Okufanele balinganise ukuminyana kwamathambo ngokusebenzisa i-bone densitometer
I-Bone Densitometry
I-osteoporosis ukulahlekelwa okukhulu kwamaminerali amathambo okuthinta izigidi zabesifazane, okubabeka engcupheni yokuphuka okungase kube buthakathaka.Sinikeza i-bone densitometry, ekala ngokunembile ukuminyana kwamaminerali (BMD), okuvumela ukulinganiswa kwengozi yokuphuka kwesiguli.Isistimu yethu ethuthukisiwe iyakwazi ukubala ngokunembile i-BMD emgogodleni, okhalweni, noma esihlakaleni.Uhlelo futhi luvumela ukunqunywa kwe-BMD kubantu bezingane.
Udokotela wakho angase alawule i-bone densitometry uma esola ukuthi unayo noma usengozini yokuthuthukisa i-osteoporosis.Abantu abane-osteoporosis banamathambo abuthakathaka noma ukulahlekelwa okukhulu kwamathambo abo amaminerali.Izigidi zabesifazane namadoda amaningi baba ne-osteoporosis njengoba bekhula.
Isebenza kanjani i-Bone Densitometry
Kwesinye isikhathi lokhu kuhlolwa kubizwa nge-bone density scanning noma i-dual-energy x-ray absorptiometry (DXA).Kuwuhlobo oluthuthukisiwe lobuchwepheshe be-x-ray.Umshini we-DXA uthumela ugongolo oluncane, olungabonakali lwe-x-ray yedosi ephansi ngokusebenzisa amathambo.Izicubu zakho ezithambile zimunca umsebe wamandla wokuqala.Amathambo akho amunca ugongolo lwesibili.Ngokukhipha inani lezicubu ezithambile esiphelele, umshini uhlinzeka ngesilinganiso sokuminyana kwamaminerali ethambo lakho (BMD).Lokho kuminyene kutshela udokotela amandla amathambo akho.
Kungani Odokotela Basebenzisa I-Bone Densitometry
I-osteoporosis ihilela ukulahlekelwa kwe-calcium emathanjeni akho.Kuyisimo esivame ukubathinta abesifazane ngemuva kokunqamuka kokuya esikhathini, nakuba amadoda angaba ne-osteoporosis, nawo.Kanye nokulahlekelwa kwe-calcium, amathambo adlula ezinguqukweni zesakhiwo ezibangela ukuba abe mancane, abe ntekenteke futhi aphuke.
I-DXA iphinde isize odokotela be-radioologists nabanye odokotela ukulandelela ukusebenza kokwelashwa kwanoma yiluphi uhlobo lwesimo sokulahleka kwamathambo.Izilinganiso zokuhlolwa zinikeza ubufakazi ngengozi yakho yokuphuka ithambo.
Ubani Okufanele Athole Ukuhlolwa Kwe-Bone Mineral Density (BMD).
• Abesifazane abaneminyaka engama-65 nangaphezulu
• Abesifazane abangemva kokuya esikhathini abangaphansi kweminyaka engama-65 abanezici eziyingozi zokuphuka.
• Abesifazane ngesikhathi senguquko yokuya esikhathini abanezici eziyingozi zomtholampilo zokuphuka, njengesisindo somzimba esiphansi, ukuphuka kwangaphambili, noma ukusetshenziswa kwemithi eyingozi kakhulu.
• Amadoda aneminyaka engama-70 nangaphezulu.
• Amadoda angaphansi kweminyaka engama-70 anezici zobungozi zomtholampilo zokuphuka.
• Abantu abadala abanokukhubazeka okubuthakathaka.
• Abantu abadala abanesifo noma isimo esihambisana nokuncipha kwamathambo noma ukulahlekelwa amathambo.

• Noma ubani ocatshangelwa ukwelashwa kwe-pharmacologic (izidakamizwa).
• Noma ubani owelaphayo, ukuqapha umphumela wokwelashwa.
• Noma ubani ongatholi ukwelashwa lapho ubufakazi bokulahlekelwa amathambo buyoholela ekwelashweni.
• Abesifazane abayeka ukusebenzisa i-estrogen kufanele bacatshangelwe ukuhlolwa kokuqina kwamathambo ngokwezinkomba ezibalwe ngenhla.
Kungani Odokotela Basebenzisa Ukuhlola Ukuphuka Kwama-Vertebral (VFA)
Okunye ukuhlolwa okwenziwa emshinini we-DXA ukuhlola ukuphuka kwe-vertebral fracture (VFA).Ukuhlolwa kwe-x-ray enedosi ephansi yomgogodla okuhlola impilo yomgogodla wakho.I-VFA izodalula ukuthi unawo yini ama-compression fractures ku-vertebra yakho (amathambo asemgogodleni wakho).Ukuba khona kwe-vertebral fracture kubaluleke nakakhulu ekubikezeleni ingozi yokuphuka kwamathambo esikhathini esizayo kune-DXA kuphela.Lokhu okulandelayo yizizathu (izinkomba) zokwenza ukuhlolwa kwe-vertebral fracture (VFA) ngokusekelwe Ezikhundleni Ezisemthethweni ze-2007 ze-International Society of Clinical Densitometry (www.iscd.org):
Ubani Okufanele Athole I-VFA
• Abesifazane basePostmenopausal abane-low bone mass (i-osteopenia) ngokwemibandela ye-BMD, KANYE nanoma yikuphi kokulandelayo:
• Ubudala obungaphezu noma obulingana neminyaka engama-70
• Ukulahleka kobude okungokomlando okukhulu kuno-4 cm (1.6 in.)
