MSCT - kuyini? MSCT esiswini. MSCT ingqondo

Enye yezindlela zesimanje iningi uphenyo kwezicubu womuntu kanye nezinhlaka - okungukuthi multislice ngekhompyutha tomography, noma MSCT. Kuyini futhi kanjani ucwaningo?

MDCT ingenye uhlobo CT (ngekhompyutha tomography). Umgomo we inhlolovo benayo: ngosizo-X-ray ukumuncwa sisebenzisa izicubu imishayo umehluko ezahlukene ukuminyana izingqimba isithwebuli uhlola umzimba wesiguli. Kodwa lapho MSCT isetshenziswa ilungiselelo iyimidwebo imitshina kanye lwento kuzishumeki asetshenziswa CT.

D inzwa afanayo multislice isithwebuli esishukumisela endaweni Kuvunguza ezungeza wonke umzimba wesiguli, kwenza kube nokwenzeka ukuthola izindengezi eziningana evumela ngesivinini image bamba izindawo ezinkulu. Lesi siqeshana okuholela icutshungulwe futhi uboniswa evamile noma Ubukhulu ezintathu. isivinini inhlolovo High kusiza ukuxilongwa kweziguli ugula ubangwa nezibi futhi inikeza ithuba bheka umahluko phakathi izitsha.

MSCT isetshenziswa ngokuphumelelayo ekuhloleni umdlavuza, izifo zenhliziyo kanye ezithathelwanayo, kanye umonakalo uhlelo zemisipha, futhi ukopha ezicutshini futhi izitho ngenxa yokulimala.

Yiziphi izinkomba for MSCT?

Imiphumela yaloku kuhlola okungenhla yamanje izifo eziningi kakhulu ukukholelwa ngaphandle MSCT. Yini lokhu kuhlola kwembula, futhi ngaphansi kwaziphi izinkomba linqume multislice ngekhompyutha tomography?

Uma kukhona izimila, aqukethe metal, ezokwenza kuphela ukusiza e sitholakele tomography multispiral, nama-MRI nakuma-CT scan kuthiwa contraindicated emzimbeni wesiguli. In izifo ezidinga ukwelashwa okuphuthumayo, noma kuhambisana sebuhlungwini obunzima, lapho umuntu akakwazi amanga ngaphandle ezihamba isikhathi eside emzimbeni, MSCT kungaba kuphela indlela efanele ucwaningo. Multislice ngekhompyutha tomography kubuye esisemqoka amacala enjalo yezokwelapha:

1. Ivumela hhayi kuphela ukuxilonga umdlavuza kumiswa isibindi, ubende, amanyikwe, isinye, izinso kanye izimila retroperitoneal endaweni vneorgannyh nesisu, kodwa futhi inquma izinga lomonakalo futhi uhlobo isimila: kungavamile ukuba ingozi noma abulalayo.

2. Inikeza ukusazi ngokunembile isifo esikuphethe ukuze waphuka kohlelo lwamathambo, izinguquko esiwohlozayo yomgogodla, zithinteka ithambo metastases lembula herniation kabuhlungu emgogodleni lumbar.

3. embolism Lapho yamaphaphu ichaza abahluphayo kwegazi igazi nokuthi leso senzo senziwe ukulimala kwemithambo emikhulu.

4. ukulimala Zonke ezinkulu zingathethelelwa kahle esikalini kuphela esebenzisa multislice Enani.

5. Ivumela ukukhomba ngisho emaphaketheni amancane angawodwa sofuba.

Edinga ngcono Ngokuphambene?

Kungase kudingeke ukucwaninga amagama tomograph multispiral kwenza omkhulu ukubona hhayi kuphela amathambo izitho womoya, kodwa futhi izicubu zomzimba ezithambile. Lokhu kwenza kube nokwenzeka ukuxilonga izifo ezingathi sína kwababhemayo kusaqalwa, isibonelo, ukukhomba umdlavuza owayemude encane, uma kukhona namanje kungenzeka ukwelashwa kuhlinzwa. Ukugqama isithuthukisi isetshenziselwa kwamangqamuzana kangcono kwezitho zomzimba ngaphandle izakhiwo ezivamile neziqu sokugembula. Kukhona izindlela ezimbili MSCT nge umehluko: emthanjeni futhi bolus.

Ngo indlela yokuqala konemimoya Ngokuphambene sivela ngaphandle ukulungisa isikhathi nesivinini umthambo roentgenographer is wabe eseqhuba ucwaningo. Le ndlela lalisetshenziswa kancane-lokuqala isizukulwane scanner.

Lapho ekhethekile okungafani ejenti bolus nge isipetu injector yethulwa esikhathini set nesivinini. Buhle le ndlela - ke delineates-contrast isigaba, okwenza ucwaningo iyashelela, futhi imiphumela - eziqinile.

Lapho kuxoxwa ngokuziphatha kwezingane multislice ngekhompyutha tomography zobuchopho?

Ngo inqubo yokwelapha yesimanje ukuxilonga izifo zobuchopho ehola isikhundla ithatha cwaningo MSCT. Lolu cwaningo sitholakale lapho izimpawu ngalo Kwenziwa?

MDCT isetshenziselwa uphethwe ngo pathologies ezifana:

• imfundo umdlavuza ubuchopho, kanye anomalies sokugcwaliseka kwaso;
• unhlangothi;
• umfutho ophakeme intracranial, futhi iphimbo;
• ifomu ezingamahlalakhona izifo zenhliziyo nemithambo yegazi;
• ukulimala noma ukuvuvukala kobuchopho;
• izigaba oyingozi futhi ezingalapheki kwezifo of endlebeni noma sinuses paranasal.

