I-MRI defecography isebenzisa umshini we-MRI ukuze ufumane ulwazi malunga nokusebenza kwemisipha yomgangatho wakho weplavic ukuze uqonde ukuba kutheni unokuba neengxaki ezihambayo. Olu vavanyo lugqirha ugqirha wakho ukuba aqonde kangcono indlela i-rectum kunye nezinye izitho zeplavic zisebenza ngayo (okanye zisebenza ngokungasebenzi) njengoko uphuma kwisitulo.
Njengazo zonke i-MRIs, i-MRI defecography isebenzisa amagagasi omsakazo kunye namagnet ukuba athathe imifanekiso yeethambo ezincinci zezitho zangaphakathi.
Xa i-MRI Defecography isetyenziswa?
I-MRI defecography yinkqubo engaqhelekanga kwaye akukho zakhiwo ezininzi apho inkqubo yenziwa khona. Nangona kunjalo, xa ikhona, inokunika inkcazelo yokuxilonga malunga nale miqathango yempilo. Gcina ukhumbule ukuba ezininzi zezi meko zifunyaniswa ngokudibanisa iimvavanyo kunye neengxelo zakho zempawu kunye nembali yonyango.
- Ukuhla kwesifo se-perineal syndrome (ubuthathaka kunye nokuwa kweentloko ze-pelvic)
- Faka i-Enterocele (i-bulging ye-intsile encinci kwi-vaginal kunye ne-rectum)
- Dyssynergic defecation
- Ukungabikho kwamaFecal
- I-Rectocele (i-bulging yodonga lwe-rectum ukuya kwisini)
MRI Defecography Versus Defecography
I- defecography yendabuko isebenzisa ii-X-ray ukuvavanya isizathu esichaphazelekayo ngenxa yokuphazamiseka kwe-defecation. I-MRI defecography kucatshangelwa ukuba inikezele ngolwazi olunzulu malunga nendlela izitho ezahlukahlukeneyo (kubandakanywa ne-anal sphincter, i-bladder, intombazana encinci, isisu, kunye nesisini) kwi-pelvis ekusebenzisaneni ngexesha lokunyakaza kwebilini.
Ukongezelela, ukusetyenziswa kwe-MRI phezu kwe-X-ray kukukhusela kwi-radiation exposure.
Kwixesha elidlulileyo, i-MRI defecography yayinganiselwe ukuba kufuneka ubeke phantsi kwenkqubo, engakhange inikezele ngolwazi oluchanekileyo malunga nento eyenzeka ngokwenene ngexesha lokunyakaza. I-MRIs evulekileyo isele ikhona kwinkqubo, ngaloo ndlela ikuvumela ukuba uhlale ungagqibekanga kwaye ugqirha wakho ukuba abone ngexesha lokwenene okwenzekayo ngomzimba wakho xa usichaza.
Ngakolunye uhlangothi, i-defecography ibonakala njengendleko eninzi, iyabonakala kakhulu kwaye ilula ukuqhuba.
Njengomgaqo jikelele wesohlwayo, i-MRI defecography ingaba vavanyo oluphezulu xa utyando lusetyenziswa njengonyango olunokwenzeka kwiingxaki zakho zokuhlambela.
Oko Uya Kufumana
Unokukhululeka ukuba ufunde ukuba ngokungafani ne- colonoscopy , akuyi ku funeka ufumane i-prep yokucoca imbobo ngaphambi kokuba kuqeshwe. Akunakufuneka ukhawuleze. Njengazo zonke i-MRIs, akukho sinyithi kuvunyelwe kwaye uya kubuzwa malunga nantoni na izinto zetsimbi ezingase zibe ngaphakathi emzimbeni wakho. Uvavanyo aluba buhlungu, nangona abanye abantu buchaza ngokunyanzelisa okanye ukucima. Uvavanyo lungaba lukhulu, ngokubetha umsindo njengoko umatshini ethatha imifanekiso.
I-gel, ezaliswe isisombululo esahlukileyo, iya kufakwa ngenyameko kwi-rectum yakho. (Ukuba ungowesifazana, isisombululo singeniswa kwisisu sakho.) Ukuba unemiMRI evulekile, uya kuhlala ngexesha loviwo, ngaphandle koko uya kulala phantsi. Into ebizwa ngokuthi "i-coil imaging", enezixhobo, iya kuguqulwa kwi-pelvis yakho xa uhleli, okanye ubeke njengengubo kwisisu sakho okanye ngasemva.
Ngethuba le nkqubo uza kunikwa izikhokelo malunga nokuba ungabamba nini okanye usigxothe isisombululo.
Unokucelwa ukuba 'ubuthwale phantsi,' okanye ulungele ukukhulula indawo yakho yeplavic.
Inkqubo ngokwayo ithatha malunga nemizuzu engama-30.
