Zvinonyatsozivikanwa kuti zvivigiro zve calcium mumuviri zvinotanga kupera, kubva pazera remakore makumi matatu. Saka, zvakakosha kutanga kuongorora hutachiona hwehutano sezvichibvira , kunyanya kuvakadzi. Nokuda kwezvinangwa izvi, nzira itsva, densitometry yemapfupa, yakagadzirwa. Iyi nzira yekutsvakurudza inokubvumira kuti iwe nokukurumidza uye zvakarurama uone huwandu hwemaminera emapfupa.
Ndechipi musiyano pakati pea ultrasonic uye x-ray densitometry yemapfupa?
Mhando mbiri dzeongororo dzinotsanangurwa dzinobva pamigumisiro yakasiyana zvakasiyana.
Nzira yekutanga inoratidzirwa inotanga kuumbwa kwemaminerari akawanda pamwe nekubetsera densitometry chechitsinho uye radius bone. Ultrasound oscillations inokurumidza muhutu kupfuura iyo inopisa. Iyo data yakagadziriswa inoshandiswa nekombiyuta, zvigumisiro zvinopiwa nenzira yehutsananguro dzinoratidza kukanganisa kwema calcium kutarisa kubva kune zvakakosha. Iyi nzira inofungidzirwa yakarurama kwazvo, sezvo inobvumira kufungidzira osteoporosis panguva yekutanga.
X-rays densitometry inofanirwa kugadzirwa kwekambar uye thoracic spine mumushure wekupedzisira. Muchiitiko ichi, kuwedzera kwepfupa kunoratidzwa nenzira yezvigadzirwa zvakasiyana zvinoenderana nemifananidzo yakawanikwa.
Sezvo mutemo, nzira ye ultrasound inonyanya kudzidzisa, asi mushure mokuita densitometry yakadaro, kuongorora kwakazara radiographic kunosarudzwa kuti kusimbise kuongororwa.
Kugadzirira fupa densitometry
Hapana gadziriro yakakosha inodiwa mushure mekuongorora. Chinodiwa chete hachisi kutora calcium kugadzirira maawa makumi maviri nemaviri asati apera.
Kuti zvive nyore, zvakakosha zvinotevera mazano:
- Kupfekedza zvipfeko zvisina kusimba zvisingashandisi midziyo yesimbi, zippers uye mabhatani.
- Bvisa zvishongo uye magirazi.
- Cherechedza chiremba nezvekugona kutakura pamuviri.
Zvakakosha kuziva kuti hapana chikonzero chekugadzirisa ultrasound diagnostics, ichi chinhu chakajeka uye chinokurumidza.
Ko kombiyuta yakaita sei mamapfupa?
Monoblock ultrasound madivayiri ane niche duku umo tsoka, munwe kana ruoko inowanikwa. Pashure pemaminitsi gumi nemashanu (dzimwe nguva - zvishoma) migumisiro isingarwadzi, migumisiro yezviyero inobuda kune kombiyuta. Kuongororwa kunosimbiswa pachishandiswa zviratidzo zviviri zvakakosha - T uye Z. Kukosha kwekutanga kunofananidzwa nechiyero (muzvikamu) chekuyera kwemafupa emasero ane kukosha kwakafanana kune vanhu vane utano hwakanaka pasi pemakore makumi maviri nemashanu. I-Z-index inoratidza huwandu hwekasiki yakaenzaniswa nehuwandu hwemigodhi inogadziriswa muboka rinotarisana nemurwere.
Inofanirwa kupfuura kupfuura -1 pfungwa ndeyevanhu vane utano. Maitiro kubva kubva ku1 kusvika ku2.5 anoratidza kuvepo kweasteopenia - danho rekutanga rekudzikisa mapfupa. Kana chikamu ichi chiri pasi pemakumi maviri -5, pane chikonzero chekugadzirisa kuongororwa kweasteoporosis.
Ko X-ray densitometry yemapfupa inoitwa sei?
Imwe nyanzvi yekuongororwa inosanganisira tafura ine chifukidzo chakareruka apo munhu (akarara pasi) aripo, pamwe ne "sleeve" inofamba inofamba pamuviri uye inogara panzvimbo
A X-ray generator inovakwa mutafura, uye chidimbu chekugadzira chifananidzo chemajeri chezvifananidzo chinowanikwa mujasi. Mushure mokunge densitometry, inoratidzwa pamakombiyuta.
Panguva yekufamba, zvakakosha kurara pasi usina kufamba, dzimwe nguva nyanzvi dzinokumbira kubata kufema kwako kwenguva pfupi kuti urege kusvibisa mufananidzo.
Zvigumisiro zvinotsanangurwa nehu radiologist, zvichiratidza kuti yakawanda yakawanda yeakisiyamisi yakakanganiswa mumapfupa uye masimba.
