Chii chakasiyana ane MRI CT? Mune zvimwe zviitiko, MRI CT nani?

mushonga pamwero pari yakakwirira zvikuru. Pane zvidzidzo zvizhinji anotigonesa kuti zvakarurama rokuongorora. Ari zvombo kuvarapi - noungwaru zvigadzirwa. Uchibatsirwa wavo zvinokwanisika kutarisa mukati mumuviri uye zvinoratidza zvokurwara kukura kana mudzimu zvomukati.

itsva idzi nzira chirwere zvinosanganisira rinobva resonance uye computed tomography. Zvidzidzo izvi anowanzoshandiswa kusimbisa chirwere. Vakawanda nzira idzi pasina chiremba wacho zvivabatsire. Muchiitiko chino, zvakakosha kuziva musiyano ane MRI CT.

musimboti oparesheni

Pasinei chokwadi kuti somugumisiro zvidzidzo vose vakawana-dimensional matatu mufananidzo zvomukati, pane musiyano unokosha pakati pavo:

• Maererano mwero nehanya.
• By nheyo chiito.

CT scanner anoshanda achishandisa X-ray. Ndicho installation yose, iyo rotates kumativi muviri murwere, anotora mifananidzo. All zvichiguma mifananidzo vari akatizve pamwechete, uye kurapwa wavo mubasa kombiyuta.

Kusiyana MRI CT rinonyanya anoshanda ari kuti pano hapana maekisirei, uye basa murume ine simba rinonzi magnetic minda. Achifuridzirwa rehydrogen maatomu aripo mumuviri womurwere, zvichienderana akaererana remagineti negwara.

The mudziyo anotumira RF kupomba, riri perpendicular kune huru remagineti. Zvinyama mumuviri womunhu achipinda resonance vibrations uye izvi masero scanner anogona kuziva, decrypt navo uye kuvaka layered mifananidzo.

Zvairatidza kuti MRI uye CT kurapa

Pane zvirwere nokuti izvo hapana musiyano chinokosha, chii tsvakurudza uchava zvakaitika. Somunhu, uye wechipiri chikwata achakwanisa kupa mugumisiro yakarurama.

Zvisinei, pane pathologies umo zvakakodzera kufunga kuti zviri nani - MRI kana CT?

Mris kazhinji ushandiswe kana pane kudikanwa hwakadzama kuongorora nyoro zvinyama mumuviri, tsinga, tsandanyama uye mapfundo. On mifananidzo izvi zvose pathologies vari zvakanaka mavara.

Asi skeletal hurongwa nokuda duku zviri rehydrogen protons havaratidzi vanoteerera rinobva nemwaranzi, uye mugumisiro angasava yakarurama zvachose. Muzviitiko izvi zviri nani kuitisa CT scan.

CT anokwanisawo kupa mufananidzo wechokwadi kudzidza pamhango nhengo akadai mudumbu, ura nemapapu.

Kana isu kutaura pamusoro zvirwere, kuti MRI kunoratidzwa nokuda:

• Nevanga.
• Diagnosing zvirwere pelvic zvomukati.
• Kudzidza trachea, yegurokuro nemidziyo ropa.

CT scan nani kuitisa ongororo:

• Respiratoria hurongwa.
• Itsvo.
• Nhengo dzose dziri abdominal mhango.
• The skeletal hurongwa.
• Kana diagnosing chaiwo nzvimbo kukuvara.

Saka, zviri pachena kuti MRI uye CT musiyano nhema dzakasiyana pfungwa chikumbiro iri.

Contraindications nokuti nzira

Pasinei kugona kwaro, vose mano vane contraindications. Kakawanda varwere kuramba computed tomography nokutya X-ray. Pakupindura mubvunzo kuti zviri nani, MRI kana CT scan, vanongoda kusarudza chidzidzo chokutanga.

Kunyatsoongorora zvinogona kuonekwa kuti zvose zvipenyu ane contraindications ayo.

Chii chakasiyana ane MRI CT, zviri zviratidzo zvavo. Computed tomography hakuratidzwi:

1. Pregnant vakadzi (nokuti ngozi nemwaranzi nezvemidzimu azvarwa).
2. vana vaduku.
3. For kakawanda.
4. Kana kuvapo gypsum mumunda kutsvakurudza.
5. In renal insufficiency.
6. Paanenge achiyamwa.

Magnetic resonance kuri anewo contraindications yaro:

1. Claustrophobia, kana munhu kutya Akanyatsovharwa dzezvimwe.
2. Kuvapo iri muviri pacemaker.
3. The trimester rokutanga pamuviri.
4. Large muviri uremu (110 kg).
5. Kuvapo simbi anodyara Somuenzaniso, muna majoini.

Zvose izvi mhedziso contraindications, asi asati nzira, unofanira bvunza chiremba wako, pamwe panyaya yako zvakare chaizvo kutevedzera.

Zvakanakira rinobva resonance kuri

Kuti tinzwisise zviri nani - MRI kana CT scan, unofanira kufunga zvakanakira mumwe mhando kudzidza.

Magnetic resonance kuri ane zvizhinji zvakanaka zvinhu:

• ruzivo zvose zviri zvikuru yakarurama.
• Ndiyo nzira inonyanya idzidzise ekudzidza varwere maronda ari nechepakati tsinga.
• Zvakarurama rokuongorora vertebral heniya.
• Zviri yakachengeteka kuongororwa kuti vakadzi vane pamuviri uye vana.
• Inogona kushandiswa kakawanda zvaunofanira.
• Absolutely nyarara.
• Vakawana-dimensional matatu mifananidzo.
• Zvinokwanisika kuchengetera mashoko ari kombiyuta Gwaro.
• Mukana kutanga mashoko zvakaipa anenge razero.
• No X-ray chokupfeka.

