Njira Yodziwira Matenda a Ultrasonography

Ultrasound ndi ukadaulo wapamwamba wazachipatala, womwe wakhala njira yodziwira matenda yomwe imagwiritsidwa ntchito kwambiri ndi madokotala omwe ali ndi njira yabwino yowunikira. Ultrasound imagawidwa m'magulu awiri: njira ya mtundu wa A (oscilloscopic), njira ya mtundu wa B (imaging), njira ya mtundu wa M (echocardiography), njira ya fan (two-dimensional echocardiography), njira ya Doppler ultrasound ndi zina zotero. Ndipotu, njira ya mtundu wa B imagawidwa m'magulu atatu: line sweep, fan sweep ndi arc sweep, ndiko kuti, njira ya fan type iyenera kuphatikizidwa mu njira ya mtundu wa B.

Njira ya mtundu

Njira ya mtundu wa A imagwiritsidwa ntchito kwambiri pofufuza ngati pali zilonda zachilendo kuchokera ku kukula, kuchuluka kwa mafunde, ndi kutsatizana kwa mafunde pa oscilloscope. Ndi yodalirika kwambiri pozindikira matenda a hematoma ya ubongo, zotupa za muubongo, ma cysts, kutupa kwa m'mawere ndi m'mimba, mimba yoyambirira, hydatidiform mole ndi zina zotero.

Njira ya mtundu wa B

Njira ya mtundu wa B ndiyo yomwe imagwiritsidwa ntchito kwambiri ndipo imatha kupeza mitundu yosiyanasiyana ya ziwalo zamkati mwa munthu, popeza yakhala yothandiza kwambiri pozindikira ubongo, diso (monga retinal detachment) ndi orbit, thyroid, chiwindi (monga kuzindikira khansa ya chiwindi yaying'ono yosakwana 1.5 cm m'mimba mwake), ndulu ndi ndulu, kapamba, ndulu, obstetrics, matenda a akazi, urology (impso, chikhodzodzo, prostate, scrotum), kuzindikira zilonda zam'mimba, matenda a mitsempha yayikulu yamagazi mkati mwa m'mimba (monga m'mimba aortic aneurysms, inferior vena cava thrombosis), matenda a mitsempha yayikulu yamagazi pakhosi ndi miyendo. Zithunzi zake ndi zomveka bwino komanso zomveka bwino, zomwe zimapangitsa kuti zikhale zosavuta kuwona zilonda zazing'ono. Dziwani zambiri zamakina a ultrasound

Njira ya mtundu wa M

Njira ya mtundu wa M ndiyo kulemba mtunda wozungulira pakati pa echo ndi khoma la pachifuwa (probe) malinga ndi ntchito za mtima ndi ziwalo zina m'thupi. Ndipo kuchokera pa tchati ichi, khoma la mtima, septum yapakati pa ventricular, cavity ya mtima, valavu ndi zina zitha kuzindikirika bwino. Zolemba za ECG ndi mapu owonetsera mawu a mtima nthawi zambiri zimawonjezedwa nthawi imodzi kuti zizindikire matenda osiyanasiyana a mtima. Pa matenda ena, monga atrial myxoma, njira iyi ili ndi chiŵerengero chachikulu kwambiri chotsata malamulo.
