Ngokuphucuka kolwazi lwabantu ngempilo kunye nokusetyenziswa ngokubanzi kwe-CT ejikelezayo yedosi ephantsi kwiimvavanyo zomzimba ngokubanzi, kufumaneka amaqhuqhuva amaninzi emiphungeni ngexesha lovavanyo lomzimba. Nangona kunjalo, umahluko kukuba kwabanye abantu, oogqirha basaya kubacebisa abaguli ukuba benze uvavanyo lwe-CT oluphuculweyo. Akuphelelanga apho, i-PET-CT iye yangena kancinci kancinci kwicandelo lokubona komntu wonke kwiklinikhi. Yintoni umahluko phakathi kwabo? indlela yokukhetha?
Oko kubizwa ngokuba yi-CT ephuculweyo kukufaka iyeza eliqulethe i-iodine elivela emthanjeni liye emithanjeni yegazi uze emva koko wenze i-CT scan. Oku kunokufumanisa izilonda ezingafumanekiyo kwi-CT scans eziqhelekileyo. Kunokufumanisa nokunikezelwa kwegazi kwezilonda kwaye kwandise inani lokuxilongwa kwesifo kunye neendlela zonyango. Ubungakanani bolwazi olufanelekileyo olufunekayo.
Ngoko ke loluphi uhlobo lwezilonda ezifuna i-CT ephuculweyo? Enyanisweni, i-CT scan ephuculweyo ibaluleke kakhulu kwii-nodules eziqinileyo ezingaphezulu kwe-10 mm okanye ezinkulu ze-hilar okanye ze-mediastinal masses.
Ngoko ke yintoni iPET-CT? Ngamafutshane, iPET-CT yindibaniselwano yePET kunye neCT. I-CT yiteknoloji yetomography ekwikhompyutha. Olu vavanyo ngoku lwaziwa kakhulu yintsapho nganye. Kwakamsinya nje umntu elele phantsi, umatshini uyaluskena, aze azi ukuba intliziyo, isibindi, ipleyini, imiphunga kunye nezintso zinjani.
Igama lesayensi le-PET yi-positron emission tomography. Ngaphambi kokuba wenze i-PET-CT, wonke umntu kufuneka afake i-arhente ekhethekileyo yokungafani ebizwa ngokuba yi-18F-FDGA, egama layo lipheleleyo lingu-"chlorodeoxyglucose". Ngokungafaniyo ne-glucose eqhelekileyo, nangona inokungena kwiiseli ngee-glucose transporters, igcinwa kwiiseli kuba ayinakuthatha inxaxheba kwiimpendulo ezilandelayo.
Injongo ye-PET scan kukuvavanya amandla eeseli ezahlukeneyo okusebenzisa i-glucose, kuba i-glucose yeyona mthombo wamandla obalulekileyo kwi-metabolism yomntu. Okukhona i-glucose ityiwa kakhulu, kokukhona amandla e-metabolism eqina. Enye yeempawu ezibalulekileyo ze-malignant tumors kukuba inqanaba le-metabolism liphezulu kakhulu kunelezicubu eziqhelekileyo. Ngamafutshane, ii-malignant tumors "zitya i-glucose engakumbi" kwaye zifunyanwa lula yi-PET-CT. Ke ngoko, kucetyiswa ukwenza i-PET-CT yomzimba wonke kuba ixabisa kancinci. Eyona ndima inkulu ye-PET-CT kukufumanisa ukuba i-tumor itshintshile na, kwaye uvakalelo lunokuba phezulu ukuya kwi-90% okanye ngaphezulu.
Kwizigulane ezinee-nodules zemiphunga, ukuba ugqirha ugweba ukuba i-nodule inobungozi kakhulu, kuyacetyiswa ukuba isigulane sihlolwe i-PET-CT. Nje ukuba i-tumor ifunyaniswe ukuba i-metastasis, inxulumene ngokuthe ngqo nonyango olulandelayo lwesigulana, ngoko ke ukubaluleka kwe-PET-CT akunakugqithiswa. Kwaye sisifaniso. Esi sesinye sezizathu eziphambili ze-PET-CT. Kukho olunye uhlobo lwesigulana oludinga i-PET-CT: xa kunzima ukugweba ii-nodules ezinobungozi nezinobungozi okanye izilonda ezihlala kwindawo, i-PET-CT ikwayindlela encedisayo yokuxilonga. Ngenxa yokuba izilonda ezinobungozi “zitya i-glucose eninzi.”
Lilonke, i-PET-CT inokufumanisa ukuba kukho ithumba na kwaye ingaba ithumba liye lasasazeka emzimbeni wonke, ngelixa i-CT ephuculweyo isetyenziswa rhoqo ekuxilongeni nasekunyangeni iithumba ezinkulu zemiphunga kunye neethumba eziphakathi. Kodwa nokuba loluphi uhlobo lovavanyo, injongo kukunceda oogqirha benze izigqibo ezingcono ukuze banike izicwangciso zonyango ezingcono kwizigulana.

Njengoko sonke sisazi, uphuhliso lweshishini lemifanekiso yezonyango alunakwahlulwa kuphuhliso lwezixhobo zonyango ezininzi - ii-contrast agent injectors kunye nezinto ezisetyenziswayo ezixhasayo - ezisetyenziswa kakhulu kweli candelo. E-China, edume ngeshishini layo lokuvelisa, kukho abavelisi abaninzi abadumileyo ekhaya nakwamanye amazwe ngokuvelisa izixhobo zemifanekiso yezonyango, kuqukaI-LnkMedUkususela oko yasekwa, iLnkMed ibigxile kwicandelo lee-injectors ze-contrast agents ezinoxinzelelo oluphezulu. Iqela lobunjineli leLnkMed likhokelwa yiPh.D. enamava angaphezu kweminyaka elishumi kwaye ibandakanyeka kakhulu kuphando nophuhliso. Phantsi kwesikhokelo sakhe,I-CT single head injector,I-CT double head injector,I-MRI contrast agent injectorkunyeI-Angiography yoxinzelelo oluphezulu lwe-contrast agent injectorZenzelwe ezi mpawu zilandelayo: umzimba oqinileyo nomncinci, ujongano lokusebenza olulula nolukrelekrele, imisebenzi epheleleyo, ukhuseleko oluphezulu, kunye noyilo oluhlala ixesha elide. Singabonelela ngeesirinji kunye neetyhubhu ezihambelana nezo mpawu zidumileyo zee-injectors ze-CT, MRI, DSA Ngenxa yesimo sabo sengqondo esinyanisekileyo kunye namandla abo obuchwephesha, bonke abasebenzi be-LnkMed bayanimema ngokunyanisekileyo ukuba nize nihlole iimarike ezininzi kunye.
