I-Bone Densitometry

Kuyaziwa ukuthi izitolo ze-calcium emzimbeni ziqala ukuphela, kusukela ekuqaleni kweminyaka engama-30. Ngakho-ke, kubalulekile ukuqala ukuhlolisisa ukukhubazeka ngokweqile ngangokunokwenzeka, ikakhulukazi kwabesifazane. Ngenxa yalezi zinhloso, inqubo entsha, i-densitometry yamathambo, iye yasungulwa. Le ndlela yokucwaninga ikuvumela ukuba unqume ngokushesha futhi ngokunembile ukulinganisa kwamaminerali amathambo amathambo.

Uyini umehluko phakathi kwe-ultrasonic ne-x-ray densitometry yamathambo?

Izinhlobo ezimbili zokuhlola ezichazwe zisekelwe emiphumeleni ehluke kakhulu.

Indlela yokuqala ekhonjisiwe iqala ukusungulwa kwamaminerali amaningi ngosizo lwe-densitometry yesithende ne-bone radius. Ukuchithwa kwe-Ultrasound kuyashesha kakhulu kumathisiphi kunokuba kunzima kakhulu. Idatha etholakala ngaleyo ndlela iqhutshwa yikhomputha, imiphumela inikezwa ngendlela yama-indices ebonisa ukwehlukana kokuhlushwa kwe-calcium ezilinganisweni ezivamile. Le ndlela ibhekwa njengenembile kakhulu, njengoba ivumela ukuxilonga i-osteoporosis ngesikhathi sokuqala.

I-ray-ray densitometry yi-imaging ye-lumbar ne-thoracic umgogodla ekuhloleni kwe-lateral. Kulesi simo, isibalo samathambo sibalwa ngokusebenzisa imishini ekhethekile esekelwe ezithombeni ezitholakalayo.

Njengomthetho, indlela ye-ultrasound ifundisa kabanzi, kodwa ngemva kokwenza i-densitometry enjalo, ukutadisha okuphelele kwe-radiographic kuqokwe ukuze kuqinisekiswe ukuxilongwa.

Ukulungiselela i-densitometry yethambo

Akukho ukulungiselela okhethekile okudingekayo ngaphambi kokuhlolwa. Imfuno kuphela akumele ithathe amalungiselelo e-calcium amahora angu-24 ngaphambi kwe-densitometry.

Ukuze kube lula, kufanelekile izincomo ezilandelayo:

1. Gqoka izingubo ezizimele ezingenalutho ngaphandle kwezinsimbi zensimbi, zipper kanye nezinkinobho.
2. Susa ubucwebe nezibuko.
3. Qaphela udokotela mayelana nokukhulelwa okungenzeka.

Kufanele kuqaphele ukuthi asikho isidingo sokulungiselela ukuxilongwa kwe-ultrasound, lokhu kuyindlela elula futhi elula.

I-densitometry yamathambo kanjani?

Amadivayisi we-Monoblock ultrasound ane-niche encane lapho unyawo, umunwe noma isandla kufakwa khona. Ngemva kwamaminithi angu-15 (ngezinye izikhathi - ngaphansi) imiphumela engenamiphumela, imiphumela yokulinganisa ivela kukhompyutha. Ukuxilongwa kusungulwa ngesisekelo sezinkomba ezimbili ezibalulekile - T noZ. Inani lokuqala lihambisana nobubanzi (kumaphoyinti) obuningi bamathambo alinganiselwe ngenani elifanayo kubantu abanempilo abangaphansi kweminyaka engu-25. I-Z-indebe ibonisa ukuxilongwa kwe-calcium uma kuqhathaniswa nokuqukethwe okujwayelekile kwamaminerali eqenjini elidala lesiguli.

Kulinganiselwa ngaphezu kwezingu--1 iphuzu lezici zabantu abaphilile. Amanani kusukela ku--1 kuya ku--2.5 akhombisa ukutholakala kwe-osteopenia - isigaba sokuqala se-demineralization yamathambo. Uma le score ingezansi -2.5 amaphuzu, kunesizathu sokuthola ukuxilongwa nge-osteoporosis.

I-X-ray i-densitometry yamathambo isenziwa kanjani?

Izinhlelo zokuhlola zokugcina zihlanganisa itafula elinesibopho esithambile lapho umuntu (elele phansi) etholakala khona, kanye "nomkhono" weselula ohamba emzimbeni futhi ohlala endaweni isiguli. Ngaphezu kwalokho, kukhona i-brace, lapho imilenze ifakwa khona lapho uthatha isithombe sohlangothini lwe-hip.

I-generator X-ray yakhiwe etafuleni, futhi idivaysi yokucubungula isithombe sedijithali yezithombe ifakwa emanzini. Emva kwe-densitometry, iboniswa kwesikrini sekhompyutheni.

Phakathi nenqubo, kubalulekile ukulala ngaphandle kokuhamba, ngezinye izikhathi ochwepheshe bacela ukubamba umoya okwesikhashana ukuze ugweme ukufiphaza isithombe.

Imiphumela ichazwa yi-radiologist, ebonisa ukuthi ukuhlushwa kwe-calcium okulinganiselwe emathanjeni nasezintweni zomzimba.
