Yintoni CT scan? CT yomqolo. Itomography ngekhompyutha

Namhlanje, phantse bonke akukuva Itomography computer, ngenxa yokuthandwa kwayo. Kodwa ngabo sele uwunikiwe, kubalulekile ukwazi ngokweenkcukacha yintoni na CT kunye umgaqo osebenza ngayo.

Overview

Itomography ngekhompyutha (CT) scan - isifundo mihla wakubo emzimbeni womntu. Oku kusekelwe yokulinganisa computer nokusingathwa umahluko eziphango of amalaphu X-radiation, ezahlukeneyo mninzi zabo. Ukusebenzisa ngekhompyutha Itomography lahlaziya umzimba kubonakala engile ezahlukeneyo, ngoko kusenokwenzeka ukuba ufumane umfanekiso kuzo zonke uqikelelo kunye form-ntathu.

Ukwenza CT isebenzisa ezizodwa X-ray CT scanner. Oku kuquka itafile eshukumayo, bangene isigulane kwi ukuvulwa unit ukuskena, apho abenzi boluvo ezi radiation kunye X-ray ityhubhu.

Kwathi-X-reyi ngenxa ukufundwa kwemitha umzimba womntu iba buthathaka njengoko udlula kwithishyu. Ezijikelezayo kwi-engile 360 degrees isigulana ngeenxa zonke, X-ray emitter eskena inxenye yomzimba wakhe kwi engile ezahlukeneyo. Ngeli xesha abenzi boluvo zilahlwe kwezinye icala isigulane ababandakanyekayo ukuguqulwa ngamaza ombane amandla radiation. Emva koko baye ngokusebenzisa inkqubo yekhompyutha, isiphumo leyo kungabonwa kwi esweni. I wafumana izifundo umfanekiso nokuhlalutya ray, ngoko ubhalela ukurekhodwa eliphakathi kwaye ishicilela ngazo kwi tape. yonke Inkqubo yophando ithatha ngaphezu kwemizuzu eyi-10, kodwa kuxhomekeke vuavanyisi kwaye kufuneka kommandla ngqo ngoxilongo kwaye ukusa sisiqingatha seyure.

Izindululo ngaphambi kunye nasemva kovavanyo

Abaguli wasizuza CT scan, ufuna ukwazi ukuba: Yintoni CT scan, apho izindululo kufuneka ilandelwe phambi inkqubo, ngexesha nasemva kwayo. Kuba zonke iintlobo scan kucetyiswa ukuba iiyure ezi-2 phambi isifundo ukwala ukutya neziselo. Kuba lokufunyaniswa amalungu athile, kwaye kwezinye iimeko izigqibo ugqirha ifuna arhente umahluko efakwa ukuphucula iziphumo zophononongo. Oku kuya tufwile wonke ugqirha nomonde ukuya okanye i-ofisi CT nabasebenzi bezonyango.

Kubalulekile ukwazi ukuba xa isigulane unalo ukuxilongwa zombane, oomatshini kunye nemagnethi (zitho, iipleyiti zesinyithi, pacemakers), imini enye phambi CT baba izifundo usebenzisa barium ukumiswa, ngokunjalo ngexesha lokukhulelwa kuyimfuneko ngayo ukwazisa ugqirha.

Isifundo komzimba kufuneka ibe simahla iimpahla nezacholo. Ngethuba loviwo lwe ukuthembeka kweziphumo kufuneka balele, kusenokufuneka umoya-ukubanjwa imizuzwana embalwa. Itomography ngekhompyutha - uvavanyo elula ngokupheleleyo.

Emva RT nge kweziyobisi butofelwe ilawulwa zokurhoxiswa kwaso kumzimba kuyimfuneko iiyure ezimbini ukuya kuthabatha iilitha ezi-2 zamanzi.

Zintoni ezibonisa ukuba ukusetyenziswa kwe CT?

Itomography ngekhompyutha isetyenziswa njalo, zikaxakeka, iinkqubo zonyango kunye zokuxilonga, ezifana esweni le okuhlatywa.

Njengoko indlela yokuvavanya kuyimfuneko ukwenza CT kunye yintloko ebuhlungu rhoqo, ingakumbi kunye nokugabha, ilahleko ngamaxesha lokuqonda okanye ukuxhuzula, ukonzakala entloko, ngokunjalo ukwahlula ubhalo oncological zemfundo.

Kuphononongo wenziwe ngokungxamisekileyo balimala, eko umonakalo ubomi esisoyikiso amalungu, imithambo yegazi, lokufunyaniswa a Ukopha ebuchotsheni.

Xa ndisenza CT of esiswini?

isithuba Itomography ngenzolo ngekhompyutha zisetyenziselwa ukuxilongwa lwezifo udakada, senyongo, isibindi, injeke, isisu, i lstogo emathunjini.

CT isisu ngokubanzi kwenziwa arhente umahluko butofelwe elawulwa, ekubeni amalungu kwizihlunu ezithambileyo kunzima ukubona. Thelekisa ipropati ngokungalingani yande zomzimba ezahlukeneyo, amalungu yenza kube lula ukwahlula enye kwenye, nto leyo ukholiswa ukuxilongwa.

Iimpawu apho oogqirha bacebisa ukuba bachithe CT esiswini: intlungu rhoqo kwindawo esiswini, yellowing ulusu kunye sclera, ianemia usinga ukwehla kobunzima, ukuyilwa zohlobo ongaqondakaliyo, ukubonwa ultrasound.

