1.5T vs 3T MRI - chii chakasiyana?

Mazhinji maMRI scanner anoshandiswa mukurapa 1.5T kana 3T, aine 'T' inomiririra chikamu chesimba remagineti, inozivikanwa seTesla. MRI scanner ine Teslas yepamusoro inoratidzira magineti ane simba mukati memubobo wemuchina. Zvisinei, chikuru nguva dzose nani? Munyaya yeMRI magnetic simba, haisi nguva dzose.

Iyo yakakwira magineti simba MRI haingovimbisi kuongororwa kwakanyanya uye kuongororwa kwemamiriro ekurapa. Muchokwadi, iyo yakakwana yeMRI sarudzo inotsamira pane akasiyana zvinhu uye kufunga, senge mitezo chaiyo iri kufananidzwa, kuchengetedzwa kwemurwere uye nyaradzo, uye mhando yekufungidzira. Saka, ndepapi pakakodzera kushandisa 1.5T kana 3T scanner? Ngationgororei mimwe misiyano inokosha pakati pezviviri izvi.

Kuchengetedzeka uye Kumhanya Kwemifananidzo

Kuenzanisa scan speed uye kuchengetedza tembiricha yemuviri inopa dambudziko muMRI yakazara-muviri. Imwe yezvigadzirwa zveMRI iri kuwedzera tembiricha yemuviri, sezvo matishu emuviri anotora simba remagetsi panguva yekuongororwa, inozivikanwa seSpecific Absorption Rate (SAR). Paunenge uchitarisa nemuchina we1.5T, iwo miganho yekudziya inosvikwa pane dzimwe nzvimbo panguva yekuongororwa. Kana ma scans mamwe chete akaitwa ne 3T scanner, tembiricha yemuviri yaizokwira zvakapetwa kana, ichipfuura mwero wekupisa nekana. Pane nzira dzekugadzirisa nyaya iyi, sekuparadzanisa ma scans kuti awedzere nguva dze scan kana kuderedza kugadziriswa kwema scan. Nokudaro, kushandisa 1.5T MRI inosarudzwa sezvo inopa ruzivo rwakanyanya uye rwakachengeteka kune murwere pasina kukanganisa mufananidzo wemufananidzo.

Kuongorora Varwere Nemaimplants

Kunyanya kunetseka kune chero bvunzo yekufungidzira ndiyo nhanho yekuchengetedza, ndosaka bvunzo dzese dzekufungidzira dzine nhungamiro dzakasimba. Nezve MRI, kazhinji, varwere vanogona kuongororwa zvakachengeteka vachishandisa 1.5T uye 3T MRI michina.

Nekudaro, yakakwira magineti simba rinouya nenjodzi dzakakwirira. Varwere vane simbi inodyara uye michina, kusanganisira pacemakers, kunzwa AIDS, uye marudzi ose ekudyara, vanogona kukanganiswa nemagineti mu 3T scanners. Naizvozvo, varwere ava vangave vakachengeteka ne1.5T MRI scanner.

Imaging quality

Kurongeka kwemifananidzo yeMRI kwakakosha pakuongorora uye kuona kusagadzikana mukati memuviri. Zvinowanzofungidzirwa kuti MRI ine simba guru remagineti inobudisa mifananidzo yepamusoro. Kunyange zvazvo ichi chiri chechokwadi mune zvimwe zviitiko, 1.5T MRI muchina unosiyana-siyana wekufungidzira kwakawanda, nepo muchina we3T MRI unowanzo shandiswa kutora mifananidzo yakadzama yezvimiro zvidiki sehuropi kana wrist.

Hunhu hweMRI mifananidzo yakakosha pakuongorora kwakaringana uye kuona zvisirizvo. A 3T MRI scanner yakanyatsokodzera kufungidzira nzvimbo duku dzakadai seuropi uye majoini maduku. Zvisinei, simba remagineti rakakwirira rinogona kuva munondo unocheka kaviri.Imwe yakaderera ndeyokuti 3T MRI muchina unonyanya kubatwa nemifananidzo yakagadzirwa. Kuramba kusingabvumirwi kwe3T mumuzongoza uye muviri kunosanganisira kusununguka kubva kune gasi mumatumbo, iyo inogona kuvhara nhengo dzakapoteredza, pamwe chete nedielectric effect, apo nzvimbo dzechifananidzo dzinoita sedzakasviba nekuda kweredhiyo yewavelength inoshandiswa mumifananidzo ye3T. Panewo kuwedzera kwezvinhu zvinokonzerwa nemvura. Zvese izvi nyaya zvinogona kukanganisa kunaka kwe scan.

MuShoko

Kunyange zvazvo zvingaita sokuti yakakwirira-yakanyanya MRI scanner ndiyo yakanakisisa sarudzo, haisi iyo nyaya yose. Munyika yakakwana, radiologists vangada kuti MRI ibudise mifananidzo yepamusoro yevarwere vavo nekukurumidza uye zvakachengeteka. Zvisinei, chokwadi chinoratidza kuti haugoni kuva nayo usina kubvumirana pane zvisina kufanira. Saka, iwe uchawana nekukurumidza scans uchibhadhara yemhando yemufananidzo? Kana kusarudza scan yakachengeteka, asi njodzi yekufumura varwere kumuchina kwenguva yakareba? Mhinduro yakarurama inobva pakushandiswa kwekutanga kweMRI.

Imwe nyaya inofanirwa kutariswa ndeyekuti kana uchitarisa murwere, zvinofanirwa kubaya jekiseni rekusiyanisa mumuviri wemurwere.
