Kodi CT jambulani? CT msana. yopangidwa tomography

Masiku ano, pafupifupi aliyense anamva kompyuta tomography, chifukwa kutchuka kwake. Koma kwa iwo amene anawatumiza, ndikofunika kudziwa mwatsatanetsatane zimene CT ndi mfundo za ntchito zake.

mwachidule

Yopangidwa tomography (CT) aone - ndi stratified phunziro la makono a thupi. Bukuli lili ndi chingwe kompyuta ndi processing kusiyana attenuation nsalu X-poizoni osiyana mu kachulukidwe awo. Kugwiritsa yopangidwa Tomography kusanthula thupi aona kuchokera kumathandiza kupeza ngodya zosiyanasiyana, n'zotheka kupeza chifaniziro zolosera onse ndi maonekedwe atatu azithunzi omwe tikunena.

Kuchita CT amagwiritsa ntchito yapadera X-ray CT sikana. Pamafunikanso tebulo makina, kulowa wodwala ku kutsegula kwa unit chindodo, mmene masensa ndi cheza ndi X-ray chubu.

X-ray kudutsa kuphunzira thupi cheza anthu amakhala ofooka mmene umadutsa minofu. Limazungulira pa makona a madigiri 360 mozungulira wodwala, X-ray emitter mapanga sikani gawo la thupi lake pa kumathandiza kupeza ngodya zosiyanasiyana. Panthawi imeneyi masensa oyenerera mu mbali ina ya mtima zinakhalira mu kutembenuka kwa zikhumbo cheza mphamvu zamagetsi. Kenako kudutsa processing kompyuta chifukwa cha zomwe Tingaone pa polojekiti ndi. The analandira maphunziro chifaniziro ri radiologist, ndiye analemba kuti sing'anga kujambula ndi zipsera iwo pa tepi. The lonse kafukufuku ndondomeko sakondwera kuposa mphindi 10, koma malingana sikana ndi yeniyeni matenda zone chofunika ndi kwa theka la ola.

Ayamikira isanayambe kapena itatha mayeso

Odwala amene anali atalandira CT jambulani, ndikufuna kudziwa: Kodi CT jambulani, amene ayamikira chiyenera kuchitika isanafike ndondomeko, pa kenako. Pakuti mitundu yonse ya aone izo akulimbikitsidwa maola 2 asanayambe kuphunzira kukana chakudya ndi kumwa. Kwa matenda a ziwalo zina, ndipo zina mwa zochita dokotala amafunika mtsempha Mosiyana wothandizila kusintha zotsatira za phunzirolo. Izi kuchenjeza yense wopirira kupezeka dokotala kapena madokotala CT ofesi.

Nkofunika kudziwa kuti ngati wodwalayo ali ndi magetsi, makina ndi maginito amadzala (ziwalo, zitsulo mbale, pacemakers), tsiku lina isanafike CT anali maphunziro ntchito barium kuyimitsidwa, komanso pa mimba m'pofunika kudziŵitsa dokotala.

Kuphunzira thupi akhale opanda zovala ndi zodzikongoletsera. Pa kuona zodalirika zotsatira mukufuna kugona akadali, mungafunike kupuma likhale masekondi angapo. Yopangidwa tomography - sabweretsa chisoni mwamtheradi mayeso.

Pambuyo RT ndi m'nsinga kutumikiridwa mankhwala kuti achire oyambirira mthupi ndi zofunika kwa maola awiri kuti mpaka malita 2 madzi.

ndi zizindikiro ntchito CT chiyani?

Yopangidwa tomography ntchito zonse, mwadzidzidzi, mankhwala ndi matenda njira, monga kuwunika puncture lapansi.

Monga kuyezetsa magazi mayeso m'pofunika kuti CT ndi mutu pafupipafupi, makamaka limodzi ndi kusanza, imfa nthawi ya kutsitsimuka kapena khunyu, kuvulala m'mutu, komanso kuti achotse oncological khalidwe la maphunziro.

Mu kafukufuku amene anachitika mwamsanga anavulala kwambiri, amaganiziridwa kuwononga moyo pachiswe ziwalo, mitsempha ya magazi, matenda a ubongo haemorrhage.

