I-CT scan ikhanda: inqubo Izibuyekezo

Isiphetho sokuthi umuntu uphethwe elilodwa kuphela isikhalazo iziguli akwenzeki ngaso sonke isikhathi, ikakhulukazi uma kukhona izinkinga kanye isimiso sezinzwa. Phenya isimo sakhe ivumela tomography esebenza nge-computer ikhanda (tomography). Lona omunye yezindlela zesimanje ukuhlolwa ngokwelashwa ukuthi kufanelekile iziguli lwezigaba zobudala obuhlukene.

inqubo Uhlolojikelele

computed tomography iyindlela ukutadisha isimo kanye nesakhiwo izibilini ngosizo X-ray. MRI ihlinzeka high quality umfanekiso okuyinto kusetshenzwe nge-computer. Ngesisekelo indlela-X-ray ubuchwepheshe kukhona (Bokuhlela) kanye nokubhaliswa image ray hypersensitive imitshina (ukunciphisa umthamo ngemisebe), kanye kusebenziswe futhi kuhlaziywe yesithombe etholwe esebenzisa izinhlelo ze-computer.

tomography ngekhompyutha (CT) ikhanda kunikeza isithombe esiphelele isimo ingqondo, izicubu ezithambile, ithambo izakhiwo eduze. Lokhu indlela uphethwe usetshenziselwa ukukhomba pathologies kanye nokuqapha ukwelashwa kwazo. Indlela eziyinkimbinkimbi nezinzima bulunge-magnetic resonance imaging ukuxilonga yikuphi ukwephula isimiso sezinzwa.

Izinkomba ngokusetshenziswa ikhanda CT

Nokho kuze muva nje, "isikhali" esiyinhloko sitholakele isimo isimiso sezinzwa kwaba isando wezinzwa ekhethekile abahlola ukuzwela. Bheka futhi inkinga kusukela ochwepheshe kwakungenakwenzeka. Ngaleso sikhathi samanje ukuba sicabangele izingxenye zobuchopho tomography ngekhompyutha ivumela. Nakuba izinto zalapho ubudala odokotela ayisheshi.

Yabela ubuchopho may imaging e izimpawu ezithile kanye nezikhalo nesineke. I izinkomba main ekuxilongeni izimo zokucabanga okubangelwa isifo zimi kanje:

• bekhanda kwenja;
• izinsolo of Oncology;
• ukuhlukumezeka cranial;
• ngezikhathi waqinisa intracranial;
• encephalitis, meningitis;
• ukopha ebuchosheni (stroke);
• CNS zokugula emlandweni;
• khona imizimba angaphandle.

Direction ngoba uphethwe anganika udokotela ohlinza izinzwa, udokotela wezinzwa, Otolaryngologist. Futhi Uchwepheshe kubika yisiguli, lapho nenze ikhanda tomogram. imishini yesimanje manje ifakwe izikhungo eziningi yangasese sezokwelapha nasezibhedlela.

Lokho kukhombisa scan ikhanda?

Phakathi nesifundo X-ray abonise idlule yombambiqhaza izicubu indawo. Izinzwa elise ngaphakathi emshinini, modified imishayo fixed, nekhompyutha iqala sicubungula ulwazi wathola futhi oguqula bayifaka isithombe. On the okuholela isithombe omnyama nomhlophe kungenziwa umuntu elimele, izimila, ukopha itholiwe, ukucacisa indawo yabo futhi izinhlangothi.

Tomogram ikhanda ukuhlola isimo grey futhi ndaba ezimhlophe, ventricles zobuchopho, uMnyango amathambo ebusweni kanye ubuchopho, imithambo yegazi, imithambo yegazi, sinuses.

Ngosizo imaging ezigulini kutholakala ukuthi uphethwe yini pathologies ezilandelayo:

• thrombosis;
• useshonile;
• oluhambisana, unhlangothi ischemic;
• izinhlumba;
• izinqubo samafayela;
• anomalies azalwa naso;
• ukuhlukumezeka cranial;
• osteomyelitis;
• izilonda neoplastic.

kanjani tomography ikhanda?

