Virtual colonoscopy

Virtual colonoscopy (VC) imaging kana x-ray bvunzo inotarisa kenza, polyps, kana chimwe chirwere mumatumbo makuru (colon). Zita rekurapa remuyedzo uyu CT colonography.

VC yakasiyana neyakajairwa colonoscopy. Nguva dzose colonoscopy inoshandisa chishandiso chakareba, chakavhenekerwa chinonzi colonoscope iyo inoiswa mukati mehuturu uye hutumbu hukuru.

VC inoitwa mudhipatimendi re radiology rechipatara kana nzvimbo yekurapa. Hapana sedatives anodiwa uye hapana colonoscope inoshandiswa.

Bvunzo dzinoitwa seinotevera:

• Unorara kuruboshwe kwako patafura yakamanikana yakabatana neMRI kana CT muchina.
• Mabvi ako akaswededzwa kuchipfuva chako.
• Iyo diki, inochinja chubhu inoiswa mukati meye rectum. Mhepo inoputirwa nepombi kuita kuti colon iwedzere uye ive nyore kuona.
• Iwe chibva warara nemusana.
• Tafura yacho inotsvedza kupinda mumugero muhombe muCT kana MRI muchina. X-ray yekoloni yako inotorwa.
• X-ray inotorwawo paunenge wakarara nedumbu.
• Iwe unofanirwa kugara wakanyarara panguva iyi maitiro, nekuti kufamba kunogona kukanganisa x-ray. Iwe unogona kukumbirwa kubata mweya wako muchidimbu apo imwe x-ray inotorwa.

Komputa inosanganisa mifananidzo yese kuti iumbe matatu-mativi emifananidzo yekoloni. Chiremba anogona kuona iyo mifananidzo pane vhidhiyo yekutarisa.

Hura hwako hunofanira kunge husina chinhu uye hwakachena bvunzo. Dambudziko mumatumbo ako makuru rinoda kurapwa rinogona kushaikwa kana ura hwako husina kucheneswa.

Anokuchengetedza hutano anokupa matanho ekuchenesa ura hwako. Izvi zvinonzi kugadzirira ura. Matanho anogona kusanganisira:

• Uchishandisa enemas
• Kusadya kudya kwakasimba kwemazuva 1 kusvika matatu muedzo usati waitwa
• Kutora laxatives

Unofanirwa kunwa zvinwiwa zvakawanda zvakajeka kwemazuva 1 kusvika ku3 usati waedzwa. Mienzaniso yezvinwiwa zvakajeka ndeiyi:

• Bvisa kofi kana tii
• Bouillon isina mafuta kana muto
• Gelatin
• Zvinwiwa zvemitambo
• Yakaomeswa michero majusi
• Mvura

Ramba uchitora mishonga yako kutoti chiremba wako akakuudza neimwe nzira.

Iwe unozofanirwa kubvunza mupi wako kana iwe uchifanira kurega kutora mapiritsi esimbi kana zvinwiwa mazuva mashoma pamberi pekuedzwa, kunze kwekunge mupi wako akakuudza kuti zvakanaka kuti uenderere mberi. Simbi inogona kuita kuti chigaro chako chisvike nhema. Izvi zvinoita kuti zviomere chiremba kuti aone mukati memukati mako.

CT neMRI scanners vane hanya nesimbi. Usapfeke zvishongo pazuva rebvunzo yako. Iwe unozokumbirwa kuti uchinje kunze kwembatya dzako dzemumugwagwa uye upfeke hanzu yechipatara yemaitiro.

Iyo x-ray haina kurwadziwa. Kupomba mweya mukati mekoni kunogona kukonzera kupwanya kana gasi kurwadziwa.

Mushure bvunzo:

• Iwe unogona kunzwa kubhururuka uye uine hunyoro mudumbu kupwanya uye kupfuudza yakawanda gasi.
• Iwe unofanirwa kukwanisa kudzokera kune zvako zvenguva zviitiko.

VC inogona kuitwa nekuda kwezvikonzero zvinotevera:

• Kutevera-kenza yekoloni kana polyps
• Kutambudzika kwepamuviri, shanduko mukufamba kwematumbu, kana kuonda
• Anemia nekuda kwesimbi yakaderera
• Ropa muzvituru kana dema, mira zvituru
• Screen yekenza yekoloni kana rectum (inofanirwa kuitwa makore ese mashanu)

Chiremba wako angangoda kuita yakajairwa colonoscopy pane iyo VC. Chikonzero ndechekuti VC haibvumidze chiremba kuti abvise masampuli esuru kana polyp

Dzimwe nguva, VC inoitwa kana chiremba wako aisakwanisa kufambisa chubhu inochinjika nzira yese kuburikidza nekoloni panguva yenguva dzose colonoscopy.

Zvakajairika zvakawanikwa mifananidzo yehutano hwemukati matumbo.

Zviitiko zvisina kujairika zvekuyedza zvinogona kureva chero cheanotevera:

• Kenza yakajeka
• Mabhegi asina kujairika pamadziro ematumbo, anonzi diverticulosis
• Colitis (yakazvimba uye yakazvimba ura) nekuda kwechirwere cheCrohn, ulcerative colitis, hutachiona, kana kushomeka kweropa kuyerera.
• Lower gastrointestinal (GI) kubuda ropa
• Polyps
• Bundu

Nguva dzose colonoscopy inogona kuitwa (pazuva rakasiyana) mushure meVC kana:

• Hapana chikonzero chekubuda ropa kana zvimwe zviratidzo zvakawanikwa.VC inogona kupotsa mamwe madiki matambudziko mukoloni.
• Matambudziko anoda biopsy akaonekwa paVC.

Ngozi dzeVC dzinosanganisira:

• Kuratidzira kune radiation kubva kuCT scan
• Nausea, kurutsa, kuzvimba, kana kukanganiswa kwese kubva kumishonga inoshandiswa kugadzirira bvunzo
• Kukanganiswa kwemukati kana iyo chubhu yekupomba mweya ichiiswa (zvisingaite).

Misiyano pakati peyakajairika uye akajairwa colonoscopy anosanganisira:

• VC inogona kuona iyo colon kubva kumakona mazhinji akasiyana. Izvi hazvisi nyore neyakajairwa colonoscopy.
• VC haidi sedation. Iwe unogona kazhinji kudzokera kumabasa ako akajairwa ipapo ipapo mushure mekuyedzwa. Nguva dzose colonoscopy inoshandisa sedation uye kazhinji kurasikirwa kwezuva rebasa.
• VC uchishandisa CT scanner inokuratidzira iwe kune radiation.
• Nguva dzose colonoscopy ine njodzi diki yekutsvaira ura (kugadzira misodzi shoma). Iko hakuna ingangoita njodzi yakadai kubva kuVC.
• VC kazhinji haigone kuona polyps diki pane gumi mm. Yakajairwa colonoscopy inogona kuona polyps eese saizi.
