I-Elastography

I-Elastography iyindlela esezingeni eliphezulu yokuxilonga esetshenziselwa ukuhlola ukuqina kwezicubu noma ukunwebeka, inikeza ulwazi olubalulekile mayelana nezimo ezihlukahlukene, ikakhulukazi lezo ezihilela isibindi, izinso, nemisipha. Ngokulinganisa ukuqina kwezicubu, i-elastography isiza odokotela ukuthi bahlole futhi baqaphe izifo, balandele ukuqhubeka kwezimo ezifana ne-liver fibrosis, futhi bahlole imiphumela yokwelashwa. Kuyithuluzi elibalulekile lodokotela abakhethekile abahlukahlukene, elinikeza enye indlela engahlaseli kuma-biopsies endabuko kanye nokwenza ngcono imiphumela yesiguli.

Iyini i-Elastography?

I-Elastography iyindlela yokwelapha yokuthwebula ekala ukuqina noma ukunwebeka kwezicubu emzimbeni. Isebenzisa amagagasi e-ultrasound noma imaging resonance kazibuthe (MRI) ukuze kutholwe izakhiwo zemishini zezicubu, ezingahluka ngenxa yezifo noma ukulimala. Ukuqina kwezicubu kungaba inkomba yezimo ezingaphansi, njenge-fibrosis (isibazi), ukuvuvukala, noma umdlavuza.

I-Elastography isetshenziswa ngokuyinhloko ukuhlola isibindi, izinso, imisipha, nezinye izicubu ezithambile. Ngokuvamile isetshenziswa njengethuluzi lokuxilonga ezimweni zesifo sesibindi esingamahlalakhona, ukuphazamiseka kwemisipha, kanye nomdlavuza othile. Ngokulinganisa ukuqina kwezicubu, i-elastography inikeza odokotela ulwazi olubalulekile ukuze benze ukuxilongwa okunembile futhi banqume izinhlelo ezifanele zokwelashwa.

Isebenza Kanjani I-Elastography?

I-elastography isebenza ngokulinganisa isivinini lapho igagasi lomshini (elikhiqizwa i-ultrasound noma i-MRI) lihamba ngesicubu esithile. Izicubu eziqinile zisakaza amagagasi ngesivinini esisheshayo kunezicubu ezithambile, ezinempilo. Lo mgomo usetshenziselwa ukubala ukunwebeka kwezicubu, ngemiphumela evame ukuboniswa njengamamephu anekhodi enombala noma amanani ezinombolo.

Kunezinhlobo ezimbili eziyinhloko ze-elastography:

• I-Shear Wave Elastography (SWE): Le ndlela isebenzisa i-ultrasound ukukhiqiza igagasi le-shear esicutshini. Ijubane elihamba ngalo igagasi liyalinganiswa, futhi ukuqina kwezicubu kuyanqunywa. Kuvame ukusetshenziselwa ukuhlola ukuqina kwesibindi ezigulini ezinesifo sesibindi.
• I-Transient Elastography (TE): Le nqubo isetshenziselwa ukukala ukuqina kwesibindi, ikakhulukazi ezigulini ezinezimo zesibindi ezingamahlalakhona njenge-cirrhosis noma i-hepatitis. I-TE ngokuvamile yenziwa kusetshenziswa idivayisi ebizwa ngokuthi i-FibroScan, ekhipha igagasi le-ultrasound ye-low-frequency ukuze ilinganise ukunwebeka kwesibindi.

Kuzo zombili lezi zindlela, ukumelana kwezicubu ekuguquguqukeni kulinganiswa, futhi imiphumela ivamise ukuvezwa ngama-kilopascals (kPa), iyunithi yokucindezela.

Ukusetshenziswa kwe-Elastography

I-Elastography inezinhlobonhlobo zokusetshenziswa, ikakhulukazi ekuhloleni izitho nezicubu ezingase zithintwe izifo. Ngezansi ezinye zezinhlelo zokusebenza ezibalulekile:
