“Imidiya ephikisanayo ibaluleke kakhulu ekubalukeni okwengeziwe kobuchwepheshe bokuthwebula izithombe,” kusho uDushyant Sahani, MD, ochungechungeni lwamavidiyo asanda kuxoxwa noJoseph Cavallo, MD, MBA.
Ku-computed tomography (CT), i-magnetic resonance imaging (MRI) kanye ne-positron emission tomography i-computed tomography (PET/CT), uDkt. Sahani uthe ama-contrast agents asetshenziswa ezivivinyweni eziningi ze-cardiovascular imaging kanye ne-oncology imaging eminyangweni yezimo eziphuthumayo.
“Ngingathi amaphesenti angama-70 kuya kwangu-80 okuhlolwa ngabe awazange asebenze kahle ukube besingazisebenzisi lezi zinto zokulinganisa ezisezingeni eliphezulu esinazo,” kuphawula uDkt. Sahani.
UDkt. Sahani wanezela ngokuthi ama-contrast agents abalulekile ekuthathweni kwezithombe okuthuthukisiwe. Ngokusho kukaDkt. Sahani, ukuthwebula izithombe okuxubile noma okungokwenyama akukwazi ukwenziwa ngaphandle kokusebenzisa ama-tracer e-fluorodeoxyglucose (FDG) ekuthwebuleni izithombe ze-PET/CT.
UDkt. Sahani waphawula ukuthi abasebenzi be-radiology yomhlaba wonke “basebasha kakhulu,” ephawula ukuthi ama-contrast agents asiza ukulinganisa insimu yokudlala, anikeze ukwesekwa kokuxilonga kubahlinzeki bokudlulisela kanye nokwenza kube lula ukuthola imiphumela emihle yeziguli.
“Imidiya ye-Contrast yenza lezi zithombe zibe bukhali. Uma ususa i-contrast agent kulezi zindlela zobuchwepheshe eziningi, (wena) uzobona umehluko omkhulu endleleni ukunakekelwa okunikezwa ngayo (kanye) nezinselele zokuxilonga kanye nokuhlonza okungalungile,” kugcizelela uDkt. Sahani. “[Uzobona futhi] ukwehla okukhulu kokuthembela kubuchwepheshe bokuthwebula izithombe.
Ukuntuleka kwamuva kwama-contrast agents kugqamisa indlela odokotela be-radiology kanye nochwepheshe bezempilo abathembele ngayo kula ma-agents ukuze basize ekwenzeni ukuxilongwa okufika ngesikhathi kanye nezinqumo zokwelashwa kweziguli. Ngenkathi uDkt. Sahani ebukeze ukusetshenziswa kwamaphakethe amaningi okuthatha izithombe ukunciphisa imfucuza yemidiya yokungafani kanye nokusetshenziswa okwandisiwe kwe-multi-energy kanye ne-spectral CT ukunciphisa umthamo wokungafani, ukuqapha okuqhubekayo kanye nokwehlukahluka kwama-contrast agents kwakuyizifundo ezibalulekile ezifundwe.
“Kudingeka ube nesibindi sokuhlola ukunikezwa kwakho, udinga ukushintshashintsha imithombo yakho yokunikezwa, futhi udinga ukuba nobudlelwano obuhle nabathengisi bakho.” Lobo budlelwano bubonakala ngempela uma udinga usizo lwabo, “kuphawula uDkt. Sahani.
Njengoba uDkt. Sahani eshilo, kubaluleke kakhulu ukugcina ubudlelwano obuhle nabahlinzeki bezinto zokwelapha nokukhuthaza ukuhlukahluka kwemithombo yokuhlinzeka.I-LnkMedfuthi ingumhlinzeki ogxile emkhakheni wezokwelapha. Imikhiqizo eyikhiqizayo isetshenziswa kanye nomkhiqizo oyinhloko walesi sihloko - i-contrast media, okungukuthi, ama-injector e-contrast media anomfutho ophezulu. I-contrast agent ifakwa emzimbeni wesiguli ngayo ukuze isiguli sikwazi ukuhlolwa okulandelayo. I-LnkMed inekhono lokukhiqiza uhla oluphelele lwe-i-injector yemidiya yokungafani ecindezeleke kakhuluimikhiqizo:I-CT single head contrast media injector, I-CT double head contrast media injector, Umjovo wemidiya yokungafani kwe-MRIfuthiI-Angiography high pressure contrast media injector (I-DSA high pressure contrast media injector). I-LnkMed inethimba elinolwazi olungaphezu kweminyaka eyi-10. Ithimba eliqinile le-R&D kanye nelokuklama kanye nohlelo oluqinile lokulawula ikhwalithi nakho kuyizizathu ezibalulekile zokuthi kungani imikhiqizo ye-LnkMed ithengiswa kahle ezibhedlela ezinkulu ekhaya nakwamanye amazwe. Singaphinde sinikeze amasirinji namapayipi alungiselelwe wonke amamodeli amakhulu okufaka injector (njenge-Bayer Medrad, i-Bracco, i-Guerbet Mallinckrodt, i-Nemoto, i-Sino, ne-Seacrowns). Silangazelela ukubonisana nawe.
"Uma ubheka umthelela we-COVID-19 emisebenzini yokunakekelwa kwempilo, kugcizelelwa kakhulu ekusebenzeni, okungeyona nje kuphela ngokusebenza kahle kodwa futhi nangezindleko. Zonke lezi zici zizodlala indima ekukhethweni nasekukhokhweni kwezivumelwano zama-contrast agents kanye nendlela asetshenziswa ngayo emtholampilo ngamunye... Zidlale indima enkulu ezinqumweni ezifana nemithi ejwayelekile," kusho uDkt. Sahani.
Isidingo semidiya yokuqhathanisa asikahlangatshezwa. UDkt. Sahani uphakamise ukuthi ezinye izindlela zokusebenzisa ama-iodine contrast agents zingathuthukisa amakhono obuchwepheshe obuthuthukisiwe bokuthwebula izithombe.
“Ngasohlangothini lwe-CT, sibone intuthuko enkulu ekutholeni nasekuvuseleleni izithombe nge-spectral CT kanye ne-CT yokubala i-photon, kodwa inani langempela lalobu buchwepheshe lisezintweni ezintsha zokuhlukanisa,” kusho uDkt. Sahani. “… Sifuna izinhlobo ezahlukene zama-agent, ama-molecule ahlukene angahlukaniswa kusetshenziswa ubuchwepheshe be-CT obuthuthukisiwe. Ngemuva kwalokho singacabanga ngamandla aphelele alobu buchwepheshe obuthuthukisiwe.”
