Ni izihe ntambwe ziherutse gutera imbere mu gushushanya amashusho mu buvuzi?

Kuva byatangira mu myaka ya 1960 kugeza mu myaka ya 1980, isuzuma rya Magnetic Resonance Imaging (MRI), isuzuma rya CT (computerized tomography), na positron emission tomography (PET) byateye imbere cyane. Ibi bikoresho byo gufata amashusho mu buvuzi bidakoresha imbaraga nyinshi byakomeje gutera imbere hamwe no guhuza ubwenge bw'ubukorano (AI), ubuhanga bwo gukusanya amakuru, n'isesengura ry'ibarurishamibare rya multi-parametric, byose bigira uruhare mu kunoza imyumvire no gusesengura sisitemu zacu z'imbere.

Iterambere mu gupima PET na CT

Gusuzuma PET bisanzwe bitwara hagati y'iminota 45 n'isaha imwe kugira ngo birangire kandi bishobora gutanga amashusho atandukanye y'imikurire y'ikibyimba mu bwonko, mu bihaha, mu nkondo y'umura, no mu tundi duce tw'umubiri. Iterambere rikomeje ryongereye imikorere y'ubu buryo, hashyirwaho porogaramu zo gukosora imiterere y'umubiri no gutuma isuzuma rya algorithm rishobora kumenya aho ikibyimba kiri mu ngingo zigenda.

Guhindagurika kw'ishusho bibaho iyo igice cy’icyerekezo kigenda mu gihe cyo gufata amashusho ya PET scan, bigatuma bigorana gusuzuma no gusesengura uburemere cyangwa ingingo. Kugira ngo bagabanye ingendo mu gihe cyo gupima PET scan, abahanga mu by'ubuzima bakoresha uburyo bwo kubona amakuru bushingiye ku mpande, bagagabanya uruziga rwo gupima mo "udusanduku" twinshi. Mu kugabanya inzira yo gupima mo udusanduku 8-10, porogaramu ishobora kumenya aho uburemere bw’ikintu runaka buzaba buri mu gihe runaka cyangwa ahantu runaka, hashingiwe ku byo umukoresha akunda. Ubu buhanuzi bukorwa mu guteganya aho uburemere buri mu dusanduku tw’icyerekezo. Uburyo bwo gufata amashusho ya PET gated bugabanya neza imihindagurikire y’ishusho iri mu gikoresho, bigatuma habaho kwiyongera kw’ibikorwa/agaciro gasanzwe ko kuvugurura (SUV). Iyo amakuru ya PET ahujwe n’amakuru ya CT, inzira yose izwi nka 4D CT scanning.

Nubwo bimeze gutyo, hari imbogamizi igaragara ijyanye n'ubu buryo. Gukoresha uburyo bwo gufata amashusho hifashishijwe amarembo bitera urusaku rwinshi bitewe no kubona amakuru menshi cyane. Ingamba nyinshi zo gukemura iki kibazo zirimo Q-freeze, Oncofreeze, n'igihe cyo kuguruka (ToF).

Uburyo ishusho idasobanutse neza ikosorwa muri PET na CT scans

Gukosora amashusho hakoreshejwe uburyo bwa Q-freeze, hakoreshejwe uburyo bwo kubona amashusho agenzuwe, bisaba gukusanya no kwandikisha amashusho yose yakozwe. Uku kwandika bibera mu mwanya w'ishusho, gukusanya no kongera gusana amakuru yose yakuwe muri PET scan kugira ngo hakorwe ishusho ya nyuma ifite urusaku ruke n'amarangamutima.

OncoFreeze, uburyo bwo gukora porogaramu ikora amashusho, ihuza na Q-freeze mu buryo bumwe na bumwe, nubwo bitandukanye muri rusange. Gukosora imikorere bikorwa mu mwanya wa sinogramu (umwanya w'amakuru asanzwe). Nyuma yo kubona ishusho ya mbere, amashusho akurikiraho adasobanutse agaragara imbere kandi agereranywa n'amakuru yatanzwe ku ntebe y'ubuganga n'ibipimo bya sinogramu bya backproject. Ibi bituma ishusho ivugururwa burundu ishingiye ku ishusho yo gukosora yasubiwemo.

Gufata imiyoboro y'ubuhumekero mu gihe cyo gupima PET hamwe na CT scans bishobora gutuma ishusho irushaho kuba nziza. Uburyo bwo kunoza imiterere y'imiyoboro y'ubuhumekero bushobora kugaragazwa no guhuza imiyoboro y'ubuhumekero ya PET scans, uburyo busanzwe, n'imiyoboro y'ubuhumekero ya CT scans, uburyo buherutse gukorwa.

Nkuko twese tubizi, iterambere ry’inganda zikora amashusho y’ubuvuzi ntaho ritandukaniye n’iterambere ry’ibikoresho bitandukanye by’ubuvuzi - injectors zikoresha ikoranabuhanga ritandukanye n’ibindi bikoresho bizifasha - bikoreshwa cyane muri uru rwego. Mu Bushinwa, buzwiho inganda zikora, hari inganda nyinshi zizwi cyane mu gihugu no mu mahanga mu gukora ibikoresho by’ubuvuzi, harimoLnkMedKuva yashingwa, LnkMed yibanda ku bijyanye n'injection zikoresha umuvuduko mwinshi. Itsinda ry'abahanga rya LnkMed riyobowe n'impamyabumenyi y'ikirenga (PhD) ifite uburambe bw'imyaka irenga icumi kandi ikora cyane mu bushakashatsi no mu iterambere. Iyobowe na we,Inshinge ya CT imwe mu mutwe, Inshinge ya CT ifite imitwe ibiri, Inshinge zo mu bwoko bwa MRI, naInshinge zikoresha umuvuduko mwinshi wa angiographybyakozwe hamwe n'ibi bintu: umubiri ukomeye kandi muto, uburyo bworoshye bwo gukora kandi bufite ubwenge, imikorere yuzuye, umutekano mwinshi, n'igishushanyo mbonera kirambye. Dushobora kandi gutanga seringe na tubes bihuye n'ibyo bicuruzwa bizwi cyane bya CT, MRI, DSA injectors Kubera imyumvire yabo ivuye ku mutima n'imbaraga zabo z'umwuga, abakozi bose ba LnkMed baragutumiye rwose kuza gusura andi masoko hamwe.