Pamene kuchita CT wa pamimba?

M'mimba yopangidwa tomography danga ntchito matenda molondola matenda ndulu, ndulu, chiwindi, kapamba, m'mimba, ndi lstogo intestine.

CT pamimba ambiri ikuchitika ndi m'nsinga kutumikiridwa Mosiyana wothandizira, kuyambira minofu zofewa ziwalo ndi ovuta oterewa. Tisiyanitse ndi katundu womangidwa kudziunjikira mu zimakhala zosiyana, ziwalo limachititsa kusiyanitsa Chrixitu, lomwe limakonda matenda zolondola.

zizindikiro zimene madokotala analimbikitsa amathera CT m'mimba: ululu pafupipafupi m'dera m'mimba, mawonekedwe chikasu pathupi ndi sclera, kuchepa magazi, modabwitsa kuwonda, mapangidwe ndi chikhalidwe zovuta kuzimvetsa, wapezeka ndi ultrasound.

Pamene msana ikuchitika kompyuta tomography?

phunziro ili chimagwiritsidwa ntchito kwa matenda a matenda m'mawere khomo lachiberekero ndi lumbar msana. Limawapatsa mpata kuwunika onse dongosolo la mafupa, mitsempha ya magazi ndi minofu zofewa ndi kupeza atatu azithunzi omwe tikunena fano.

CT msana ikuchitika milandu zotsatirazi:

• kuvulala aliyense msana;
• matenda a anomalies kobadwa nako;
• matenda msana zachilengedwe opatsirana;
• nyamakazi, kufooka kwa mafupa;
• kafukufuku mu zimayambitsa kupweteka (kusintha kwa msana, herniated zimbale);
• chotupa metastasis kapena ziwalo pafupi.

Muyenera kudziwa kuti ngakhale patapita zazing'ono koyamba mu choipa msana, komanso kuwawa kulikonse kumbuyo yochokera ku umodzi wa miyendo m'munsi, muyenera kufunsa dokotala nthawi yomweyo. Only dokotala ndikatha kumfunsafunsa wodwala amasankha kufunika yopangidwa tomography.

ndi zizindikiro kwa yopangidwa tomography m'chifuwa chiyani?

CT sikana wakhala bwinobwino ntchito pa matenda a matenda a dongosolo mtima, mafupa ndi nthiti thoracic kuwunika chikhalidwe m'mapapo. A pachifuwa CT jambulani n'zofunika matenda a:

• chifuwa chachikulu;
• udindo mtima (pamaso pa zotupa, cysts, khoma makulidwe);
• patency ziwiya lalikulu zochizira matenda a mtima;
• lymph mfundo ya chifuwa, sipangakhalenso amangoona mothandizidwa ndi kompyuta tomography;
• kuvulala fupa, zimbale herniated, yotupa ndi oncological njira.

Ndi kukhosomola kwakukulu, thukuta, mwadzidzidzi kuwonda, kufooka ambiri, komanso kuoneka kusintha osadziŵika pa chifuwa radiograph n'kofunika nthawi zonse dokotala chigamulo pa CT mu chifuwa. phunziroli likuthandizani kuthetsa zotupa m'mapapo, matenda awo aakulu, TB.

Kodi kufufuza bwino CT kapena Kujambula?

Lero, njira onse matenda bwinobwino yofunsira matenda olondola a matenda ambiri. Kumvetsa zimene mtundu wa kafukufuku bwino, muyenera kudziwa mawu ambiri kodi CT, mmene kumasiyana ku Kujambula. njira onse ali chinthu chimodzi chofanana - kugwiritsa ntchito njira magawo chindodo m'thupi la munthu. Kupanda kutero, ndi osiyana kwambiri ndipo alibe makhalidwe ofanana mfundo.

Ndi Kujambula mungamvetse udindo wa zimakhala awa: chichereŵechereŵe, mitsempha minofu ndi Mitsemphayi, kotero njira imeneyi n'kofunika kwambiri makamaka neurosurgery. Komabe, pafupifupi si nkhani kwa khansa ya dongosolo ndulu, fractures mafupa, nthiti, msana kuvulala, khansa mu mapapo.

