Standard screening mammography includes two views: craniocaudal and mediolateral oblique. In the mediolateral oblique projection a central beam angle can varies between 30° and 60°. Patients and methods. We compare the thickness of the compressed breast, time-current product, exposures and image quality in two different mammographic oblique views: 45° versus 60°. Ourstudy population consisted of 33 women in whom additional 60° films after standard 45° films were obtained for the objective diagnostic reasons. Results. The mean thickness of the compressed breast was significantly lower with an angle of 60° than with an angle of 45° (47.8 vs. 50.7 mm, p<0.01); themean time current product and the mean breast exposure were significantly lower with an angle of 60° than with an angle of 45° (42.6 vs. 46.7 mAs, p<0.01; 0.67 vs. 0.78 mGy, p<0,01). The difference in the image quality has not reached statisticaI significance (but it exists!). Conclusions. By introducing 60° films instead of commonly used 45° films, mammograms of at least the same quality can be obtained with lower radiation dose, which is of great importance when we remind the great radiosensitivity of glandular breasttissue"},{"@xml:lang":"sl","#text":"Izhodišča. Pri standardnem presejalnem testu z mamografijo uporabljamo dvoje projekcij: kraniokavdalno in mediolateralno polstransko. Pri mediolateralni polstranski projekciji je kot centralnega žarka od 30° do 60°. Bolniki in metode. Primerjali smo debelino komprimirane dojke, zmnožek časa in električnega toka, izpostavljenost sevanju in kakovost slik pri dveh različnihmamografskih poševnih projekcijah: pod kotoma 45° in 60°. Preiskave smo naredili pri 33 ženskah, pri katerih smo zaradi diagnostičnih zahtev polegslikanja pod kotom 45° naredili tudi slikanje pod kotom 60°. Rezultati. Srednja vrednost debeline komprimirane dojke je bila pri slikanju pod kotom 60° statistično značilno nižja kot pod kotom 45° (47,8 vs. 50,7 mm, p<0.01); pravtako sta bili tudi statistično značilno nižji srednji vrednosti zmnoška časa in eletričnega toka ter izpostavljenosti sevanju (42,6 vs. 46,7 mAs, p<0.01; 0,67 vs. 0,78 mGy, p<0.01). Našli smo tudi razliko v kakovosti slik, ki pa ni bila statistično značilno boljša. Zaključki. Z uporabo polstranske mamografske projekcije pod kotom 60°smo dosegli vsaj enako kakovost mamografskih slik ob nižji sevalni dozi, kar je zelo pomembno, saj je mlečna žleza v dojki zelo radiosenzitivna"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-PJVBDB0P","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-PJVBDB0P"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-PJVBDB0P/1c859085-9f32-498c-883a-82be2eb40081/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Društvo radiologije in onkologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-PJVBDB0P/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-PJVBDB0P"}}}}
