scan. Iskena se-cranial CT saziwa ngamagama ahlukeneyo ngokunjalo, kubandakanya ukuskena kwengqondo, ukuskena kwentloko, ukuskena ukakayi, kunye nesynus scan.

Le nkqubo ayisebenzi, oko kuthetha ukuba ayifuni kutyando. Kuhlala kucetyiswa ukuba kwenziwe uphando ngeempawu ezahlukeneyo ezibandakanya inkqubo yeemvakalelo ngaphambi kokuba ujike kwiinkqubo ezingenayo.

Izizathu zesikena se-cranial CT

Imifanekiso eyenziwe yi-cranial CT scan ineenkcukacha ngakumbi kuneeX-reyi eziqhelekileyo. Banokunceda ekuchongeni uluhlu lweemeko, kubandakanya:

• ukungaqheleki kwamathambo okakayi lwakho
• i-arteriovenous malformation, okanye imithambo yegazi engaqhelekanga
• atrophy yethishu yobuchopho
• iziphene zokuzalwa
• I-aneurysm yengqondo
• Ukopha, okanye ukopha engqondweni yakho
• i-hydrocephalus, okanye i-fluid buildup kwikhakhayi lakho
• usulelo okanye ukudumba
• ukwenzakala entlokweni, ebusweni, okanye kulukakayi
• ukubetha
• amathumba

Ugqirha wakho unokuyalela i-cranial CT scan ukuba wenzakele okanye ubonise naziphi na kwezi mpawu ngaphandle kwesizathu:

• isiqaqa
• intloko ebuhlungu
• ukuxhuzula, ngakumbi ukuba ikho oku kwenzekileyo kutshanje
• utshintsho olukhawulezileyo lokuziphatha okanye utshintsho kwindlela ocinga ngayo
• ukungeva kakuhle
• ukulahleka kombono
• ubuthathaka bemisipha okanye ukuba ndindisholo nokubetha
• kunzima ukuthetha
• kunzima ukugwinya

I-cranial CT scan inokusetyenziselwa ukukhokela ezinye iinkqubo ezinje ngokuhlinzwa okanye i-biopsy.

Kwenzeka ntoni ngexesha le-cranial CT scan

Iskena se-cranial CT sithatha uthotho lwe-X-ray. Ikhompyuter emva koko ibeka le mifanekiso yeX-reyi kunye ukwenza imifanekiso eneenkcukacha zentloko yakho. Le mifanekiso inceda ugqirha wakho ukuba enze isifo.

Inkqubo ihlala isenziwa esibhedlele okanye kwiziko lokucinga labangaphandle. Kuya kuthatha kuphela imizuzu eli-15 ukugqiba ukuskena.

Ngomhla wenkqubo, kufuneka ususe ubucwebe kunye nezinye izinto zesinyithi. Banokonakalisa iskena kwaye baphazamise ii-X-ray.

Ngokuqinisekileyo uya kucelwa ukuba utshintshe ibe yingubo yasesibhedlele. Uya kulala kwitafile emxinwa nokuba ujonge phezulu okanye ujonge phantsi, kuxhomekeke kwizizathu ze-CT scan yakho.

Kubaluleke kakhulu ukuba uhlale uzolile ngokupheleleyo ngexesha loviwo. Nokuba intshukumo encinci inokuyiphazamisa imifanekiso.

Abanye abantu bafumana iskena se-CT sixinzelele okanye si-claustrophobic. Ugqirha wakho unokucebisa ukuba uthomalalise ukuze uhlale uzolile ngexesha lenkqubo. Ukuthomalalisa kuya kukunceda uhlale uthe cwaka. Ukuba umntwana wakho une-CT scan, ugqirha wabo unokuncomela ukuthambisa ngenxa yezi zizathu.

Itafile ityibilika kancinci ukuze intloko ibe ngaphakathi kwiskena. Unokucelwa ukuba ubambe umphefumlo wakho ixesha elifutshane.I-ray ye-X-ray ye-scanner iya kujikeleza intloko yakho, idale uluhlu lweemifanekiso zentloko yakho kwii-angles ezahlukeneyo. Imifanekiso nganye ibizwa ngokuba zizilayi. Ukugcwala izilayi kudala imifanekiso emacala mithathu.

Imifanekiso inokubonwa kwangoko kwimonitha. Ziza kugcinwa ukuze zibonwe kamva kwaye ziprintwe. Ukhuseleko lwakho, isithwebuli se-CT sinemakrofoni kunye nezithethi zonxibelelwano ngeendlela ezimbini kunye nesixhobo sokuskena.

Umahluko wokwahlula idayi kunye ne-cranial CT scan

Idayi yokwahlula inceda ukuqaqambisa ezinye iindawo ngcono kwimifanekiso ye-CT. Umzekelo, inokuqaqambisa kwaye igxininise imithambo yegazi, amathumbu, kunye nezinye iindawo. Idayi inikwa ngomgca ofakwa ngaphakathi kufakwa emthanjeni wengalo okanye yesandla sakho.

Rhoqo, imifanekiso iqala ithathwe ngaphandle kokuthelekisa, kwaye emva koko iphindwe ngokuchaseneyo. Nangona kunjalo, ukusetyenziswa kwedayi yokungafani akusoloko kuyimfuneko. Kuxhomekeka kwinto efunwa ngugqirha wakho.

