Tsis tas li, txoj kev tshawb fawb no tau ua hauv cov txheej txheem inflammatory hauv sphenoid thiab ethmoid sinuses, vim lawv tsis tuaj yeem pom nrog x-rays. Cov lus qhia hauv qab no rau MRI yog qhov txawv:

  1. Nyob rau hauv neoplasm. Qhov no txhais tau tias tsis yog nyob rau hauv lub sinus kab noj hniav, tab sis kuj nyob rau hauv cov kab mob thiab cov ntaub so ntswg nyob ze.
  2. Kev ua pa nyuaj hauv qhov ntswg thaum tsis muaj x-ray hloov pauv.
  3. Kev mob ntawm lub qhov ntswg lossis lub ntsej muag pob txha taub hau.
  4. Anomalies nyob rau hauv cov qauv ntawm cov sinuses.
  5. Cyst nyob rau hauv nasopharyngeal kab noj hniav.
  6. mob taub hau uas tsis ploj mus ntev.
  7. Kev tsis txaus siab ntawm pansinusitis lossis o ntawm lub qhov txhab sab saud, pom cov ntshav hauv lawv cov kab noj hniav.

Nws tsim nyog nco ntsoov tias MRI yog suav tias yog cov ntaub ntawv tseem ceebtxoj kev. Yog li ntawd, yog tias ua tau, qhov kev ntsuam xyuas no yuav tsum tau muab qhov kev nyiam rau lwm qhov kev ntsuas ntawm cov sinuses.
