MSCT - chii here? MSCT dumbu. MSCT pfungwa

Chimwe chezvinhu ano nzira kuongorora kuti nyama dzevanhu uye nhengo - kuti multislice computed tomography, kana MSCT. Chii uye sei kuita tsvakurudzo?

MDCT ndomumwe mhando CT (computed Tomography). Pfungwa yacho muongororo vaine mumwe: tichibatsirwa X-ray Absorção de Água utilizing nyama yacho musiyano matanda zvakasiyana arambe achirema akaturikidzana scanner inoongorora muviri murwere. Asi kana MSCT rinoshandiswa maviri-dimensional urongwa michina uye Linear encoders zvinoshandiswa CT.

Ndeiya yakaita Switch kuko multislice scanner anoita ari zononoka kumativi murwere, zvinoita kuti tikwanise kugamuchira zvimedu akawanda unobvumira mukuru-nokukurumidza mufananidzo kubatwa munzvimbo huru. The zvichiguma Chidimbu chinogadzirwa uye akaratidza anowanzoita kana mune miganhu matatu. High nokukurumidza kuongorora hwezvekukurukurirana nechirwere wevarwere anorwara uye zvinopa mukana siyanisa midziyo.

MSCT iri zvinobudirira kushandiswa kudzidza kenza, zvemwoyo uye zvirwere, uyewo chakakomba kuvadza zvetsandanyama nemapfupa hurongwa, uye ropa munyama uye zvomukati nokuda makuvaro.

Ndezvipi zviratidzo nokuda MSCT?

Current chirwere zvirwere zvakawanda hazvifungiki pasina MSCT. Chii Ongororo iyi inoratidza, uye pasi chii zvinoratidza varayire multislice computed tomography?

Kana paine anodyara, ane simbi, kuti zvichabatsira chete nechirwere pamusoro multispiral tomography, uye MRI uye CT Scans vari contraindicated mumuviri womurwere. In zvirwere zvinoda kukurumidzirwa kurapwa, kana ari achiperekedzwa irwadziwe kwazvo, kana munhu haasi kukwanisa nhema pasina unomutsa kwenguva yakareba, MSCT yaizova nzira yakarurama chete kutsvakurudza. Multislice computed tomography kuri kushaika chakadaro zvokurapa nyaya:

1. Inokutendera kwete chete rokuongorora kenza paumbwe chiropa, chirwatata, rwatata, dundira, itsvo uye retroperitoneal mapundu vneorgannyh nzvimbo uye dumbu, asiwo anosarudza ukuru kukuvadza uye mhando bundu: benign kana akaipa.

2. Anopa kuongororwa zvakarurama nokuda mitswe pamusoro skeletal ezvinhu chinopedza kuchinja zviri nomuzongoza, ari kukanganiswa mapfupa metastases anoratidza herniation ari lumbar nomuzongoza.

3. Kana pulmonary embolism rinorondedzera vachivavhiringidza muropa riparadzirwe uye ukuru kukuvara mikuru arteries.

4. Kukuvara All chakakomba chinogona zvakanaka kungoonekwa chete achishandisa multislice scanner.

5. Inokutendera kuziva kunyange zviduku uye yoga muhomwe tibhii.

Kunoda musiyano enhancement?

Research pamusoro multispiral tomograph inoita zvikuru kuona kwete chete mapfupa uye pneumatic zvomukati, asiwo nyoro tishu. Izvi zvinoita kuti tikwanise kuziva zvirwere zvakakomba mukutanga mumatanho Somuenzaniso, kudoma malignancy zviduku saizi, kana pachine mukana kuvhiya kurapwa. Mukupesana enhancement rinoshandiswa kuti nani Kusiyanisa kwevanhu nhengo kunze kwomuzvarirwo hurongwa pathological growths. Kune nzira mbiri MSCT pamwe Kusiyana: intravenous uye bolus.

In nzira yokutanga musiyano svikiro kutaurwa pasina nokugadzirisa nguva uye nokukurumidza mune roentgenographer tsinga iri ipapo tsvakurudzo. Nzira iyi raishandiswa nomumugwagwa kwaitora nguva yokutanga-chizvarwa scanners.

Chaiwo achisiyanisa mumiririri bolus Via sirinji injector kutaurwa kuti nguva uye nokukurumidza. Kunakisa nzira ichi - nayo delineates Pasika musiyano, izvo zvinoita rikurumidze tsvakurudzo, uye migumisiro - zvikuru hwakavimbika.

Apo mufambiro multislice computed tomography uropi?

In mushonga ano rokuongorora zvirwere uropi kutungamirira nzvimbo inoremekedzwa kudzidza MSCT. Kudzidza ari kana zviratidzo izvo voitakura kunze?