Ungesabi inqubo - kuba kobuhlungu ngokuphelele. Iskena ukufakwa ngamapayipi cylindrical, okuyinto lizungezwe odonsa. Isiguli ibekwe etafuleni ekhethekile ngokuhambisa (kusofa), ngubani "iza" ngaphakathi Umhubhe isithwebuli lapho isebenze. Lo chwepheshe ofeza ukutadisha kufanele kuze ekamelweni olandelayo futhi ulawule inqubo ukuxilongwa, isimo lesiguli.

Ngo inqubo ukuxilongwa abazungeze itafula lapho isiguli uzungeza kulungiselelwa. Ngo ukusebenza, idivayisi kungadala umsindo. Kubalulekile ukuhlala ngizolile hhayi ukuhambisa, ukuze uthole isithombe esinembile. Uma kudingekile, uchwepheshe kungayilungisa ikhanda lesiguli sekhiba ekhethekile ngesikhathi ukuskena.

Lapho sinqatshiwe ukwenza CT scan?

Ngokungafani-magnetic resonance imaging, CT has eziningi ukulinganiselwa. Ayikho inqubo yenziwa iziguli kokuba isisindo 150 kg. Modern imishini imaging ayakhelwe ukuqhuba ucwaningo kulezi ziguli. Indlela ehlukile kulokhu-MRI.

Uma isiguli uhlushwa claustrophobia, scan ikhanda esiyolandelwa kuphela ngaphansi izinzwa jikelele. Nge umlando sina nokugula ngengqondo inqubo is hhayi kwenziwe.

Contraindicated ezibekiwe imaging kwabesifazane abakhulelwe. Phakathi lactation kungenzeka CT kwenziwe, kodwa ezinsukwini olandelayo kufanele ithawula ibele nobisi express.

Kungenzeka yini ukuba sifeze inqubo izingane?

Ethwele imaging seziguli ezisencane kungenzeka, kodwa kuphela amacala isidingo esikhethekile. Ukuze umzimba wengane X ray emisebeni kuyingozi. Ngakho-ke, scan CT ngokuvamile sithathelwe indawo-magnetic resonance imaging, lapho wasebenzisa emisebeni kagesi. Ngonyaka wokuqala wokuphila womntwana, lapho fontanelle elisavulekele, ukuphenya isimo ingqondo ivumela le ndlela ukuxilongwa njengoba neurosonography.

Tomogram ikhanda angabelwa ukuba izingane kulezi zimo ezilandelayo:

• Imiphumela yaloku kuhlola okungenhla yokuzalwa bekhubazekile;
• waqinisa intracranial;
• iphimbo;
• kwezinso semithambo, izinhlumba;
• izinsolo of Oncology;
• yezifo zengqondo;
• ukulimala, nemivimbo, waphuka Yekhanda.

Indlela ukulungiselela ingane yakho?

Yenza ikhanda tomogram ingane ngaphandle ukubulawa kwezinzwa noma ukupholisa akwenzeki ngaso sonke isikhathi ngenxa yobudala izici. Izingane nzima ukubamba namanje phakathi imaging scan. Ngaphezu kwalokho, ingane ungase wesabe imisindo, okuyinto ishicilela umshini zokusebenza. Yingakho inqubo wenziwa ngaphansi izinzwa jikelele. Isimo ingane uzolandela obulala izinzwa kanye nodokotela.

Anesthesia ukwenza kuphela esiswini esingenalutho, futhi ngenxa yalokho, esidlweni sokugcina umntwana kumele kube kungakapheli amahora angu-4 ngaphambi inqubo. Izingane zingadla amahora 2-3. Kwezinye izimo, ochwepheshe batusa ukwenza kwangaphambilini electrocardiogram ingane. Uma kudingeka izinhlaka zokuphatha Ngokuphambene amaphakathi, ayacelwa ukuhlola ukuzwela womntwana emuthini.

Ukulungiselela abadala

Le ndlela zokuxilonga akudingi ukuqeqeshwa okukhethekile. Ngokushesha ngaphambi inqubo isiguli kumele suka sufaka ubucwebe. Kufanele waxwayisa mayelana nokuba khona lobuchwepheshe izimila metallic. Akubalulekile ukuba kudlule inqubo on usuthi.

Uma isiguli kuboniswa ephethe tomography ubuchopho usebenzisa ejenti Ngokuphambene, kumele isuswe ukudla 4-5 amahora ngaphambi ukuskena. Uma kungenjalo, kungenzeka isicanucanu, ukuhlanza, isiyezi. Uma kudingekile, isiguli kungathatha sine.

