“…This was an expected result, since the anti-scatter grid not only attenuates scattered but also primary radiation, so removing it allows reducing the exposure maintaining the same level of primary radiation. This reduction is observed in both phantom and clinical acquisitions, and is quantitatively similar to that obtained in previous studies (5,14). The dose reduction is greater for thinner breasts.…”

Background In 2014, Siemens developed a new software-based scatter correction (Progressive Reconstruction Intelligently Minimizing Exposure [PRIME]), enabling grid-less digital mammography. Purpose To compare doses and image quality between PRIME (grid-less) and standard (with anti-scatter grid) modes. Material and Methods Contrast-to-noise ratio (CNR) was measured for various polymethylmethacrylate (PMMA) thicknesses and dose values provided by the mammograph were recorded. CDMAM phantom images were acquired for various PMMA thicknesses and inverse Image Quality Figure (IQF) was calculated. Values of incident entrance surface air kerma (ESAK) and average glandular dose (AGD) were obtained from the DICOM header for a total of 1088 pairs of clinical cases. Two experienced radiologists compared subjectively the image quality of a total of 149 pairs of clinical cases. Results CNR values were higher and doses were lower in PRIME mode for all thicknesses. IQF values in PRIME mode were lower for all thicknesses except for 40 mm of PMMA equivalent, in which IQF was slightly greater in PRIME mode. A mean reduction of 10% in ESAK and 12% in AGD in PRIME mode with respect to standard mode was obtained. The clinical image quality in PRIME and standard acquisitions resulted to be similar in most of the cases (84% for the first radiologist and 67% for the second one). Conclusion The use of PRIME software reduces, in average, the dose of radiation to the breast without affecting image quality. This reduction is greater for thinner and denser breasts.

Statistically significant equivalence was shown with an equivalence margin of 0.12% points for cancer detection rate and with an equivalence margin of 0.40% points for specificity. A marked patient dose savings in grid-less acquisition of up to 36% compared to grid-based acquisition was achieved. It can be concluded that grid-less acquisition with software scatter correction is an alternative to grid-based acquisition in mammography.

“…A moving anti-scatter grid is normally used, which is situated just behind the low-attenuation (often carbon-fibre) tabletop and in front of the image receptor. Some designs work without an anti-scatter grid and make a software correction for the largescale effects of scattered radiation in the image [18,19].…”

“…Indirect digital mammography detectors use a two-step process for X-ray detection [6,7,18]. This type of receptor is similar to that commonly employed in digital radiography and consists of a thin crystalline scintillator layer closely coupled to an amorphous silicon microcircuit layer which is supported by a rigid substrate.…”
