MRI of the sinuses: apho ukwenza ezibonisa? Yokuthwebula ye sinuses

iphecana Upper zemiphunga bavame komtshiso abantwana kunye nabantu abadala. Oku kubangelwa indawo isixokelelwano sokuphefumla. Ngapha koko, ukuba zijonge phantse ngqo okusingqongileyo lwangaphandle (izicatshulwa ngeempumlo, kwisisu ngomlomo). Ngenxa ukudumba iintsholongwane ngokufuthi ukungena kulo bronchi kunye nemiphunga. Ngenxa yeengxaki asakhulayo afana iphika, inyumoniya. Kwakhona, ukudumba le sinuses rhoqo aye nendlebe. Obona bunzima eyingozi ngumthombo kwizixekoapho usuleleko kunye iintsholongwane ekungeneni ubuchopho okanye egazini. Ukudumba le sinuses ekuthiwa sinusitis. Le ngezifo ephatha otolaryngologist. Ukuba ucingela ukuba kufuneka ukuba iimviwo sinusitis - X-ray empumlo. Ukuba imifanekiso akakwazi ukunika ingcaciso epheleleyo malunga ukusasazeka inkqubo kwiintetho ezikralayo, kukho uxilongo eneenkcukacha.

Yintoni MRI sinuses?

Yinto eyaziwayo ukuba sinusitis zahlulwe iintlobo eziliqela. Kucingwa kukukrala uqhelekileyo le sinus maxillary. Kunokuba ibe single kwaye kabini kabini. Ngokuqhelekileyo, nangokurhala senzeka kwi ngokungqalileyo (Front), nesinqumka (sphenoiditis) kunye sinuses latticed (ethmoiditis). Kwakhona usuleleko kunokwenzeka xa zonke ezi zakhiwo yokwakheka. ukukrala ahlangeneyo ama-sinuses kuthiwa pansinusitis. Yiqonde utshintsho kwi radiographs abakwazi njalo. Kule meko, oogqirha bacebisa ukuba enze MRI sinuses. Le ndlela yoviwo instrumental kuvumela ukuzibona kakuhle zonke esikule intamo. MRI inkqubo yoxilongo evumela maleko ukuba nomfanekiso amalungu kunye neenkqubo kummandla othile yokwakheka. Ukuza kuthi ga ngoku, le ndlela kucingelwa ukuba yenye yezona ndlela efundisayo ukuchonga ezimbi. Ikhompyutha kunye intlokoma magnetic yokuthwebula ye sinuses sikuvumela ukuba ubone utshintsho ukuba ungakwazi ubone naziphi na ezinye izixhobo ngenxa uxilongo. Ezi iindlela ezisetyenziswa kakhulu kuwo onke amazwe.

Indlela yokusebenza ye magnetic ekuvakaleni kwelizwi umfanekiso

MRI le sinuses lwenziwa usebenzisa isixhobo okhethekileyo - magnetic ekuvakaleni kwelizwi tomograph. Kuye isigqibo phezulu, njengoko kuyimfuneko ukuze ngokupheleleyo kumguli. Le ndaba kwindawo lisalele esofeni, ibe ifowni kwigumbi semilo zezindlu. Ngaphakathi kungenisa endle ngemagnethi. Njengoko yaziwa, kwiseli nganye emzimbeni womntu unalo ityala. Ngoko ke, xa engena zone yethishyu lamaza kagesi uqalise sicaphuka. Iiseli ziqala like "nendlebe 'ngenxa amandla umahluko. Ngenxa yoko, ekuvakaleni kwelizwi kwenzeka. Ezi nguqu yathinjwa boluvo ezikhethekileyo axhonywe esweni. Ngesi abasabela ngayo iiseli zomzimba ukudala iimeko okwakha umfanekiso inyama-ntathu. Isiphelo Isiphumo kukufumana uthotho imifanekiso, kwezibonakalayo kwi sinuses e izilayi ezahlukeneyo (layers). Le ndlela diagnostic nto ulwazi xa uzihlola umzimba inyama ithambile. Ngenxa yokuba em- le sinus igcwele inwebu yangaphakathi, yaye apho zitya yegazi ezininzi intlala, oogqirha bacebisa ukuba enze MRI kunokuba CT scan (ezikhethwayo nokuthelekelela kwamathambo).

Ezibonisa zokufunda

MRI amaninzi ezimiselweyo sinus ray isiqulatho ulwazi eliphantsi. Ingakumbi xa kukho urhano malunga yamathumba em- cranial. Kwakhona, le ndlela lophando lwenziwa kwiinkqubo ukudumba kwi latticed nesinqumka-emile kunye sinuses, njengokuba awukwazi kuqwalaselwa kwi ray. Kukho Yayibubungqina zilandelayo MRI yokuziphatha:

1. neoplasm okusolwayo. Oku alibhekiseli kuphela lweHo- sinus, kodwa amalungu ajikelezileyo zomzimba.
2. Le nobunzima ngeempumlo ukuphefumla yokungabikho utshintsho radiographic.
3. umothuko ngeempumlo okanye ukhakhayi yobuso.
4. Mgaqweni kwi isakhiwo sinuses.
5. ukuqanda Cyst kwi nasopharynx.
6. yintloko Unmotivated asizi ixesha elide.
7. pansinusitis okusolwayo okanye ukudumba nemingxuma aphezulu ngeempumlo, ubukho igazi ukuqanda zabo.

Kuhle ukukhumbula ukuba MRI kuthathwa ukuba indlela kakhulu ulwazi. Ngoko ke, ukuba kunokwenzeka, ukuze wenze le saveyi kukunika yokuqala kuthelekiswa nezinye iindlela nokuthelekelela le sinuses.

