Comparison of Anode/Filter Combinations in Digital Mammography with Respect to the Average Glandular Dose

Abstract

Applying a W/Rh beam quality permits the reduction of the patient dose by approximately 50 % when using an FFDM system based on amorphous selenium. The dose reduction becomes larger as the breast thickness increases. The results are in agreement with simulations and phantom studies known from the literature.

A technique optimization protocol and the potential for dose reduction in digital mammography

“…These include Monte Carlo simulations, 16,[24][25][26] experimental studies using objective image quality metrics, 2,8,14,21,25,27,28 taskbased observer evaluations using anthropomorphic and other phantoms with relevant simulated features, 16,17,19,[29][30][31] and even retrospective or prospective clinical mammography studies employing large patient populations. 23 Monte Carlo studies have been particularly useful in permitting practical comparative evaluation of the existing and proposed target/ filter combinations for imaging breasts of various thicknesses and densities without requiring an unduly burdensome number of experimental studies. However, Monte Carlo simulation approaches have their limitations and require independent experimental validation.…”

Breast tomosynthesis: Dosimetry and image quality assessment on phantom

“…A partially visible insert was scored 0. 5 expressed as a rate, the number of visible inserts over the total number of inserts.…”

“…By comparison with screen-film radiography, digital mammography improves breast cancer screening [1][2][3], reduces average glandular dose [2][3][4][5] by about 22% [4] and makes it possible to add tomosynthesis in routine use [6]. The combination of tomosynthesis with digital mammography increases diagnostic accuracy [6][7][8][9][10][11][12][13][14][15] and reduces recall rates by 30 to 40% [8,9].…”

RöFo: Ausblick und Herausforderungen für die Zukunft

“…Während in der Laienpresse die Brustkrebsfrüherkennung seit der Einführung des deutschen Mammografie-Screening-Programms immer wieder im Mittelpunkt steht, erhielten wissenschaftliche RöFo-Artikel aus dem Vergleichszeitraum, gemessen an der Zitathäufigkeit, bislang vergleichsweise geringe Aufmerksamkeit in der Literatur. Die am häufigsten zitierten Artikel aus dem Jahre 2009 fanden bislang noch nicht häufiger als viermal Erwähnung in der Fachliteratur [49,50]. Anders sieht die Situation bei den Online-Zugriffen aus: 4 Artikel wurden von den RöFo-Lesern überdurchschnittlich oft abgerufen: Im Artikel zur Ganzkörper-MRT in der präoperativen Diagnostik des Mammakarzinoms [51] wird eine Alternative zu den nuklearmedizinischen Stagingmethoden aufgezeigt.…”
