Dzimwe nguva mu-ultrasound-kuwanikwa muvharari-kuruboshwe kana kurudyi chiremba anonyora nezvekuvapo kweanechogenous formations. Echogenicity ndiro izwi rinoshandiswa mu ultrasound diagnostics kuratidza kuti kutenderera kwemafungu emashonga nemaviri. Maitiro akadai semapfupa anonyatsoratidza ultrasound nekuda kwehupamhi hwayo, uye inonyatsoratidzwa pamuganhu wezviviri uye masukisi ane mweya. Micheka yakawanda inoratidza ultrasound zvakasimba kwazvo, uye iyo ine zvakawanda zvekuita kwemvura chiratidzo che ultrasonic sensor, ichichisimbisa panguva imwechete.
Izwi re ultrasound uye dense tissues (bone) inoratidzwa kubva kubva muzviviri uye mishonga inoratidzwa pahwindo rekuona, uye mhepo inotarisa yakachena (hyperechoic), chiratidzo hachipfuuri shure kwavo, uye shure kwavo pane bhandi dema rakaenzana nechiratidzo chinoratidzwa (acoustic shadow). Iyo inowedzera dense weave, inowedzera echogenicity (iyo yergter inotarisa), iyo inowedzera mvura ine mhuka kana nhengo (kusanganisira midzi yeropa neropa) - yakaderera maitiro echogenicity, uye mafomu emvura achave anechogenous (madema).
Maitiro ehuvha pa ultrasound
Kazhinji kune anechoic cavity yemasikirwo akasiyana mukati memukati. Kuti unzwisise kuti chidimbu chinowanzoitwa neyvaline uye anechoic ovarian cyst inoratidzika sei pane ultrasound, iwe unofanirwa kuziva kuti chii chinoshanduka pakuitika kwemazuva ose. Pashure pemagumo ekuenda kumwedzi, follicles inotanga kukura mune rimwe kana mavari mavari: madiki anehogenous kuiswa kwechimiro chevirumusi muvhavhari uye chiyero chema 1-3 mm chinokura kusvika 7-8 mm, izvi zvinowanikwa muhafu yekutanga yemhepo. Zvadaro, kubva kune follicles inokunda - inoenderera mberi kukura muhukuru kubva 16-17 kusvika 25-30 mm, kubva pairi panguva yekuvhunga mazai evha.
Mushure mokunge kusunungurwa kweivule, denderedzwa yakagadzirwa zvishoma nezvishoma inopera muhukuru, inova isina kumira muhumwe, ichichinja kuva muviri wechizha. 2-3 mazuva asati atanga kuenda kumwedzi, iyo yomuviri inomira kushanda uye kazhinji inoputika, kusunungura kaduku kadiki, naizvozvo, kubvira pakutanga uye kusvikira pakupera kwechiso mumapapiro maawa haafaniri kuva neochogenic maitiro.
Kana mimba ikaitika, iyo yomuviri yemajena inoshandisa chekutanga chetatu yekuita pamuviri uye inoratidzika se anechogenous form of a circular shape pane imwe yamavhapiti (yellow body of pregnancy inobereka progesterone).
Ovarian cysts pa ultrasound
Kusiyana kwakasiyana-siyana kwemashure ehomoni mumukadzi uye basa revhavha rake rinogona kutungamirira kune maitiro eimwe anechogenous formations - ovarian cysts.
- Kazhinji kazhinji pane imwe mazai, chest follicular inowanika - anechogenous maitiro ehuwandu hwomukati, wehutano hwakasiyana nehutapukisi hutete, hunoyera kubva pa3 kusvika ku6 masendimita. Izvo zvinoitika nehutachiona hwehutachiona hunoita kuti kusavapo kweivulation - mazai haasi kusiya follicle, iyo inoramba ichikura mukukura. Zvinyorwa zvinyorwa zvinonyangarika panguva ya1 kusvika kumwedzi, nguva shoma, dzakaoma, dzinoda kurapa kwakakodzera.
- Kazhinji pane mavha mavari imwe anechogenous formation inowanika - inonzi endometrioid cyst . Chimwe chinhu chakasiyana chekugadzirwa uku ndechimwe chakaoma,
heterogeneity ye cyst uye yakakura nguva dzose kana kukura pamusoro pemakore akawanda ekuenda kumwedzi. Ukuru hwekupedzisira kwekristi inogona kuva yakasiyana-kubva pamamilimita mashoma kusvika kune masendimita akawanda, cysts ine endometriosis isina uye yakawanda. - Mamwe anehogennye maitiro - asina kuroorwa kana mashoma-chambered serous cysts, haagoni kungova sangano rakasununguka, asiwo kuratidzwa kweumwe, somuenzaniso, chirwere chakaipa. Multichamber, heterogeneous echopositive inclusions kana kupararira pamadziro mukati mezvivakwa zvakadai zvinogona kuratidza kuipa kunoratidzira mukati mavarivha.
