CT scan intloko; inkqubo nokubuyekezwa

Uxilongo enye kuphela isikhalazo lwezigulane uhlala akunakwenzeka, ingakumbi xa kukho iingxaki kunye luvo. Phanda imeko yakhe ivumela Itomography ngekhompyutha (Itomography) intloko. Le yenye yeendlela mihla ogulayo oko kumlungele na izigulane yeendidi yobudala ahlukeneyo.

inqubo Overview

Itomography ngekhompyutha iyindlela ukufunda iwonga kunye nolwakhiwo izibilini ngoncedo lwe-X-reyi. MRI inika umfanekiso kwizinga eliphezulu apho kusetyenzwa yi computer. Isiseko indlela ubugcisa X-ray are (Ukufikisa) kunye nokubhaliswa umfanekiso detectors ray hypersensitive (ukunciphisa isikalo radiation), kunye nokusebenza kunye nohlahlelo umfanekiso zifunyanwa ngokusebenzisa iinkqubo zekhompyutha.

Itomography ngekhompyutha (CT) yentloko unika umfanekiso opheleleyo imeko yengqondo, izicwili ezithambileyo, ithambo izakhiwo ezikufutshane. Le ndlela loxilongo isetyenziselwa ukuchonga ezimbi kweliso kunyango. A indlela ezinokuntsonkotha oluchanileyo nemagnethi livakale umfanekiso ukuxilonga nayiphi na impatho-luvo.

Iimpawu zibonisa ukuba ukusetyenziswa kwe entloko CT

Kodwa kude kube ngoku, i "isixhobo 'siphambili lokufunyaniswa karhulumente e-nervous system yaba ngehamile luvo okhethekileyo abahlola uvakalelo. Jonga kwakhona kwi ingxaki kwiingcaphephe akunakwenzeka. Ngelo xesha langoku uqwalasele icandelo lobuchopho Itomography ngekhompyutha ivumela. Nangona zalapho endala oogqirha zikhohlakele.

Yabela umfanekiso ubuchopho ungase iimpawu ezithile kunye nezikhalazo nomonde. Yayibubungqina ezingundoqo zokufumanis iimeko zophendlo lwezifo zezi zilandelayo:

• ikhanda kwenja;
• ukusola Oncology;
• ukuphatheka cranial;
• amane noxinzelelo intracranial;
• kobuchopho, meningitis;
• severe ubuchopho (stroke);
• CNS leengxaki embalini;
• ubukho namaqumrhu angaphandle.

Direction moshilongo kunganika neurosurgeon, luvo, otolaryngologist. Kwakhona specialist ingxelo sisigulane, nto leyo ezenza tomogram intloko. izixhobo Modern ngoku izixhobo namaziko zonyango abucala ezininzi kunye nezibhedlele.

Oko kubonisa scan intloko?

Ngexesha isifundo lihlaleni X-ray ngenxa site inyama intloko yakhe. Abenzi boluvo ibekwe ngaphakathi umatshini, imiqadi esisigxina iguqulwe, kunye nekhompyutha uqala ukuzilungisa ingcaciso efunyenweyo kwaye iyiguqule ibe umfanekiso. Kwi kwisiphumo se umfanekiso abamnyama nabamhlophe kungabonwa kwentlungu, nangezilonda, legazi, ukucacisa indawo yazo kunye nomlinganiselo.

Tomogram intloko ukuvavanya imeko engwevu umcimbi emhlophe, ventricles yobuchopho, amathambo yobuso nobuchopho isebe, imithambo yegazi, imithambo yegazi, sinuses.

Ngoncedo lwe umfanekiso kubaguli kwafunyaniswa ezimbi zilandelayo:

• thrombosis;
• kwemithambo;
• ukopha, stroke kobuchopho;
• cysts;
• iinkqubo esosulelayo;
• okungahambi bekhubazekile;
• ukuphatheka cranial;
• osteomyelitis;
• izilonda neoplastic.

Njani Itomography entloko?