Kupiwa zvechadenga chiridzwa wayo nheyo oparesheni, panguva yechidzidzo angava ruzha anogogodza, izvo usingafaniri kutya, unogona kushandisa pamahedhifoni.

Advantages computed Tomography

In chitarisiko, zvose tomograph akafanana chaizvo. Mugumisiro basa ravo riri kungogumira kugadzirwa matete zvikamu munzvimbo akadzidza mumufananidzo. Pasina kudzidza hwakadzama zvakaoma chaizvo kuti mutsauko pakati MR kuti CT.

Zvakanakira CT zvinosanganisira zvinotevera:

1. Zvachinja kudzinga-dimensional matatu mufananidzo kudzidza nzvimbo.
2. mifananidzo zvakajeka skeletal hurongwa.
3. Hakuna marwadzo panguva nzira.
4. The yose kudzidza anotora maminitsi mashoma.
5. The nyore uye rakavimbika mashoko.
6. MRI anotipa yakaderera dose nemwaranzi pane X-ray machine.
7. Inogona firimu pamberi simbi kana nemagetsi mano mumuviri.
8. Rinopa wechokwadi uye yakarurama mashoko munyika kubuda ropa, bundu vasabatwa.
9. Lower mutengo zvichienzaniswa MRI.

Sezvaunogona kuona, imwe CT scanner asina kutomboderera avo zvakanakira rinobva resonance, saka kuti zviri nani - MRI kana CT, dzinofanira kutariswa nechimwe.

Zvakaipira chimwe nechimwe mhando kutsvakurudza

Panguva ino vanenge mhando dzose kuongorora vane zvinhu zvakanaka uye nekuipira. Scanners panyaya iyi haisi anosara.

Zvazvakashatira MRI Diagnostics ndivo zvinotevera:

• Zvakaoma kudzidza negomba zvomukati dzakadai Urinary uye nenduru dundira, mapapu.
• Metal nhengo mumuviri womunhu uchava chipingamupinyi kuti muitiro.
• nguva yakawanda inodiwa kuti kudzidza.
• Kuti vawane wechokwadi uye yakarurama kunoguma kwenguva refu murwere anofanira kuva munhu akadarika chinzvimbo.

Computed Tomography nekuipira vari:

• Kudzidza haripi mashoko pamusoro dzichipfekeka mamiriro zvomukati uye nyama, asi chete maumbirwo yavo.
• Zvinokonzerwa X-ray.
• Contraindicated kuvakadzi pamuviri uye vana.
• nzira iyi haigoni kuitwa kakawanda.

Kana uri varumbidzwa vaviri nzira tsvakurudzo, muchiitiko ichi, hazvina mhosva zvikuru zvakasiyana kubva MRI CT.

zvakwo nzira

Mushure kushanyira chiremba, iwe uchava yakarongwa rokuongorora, iyo, vari mafungiro chiremba, kupa wechokwadi uye yakarurama mugumisiro.

Kana ukasarudza kwete kumirira kunenge, zvinokosha kuziva umo nyaya iyo mudziyo kusarudza.

Kana usingazivi chii chaiwo - MRI kana CT scan, yeuka kuti MRI achapa zvakawanda yakarurama uye anodzidzisa zvabuda pasi zvinotevera pathologies:

1. rouropi, sitiroko uye nemultiple sclerosis.
2. zvirwere zvose zviri musana.
3. Intracranial zvokurwara of tsinga uye uropi.
4. Kukuvadzwa tsandanyama nemarunda.
5. Soft tishu bundu.

Kana iwe uri zvakakomba kutyorwa anokosha, zvakakodzera mberi bvunza chiremba wako.

Uwane ruzivo CT kuda, kana iripo,

• Vanofungidzirwa intracranial ropa, kunotevera.
• Damage uye mapfupa chirwere.
• Zvokurwara of kufema hurongwa.
• Atherosclerotic vascular maronda.
• Maronda ari rune marangwanda, thyroid.
• Otitis uye sinusitis.

Preoperative kudzidza ichapa ane mufananidzo yakarurama mune kuuya kuvhiyiwa.

Kana ukatenda zvakasimba vanofungidzirwa nechirwere, uye iwe unogona kusarudza nzira tsvakurudzo yako.

The huru Kusiyana nzira

Pasinei kufanana zhinji kudaro, musiyano pakati CT uye MRI achiripo. Kana mashoma pfungwa, zvino tinogona kutaura zvinotevera:

1. Chinonyanya kukosha musiyano pakati nzira mbiri idzi kutsvakurudza nhema zvavo musimboti kushanda. MRI anoshandisa remagineti, uye CT - x-ray.
2. Nzira zvose zvinogona kushandiswa rokuongorora akawandisa pathologies.
3. Pamwe chete mugumisiro kungava zvomuzvarirwo MRI kusarudza, sezvo kudzidza uyu akachengeteka zvikuru, asi tinorasikirwa zvakawanda.
4. Mumwe nzira ine contraindications ayo, saka vanofanira waongororwa usati chokupedzisira sarudzo.

Yeuka, utano hwako uri pamaoko enyu, uye dzimwe nguva hazvina basa kuti chirwere nzira mhando kushandiswa, chinonyanya kukosha - kuti imwe nguva yakanaka yakarurama uye wechokwadi uye kutanga kurapwa.