Ugqirha wakho unokukuyalela ukuba ungatyi okanye usele iiyure ezininzi ngaphambi kovavanyo ukuba uza kufumana idayi eyahlukileyo. Oku kuxhomekeke kwimeko ethile yonyango. Buza ugqirha wakho ngemiyalelo ethile ye-CT scan yakho.

Ukulungiselela kunye nezilumkiso zokuthathelwa ingqalelo

Itheyibhile yesikena imxinwa kakhulu. Buza ukuba ngaba kukho umda wobunzima kwitafile yeskena se-CT ukuba unobunzima obungaphezulu kweepawundi ezingama-300.

Qiniseka ukuba uxelela ugqirha wakho ukuba ukhulelwe. I-ray-ray nayiphi na uhlobo ayikhuthazwa kubafazi abakhulelweyo.

Uya kufuna ukuba uqaphele ezinye iindlela zokuzikhusela ukuba kuya kusetyenziswa idayi eyahlukileyo. Umzekelo, kufuneka kuthathwe amanyathelo akhethekileyo kubantu abakwisifo seswekile i-metformin (Glucophage). Qiniseka ukuba wazise ugqirha wakho ukuba uthatha eli chiza. Kananjalo xelela ugqirha wakho ukuba ukhe wehlelwa yinto engalunganga xa uthelekisa idayi.

Iziphumo ebezingalindelekanga ezinokwenzeka okanye umngcipheko

Iziphumo ebezingalindelekanga kunye nemingcipheko yokuvavanywa kwe-cranial CT kubandakanya ukungonwabi, ukubonakaliswa yimitha, kunye nokusabela okuchaseneyo nedayi eyahlukileyo.

Xoxa ngayo nayiphi na inkxalabo nogqirha wakho phambi kovavanyo ukuze uvavanye ubungozi kunye nezibonelelo ezinokubakho kwimeko yakho yonyango.

Ukungakhululeki

Iskena se-CT ngokwaso yinkqubo engenazintlungu. Abanye abantu baziva bengakhululekanga kwitafile enzima okanye kunzima ukuhlala bethe cwaka.

Unokuziva usitsha kancinci xa idayi eyahlukileyo ingena emithanjeni yakho. Abanye abantu bafumana incasa yesinyithi emilonyeni yabo kunye nemvakalelo efudumeleyo kuyo yonke imizimba yabo. Ezi mpendulo ziqhelekile kwaye zihlala zihlala ngaphantsi komzuzu.

Ukuvezwa kwemitha

Ukuskena kwe-CT kukuchaya kwimitha ethile. Oogqirha ngokubanzi bayavuma ukuba umngcipheko usezantsi xa kuthelekiswa nomngcipheko wokungafumaneki unengxaki yempilo. Umngcipheko ovela kwiskena esinye uncinci, kodwa uyonyuka ukuba une-X-ray ezininzi okanye i-CT scans ekuhambeni kwexesha. Iiskena esitsha sinokukuveza kwimitha engaphantsi kuneemodeli ezindala.

Tshela ugqirha wakho ukuba ukhulelwe. Ugqirha wakho unokukwazi ukunqanda ukuveza umntwana wakho kwimitha ngokusebenzisa ezinye iimvavanyo. Oku kunokubandakanya ukuskena kwentloko ye-MRI okanye i-ultrasound, engasebenzisi radiation.

Ukuphendula ngokuchaseneyo nokwaliwa

Xelela ugqirha wakho phambi kokuskena ukuba ngaba wakha wakufumana ukungahambelani nedayi eyahlukileyo.

Idayi yokungafaniyo ihlala iqulethe iodine kwaye inokubangela isicaphucaphu, ukugabha, irhashalala, urhashalala, ukurhawuzelela, okanye ukuthimla kubantu abangadibaniyo ne-iodine. Unokunikwa i-steroids okanye i-antihistamines ukunceda kwezi mpawu ngaphambi kokuba ufumane inaliti yedayi. emva kovavanyo, kusenokufuneka usele iziselo ezingaphezulu ukunceda ukugungxula iodine emzimbeni ukuba unesifo seswekile okanye isifo sezintso.

Kwiimeko ezinqabileyo kakhulu, ukungafani kwedayi kunokubangela i-anaphylaxis, umzimba wonke ophendulayo ongasongela ubomi. Yazisa umsebenzisi weskena ngokukhawuleza ukuba unengxaki yokuphefumla.

Iziphumo ze-cranial CT scan kunye nokulandela

Kuya kufuneka ukwazi ukubuyela kwisiqhelo sakho emva kovavanyo. Ugqirha wakho unokukunika imiyalelo ekhethekileyo ukuba umahluko wasetyenziswa kuvavanyo lwakho.

Ingcali ye-radiologist iyakutolika iziphumo zovavanyo kwaye ithumele ingxelo kugqirha wakho. Izikena zigcinwa kubuchwephesha ukuze zisetyenziswe kwixesha elizayo.

Ugqirha wakho uya kuxoxa nawe ngengxelo yereyikhrayoloji. Kuxhomekeke kwiziphumo, ugqirha wakho unoku-odola uvavanyo ngakumbi. Okanye ukuba bayakwazi ukufikelela kuvavanyo, baya kuhamba namanyathelo alandelayo nawe, ukuba akhona.