Musa ukoyika yenkqubo - it is elula ngokupheleleyo. ufakelo ukuskena of kumbhobho zezindlu, nto leyo lingqongwe umazibuthe. Le isigulane ibekwe phezu kwetafile okhethekileyo utyhala (kwesingqengqelo), ngubani "kuza" ngaphakathi msele vuavanyisi xa iyasebenza. Yingcali ekwenzeni isifundo kufuneka kwigumbi elilandelayo nokulawula inkqubo loxilongo, imeko yesigulane.

Kwinkqubo loxilongo bahlala etafileni apho isigulane uyayijikeleza sentlalo. Ukusebenza, lo kwelicebo ungabangela ingxolo. Kubalulekile ukuba sihlale sizolile kwaye hayi ukuba, ukuze ufumane umfanekiso echanileyo. Ukuba kuyimfuneko, ingcali nga ukulungisa intloko yomguli ngayo iibhanti ezikhethekileyo ngexesha ukuskena.

Xa Akuvunyelwe ukwenza CT scan?

Ngokungafaniyo ngemagnethi livakale umfanekiso, CT unenani ukulinganiselwa. Akukho nkqubo lwenziwa izigulane ukuba ubunzima-150 kg. izixhobo umfanekiso Modern ayenzelwanga kuqhuba isaveyi ezi izigulane. Enye indlela kule meko MRI.

Ukuba isigulane unesifo bephelelwa, scan intloko mazenziwe kuphela phantsi Ukubulawa jikelele. Linembali inkqubo ukuphazamiseka kwengqondo ezinkulu akwenziwanga.

Contraindicated kwenkcazo umfanekiso abasetyhini abakhulelweyo. Ngexesha zisanyisa CT ukuze wenziwe, kodwa kwiintsuku ezilandelayo kufuneka uyeke ukuncancisa-ibele kunye nobisi nokubonisa.

Ngaba kunokwenzeka ukuba iqalise le nkqubo abantwana?

Siphethe umfanekiso izigulane abaselula kunokwenzeka, kodwa kuphela kukuswela ekhethekileyo. Kuba nomzimba lo mntwana radiation X-ray kuyingozi. Ngoko ke, i CT scan idla indawo umfanekiso livakale magnetic, apho radiation electromagnetic ezisetyenzisiweyo. Kunyaka wokuqala yobomi sana, xa fontanelle namanje evulekile, ukuphanda urhulumente ingqondo evumela le ndlela kokuxilongwa njengoko neurosonography.

Tomogram intloko linokukwenziwa kwi amatakane kwezi meko zilandelayo:

• unesifo yokuzalwa;
• noxinzelelo intracranial;
• hydrocephalus;
• ukungaqheleki semithambo, cysts;
• ukusola Oncology;
• abagula ngengqondo;
• ukulimala, nemivumbo, kwamathambo yaba lukakayi.

Indlela ukulungiselela umntwana wakho?

Yenza intloko tomogram lomntwana ngaphandle kokusebenzisa zomzimba okanye umthomalalisi akusoloko kusenzeka ngenxa iimpawu ubudala. Kids nzima ukubamba cwaka ngexesha mishini scan. Ukongeza, umntwana kuzoyika izandi, ephethe umatshini esebenzayo. Kungenxa yoko le nto, lenquba yenzelwa phantsi Ukubulawa jikelele. Imeko umntwana uya kulandela oogqirha kunye nogqirha.

Ukubulawa kwenza kuphela ungatyanga yaye, ke ngoko, isidlo yokugqibela umntwana kufuneka zingadlulanga iiyure ezi-4 phambi kokuba le nkqubo. Iintsana zingatya iiyure 2-3. Kwezinye iimeko, iingcali Siyaleza ukwenza umntwana electrocardiogram lokuqala. Ukuba kufuneka ulawulo Ngokwahlukileyo medium, ziyacelwa ukuba ukujonga uvakalelo usana ukuba ichiza.

Ukulungiselela abadala

Le ndlela diagnostic ayifuni uqeqesho olulodwa. Kwangoko phambi kokuba inkqubo isigulane kufuneka athathe off izinto zesinyithi, izacholo. Ukuba walumkisa malunga ubukho abaziingcali ukuxilongwa zalo. Akukho mfuneko Kwathi inkqubo kwi isisu ngokupheleleyo.