Xa umnqonqo yenziwa Itomography computer?

Olu phando esisetyenziswa ngokubanzi uxilongo lwesifo webele, wesibeleko kunye empontshwa umqolo. Lunika ithuba lokuba ukuvavanya zombini ubume amathambo, imithambo yegazi kunye inyama ithambile nokufumana umfanekiso-ntathu.

CT yomqolo lwenziwa kwezi meko zilandelayo:

• naziphi ukulimala spinal;
• unesifo mgceni bekhubazekile;
• izifo umnqonqo imvelo esosulelayo;
• samathambo, kwamathambo;
• uphando ezibangela intlungu (tshintsho yomqolo, herniated disc);
• ithumba Ukudlulela okanye amalungu ezikufutshane.

Kufuneka wazi ukuba nkqu nasemva kokuba umntwana xa uqala kwi wokwenzakala yomqolo, kwakunye nawuphi na iqolo ibonakala kwelinye nemilenze, kufuneka udibane nogqirha wakho ngoko nangoko. Kuphela ngugqirha emva kokuba kugqitywe uviwo lwe isigulane isigqibo imfuneko Itomography ngekhompyutha.

Zintoni ezibonisa ukuba Itomography ebale le esifubeni?

CT isikeni iye isetyenziswe ngempumelelo ukwenzela iziphumo zokuxilonga izifo kwenkqubo sentliziyo, amathambo kunye iimbambo thoracic ukuhlola imeko semiphunga. A scan esifubeni CT kuyimfuneko lokufunyaniswa:

• tuberculosis;
• isimo wentliziyo (phambi yamathumba, cysts, udonga ubukhulu);
• patency kweenqanawa ezinkulu ngenxa unyango isifo sentliziyo;
• zamanzi esifubeni sakho, nto leyo ingabonwa kuphela ngoncedo Itomography computer;
• ukulimala bone, idiski herniated, iinkqubo ukudumba kunye oncological.

Xa ekhohlela elide, ukubila, ngesiquphe ukwehla kobunzima, ubuthathaka jikelele, kwakunye yimbonakalo utshintsho phaku esifubeni radiograph kuyimfuneko ukuba kusoloko udibane nogqirha ukuze ithathe isigqibo malunga CT esifubeni. Olu phando luza kunceda ekupheliseni nangezilonda umphunga, isifo yabo engapheliyo, isifo sephepha.

Yintoni uphando ngcono CT okanye MRI?

Namhlanje, zombini indlela diagnostic elasetyenziswayo uxilongo oluchanekileyo izifo ezininzi ngempumelelo. Ukuze uqonde ukuba uhlobo zophando ngempumelelo, kufuneka ukwazi ngokubanzi yintoni na CT, indlela olwahlukileyo MRI. Zombini ezi nkqubo unayo enye into efanayo - ukusetyenziswa indlela ukuskena sekhombuya komzimba womntu. Kungenjalo, zahluke kakhulu kwaye azinazo iimpawu eziqhelekileyo umgaqo.

Nge MRI uyakwazi ukuqonda ngcono imeko ngezi kwinyama: intlala, luvo, izihlunu kunye nemisipha, ngoko le ndlela kubaluleke ngokukodwa neurosurgery. Noko ke, cishe akukho zinkcukacha umhlaza ekwenzeke kuzo ilitye le senyongo, kwamathambo amathambo, iimbambo, zokonzakala emqolo, zomhlaza emiphungeni.

Kodwa ke ukusetyenziswa CT ilungele izifo ngasentla. Ukusetyenziswa CT buyafuneka ukwenzela ukufumana amanxeba ukakayi entsha, esiswini kunye amalungu thoracic. CT wasebenzisa ngempumelelo ukuxilonga stroke kusekwangoko.

Ngenxa yesi sizathu, sinokugqiba kwelokuba CT kunye MRI - iindlela ezahlukeneyo diagnostic, nganye kuzo ibalulekile yaye kubalulekile ukuba iindawo ezithile zophando.

Kuyingozi uphando lwempilo Itomography computer?

CT umntu afumana igcuntswana leyeza X-reyi zokukhanya, ngoko ke ingozi yokuba nemiphumela emibi mkhulu kuno-ray eqhelekileyo. Kodwa ke ukungafunwa kwalo uphando kubukho ngobungqina bukagqirha enobungozi empilweni kunye nobomi isigulane ngenxa yokungabikho loxilongo oluthembekileyo.

Kuba abasetyhini abakhulelweyo akukho Itomography computer contraindicated. Nangona kunjalo, kwiimeko ezinzima, ezifana balimala, uxilongo lwenziwa ngokubekwa ifaskoti lead esiswini wakhe. Ibele kungajongwa contraindication ku CT.

Apho kungcono ukwenza CT scan?

Lulungiswe japan Itomography ayifum lixhomekeke kwizinto ezimbini: ray lobungcali, umgangatho amandla lobugcisa vuavanyisi. Kuba kuphando olwenziwayo multisrezovye, multislice, multidetector ngekhompyutha Itomography. Bonke abenzi ezi zixhobo kunye nemodeli ngamnye ezintsha sifuna ukwandisa idosi radiation ukuya ubuncinane.

Ugqirha oqhuba uphando olufunekayo ukuze wazi ngqo malunga neenjongo kunye nezo survey nganye.
