Kusiyana nezvinotaurwa nezita rayo, the fibroscan haisi fiberoptic, kana scanner. Uyu muedzo unosanganisira quantifying the chiropa fibrosis, nekuona kuoma kwe chiropa tishu. Zvakanakira ndezvekuti haufanirwe kupinda mukati memuviri: iyo fibroscan inorwadza uye isina-invasive bvunzo. Iyo fibroscan (iro iro chairo zita re tekinoroji ine patent nekambani yeFrance, Echosens) inonzi zvakare ultrasonic impulse elastometry.

Chiropa fibrosis mhedzisiro yekuwanda zvinetso zvechiropa zvisingaperi : chidhakwa, hutachiona hepatitis, etc. Izvi zvinotungamirira pakuumbwa kwevanga renyama rinotsiva masero echiropa akakuvadzwa: iyi inonzi fibrosis. Iyo inovhiringidza magadzirirwo echiropa zvese anatomically uye nekushanda, uye kufambira mberi kwayo kunogona kutungamira kune cirrhosis (mavanga enyama aripo muchiropa chose).

Chiremba anoita fibroscan kuti aone kuoma kwechiropa fibrosis. Ongororo iyi zvakare inoita kuti zvikwanise kutarisa mafambiro ayo.

Iyi bvunzo inogona zvakare kushandiswa kune:

• kuongorora hepatitis pasi pekurapwa
• tarisa matambudziko e cirrhosis
• kuongorora matambudziko mushure chiropa chekuisa
• kuratidza mamota echiropa

Ziva kuti kuongororwa kwehepatic fibrosis kunogona kuitwa zvakare chiropa biopsy (kutora masero echiropa) kana nekuongorora ropa, asi bvunzo idzi dzinopinda, kusiyana nefibroscan.

Iyo nzira haina kurwadza uye inofananidzwa neiyo ultrasound.  

Iyo fibroscan inosanganisira kushandisa iyoelastometry (or elastography) impulse controlled vibration: nzira inoshandiswa kuongorora kupararira kweshock wave muchiropa uye kuyera kusimba kwayo. Iyo inokurumidza kukurumidza kupararira, chiropa chinowedzera kusimba, uye naizvozvo fibrosis yakakura.

Kuti aite izvi, chiremba anoisa probe pakati pembabvu pamusoro peganda remurwere akarara nemusana ruoko rwerudyi rwakaiswa kuseri kwemusoro. Iyo probe inogadzira yakaderera frequency wave (50 Hz) iyo inopfuura nepachiropa uye inotumira wave kumashure kune probe. Chishandiso chinoverenga kukurumidza uye simba reiyi echo kuongorora kusimba kwechiropa.

Zviyero zvinenge gumi zvakakodzera zvinofanira kutorwa panguva yekuongorora.

Bvunzo rinongotora maminetsi mashanu kusvika gumi nemashanu uye mhedzisiro yacho ipapo ipapo.

Iyo elasticity yechiropa inoyerwa mu kilopascal (kPa). Kukosha kwakawanikwa kunopindirana nepakati pezviyero zve 10 uye nhamba inotenderera pakati pe2,5 ne75 kPa.

Saka, zvichienderana nekukuvadzwa kwechiropa, zvibodzwa zve elasticity zvinosiyana, fibrosis inowedzera kana kushoma uye matanho akasiyana anotsanangurwa:

• pakati pe2,5 ne7, tinotaura nezvedanho F0 kana F1: kusavapo kwefibrosis kana diki fibrosis.

• pakati pe7 ne9,5, tinotaura nezvedanho F2: moderate fibrosis

• pakati pe9,5 ne14, tinotaura nezvedanho F3: fibrosis yakaoma

• Kupfuura gumi nemana, tinotaura nezvedanho F14: mavanga mavanga aripo pachiropa, uye cirrhosis iripo.

Kuti apedze kuongororwa kwake, chiremba anogona kuraira dzimwe ongororo dzakadai se chiropa biopsy kana kuongorora ropa.
