Ucwaningo Lukhombisa Izinhlelo Zokujova ze-MRI kanye ne-CT Ezisetshenziswa Kaningi Zithuthukisa Ukusebenza Kahle Futhi Zinciphise Izindleko

Muva nje, i-Scientific Reports ishicilele ucwaningo lokuqhathanisa olungase luhlaziywe ukusebenza kwezokwelapha kokusetshenziswa okuningi (MI) vs ukusetshenziswa okukodwa (SI)Umjovo wokungafani kwe-MRIs, okunikeza ukuqonda okubalulekile kwezikhungo zezithombe lapho kukhethwa izinhlelo zokujova. Ucwaningo luqokomisa ukuthi ama-injector asetshenziswa kaningi anikeza izinzuzo ezibalulekile ekusebenzeni kahle, ukusetshenziswa kokuqhathanisa, kanye nokulawula izindleko.

Ukusebenza Kahle Okuthuthukisiwe

Ucwaningo lwenziwe eRadboud University Medical Center eNetherlands futhi lwaluhlanganisa iziguli ezingaphezu kuka-300 ezazithweswa ama-MRI contrast-enhanced scan. Lwahlukaniswe ngezigaba ezimbili: izinsuku zokuqala eziyi-10 kusetshenziswa ama-multi-use MRI injectors (MI) kanye nezinsuku ezilandelayo eziyi-10 kusetshenziswa ama-single-use injectors (SI). Imiphumela ibonise ukuthi isikhathi sokulungiselela esimaphakathi sezinhlelo ze-MI sasiyimizuzu emi-2 nemizuzwana engama-24, uma kuqhathaniswa nemizuzu emi-4 nemizuzwana engama-55 yezinhlelo ze-SI, okubonisa ukwanda okukhulu kokusebenza kahle. Ukusetshenziswa kwansuku zonke kwe-Ama-injector e-CTfuthiAma-injector e-MRI, lokhu konga isikhathi kuvumela izikhungo zezithombe ukuthi zicubungule iziguli eziningi futhi zithuthukise ukusebenza kahle kwezokwelapha.

Ukunciphisa Ukulahleka Kokuqhathanisa kanye nokonga Izindleko

Imfucuza ye-contrast agent iyinto ebalulekile ezindleko zokusebenza kwesikhungo sokuthwebula izithombe. Ocwaningweni, izinhlelo ze-SI ezinesirinji ezingama-7.5ml zazinezinga lokuchitha elingu-13%, kanti izinhlelo ze-MI ezisebenzisa amabhodlela angama-7.5ml zanciphisa imfucuza yaba ngu-5%. Ngokusebenzisa amabhodlela amakhulu angama-15ml noma angama-30ml kanye nokwenza ngcono ukuhamba komsebenzi wokujova ngokwevolumu yesiguli, imfucuza yancishiswa kakhulu. Ezindaweni zokuskena ezinomthamo omkhulu, izinhlelo zokujova ezisetshenziswa kaningi zinganciphisa kakhulu izindleko ezisetshenziswayo, zinikeze izinzuzo zomnotho ezikhungweni zezempilo.

Ukwaneliseka Komqhubi Okuthuthukisiwe

Ulwazi lomqhubi luyisici esibalulekile ekukhetheni imishini yezokwelapha. Ucwaningo lwabasebenzi lubonise ukuthi izinhlelo ze-MI zithole amaphuzu aphezulu ekusebenzeni kahle kwesikhathi, ubungane bomsebenzisi, kanye nokulula kokusebenza, ngesilinganiso sokwaneliseka esimaphakathi esingu-4.7 kwabangu-5, uma kuqhathaniswa no-2.8 wezinhlelo ze-SI. Ulwazi oluthuthukisiwe lomqhubi alugcini nje ngokuthuthukisa ukwaneliseka emsebenzini kodwa futhi lunciphisa ingozi yamaphutha okusebenza, okuqinisekisa ukusetshenziswa okuphephile kweAma-injector e-CTfuthiAma-injector e-MRI.

Izinzuzo Zokuklama Zama-Injector Asetshenziswa Kaningi

Izinhlelo ze-MI zisebenzisa amakhatriji emithi yansuku zonke kanye namabhodlela okungafani angasetshenziswa kabusha, okudinga kuphela ukushintshwa kwamapayipi kanye nezesekeli ezilahlwayo zesiguli ngasinye. Uhlelo lungabamba izinhlobo ezimbili zama-ejenti okungafani ngasikhathi sinye, njenge-gadolinium ejwayelekile kanye ne-gadolinium eqondene nesibindi, okuhambisana nezidingo ezahlukene zokuskena. Lo mklamo unciphisa izinyathelo zokusebenza ngenkathi kugcinwa umthamo ohlukile wesiguli ngasinye. Zombili izinhlelo ze-MI kanye ne-SI ziqinisekiswe yi-CE, zihambisana nezindinganiso zokuphepha kwedivayisi yezokwelapha ye-EU ukuqinisekisa ukuphepha kwezokwelapha kanye nokuhlanzeka.

Ukubaluleka Kwezokwelapha Nezimboni

Ucwaningo lubonisa ukuthi ukusebenzisa ama-CT injector asetshenziswa kaningi kanye nama-MRI injector kunikeza izinzuzo eziphelele ekusebenzeni kahle, ukunciphisa izindleko, kanye nokwaneliseka kwabasebenzi. Ezikhungweni zezithombe, lokhu kusho ukugcina izithombe ezithuthukisiwe ngokuqhathaniswa kwekhwalithi ephezulu ezindaweni ezisebenza ngobuningi obukhulu ngenkathi kuthuthukiswa ukwabiwa kwezinsizakusebenza kwabasebenzi.

Ngaphezu kwalokho, njengoba izindleko ze-contrast agent zikhuphuka kanye nokugxila okwandayo ekusimeni kwemvelo, izinhlelo zokusebenzisa izinto eziningi zinikeza izinzuzo ezengeziwe. Ukunciphisa imfucuza akugcini nje ngokunciphisa izindleko kodwa futhi kusekela nemikhuba enobungani nemvelo ezikhungweni zezempilo zesimanje.

Izicelo Zesikhathi Esizayo

Njengoba ubuchwepheshe be-MRI kanye ne-CT buqhubeka nokukhula ekuxilongweni kwemitholampilo, izinhlelo zokujova ezisebenzayo neziphephile zizoba imishini ebalulekile yezikhungo zokuthwebula izithombe. Ucwaningo luhlinzeka ngedatha esekela ukusebenziseka kanye nenani lama-injector asetshenziswa kaningi emisebenzini yansuku zonke, lunikeza isiqondiso ezibhedlela ezinqumweni zokuthenga kanye nokwenza ngcono umsebenzi. Ama-injector e-CT asetshenziswa kaningi kanye nama-injector e-MRI cishe azoba yizilungiselelo ezijwayelekile esikhathini esizayo, athuthukise ikhwalithi yesevisi yokuthwebula izithombe iyonke.