Nge ikhanda njalo futhi obunzima, inkumbulo ukungakhuli, isiyezi kuyadingeka ukuba kulungiswe ukuze udokotela wezinzwa ngoba ekhuluma isidingo ubuchopho MSCT ngoba exclusion izinguquko ezisongela ukuphila sokugembula emzimbeni. Lokhu kubalulekile ikakhulukazi uma kuhlinzwa iziguli ezifuna baye bahlupheka esikhathini esidlule, okulimala ebuchosheni, unhlangothi, lezivakashi kuhlasela ischemic , noma zonke izimpawu isimo predinsultnogo ngesikhathi sokwelashwa kudokotela.

Izimpawu I-multislice CT esiswini

Lapho efeza MDCT besisu udokotela ucubungula kwezicubu, kwezitho izinhlelo kulo mkhakha: isibindi, ipheshana biliary, nenyongo sesinye, ubende, izinso, ngomgudu womchamo, amanyikwe kanye nezinye izitho. radiologist Isazi uhlola isakhiwo, isayizi nendzawo kwezitho; ukuba khona neoplasms sokugembula; khona concrements emizimbeni yalesi zone; ukusebenza Amapayipi Bile; lymph isimo engeyokuqala.

Izimpawu I-MDCT isikhala esiswini retroperitoneal:

• oncological futhi neoplastic lesion kumiswa (metastases);
• izinhlumba, adenomas, futhi abscesses;
• balimale kanzima umonakalo okusolwa kwezitho imithambo yegazi;
• urolithiasis;
• isifo sokusha;
• yisiphi isifo we komgodi ongaphakathi kwamathumbu;
• izinqubo ukuvuvukala;
• zokugula le-aorta besisu futhi emagatsheni awo, nenyama
• isitho anomalies.

Lapho iqondiswa MSCT kwesifuba?

Ukuze ukuhlola isimo kwezitho nezicubu kuphela endaweni kwesifuba isetshenziselwa ulwazi okuqukethwe eliphezulu kakhulu indlela ucwaningo - MSCT. Lokho inhlolovo ilinganisela, futhi ngaphansi kwaziphi izifo ke ezinqunyiwe?

Le nqubo ivumela ukuhlaziywa kanye nokuhlola lezitho nezicubu esithambile thorax (emaphashini, inhliziyo, imithambo yegazi, emphinjeni, kuqhoqhoqho, njll), izindlala zamanzi, ithambo izakhiwo.

Izinkomba MSCT esifubeni:

• isimila kwetinhlavu kanye Ukudlulela;
• okungahambi ngendlela kanjalo kombungu ezisekujuleni kwenhliziyo futhi umgudu wokuphefumula;
• ekubhebhetselisa isifo samaphaphu;
• ukuvuvukala okubangelwa kokunqotshwa esifubeni;
• ukulimala kabi.

Inqubo MSCT: izincomo, izindleko, kanye contraindications

Ukuze isifundo MSCT kudingeka bagqoke izingubo okuxekethile. Zonke lezinto angaphandle kanye imihlobiso kufanele zisuswe kuze kuphele isikhathi nezinqubo, kuhlanganise izinsizakuzwa noma amazinyo. Udinga ukuba bangayeki ukudla amahora ambalwa ngaphambi isivivinyo, ikakhulukazi uma usebenzisa indlela staining.

Isifundo ngokuphelele kobuhlungu, njengoba umthamo ubuncane emisebeni wathola. Inqubo kuthatha (kuncike eyinkimbinkimbi) amaminithi angu-5 kuya ku-30 ka, ke kudinga baxhashazwe nesineke.

Ukusetshenziswa Ngokuphambene kulolu cwaningo, uhlobo Ngokuphambene ejenti kanye nobungako yayo - izici ezithinta ukubaluleka MSCT. Intengo futhi kuncike indawo kanye nobungako endaweni inhlolovo, izinkinga ekuxilongweni kanye namasevisi ezengeziwe. Cacisa ukubaluleka kwanoma yimuphi MSCT kungenzeka ngokuya ikhasi emtholampilo ekhethiwe noma ngokuxhunywa ngocingo. Ngokwesilinganiso, inqubo enjalo, amanani isukela 1.5 kuya kwezingu-11.5. Hlikihla.

Izimo nezingozi MSCT

• lactating abesifazane izinsuku emva nokuphathwa Ngokuphambene kungavunyelwe yokudla;
• izifundo iziguli abakhulelwe wenziwa ngenxa yezizathu zempilo;
• ucwaningo kwezingane uma ngiphoqelekile ngempela futhi kungenzeka kabusha ukwelashwa;
• kakhulu kuyaqabukela iguliswa amanxusa Ngokuphambene eziqukethe iodine.

isiphetho

MDCT kuyinto kobuhlungu futhi ulwazi indlela zokuxilonga kunezinzuzo eziningana:

• Ziveza ngokuphelele amathambo izicubu zomzimba ezithambile, kwakheka imithambo yegazi;
• ucwaningo high speed kubalulekile ikakhulukazi izimo ezinzima eziphuthumayo;
• Imiphumela engcono, akanandaba ezinyakazayo isiguli kanye nezindleko eziphansi ngaphandle MRI;
• ukuqhuba izinqubo kancane koda wenza sikwazi ukwenza ngaphandle kokungenela kuhlinzwa ngezinhloso zokuxilonga;
• ukuchayeka sakugcina futhi akukho emisebeni asalile ngemva kwesifundo.
