Ukuqaliswa kwe-CT, i-Enhanced Computed Tomography (CECT) kunye ne-PET-CT

Ngokuphuculwa kolwazi lwempilo yabantu kunye nokusetyenziswa ngokubanzi kwedosi ephantsi ye-spiral CT kwiimviwo zomzimba jikelele, amaqhuqhuva amaninzi emiphunga afunyanwa ngexesha lokuhlolwa komzimba. Nangona kunjalo, umahluko kukuba kwabanye abantu, oogqirha basaza kucebisa izigulana ukuba zenze uvavanyo lokuphucula i-CT. Ayisiyiyo loo nto kuphela, i-PET-CT ithe ngokuthe ngcembe yangena kwinkalo yombono yomntu wonke kuqheliselo lwezonyango. Yintoni umahluko phakathi kwazo? njani ukukhetha?

Oko kubizwa ngokuba yi-CT ephuculweyo kukutofa iyeza le-agent equlethe i-iodine echaseneyo ukusuka kumthambo ukuya kumthambo wegazi kwaye emva koko wenze i-CT scan. Oku kunokufumanisa izilonda ezingafumanekiyo kwi-CT scans eziqhelekileyo. Iyakwazi nokumisela ukunikezelwa kwegazi kwezilonda kunye nokwandisa inani lokuxilongwa kwesifo kunye nokukhethwa kwonyango. isixa solwazi olufanelekileyo olufunekayo.

Ke luhlobo luni lwezilonda ezifuna ukuphuculwa kweCT? Ngapha koko, ukuskena okuphuculweyo kwe-CT kuxabiseke kakhulu kumaqhuqhuva aqinileyo ngaphezulu kwe-10 mm okanye ihilar enkulu okanye ubunzima be mediastinal.

Ke yintoni i-PET-CT? Ukubeka nje, i-PET-CT yindibaniselwano ye-PET kunye ne-CT. I-CT yiteknoloji ye-tomography yekhompyutha. Olu vavanyo luyaziwa ngoku kuwo wonke umzi. Ngokukhawuleza xa umntu elele phantsi, umatshini uyawuhlola, kwaye unokwazi ukuba intliziyo, isibindi, udaka, imiphunga kunye nezintso zikhangeleka njani.

Igama lenzululwazi le-PET yi-positron emission tomography. Phambi kokwenza i-PET-CT, wonke umntu kufuneka atofe iarhente yomahluko ekhethekileyo ebizwa ngokuba yi-18F-FDGA, egama layo elipheleleyo lingu-“chlorodeoxyglucose”. Ngokungafaniyo ne-glucose eqhelekileyo, nangona inokungena kwiiseli ngokusebenzisa abathuthi be-glucose, igcinwa kwiiseli ngenxa yokuba ayikwazi ukuthatha inxaxheba kwiimpendulo ezilandelayo.

Injongo ye-PET scan kukuvavanya amandla eeseli ezahlukeneyo okutya iswekile, kuba iswekile ngowona mthombo wamandla obalulekileyo osetyenziswa ngabantu. Okukhona iswekile igalelwe, kokukhona amandla ometabolism anamandla. Enye yeempawu ezibalulekileyo zamathumba anobungozi kukuba inqanaba le-metabolic liphezulu kakhulu kunelo lezicubu eziqhelekileyo. Ukubeka nje, izicubu ezinobungozi "zidla i-glucose eninzi" kwaye zifunyanwa lula yi-PET-CT. Ke ngoko, kuyacetyiswa ukuba wenze i-PET-CT yomzimba wonke kuba ineendleko ezingaphezulu. Indima enkulu ye-PET-CT kukufumanisa ukuba i-tumor ine-metastasized, kwaye uvakalelo lunokuphakama njenge-90% okanye ngaphezulu.

Kwizigulana ezinamaqhuqhuva emiphungeni, ukuba ugqirha ugqiba kwelokuba iqhuqhuva liyingozi kakhulu, kucetyiswa ukuba umguli enze uvavanyo lwePET-CT. Emva kokuba i-tumor ifunyenwe ukuba i-metastasized, ihambelana ngokuthe ngqo nonyango olulandelayo lwesigulane, ngoko ke ukubaluleka kwe-PET-CT ayikwazi ukugqithiswa. Kwaye sisikweko. Esi sesinye sezizathu eziphambili ze-PET-CT. Kukho olunye uhlobo lwesigulane olufuna kwakhona i-PET-CT: xa kunzima ukugweba ama-nodules anobungozi kunye ne-malignant okanye izilonda ezihlala kwindawo, i-PET-CT nayo ibaluleke kakhulu indlela yokuxilongwa. Kuba izilonda ezinobungozi "zitya iswekile eninzi."

Lilonke, i-PET-CT inokugqiba ukuba ngaba kukho i-tumor kunye nokuba i-tumor i-metastasized kuwo wonke umzimba, ngelixa i-CT ephuculweyo isoloko isetyenziselwa ukuxilongwa kunye nonyango lwamathumba amakhulu emiphunga kunye ne-mediastinal tumors. Kodwa kungakhathaliseki ukuba luhlobo luni loxilongo, injongo kukunceda oogqirha benze izigqibo ezilunge ngakumbi ukuze babonelele ngezicwangciso ezilunge ngakumbi zonyango kwizigulana.

Njengoko sonke siyazi, ukuphuhliswa kwemboni yezobuchwephesha zonyango ayinakuhlukaniswa nokuphuhliswa koluhlu lwezixhobo zonyango - ii-injection ze-agent echaseneyo kunye nezinto ezixhasayo - ezisetyenziswa kakhulu kule ndawo. E-China, edume ngoshishino lwayo lokuvelisa, baninzi abavelisi abadumileyo ekhaya nakwamanye amazwe ngokuveliswa kwezixhobo zonyango zonyango, kuquka.LnkMed. Ukusukela ekusekweni kwayo, i-LnkMed ibigxile kwintsimi yee-ejenti zokuchasa ngoxinzelelo oluphezulu. Iqela lobunjineli be-LnkMed likhokelwa yi-Ph.D. uneminyaka engaphezu kweshumi yamava kwaye uzibandakanye nzulu kuphando nophuhliso. Phantsi kokhokelo lwakhe, iCT isitofu sentloko enye,CT isitofu sentloko kabini,Isitofu se-agent ye-MRI yokuchasana, kwayeI-Angiography yoxinzelelo oluphezulu lwe-ejenti yokuchasaziyilwe ngezi mpawu: umzimba owomeleleyo noxineneyo, ujongano olufanelekileyo nolukrelekrele lokusebenza, imisebenzi epheleleyo, ukhuseleko oluphezulu, kunye noyilo oluhlala ixesha elide. Sinokubonelela ngeesirinji kunye netyhubhu ehambelana nezo mpawu zidumileyo ze-CT, iMRI, ii-injection ze-DSA Ngesimo sabo sengqondo esinyanisekileyo kunye namandla obuchwephesha, bonke abasebenzi be-LnkMed bayakumema ngokunyanisekileyo ukuba uze uhlolisise iimarike ezininzi kunye.
