Automated breast ultrasound (ABUS) is an ultrasound technique that tends to be increasingly used as a supplementary technique in the evaluation of patients with dense glandular breasts. Patients with dense breasts have an increased risk of developing breast cancer compared to patients with fatty breasts. Furthermore, for this group of patients, mammography has a low sensitivity in detecting breast cancers, especially if it is not associated with architectural distortion or calcifications. ABUS is a standardized examination with many advantages in both screening and diagnostic settings: it increases the detection rate of breast cancer, improves the workflow, and reduces the examination time. On the other hand, like any imaging technique, ABUS has disadvantages and even some limitations. Many disadvantages can be diminished by additional attention and training. Disadvantages regarding image acquisition are the inability to assess the axilla, the vascularization, and the elasticity of a lesion, while concerning the interpretation, the disadvantages are the artifacts due to poor positioning, lack of contact, motion or lesion related. This article reviews and discusses the indications, the advantages, and disadvantages of the method and also the sources of error in the ABUS examination.

“…Mamografija se kao inicijalna metoda u obradi dojke koristi već nekoliko desetljeća te je prihvaćena kao metoda probira. Prema dobro dokumentiranim studijama, provođenjem NPP-a ranog otkrivanja raka dojke snižen je mortalitet te je mamografija jedina metoda koja dokazano smanjuje smrtnost od karcinoma dojke 14 17 . Usprkos statistički značajnoj razlici u AGD-u između 2D i DBT-a, ona je unutar granica dozvoljenih i očekivana, kao što su pokazali rezultati niza znanstvenih studija [15][16] .…”

Sažetak. Cilj:Osnovni cilj našeg istraživanja je usporedba doznih parametara i debljine komprimirane dojke kod mamografskog pregleda koji je izvršen digitalnom tomosintezom (engl. digital breast thomosynthesis; DBT) i standardne, 2D mamografije. Ispitanici i metode: U istraživanje je uključeno 200 ispitanica životne dobi od 40 do 81 godine (median 60,5 ± 10,6). Ispitanice su podijeljene u dvije skupine, ovisno o vrsti mamografskog pregleda. Ova retrospektivna analiza obuhvatila je pretrage koje su vršene na mamografskom uređaju Hologic Selenia Dimensions (Hologic, Bedford, Mass) u razdoblju od 1. veljače 2018. do 30. ožujka 2018. Rezultati: Hi-kvadrat testom isključila se statistički značajna razlika u gustoći parenhima dojki između dviju grupa ispitanica. T-test nije pokazao statistički značajnu razliku u dobi ispitanica, kao niti razlike u debljini komprimiranih dojki između dviju ispitanih skupina. Vrijednost srednje glandularne doze (engl. average glandular dose; AGD) kod DBT-a u odnosu na 2D mamografiju bila je viša 0,53 mGy za lijevu dojku, a 0,37 mGy za desnu dojku (3,83 / -1 mGy, p = 0.001; 3.82 / -0.9 mGy, p = 0.023). Zaključak: Usprkos statistički značajnoj razlici u AGD-u kod DBT-a u odnosu na 2D mamografiju između dviju skupina ispitanica, ona je unutar granica prihvatljivosti propisanih Pravilnikom o uvjetima za primjenu izvora ionizirajućeg zračenja u svrhu medicinskog i nemedicinskog ozračenja (NN 42/2018(NN 42/ , 9. 5. 2018, stoga smatramo da je opravdano uvođenje DBT-a kao standardne radiološke metode pregleda dojki. Abstract. Aim:The main goal of our research is to compare the thickness of the breast and the parameters of DBT and standard 2D mammography. Respondents and methods: The study included 200 respondents with an age range from 40 to 81 years, (median 60,5 ± 10,6). The respondents are divided into 2 groups depending on the type of mammograms they were subjected to. This retrospective analysis included tests performed on the mammography device Hologic Selenia Dimensions (Hologic, Bedford, Mass) in the period from February, 1 st till March, 30 th 2018. Results: Hi-square test excluded statistically significant difference in breast density. The T-test didn't show any statistically significant difference in breast thickness between two groups. The mean values of the overall glandular dose of the DBT for left and rigt breast were 0.53 mGy and 0,37 mGy, respectively (3.83 / -1mGy, p = 0.001, 3.82 / -0.9 mGy, p = 0.023). The difference was statistically significant and dose was 20% greater in DBT. Conclusion: Despite the statistically significant difference in the absorbed glandular dose between the two groups, it remains within the limits of acceptability according to the guidelines provided by the Ordinance on Conditions for application of sources of ionizing radiation for the purpose of medical and non -medical irradiation (OG 42/2018(OG 42/ , 9.5.2018.

“…La información obtenida de la adquisición de la tomosíntesis reduce la superposición de estructuras, permitiendo una mejor evaluación, detección, caracterización y localización de las lesiones [7][8][9] (Fig. 1), y disminuyendo de manera importante las tasas de rellamado 4,5,8,10,11 . Como beneficio adicional, reduce la necesidad de obtener mayor número de proyecciones complementarias o estudios adicionales, lo que la hace un estudio más rentable en la práctica clínica en relación con la mastografía digital [12][13][14][15] .…”

Introducción: El tamizaje del cáncer de mama con mamografía convencional tiene limitaciones conocidas. La tomosíntesis es una técnica en la que se adquieren imágenes a bajas dosis de radiación y desde múltiples ángulos. La información obtenida reduce la superposición de estructuras, permitiendo una mejor evaluación, detección, caracterización y localización de las lesiones. Objetivo: Comparar la proporción diagnóstica entre mastografía digital y tomosíntesis. Método: Estudio observacional, retrospectivo, analítico y de corte transversal. Se evaluaron 430 expedientes electrónicos con imágenes de mastografía digital y tomosíntesis, se efectuó análisis de doble lectura y se comparó la visibilidad de hallazgos por ambos métodos de imagen de acuerdo con BI-RADS. Se realizó una diferencia de proporciones en la que se consideró como significativo un valor de p < 0.05. Resultados: Se encontró una diferencia estadísticamente significativa al comparar los hallazgos al analizar únicamente las imágenes obtenidas por mastografía digital en 137 casos, frente a los 400 casos con hallazgos visibles documentados en imágenes de tomosíntesis en una segunda lectura. Se obtuvo un valor Z de 1.8, con p = 0.0329. Conclusiones: Se halló un valor de proporción diagnóstica de la tomosíntesis mayor que el obtenido con la mastografía digital convencional.Palabras clave: Tomosíntesis mamaria. Mastografía digital.