Ukusetshenziswa Ngokuphambene

Uma kudingekile, imaging kungaba kwenziwe usebenzisa ethize Ngokuphambene ejenti. Lokhu kukuvumela ukuba ngeso lengqondo izindawo eziyinkimbinkimbi kakhulu kukhona ezingafinyeleleki ezivamile ze-X ray. Ukuze sifanekise inqubo nendlela ukwenza tomogram ikhanda umehluko? Okokuqala, le ndlela ukuxilongwa kuyadingeka ukuze zeziguli okudingeka hlola isimo izitsha. Colorant ikuvumela ukuthola Kugcwele entsha ischemia nomdlavuza izimila.

Phakathi olulodwa ngemva Ngokuphambene izinqubo ejenti uzobe excreted. Phakathi nale nkathi, kubalulekile siphuza neziphuzo kakhudlwana. Ukuze ugweme imiphumela engemihle, ke Kunconywa ukuba ibhekane uphethwe laboratory kanye siqambe iguliswa umehluko.

Izimo

Sebenzisa i-ejenti umehluko akuvumelekile iziguli kabani yobudala ingaphansi kweminyaka engu-14 ubudala kanye nabesifazane abakhulelwe. Izimo uyalandisa nokwehluleka ukusebenza kwezinso, nokungezwani komzimba nezinto yokubakhona iodine, abanale nkinga, ene-leukemia.

Kwaze kwaba yilapho sebeshiye kungase kubulawe bonke scan Izimo CT ikhanda ozoba. Kufanele kuqondwe ukuthi indlela ubhekwa kakhulu ulwazi, ngakho-ke senqabe uphethwe ngaphandle kwesizathu esizwakalayo, odokotela musa batusa kakhulu. Inqubo kusiza kusaqalwa ukuhlonza isifo futhi baqala ukwelashwa esifike ngesikhathi.

Tomogram ikhanda: incazelo Imiphumela

Ukuqhaqha yalokho, ochwepheshe kungathatha isikhathi esithile. Ngokuvamile izithombe banikwa esigulini imizuzu 30-60 emva kwaleso sifo, kodwa kwezinye izimo kudingeke ulinde isikhathi eside. Ngakolunye uhlangothi isiguli ithola izithombe omnyama nomhlophe, CD ne ukuqopha kanye nencazelo zithwetshulwa idatha.

Iyaphendulwa kufanele kudokotela uyofuna icebiso, ngubani yakhipha isiqondiso sokuba ukudlula tomography ekhanda. Ngokuzayo singadinga uthintane nezinye Ochwepheshe.

Izindleko kanye nokubuyekeza

Ngokusho ochwepheshe, inhloko tomography umonakalo eziphathekayo umzimba womuntu akusebenzi, uma ucwaningo kwenziwa imishini emisha. Umthamo isilinganiso oyedwa kweseshini 6 m3v. Ukuphenya isimo kogebhezi ubuchopho ngemisebe ingeqi 2 m3v.

Iziguli belulekwa ukuba makudle multislice imaging, okuyinto ngesikhathi esifushane (imizuzwana embalwa) usebenze inqwaba tincetu futhi athwale aphansi umthwalo ngemisebe. Intengo Ukwelashwa ngokuvamile incike imishini futhi uhla 3 000-5 000. Uma kunesidingo, sebenzisa indlela lokhu okuhluke ngayo ejenti intengo inqubo kuzokhulisa ukuba 7 000-12 000.

Iziguli eziningi uqale isipiliyoni, ukufunda ukuthi inikwe scan CT ekhanda. Izibuyekezo of the inqubo ukuqinisekisa ukukhathazeka kwabo, kanye neziguli sebeqala senqabe ibhekane ukuhlolwa. Eqinisweni, kuphela kuchubekisela isimo. Imiphumela yaloku kuhlola okungenhla Esifike Ngesikhathi ivumela isikhathi ukuthola thuthuva kancane ku isimiso sezinzwa futhi emizameni yokwelapha. Ungakhathazeki mayelana ngemisebe ngoba umthamo kuyoba esincane futhi ngeke ukulimaza impilo.