• Ukulahleka kobude okulindelwe kungaphezu kuka-2 cm (0.8 in.)

• Iminyaka yobudala engama-70 kuye kwengama-79
• Ukuphuka okungeyona i-vertebral okuzibike ngaphambili
• Ukulahleka kobude obungokomlando obungu-3 kuya ku-6 cm
• Ekwelashweni kokuncishwa kwe-androgen kwe-pharmacologic noma ukulandela i-orchiectomy
• Izifo zesistimu ezingalapheki ezihlotshaniswa nengozi eyengeziwe yokuphuka komgogodla (isibonelo, i-COPD emaphakathi noma eqinile noma i-COAD, i-seropositive rheumatoid arthritis, isifo sika-Crohn)
• Abesifazane noma amadoda athola ukwelashwa okungapheli kwe-glucocorticoid (okulingana no-5 mg noma ngaphezulu we-prednisone nsuku zonke izinyanga ezintathu (3) noma ngaphezulu).
• Abesifazane be-Postmenopausal noma amadoda ane-osteoporosis nge-BMD criteria, uma imibhalo ye-vertebral fracture eyodwa noma ngaphezulu izoshintsha ukuphathwa komtholampilo.
Ukulungiselela ukuhlolwa kwakho kwe-Bone Densitometry
Ngosuku lwakho lwesivivinyo, yidla ngokujwayelekile kodwa sicela ungathathi izithasiselo ze-calcium okungenani amahora angama-24 ngaphambi kokuhlolwa kwakho.Gqoka izingubo ezikhululekile, ezikhululekile futhi ugweme izingubo ezinoziphu wensimbi, amabhande noma izinkinobho.I-Radiology & Imaging ingase ikucele ukuthi ukhiphe ezinye noma zonke izingubo zakho futhi ugqoke ingubo noma ingubo ngesikhathi sokuhlolwa.Kungase kudingeke futhi ukhiphe ubucwebe, izibuko zamehlo nanoma yiziphi izinto zensimbi noma izingubo zokugqoka.Izinto ezinjengalezi zingaphazamisa izithombe ze-x-ray.
Yazisa udokotela wakho uma usanda kuhlolwa i-barium noma ujovwe ngento ehlukile kuskena se-computed tomography (CT) noma i-radioisotope (imithi yenuzi).
Ngaso sonke isikhathi yazisa udokotela wakho noma i-Radiology & Imaging technologist uma kukhona okungenzeka ukuthi ukhulelwe.
Yini Isivivinyo Se-Bone Densitometry
Thanda
Ulala phezu kwetafula elinephedi.Ukuze kuhlolwe i-Central DXA, ekala ukuminyana kwamathambo enqulwini nasemgogodleni, ijeneretha ye-x-ray ingaphansi kwakho futhi idivayisi yokuthwebula, noma umtshina, ungaphezulu.Ukuze uhlole umgogodla wakho, imilenze yakho isekelwa ebhokisini elicijile ukuze ululaze i-pelvis yakho kanye nomgogodla ophansi (i-lumbar).Ukuze uhlole i-hip, uchwepheshe wezobuchwepheshe uzofaka unyawo lwakho ku-brace ezungeza inqulu yakho ngaphakathi.Kuzo zombili izimo, umtshina udlula kancane kancane, ukhiqize izithombe kusiqapha sekhompyutha.Izivivinyo eziningi zithatha imizuzu eyi-10-20 kuphela futhi kubalulekile ukuthi unganyakazi phakathi nokuhlolwa.
Izinzuzo Nezingozi
I-Bone densitometry ilula, iyashesha futhi ayivaleli.Ayidingi i-anesthesia.Inani lemisebe elisetshenzisiwe lincane kakhulu—lincane kakhulu kunomthamo we-x-ray yesifuba esivamile.
Nganoma iyiphi inqubo ye-x-ray, kunethuba elincane lomdlavuza kusukela ekuchayekeni ngokweqile emisebeni.Nokho, inzuzo yokuxilongwa okunembile idlula kude ingozi.Abesifazane kufanele ngaso sonke isikhathi bazise udokotela wabo noma i-Radiology & Imaging technologist uma kukhona okungenzeka ukuthi bakhulelwe.
Imikhawulo ye-Bone Densitometry
I-Densitometry yamathambo ayikwazi ukubikezela ngokuqiniseka okungu-100% uma uzophuka ngokuzayo.Kodwa-ke, inganikeza izinkomba eziqinile zengozi yakho yokuphuka esikhathini esizayo.
Naphezu kokuphumelela kwayo ekulinganiseni amandla amathambo, i-bone densitometry noma i-DXA isetshenziswa okulinganiselwe kubantu abanokukhubazeka komgogodla noma kubantu abaye bahlinzwa umgogodla.Uma une-vertebral compression fractures noma i-osteoarthritis, isimo sakho singase siphazamise ukunemba kokuhlolwa.Kulezi zimo, kungenziwa okunye ukuhlolwa, njenge-forearm bone densitometry.
We Subspecialise In Reading Bone Images
I-Radiology & Imaging isebenzisa okokusebenza kwesimanje okuhlinzeka ngemininingwane ehlukile yokuxilonga.Izazi ze-radiologist zethu zokucabanga ngomzimba noma izazi ze-musculoskeletal radiologists zisebenza ngokukhethekile ekufundeni i-bone densitometries okusho ukuthi ubungcweti obuningi nolwazi lusebenzela wena.