Koma ntchito CT ndi abwino kwa matenda pamwambapa. Ntchito CT ndi yofunika kwambiri kupeza kuvulala atsopano Chigaza, m'mimba ndi ziwalo thoracic. CT komanso bwino ntchito matenda opha ziwalo pa siteji oyambirira.

Pa mfundo imeneyi, tinganene kuti CT ndi Kujambula - njira zosiyanasiyana matenda, omwe ndi ofunika kwambiri ndipo n'kofunika kuti madera ena kafukufuku.

N'koopsa kufufuza thanzi pa kompyuta tomography?

CT munthu amalandira mlingo ka X-ray walitsa, kotero chiopsezo ndi mavuto aakulu chifukwa cha si lalikulu kuposa muyezo radiography. Koma kukana kafukufuku ameneyu ndi kuli umboni mankhwala woopsawo thanzi ndi moyo wa wodwalayo chifukwa chosowa matenda yake ndi odalirika.

Kwa amayi oyembekezera ndisanabadwe kompyuta tomography ndi contraindicated. Komabe, mu umphawi wadzaoneni, monga anavulala kwambiri, matenda ikuchitika ndi kusanjika kwa thewera patsogolo pa mimba yake. Kuyamwitsa mwana si munthu contraindication kwa CT.

Kodi bwino kuchita CT aone?

Kulondola chifukwa yopangidwa tomography kumatengera zifukwa ziwiri: radiologist Luso, khalidwe ndi imapanga luso sikana lapansi. Kuti mudziwe ntchito multisrezovye, multislice, multidetector yopangidwa tomography. Anthu opanga zonse mwa zipangizozi ndi aliyense chitsanzo latsopano mukufuna kuwonjezera cheza mlingo yochepa.

dokotala kuchita kafukufuku chofunika kudziwa ndendende zolinga ndi ndondomeko ya mmene aliyense kafukufuku. Choncho, anthu amene sakudziwa kumene kuchita CT, tikhoza amalangiza: yekha malo aakulu matenda okhazikika mu mbiri chofunika cha matenda. Iwo ndi zipangizo zamakono, amene amapereka khalidwe chithunzi ndi kukhudzana osachepera, ndi ndodo ya akatswiri odziwa ndi oyenerera kuthandiza kuti matenda zolondola.

Mtengo wa tomography yopangidwa

Mu kafukufuku, pali chithandizo awiri: kugwiritsa ntchito kusiyana wothandizira, ndipo popanda - zimadalira mtengo wa CT. Yopangidwa Tomography ndalama imaperekanso phunziro, kuchuluka kwa malo ntchito ndi malo m'dera chindodo. ntchito zina zikhoza m'gulu la mtengo: kusamutsa zotsatira kwa litayamba, zithunzi chachibwereza, ndipo ena. Mitengo pa CT akhoza zokhudza chipatala asankhidwa pa foni.

Pomaliza

Choncho, kulonga n'cigwagwa kodi CT ndi udindo wake mu mankhwala. Yopangidwa tomography ndi masiku ndi ntchito zake zosiyanasiyana njira ya X-ray bwino. Ntchito kompyuta tomography, n'zotheka kufufuza mbali ina ya thupi ndi ziwalo, kuwunika awo mawonekedwe, udindo, kukula, ndi kapangidwe ka kuchifotokoza magwiridwe awo. Njira ntchito kusiyana wothandizila zimapangitsa zotsatira zolondola kafukufuku.

Zitsulo zofufuzira zidazo wa zitsanzo atsopano amatha kupeza mafano a zigawo thinnest minofu (1-5 mm), zomwe zimathandiza kuti bwino ntchito CT kwa matenda a matenda oopsa ambiri pa siteji oyambirira ndiponso kuyan'ana punctures ndi biopsies, ndiwofatsa komanso opaleshoni chithandizo. Lero, ntchito ya madotolo ndi zodabwitsa popanda CT jambulani.
