I-MRI ye-pancreas nesibindi kuyindlela ephumelelayo futhi efundisayo yokubona izitho zomzimba nokuthola ulwazi oluthembekile ngesimo sazo. Ibonisani i-MRI yesibindi ne-pancreas futhi uyini umehluko phakathi kwe-MRI ne-CT?
Ngosizo lwale teknoloji, kungenzeka ukuthola ubukhona bezinsimbi ezinama-volumetric ezingxenyeni zezitho futhi uqhubeke ngokuphathwa kwe-pathologies ngesikhathi. Ukusebenzisa i-MRI kukuvumela ukuthi wakhe isithombe esici-ntathu somzimba, njenge-scan scan yama-pancreas.
Lezi zindlela zokuhlola zihlukile komunye nomunye:
- izinga lokuzwela ngesikhathi sokuhlolwa;
- ngokuya ngemigomo yokusebenza.
I-tomography ehlanganisiwe ye-pancreas, ukuthola idatha, isebenzisa imisebe ye-x-ray, ngokungafani nomcabango we-magnetic resonance, lapho kusetshenziswa khona amandla kazibuthe ukwakha isithombe esici-ntathu sesitho esifunwayo.
I-Pancreatic CT ngokuqhathanisa, kanye ne-organ MRI, isetshenziselwa ukuthola i-pathologies ejwayelekile kakhulu, okuyiyona eyinhloko elandelayo:
- Umdlavuza
- Ukuba khona kwama-tumign benign kanye nama-cystic formations.
- Ukuchazwa kwamatshe emicekeni.
- Ukuba khona kwe-pancreatitis eyingozi.
- I-pancreatitis engapheli
Imvamisa, i-CT isetshenziselwa ukuqinisekisa noma ukuphikisa ukutholakala komdlavuza. Lokhu kungenxa yokuthi i-compact tomography inesisombululo cishe esilingana ne-ultrasound.
Enye yezinhlobonhlobo zale ndlela ubuchwepheshe be-multispiral (multislice, multilayer) computer tomography (MSCT). Lobu buchwepheshe bokuhlolwa bunolwazi kakhulu kune-ultrasound.
I-MRI noma i-CT scan ibekwa ngaphambi kokungenelela kokuhlinzwa okuhleliwe.
Izinzuzo nobubi be-MRI ngaphezu kwezinye izindlela
Lapho uqhathanisa izindlela ezahlukahlukene zokuxilonga, kwatholakala ukuthi ukucabanga kwe-magnetic resonance uyakwazi ukwedlula kakhulu ubuchwepheshe obufundisayo bokuxilonga izifo ezinjenge-CT, i-ultrasound ne-angiography ngemininingwane, ikakhulukazi uma i-magnetic resonance imaging magnetic resonance cholangiopancreatography isetshenziswa kanyekanye ukuthola idatha yesimo somzimba .
Inzuzo enkulu phezu kobunye ubuchwepheshe ukuthi i-MRI ayisebenzisi ama-x-ray ayingozi.
Umgomo wokuthola imininingwane usekwe ekusetshenzisweni kwamandla kazibuthe wenyukliya. Imininingwane etholakele icutshungulwa kusetshenziswa izinhlelo ezikhethekile zamakhompiyutha ezenziwa ekwakhiweni kwale mininingwane enezinhlangothi ezintathu zesitho esibukweni sekhompyutha.
Njengomphumela wokuvezwa kwezinsimu zamandla kazibuthe, ama-athomu e-hydrogen ayavuselelwa ezicutshini zomzimba futhi aqondaniswe nensimu yamandla, futhi idatha efundwayo ikuvumela ukuthi ufinyelele ukubonwa okuphezulu kwesitho ngesikhathi sokulungiswa kwedatha.
Ngenxa yokuthi inzwa ye-tomograph isendaweni ezungeze umzimba, udokotela uthola isithombe sicacile futhi siyisiqubu.
Okubi ngale ndlela izindleko zokuxilongwa.
Ukusetshenziswa kwe-MR tomography kwenza sikwazi ukubona ubukhona bezinguquko ezihlelekile kwezicubu zesitho esihloliwe, ukuphambuka kokujwayelekile esakhiweni kanye ne-pathologies okuholela ekuphanjukeni kwegazi okungahambi kahle.
Ngaphezu kwalokho, imininingwane etholakalayo isivumela ukuthi sisungule ubukhona noma ukungabikho kwe-ebalulekile ye-tumor izinqubo ezithweni zezicubu zomzimba.
Ukulungiselela kanye necebo le-pancreatic MRI
Kuthatha isikhathi esingakanani ukwenza izinqubo zokuxilonga? Isikhathi senqubo yokucwaninga cishe ihora elilodwa. Isikhathi silinganiselwa, ngoba isikhathi sesifundo singancika ekubumbeni kanye nenani lezendlalelo ezidingekayo.
