Isingeniso se-CT, i-Enhanced Computed Tomography (CECT) kanye ne-PET-CT

Ngokuthuthuka kokuqwashisa ngempilo yabantu kanye nokusetshenziswa kabanzi kwe-CT ejikelezayo yomthamo ophansi ekuhlolweni ngokomzimba okuvamile, kutholakala amaqhubu amaningi emaphaphu ngesikhathi sokuhlolwa ngokomzimba. Kodwa-ke, umehluko uwukuthi kwabanye abantu, odokotela basazoncoma iziguli ukuthi zenze ukuhlolwa kwe-CT okuthuthukisiwe. Akukhona lokho kuphela, i-PET-CT iye yangena kancane kancane emkhakheni wokubona wawo wonke umuntu emtholampilo. Uyini umehluko phakathi kwawo? Ungakhetha kanjani?

I-CT ethuthukisiwe iwukufaka umuthi we-contrast oqukethe i-iodine ovela emthanjeni uye emthanjeni wegazi bese wenza i-CT scan. Lokhu kungabona izilonda ezingatholakali kuma-CT scan ajwayelekile. Kungaphinde kunqume ukutholakala kwegazi kwezilonda futhi kwandise inani lokuxilongwa kwesifo kanye nezinketho zokwelapha.

Ngakho-ke hlobo luni lwezilonda ezidinga i-CT ethuthukisiwe? Eqinisweni, ukuskena kwe-CT ethuthukisiwe kubaluleke kakhulu kuma-nodule aqinile angaphezu kwama-10 mm noma amakhulu ama-hilar noma ama-mediastinal masses.

Ngakho-ke iyini i-PET-CT? Kalula nje, i-PET-CT iyinhlanganisela ye-PET ne-CT. I-CT ubuchwepheshe be-tomography obusebenzisa ikhompyutha. Lokhu kuhlolwa sekuyaziwa yiwo wonke umndeni. Lapho nje umuntu elele phansi, umshini uyawuskena, futhi bayakwazi ukuthi inhliziyo, isibindi, ubende, amaphaphu nezinso zibukeka kanjani.

Igama lesayensi le-PET yi-positron emission tomography. Ngaphambi kokwenza i-PET-CT, wonke umuntu kumele afake i-ejenti ekhethekile yokuhlukanisa ebizwa ngokuthi i-18F-FDGA, egama layo eliphelele lingu-“chlorodeoxyglucose”. Ngokungafani ne-glucose evamile, nakuba ingangena emaselini ngokusebenzisa abathuthi be-glucose, igcinwa emaselini ngoba ayikwazi ukuhlanganyela ekuphenduleni okulandelayo.

Inhloso ye-PET scan ukuhlola ikhono lamaseli ahlukene lokudla i-glucose, ngoba i-glucose ingumthombo wamandla obaluleke kakhulu we-metabolism yomuntu. Uma i-glucose igwinywa kakhulu, ikhono le-metabolic liqina. Esinye sezici ezibalulekile zama-tumors amabi ukuthi izinga le-metabolic liphakeme kakhulu kunelezicubu ezivamile. Kalula nje, ama-tumors amabi "adla i-glucose eningi" futhi atholakala kalula yi-PET-CT. Ngakho-ke, kunconywa ukwenza i-PET-CT yomzimba wonke ngoba ingabizi kakhulu. Indima enkulu ye-PET-CT ukunquma ukuthi isimila sisakazeke yini, futhi ukuzwela kungaba phezulu njengo-90% noma ngaphezulu.

Ezigulini ezinezimbotshana zamaphaphu, uma udokotela enquma ukuthi imbotshana iyingozi kakhulu, kunconywa ukuthi isiguli sihlolwe i-PET-CT. Uma isimila sitholakale sisakazeke, sihlobene ngqo nokwelashwa okulandelayo kwesiguli, ngakho-ke ukubaluleka kwe-PET-CT akunakuphikiswa. Futhi kuyisifaniso. Lesi ngesinye sezizathu eziyinhloko ze-PET-CT. Kukhona olunye uhlobo lwesiguli oludinga i-PET-CT: lapho kunzima ukwahlulela izimbotshana ezingenabungozi nezimbi noma izilonda ezihlala endaweni, i-PET-CT nayo iyindlela yokuxilonga ewusizo ebaluleke kakhulu. Ngoba izilonda ezibi “zidla ushukela omningi.”

Sekukonke, i-PET-CT inganquma ukuthi kukhona yini isimila nokuthi isimila sesisabalele emzimbeni wonke, kuyilapho i-CT ethuthukisiwe ivame ukusetshenziswa ekuxilongeni nasekuphatheni izimila ezinkulu zamaphaphu kanye nezimila eziphakathi nendawo. Kodwa kungakhathaliseki ukuthi hlobo luni lokuhlolwa, inhloso ukusiza odokotela benze izinqumo ezingcono ukuze banikeze izinhlelo zokwelapha ezingcono iziguli.

Njengoba sonke sazi, intuthuko yemboni yezithombe zezokwelapha ayihlukaniseki ekuthuthukisweni kochungechunge lwemishini yezokwelapha - ama-injector agent injector kanye nezinto ezisetshenziswayo ezisekelayo - ezisetshenziswa kabanzi kulo mkhakha. EShayina, edume ngemboni yayo yokukhiqiza, kunabakhiqizi abaningi abadumile ekhaya nakwamanye amazwe ngokukhiqiza imishini yezithombe zezokwelapha, okuhlanganisaI-LnkMedKusukela yasungulwa, i-LnkMed ibilokhu igxile emkhakheni wama-injectors anamandla aphezulu okucindezela. Ithimba lobunjiniyela le-LnkMed liholwa yi-Ph.D. elinolwazi olungaphezu kweminyaka eyishumi futhi lihileleke kakhulu ocwaningweni nasekuthuthukisweni. Ngaphansi kwesiqondiso sakhe, i-Umjovo wekhanda elilodwa le-CT,Umjovo wekhanda eliphindwe kabili we-CT,Umjovo we-MRI contrast agent, futhiI-Angiography high-pressure contrast agent injector injectorzenzelwe lezi zici: umzimba oqinile futhi ohlangene, isikhombimsebenzisi sokusebenza esilula nesihlakaniphile, imisebenzi ephelele, ukuphepha okuphezulu, kanye nomklamo ohlala isikhathi eside. Singaphinde sinikeze amasirinji namashubhu ahambisana nalawo mabhrendi adumile e-CT, MRI, DSA injectors Ngenxa yesimo sabo sengqondo esiqotho kanye namandla ochwepheshe, bonke abasebenzi be-LnkMed bakumema ngobuqotho ukuthi nize nizohlola izimakethe ezengeziwe ndawonye.
