Amakhamera Amasha Namadala Alingana Nembile - Abesifazane Abancanyana Abaningi Inzuzo
Umshini we-digital mammogram usebenzisa ukucindezela kanye nama-x-ray ukuze afane nesifuba sakho, kodwa kunokuba athathe isithombe kwifilimu njengendabuko yendabuko, isithombe sithunjiswe kwikhompyutha njengefayela lezithombe zedijithali. Ebizwa nangokuthi i-full-field mammogram (FFDM) egcwele-field, lobu buchwepheshe buqhathanisa kahle nefilimu mammography futhi buzosiza abesifazane abasebasha kakhulu.
Izinzuzo ze-Digital Mammography
Ama-mammogram adijithali ayashesha kunamammogram , ngoba ayikho ifilimu yokuthuthukisa. Isithombe singathunyelwa ngokushesha ku-radiologist sokubuka. Uma isithombe singacacile, uzotshelwa ngakho ngaso leso sikhathi, futhi isithombe singabuye sithathwe. Lokhu kungasiza ekunciphiseni ukushaywa kwe-mammogram, nokucindezeleka ezigulini. I-National Cancer Institute yenza ucwaningo ngokuqhathanisa ifilimu ne-digital mammography, futhi yaphetha ngokuthi i-digital mammography inembile kakhulu kunefilimu ekutholeni umdlavuza kwabesifazane abangaphansi kweminyaka engu-50 ubudala, nabesifazane abanomzimba obukhulu (hhayi amafutha). I-Digital mammography isebenzisa imisebe encane kune-movie yendabuko yammography, ukunciphisa ukuchayeka kwakho kokuphila kwimizuzu yama-x.
Ukwenza okuningi nge-Digital Mammogram Images
Uma izithombe zakho ze-mammogram zisekhompyutheni, i-radiologist yakho ingababuka kumqapha, njengoba nje ubheka izithombe zedijithali. Ekhompyutheni, i-radiologist yakho ingakwazi ukuhlola ngokucophelela izithombe ngokusondela, ukulungisa ukukhanya kwesithombe, noma ukushintsha umehluko, okwenza zonke izici zesifuba zilula ukubona.
Uma udokotela wakho efuna ukubonisana nesifuba sebele mayelana nama-mammograms akho, amafayela wesithombe sedijithali angathunyelwa kwamanye amasayithi ukuhlolwa (telemammography). Ukutholakala kwekhompiyutha nokuxilongwa (CAD) kungasetshenziswa ezithombeni zedijithali ukusiza udokotela wakho ahlaziye zonke izithombe, futhi afake izindawo ezidinga ukutadisha okusondelene.
I-CAD ingathola izicubu ukuthi i-radiologist ingase ingaboni. Uma ukuhlaziywa kwe-CAD kwenziwe, isazi se-radiologist sizokwenza ukuhlola okubonakalayo kwalezo zindawo, futhi ngokusekelwe ekuqeqeshweni nasekuhlangenwe nakho, kunquma ukuthi ubuningi bungaba bunzima kangakanani.
I-Stereo Digital Mammography yenza izithombe ezintathu
Emkhakheni wokucwaninga, ama-stereo digital mammograms ayenziwa ekuhlolweni kwamakhambi kwabesifazane ababuye babuyiselwe ngemva kokuvama kwemvelo okungavamile. I-stereo mammogram yedijithali ihlanganisa amathumbu ama-digital ama-x-ray athathwa ema-angles ahlukene, futhi akhiqize isithombe esilandelayo sesithathu esakhiweni sangaphakathi sebele. Izithombe ezinjalo ze-stereo kumele zibhekwe esiteshini esikhethekile somsebenzi owaziwa yi-radiologist oqeqeshiwe ngokukhethekile. Ucwaningo luholwa uDkt. David J. Getty weBBN Technologies waseCambridge, iMisa, futhi waboniswa eRadioological Society yaseNyakatho Melika ngoNovemba 2007. "Esifundweni sethu, i-stereo digital mammography yanciphisa amathuba amanga ngamaphesenti angu-49," kusho uDkt. I-Getty. "Lokhu kungaba nethonya elikhulu ekunqumeni isigamu senani labesifazane abakhumbula ngokungadingekile ngezinhlelo zokusebenza ezengeziwe zokuxilonga, okubangela ukugcinwa okukhulu kwezindleko nokukhathazeka kwesiguli."
Isivivinyo sokucubungula i-Digital Mammographic Imaging Screening
I-American College of Radiology Imaging Network (ACRIN) ihlangane neNational Cancer Institute ngo-2001 ukuze iqhube isifundo esiqhathanisa ifilimu ne-digital mammography.
Ucwaningo lubizwa ngokuthi i-Digital Mammographic Imaging Screening Trial (DMIST). Lolu cwaningo lwabamba iqhaza labahlanganyeli abangu-49 500, bonke abathola amafilimu namademogram kanye nokufunda okulandelwayo. Ngakho-ke lobu buchwepheshe buqhathanisa kanjani?
- Ifilimu nama-mammogram adijithali anembile yokuhlola okufanayo kubantu abaningi
- Amanani amabizo amanga (ukuxilongwa okungalungile komdlavuza) ayefana nazo zombili izindlela
- Bobabili ubuchwepheshe banembile engu-92% ekuqapheleni umdlavuza webele
Abanye besifazane bayazuza kakhulu kunabanye, futhi bahlangabezana nalokhu okungenani okukodwa kwezi ziqu:
- Uneminyaka engaphansi kwengu-50 ubudala, kungakhathaliseki ukuthi isifuba sini
- Noma yibuphi ubudala, obukhulu kakhulu, noma izicubu ezincelisayo kakhulu zesifuba (izicubu ezincane kakhulu)
- Abesifazane besandulela noma abesilisa, kungakhathaliseki ubudala
Ukuqhathanisa Izindleko Nokutholakala
I-film mammography iyatholakala kakhulu, futhi ihlanganiswa nabanikezeli bomshuwalense wezempilo abaningi. I-Digital mammography isivele itholakala emadolobheni amaningi amakhulu nezindawo eziseduze, kodwa ingatholakali yonke indawo nje okwamanje. Izinhlelo ze-Digital mammography zibiza cishe izikhathi ezingu-1.5 kuya kwezi-4 kunezinhlelo zefilimu. Izinkampani eziningana ezahlukahlukene zenza izinhlelo ze-digital mammography ezinikezwe imvume ye-FDA.
Umlayezo Wokuthatha Umndeni Ngezimpawu Zamamamitha Adijithali
Ifilimu yendabuko yefilimu yenzelwe iminyaka engu-35, ngezinga eliphezulu lokuphumelela. Kufanele ube nesimiso sakho saminyaka yonke esimisweni, kungakhathaliseki ukuthi ungenawo ubuchwepheshe be-digital noma cha. Ukususa i-mammogram kudonsa ukuqhathaniswa konyaka nemiphumela yakho yangaphambilini. Uma ngabe ubukhulu bakho obuvamile bubukwa kwifilimu, awudingi ukuthola isithombe sedijithali senzeke kahle - uma i-digital mammography iyatholakala kuwe ngonyaka olandelayo, izoqhathaniswa nesifundo sakho sefilimu. Uma uneminyaka engaphansi kwengu-50 ubudala, i-premenopausal, noma unezicubu ezincelisayo zesifuba, uzothola ngokubheka i-digital mammography, futhi kufanele uyisebenzise, uma itholakale kuwe.
