Self-reported Pain Associated With Screening With Digital Breast Tomosynthesis

Suhaimi, Mohamed, Ahmad, Chelliah

“Reduced compression force in DBT reduces anxiety and pain levels without compromising image quality.”

Breast compression and reported pain during mammographic screening

Moshina, Sagstad, Sebuødegård, Waade, Gran, Music, Hofvind

“Mean score of experienced pain was 2.2, whereas 6% of the women reported severe pain (≥7) during the examination. High body mass index (BMI) (≥27.3 kg/m2) was associated with a higher RR of pain scores ≥7 (RR 1.86, 95%CI 1.02-3.36) compared to medium BMI (23.7-27.2 kg/m2).”

Breast compression and experienced pain during mammography by use of three different compression paddles

Moshina, Sebuødegård, Evensen, Hantho, Iden, Hofvind

“The mean of experienced pain did not differ for the study and flexible paddle (2.5 on NRS), and was lower for the study paddle compared to the fixed paddle (2.4 versus 2.6 on NRS, p < 0.05) .. The majority of women reported low scores of experienced pain during mammography, independent of compression paddle used.”

The impact of compression force and pressure at prevalent screening on subsequent re-attendance in a national screening program

Moshina, Sebuødegård, Holen, Waade, Tsuruda, Hofvind

“Overall, 27,197 (87.1%) women re-attended the program. Re-attendance was highest for women who received a compression force of 10.0–13.9 kg (87.5%) or pressure of 9.0–17.9 kPa (87.8%) and lowest for those who received a compression force of < 10.0 kg (85.0%) or pressure of < 9.0 kPa (84.7%).”

Is breast compression associated with breast cancer detection and other early performance measures in a population-based breast cancer screening program?

Moshina, Sebuødegård, Hofvind

“High compression force and low compression pressure were associated with more favorable early performance measures in the screening program.”

Mammographic compression in Asian women

Lau, Aziz, Ng

“Very strong and highly significant correlations were observed between compression pressure and breast contact area … Current force-standardized protocols … led to highly significant variable compression force and compression pressure between and within Asian women… “

Influence of breast compression pressure on the performance of population-based mammography screening

Holland, Sechopoulos, Mann, den Heeten, van Gils, Karssemeijer

“Percent dense volume increased with increasing pressure, while breast volume decreased … Results suggest that if too much pressure is applied during mammography this may reduce sensitivity. In contrast, if pressure is low this may decrease specificity.”

Accuracy of mammography dosimetry in the era of the European Directive 2013/59/Euratom transposition

Gennaro, Bigolaro, Hill, Stramare, Caumo

“Patient-specific mean glandular dose, possibly adjusted for system calibration, allows more accurate individual breast dosimetry than what would be performed using organ dose provided by manufacturers.”

Radiation dose with digital breast tomosynthesis compared to digital mammography: per-view analysis

Gennaro, Bernardi, Houssami

“Our findings show a modest increase of radiation dose to the breast by tomosynthesis compared to FFDM. Given the emerging role of DBT, its use in conjunction with synthetic 2D images should not be deterred by concerns regarding radiation burden, and should draw on evidence of potential clinical benefit.”

Study on factors intrinsic to the patient that influence the average glandular dose in 2D and 3D mammography

Engler, Attie, Paixão Reis, Squair, Chevalier, do Socorro Nogueira

“Mean Glandular Dose (MGD) is the dosimetric quantity used to estimate the radiation dose to which a patient is exposed when performing a mammography examination … Breast tomosynthesis images of 660 patients were analyzed using Volpara software. From this analysis, the volumetric breast density (VBD) and the MGD were obtained. Patient age and compressed breast thickness (CBT) were obtained from the DICOM header of the images … The results show that CBT is the factor most related to the MGD increase. VBD is the factor with the least impact and the patient’s age has an inverse relationship with the MGD.”