Ngaphambi kokwenza inqubo, isiguli kufanele silungiselele ukuqaliswa kwayo ngokufanele.
Ukulungiselela ukuthola idatha ethembekile kudinga ukufezeka kwezidingo ezithile, okulandelayo:
- Isiguli kufanele sisuse yonke imikhiqizo yensimbi emzimbeni.
- Thatha isikhundla somzimba osifunayo. Lapho ethola amanyikwe, ekhomba izinqubo ze-pathological kanye nokuvuvukala kwamanyikwe, isiguli kufanele sithathe ukuma okufanele komzimba, okulele kuso endizeni ekhethekile, ikhanda lakhe liqonde endaweni efanele. Enye yezimfuneko zokuthola imininingwane ethembekile mayelana nesimo se-pancreas ukungasebenzi.
- Ukwethulwa kwento ekhethekile ehlukanisayo emthanjeni wesiguli ukukuqongelela kwizicubu zesikhumba.
Ngaphambi kokuthola ukuthi kukhona okungahambi kahle gland, kuyadingeka ukukhipha uhlelo lokugaya ukudla ngangokunokwenzeka.
Ngale njongo, izidingo ezilandelayo kumele zihlangatshezwe:
- ngosuku olulodwa ngaphambi kwenqubo, izithako ezinosawoti kanye nezitsha ezinosawoti kufanele zingafakwa ngokuphelele ekudleni;
- ungaphuzi utshwala, kanye nemithi equkethe i-ethyl alcohol;
- ukungaqhubeki ngaphambi kokuhlolwa kwezinqubo ezibandakanya ukwethulwa kwesilinganiso esiphikisayo emgodini we-pancreatic duct;
- Kwenqatshelwe ukuphuza ikhofi netiye ngosuku ngaphambi kwenqubo.
I-MRI ayivunyelwe kubantu abafake ama-pacemaker nezinye izinto zensimbi, ezihambisana nokuchayeka endaweni enamandla kazibuthe.
Isithombe se-anatomical sitholwe yi-magnetic resonance therapy
Ngenxa yokutholakala kwamathuba amaningi, le nqubo ikuvumela ukuthi uthole imininingwane ephelele ye-anatomy yesitho, ngesimo sezicubu zayo nemikhonto. Lesi sithombe siveza ukwakheka kwamatshe emiseleni kanye nokuba khona kwamagama amancane emigodini eyandisiwe.
Ubuchwepheshe bokuthola imininingwane bukuvumela ukuthi ukhombe ubukhona bokuvuvukala esitho, futhi ukunemba kwayo kufinyelela kuma-97%. Lokhu kunemba kutholakala lapho kutholwa ama-pathologies omzimba kanye nomsila we-gland.
Ukusetshenziswa kokuthwebula uzibuthe kwenza kube lula ukubona ama-neoplasms emzimbeni nomsila osayizi ngisho kufika ku-2 cm ubukhulu.
Ukuchazwa kwe-neoplasm ye-pathological kufaka izinto ezilandelayo:
- Usayizi wokugxila kwe-pathology.
- Uhlobo lwe-neoplasm.
- Isimilo semibango.
- Ukuqina kwesiginali, okuvumela ukunquma ubungako bezicubu endaweni yokwakheka kokugxilwa kwe-pathology. Ngokuqina kwesiginali, kulula kakhulu ukwahlukanisa isimila kusuka kuyi-pancreatic cyst. Lesi sici senza kube lula kakhulu ukunquma uhlobo lwe-pathology kunokuba, ngokwesibonelo, ngokuhlolwa kwe-ultrasound.
Ubuchwepheshe be-magnetic resonance technology buyenza bakwazi ukubona isimo samaphakethe nezikhwama eziseduze kwama-pancreas. Ngakho-ke, ukunqwabelana koketshezi, ubomvu noma igazi kunqunywe. Ngaphezu kwalokho, ubuchwepheshe buveza ukuba khona kwama-metastases okungenzeka ekwakheni inqubo ye-oncological.
Ngaphandle kokuba khona kokuthembela okuphezulu ngesikhathi sokuhlolwa kwamanyikwe yi-MRI, ezinye izivivinyo ezengeziwe ze-elebhu ziyadingeka ukucacisa ukutholakala kwale nkinga.
Ngokungezeleleki ekutholeni isifo esisitholayo, kungadingeka usebenzise ezinye izifundo ezingelusizo ezichaza isithombe salesi sifo.
Imininingwane mayelana ne-pancreatic MRI inikezwe kuvidiyo ekulesi sihloko.