Ukuba isigulane iboniswa ubambe i Itomography Ubuchopho usebenzisa arhente koko, kumele isuswe isidlo iiyure 4-5 phambi scanning. Kungenjalo, kusenokuba isicaphucaphu, ukugabha, ukuba nesiyezi. Ukuba kuyimfuneko, isigulana unokuthabatha sine.

Ukusetyenziswa umahluko

Ukuba kuyimfuneko, umfanekiso enokwenziwa usebenzisa arhente umahluko ethile. Oku kukuvumela ukuba nomfanekiso kwiindawo ezininzi ezinzima yomkhondo ukuya kulimo X-ray. Ukucacisa inkqubo nendlela ukwenza tomogram lwentloko kunye umahluko? Okokuqala, le ndlela uphethwe kuyimfuneko ukuba izigulane kufuneka ukuba ukujonga imeko iimpahla. Colorant ikuvumela ukuba ufumane yayiliziko entsha ischemia kunye nomhlaza nangezilonda.

Phakathi ngosuku olunye emva kokuba iinkqubo arhente umahluko iya salawo aphumayo. Ngeli xesha, kubalulekile ukuba usele iziselo. Ukuze siphephe zisifake, bubulumko ukuba baye elebhu baphethwe wayesazi bayaliwa umahluko.

Izimo

Sebenzisa i-arhente umehluko ayivumelekanga kwi iziguli ubudala abaneminyaka engaphantsi kwe-14 ubudala kunye nabasetyhini abakhulelweyo. Izimo ubalisa ukusilela kwezintso, kukwalisa ubukho ayodini, isifo lengqula, wegazi.

Kuphela emva banokubekwa lokuphelisa nya zonke Izimo CT scan intloko. Kufuneka kuqondwe ukuba indlela njengenye yezona ulwazi, kwaye ke ngoko abavumi isifo ngaphandle kwesizathu elungileyo, oogqirha musa singacebisi kakhulu. Le nkqubo inceda kwi zigaba okuqala ukuchonga isifo kwaye uqale unyango ngexesha elililo.

Tomogram intloko: inkcazo iziphumo

Ukungafihli yoko, iingcali kungathatha ixesha. Ngokuqhelekileyo imifanekiso zinikwa isigulana ngemizuzu 30-60 emva uxilongo, kodwa kwezinye iimeko kufuneka ulinde ixesha elide. Kwelinye icala isigulane ifumana Iifoto ezimnyama-mhlophe, kukho CD kunye ukurekhodwa kunye nenkcazelo scan data.

Iimpendulo kufuneka udibane nogqirha, owasinikayo ulwalathiso wawo ukuya kuvala ingxingwa Itomography yentloko. Kwixesha elizayo kusenokufuneka babonane ezinye iingcali.

Ixabiso kunye nohlaziyo

Ngokutsho iingcali, intloko Itomography umonakalo zexabiso ukuze umzimba womntu ayikasebenzi, ukuba uphando lwenziwa kwi izixhobo ezitsha. Ithamo avareji ngeseshoni enye ngu 6 m3v. Ukuphanda ngemeko yaba lukakayi, nengqondo radiation ayidluli 2 m3v.

Izigulane bayacetyiswa ukuba zincede zikhethe multislice umfanekiso, nto leyo kwixesha elifutshane (a imizuzwana embalwa) ukusebenza inani elikhulu inezilayo kwaye ukuthwala umthwalo liphantsi radiation. ixabiso Unyango kudla ixhomekeke nezixhobo kwaye kuluhlu-3 000-5 000. Ukuba kuyimfuneko, sebenzisa i-arhente ixabiso inkqubo umahluko liya kwanda ukuya ku-7 000-12 000.

izigulane ezininzi ziya kuqalisa namava, ukuze bafunde ukuba unikwe CT scan lwentloko. Izimvo inkqubo kuqinisekisa uloyiko lwabo, kwaye izigulane aqalile ukwala ukuba baye kuhlola. Enyanisweni, oku kwenyusa kuphela meko. isigulo kwangethuba kuvumela ixesha ukubona ezibangelwa incinane luvo kunye nokuqaliswa unyango. Ungakhathazeki malunga radiation kuba ithamo ziya kuba ncinci kwaye akayi kakubi impilo.