MDCT rinoshandiswa kuti chirwere muna pathologies dzakadaro:

• dzidzo kenza uropi, uyewo anomalies wayo kukura;
• Kurohwa;
• yakakwirira intracranial kumanikidzwa, uye hydrocephalus;
• chisingaperi chimiro zvemwoyo chirwere;
• pakukuvara kana kuzvimba uropi;
• chenjera uye chisingaperi zvokukura nezvirwere womukati nzeve kana paranasal sinuses.

With kakawanda uye kwazvo nomusoro, ndangariro vanotaura, dzungu zvakakodzera kutaura kuti wetsinga kuti kugadzirisa kudiwa uropi MSCT kuti achisiya zvinouraya Kumwe kuchinja kunotanga mumuviri. Izvi zvinonyanya kukosha kune varwere vakatambura kare, kukuvara uropi, sitiroko, zvinopfuura ischemic kurwisa , kana vane zvose zviratidzo predinsultnogo mamiriro panguva kurapwa nachiremba.

Zvairatidza kuti multislice CT dumbu

Paaiita MDCT abdominal chiremba Anoongorora munyama, nhengo uye hurongwa mumunda ichi: chiropa, biliary turakiti, nduru dundira, chirwatata, itsvo, Urinary turakiti, rwatata uye dzimwe nhengo. Nyanzvi radiologist anoongorora mamiriro kukura uye chinzvimbo zvomukati; kuvapo pathological neoplasms; Kuvapo concrements mu zvitunha mapazi ichi; functionality of bile ducts; node raiva pedyo nebundu chinzvimbo.

Zvairatidza kuti MDCT ari mudumbu uye retroperitoneal nzvimbo:

• oncological uye neoplastic lesion inotungamirwa (metastases);
• cysts, adenomas, uye abscesses;
• vanotambura zvakakomba uye vanofungidzirwa kukuvara mapazi nemidziyo ropa;
• urolithiasis;
• cirrhosis;
• chero chirwere of abdominal mhango;
• anogumbura pezvakaitwa;
• zvokurwara of abdominal yeropa uye awo;

Kana achiita MSCT pechipfuva?

Kuongorora mamiriro mapazi uye nyama munzvimbo pechipfuva rinoshandiswa nokuda soro mashoko zviri tsvakurudzo nzira - MSCT. Kuti kuongorora inofungidzira, uye pasi chii zvirwere zvinonzi ushandiswe?

Nzira iyi inobvumira kuti kuongorora uye kunyatsoongorora nhengo uye akapfava nyama yacho thorax (nomumapapu, mwoyo, tsinga, yegurokuro, trachea, etc.), node nodes, mapfupa zvivako.

Zvairatidza MSCT bhokisi:

• bundu inotungamirwa uye metastasis;
• anomalies uye malformations zvomwoyo uye kufema hurongwa;
• diffuse bapu chirwere;
• kushoma anokonzerwa pokukundwa pechipfuva;
• zvakakomba makuvaro.

MSCT nzira: vanorumbidza, cost, uye contraindications

Kuitisa chidzidzo MSCT vanofanira kupfeka nzenza zvipfeko. zvinhu zvose vatorwa uye zvemaoresa vanofanira kubviswa nokuda nguva yose nzira, kusanganisira zvinoyamura kunzwa kana dentures. Unofanira kurega kudya kwemaawa anoverengeka pamberi bvunzo, kunyanya kana tichishandisa nzira staining.

Study zvachose nyarara, sezvo shoma dose nemwaranzi akapiwa. The nzira anotora (zvichienderana kunzwisisa) 5 kusvika 30 maminitsi, zvinoda mwoyo murefu kutadza kufamba.

Kushandiswa Mukusiyana vari kudzidza, mhando kusiyana mumiririri wayo uwandu - zvinoita kuti chokuita kukosha MSCT. The mutengo inobvawo pamusoro nzvimbo uye pakasvika muongororo yacho, diagnosing matambudziko uye yokuwedzera mabasa. Kujekesa kukosha chero MSCT ave nokuenda peji yacho yasarudzwa kukiriniki kana kuti norunhare. Paavhareji, kwakadaro muitiro, mitengo siyana 1.5 kusvika 11.5 zviuru. Kwiza nechekuzasi.

• chaizvo kashoma sema kuti musiyano nevasori kuti ane ayodhini.

mhedziso

MDCT ndiye nyarara uye anodzidzisa chirwere nzira ine dzakawanda zvakwakanakira:

• zvakakwana visualizes mapfupa uye akapfava rinenge midziyo ropa;
• Kutsvakurudza kumhanya zvinokosha kunyanya zvikuru zvaipa mamiriro;
• nani unhu zvabuda, haanyanyi inofamba murwere uye ane mari kuvatumwa MRI;
• kuitisa zvishoma invasive maitirwo ezvinhu zvinoita kuita pasina kuvhiya kupindira kuti chirwere zvinangwa;
• usingashandi vachiona uye hapana residual nemwaranzi mushure kudzidza.
