I-Bone Densitometry

Kuyaziwa ukuba izitolo ze-calcium emzimbeni ziqala ukuphela, ukususela kwiminyaka engama-30. Ngoko ke, kubalulekile ukuqalisa ukuxilongwa kwe- osteoporosis ngokukhawuleza, ngokunokwenzeka kubafazi. Kule njongo, inqubo entsha, i-densitometry yamathambo, iye yaphuhliswa. Le ndlela yokuphanda ikuvumela ukuba uqinisekise ngokukhawuleza nangokuchanekileyo ubuninzi beemamineral zeethambo zamathambo.

Uthini umahluko phakathi kwe-ultrasonic kunye ne-x-ray densitometry yamathambo?

Ezi zimbini iindidi zophando ezichazwe zisekelwe kwimiphumo eyahlukileyo.

Indlela yokuqala eboniswe ngayo ithatha ukusekwa kobuninzi beemaminerali ngoncedo lwe-densitometry yesithende kunye nesithambo somnatha. I-ultrasound oscillations ihamba ngokukhawuleza kwiisisisi kunokuba ilukhuni. Idatha efunyenweyo yenziwa yinkompyutha, iziphumo zinikezelwa ngendlela yee-indices ezibonisa ukuphambuka kwexilisi ye-calcium kwixabiso eliqhelekileyo. Le ndlela ithathwa njengechanekile ngokuchanekileyo, njengoko ivumela ukuxilonga i-osteoporosis kwisigaba sokuqala.

I-ray-ray i-densitometry yindlela yokucingwa kwe-lumbar ne-thoracic umgudu kwi-projection. Kule meko, ukuxinwa kwethambo kubalwa ngezixhobo ezizodwa ezisekelwe kwimifanekiso efunyenweyo.

Njengomthetho, indlela ye-ultrasound ifundisa ngokubanzi, kodwa emva kokuqhuba i-densitometry enjalo, uphando olupheleleyo lwe-radiographic luqeshwe ukuqinisekisa ukuxilongwa.

Ukulungiselela ithambo le-densitometry

Akukho mfuneko ekhethekileyo efunekayo phambi koviwo. Imfuno kuphela yinto yokuthatha amalungiselelo e-calcium iiyure ezingama-24 phambi kwe-densitometry.

Ukulungelelanisa, kuyafaneleka ezi ngcebiso ezilandelayo:

1. Gqoka izambatho eziphathekayo ezingenasiphelo ngaphandle kweensimbi zensimbi, ii-zippers kunye namaqhosha.
2. Susa ubunxibe kunye neiglasi.
3. Mcebisi ugqirha malunga nokukhulelwa okungenzeka.

Kubalulekile ukuba uqaphele ukuba akukho mfuneko yokulungiselela ukuxilongwa kwe-ultrasound, oku kuyinkqubo elula kakhulu kwaye ngokukhawuleza.

Ikhompyutriyitha yamathambo njani?

I-Monoblock i-ultrasound idivaysi ine-niche encinci apho unyawo, umunwe okanye isandla. Emva kwemizuzu eyi-15 (ngamanye amaxesha - ngaphantsi) kwemiphumo engenabuhlungu, iziphumo zokulinganisa zivela kwikhompyutha. Ukuxilongwa kusekwe ngokusekelwe kwezibonakaliso ezibini - T kunye noZ. Ixabiso lokuqala lihambelana nomlinganiselo (kwinqanaba) lokulinganiswa kwethambo lexabiso kunye nenani elifanayo kubantu abanempilo abangaphantsi kweminyaka engama-25. I-index-Z ibonisa ukuxilongwa kwe-calcium xa kuthelekiswa nomxholo oqhelekileyo wamaminerali kwiqela eliqhelekileyo lesigulane.

Uqikelelo olungaphezu kwe--1 ngongoma kubantu abaphilileyo. Iimilinganiselo ukusuka ku--1 ukuya ku--2.5 zibonisa ukuba khona kwe-osteopenia-isigaba sokuqala sokuthi umthambo uphelelwe ngamanzi. Ukuba amanqaku angaphantsi kwama--2.5, kunesizathu sokuseka ukuxilongwa kwe-osteoporosis.

I-X-ray i-densitometry yamathambo yenziwa njani?

Iimviwo zoviwo ezipakisha ziquka ietafile kunye nesithambiso esithambileyo apho umntu (elele phantsi) ukhona, kunye ne "sleeve" yeselula ehamba kunye nomzimba kwaye isigulane. Ukongezelela, kukho i-brace, apho imilenze ifakwa khona xa uthatha umfanekiso womxube we-hip.

I-generator ye-X yenziwe kwitheyibhile, kwaye isicatshulwa sokupakisha imifanekiso yesigcawu imifanekiso ifakwa kwisandla. Emva kwe-densitometry, ziboniswa kwikhompyutha.

Ngethuba le nkqubo, kubalulekile ukulala ngaphandle kokuhamba, ngezinye iingcali zicela ukuba zibambe ukuphefumula kwithuba elincinci ukuphepha ukutshatyalaliswa komfanekiso.

Iziphumo zichazwe ngu-radiologist, ebonisa amanqaku aqikelelweyo okuxinwa kwe-calcium emathanjeni nakubunzima bomzimba.