Kwezinye iimeko, MRI contraindicated?

Ngaphandle kwento yokuba scan sinuses kakhulu ulwazi kwezinye iimeko olu hlobo uphethwe contraindicated. Oku kungenxa yokuba enxulumene iindlela MRI, ezo zihamba kunye umthwalo iphiramidi ebonisa kwi eziphilayo. Izimo ukuba umfanekiso:

1. Ukukhulelwa. Enoba yobudala sokukhulelwa le ndlela phando akukhuthazwa ukuba abafazi abo komntwana. Kubalulekile ukukhumbula ukuba radiation magnetic kunokukhokelela ekubeni ezingaqhelekanga kwi olungekazalwa.
2. Zisanyisa. Ngaphandle kwento yokuba mfazi ke wazala umntwana, yena nikhumke ezivela kwisaveyi ezifana logama nje yena uncancisa umntwana. Ukuba imeko engxamisekileyo, MRI lwenziwa, nkqu ithuba zisanyisa. Kuyimfuneko ukuba ubisi ngokuphindaphindiweyo okucacileyo emva kwesifundo.
3. Ubukho impompo insulin, anokuba kwizigulane kunye nohlobo 1 diabetes.
4. Ukufumana umzimba womuntu zitho ezahlukeneyo (izinto zesinyithi, pacemakers, kuzwa).

Izimo Relative ziquka izifo zengqondo kunye luvo. Kule meko, umfanekiso akukhuthazwa ukuba izigulana bephelelwa kwaye akakwazi ukulawula iintshukumo zabo.

Technique MRI

Phambi kokuba MRI sinuses ayifuni uqeqesho olulodwa. Kwiimeko ezinqabe kakhulu, isigulane luyacetyiswa ukuba athathe ipilisi umthomalalisi eziya unokukunceda uphumle kamnandi. Amaninzi kuyimfuneko ukuba abantu bafumana uloyiko xa zibekwe kwindawo efakwe apha (bephelelwa) na. Le isigulane ilele phezu kwesingqengqelo, imilenze ezinzileyo kunye iirholithi ezikhethekileyo. amanyathelo ebefanele ukuba ulithathile, kuba awukwazi ukuhamba ngexesha le nkqubo. umsebenzi excess emzimbeni kuya kukhokelela kwiziphumo ezingachanekanga okanye MRI. Ngexesha le saveyi akakwazi ukuthetha, uthobe intloko yakhe. Le nkqubo ithatha malunga 10 imizuzu. Ngexesha unit isixhobosovavanyo lwemifanekiso ikhala ngendlela izandi uphawu ofana ivale. Kulo mzekelo umfanekiso luqokelelane sinuses e uqikelelo ezahlukeneyo. It idluliselwa kwi computer into igumbi elilandelayo. Le nkqubo ubukele umsebenzi wezempilo.

Kwezinye iimeko MRI le sinuses kunye umahluko?

Kwezinye iimeko, mishini eziqhelekileyo akwanelanga moshilongo. Emva koko ufake MRI kunye umahluko. Uphawu oluqhelekilyo kuphando olunjalo urhano iinkqubo somhlaza kwi sinuses okanye kufuphi nabo. Njengoko arhente nshita gadolinium ezisetyenzisiweyo. Le kuqaliswa kulo olujikeleza. Thelekisa iidayi Umthambo okanye umthambo kummandla ohlolisiswayo, nto leyo ebanceda nokuthelekelela.

iziphumo

Kuphela xa kukho imfuneko kufuneka aqeshe MRI sinuses. Yintoni le saveyi? Kokuhlaziya kwemifanekiso kuthatha ray okanye otolaryngologist. Ngokutsho MRI kunokubonwa ukungathobeli isakhiwo izihlunu, ithunzi ukuyilwa lwezidumbu, njl Ngenxa kule ndlela le ezimbi zilandelayo une ..:

1. Nezilonda sinus okanye kwizihlunu abakufuphi.
2. Ephula amathambo, ukungaqheleki zophuhliso.
3. Ukudumba skeletal system - osteomyelitis.
4. Neoplasms ye sinuses ngeempumlo kunye ukakayi yobuso.
5. Ukwenzakala.

Izinto eziluncedo ze MRI sinuses

Ekuqeshweni umfanekiso, izigulane ezininzi ubuza umbuzo: kutheni ungenzi-X-reyi endaweni impumlo? Eneneni, MRI uthathwa ukuba abe inkqubo ebiza ukuba wonke umntu akwazi ukufikelela. Eneneni, X-ray kwakhona likuvumela ukuba nomfanekiso-sinuses. Noko ke, zibuthe livakale umfanekiso lineqela iingenelo. Phakathi kwabo: ukukwazi ukubona zonke sinuses, umaleko ngu umaleko isixhobosovavanyo lwemifanekiso yonke imimandla yelo izakhiwo zeethishu le ndawo. Enye inzuzo yale ndlela kukunqongophala isidingo re-exposure komzimba.

sinuses MRI: ixabiso le nkqubo

Magnetic intlokoma umfanekiso - indlela survey, apho oko kunokwenzeka ukuba ajonge nayiphi indawo yomzimba. Umzekelo, esiswini okanye isifuba kwisisu, ingqondo. Kwiminyaka yakutshanje, kwiimeko kuyakrokreleka ngezifo kakhulu phecana eliphezulu nokuphefumla kucetyiswa ukwenza MRI sinuses. Ixabiso inkqubo ixhomekeke kummandla kunye ekliniki, ibanjwa imifanekiso. Iindleko avareji yale ndlela yokuhlola ukusukela engange-2 ukuya ku-6 amawaka.
