“…Consistency in the application of breast compression for females attending NHSBSP mammography is important to maintain high standards of image quality throughout the programme [6,7]. Within our study, compression used by practitioners was analysed for different BI-RADS densities and breast volumes to ascertain whether any relationships existed.…”

“…Compression is applied to reduce breast thickness; however, it should be noted that the exact relationship between compression and reduction in breast thickness is neither linear nor clear cut [4]. Thickness reduction minimises radiation burden, lessens superimposition of breast structures and decreases geometric and motion unsharpness [5][6][7]. Overall, thickness reduction is said to improve image quality, thereby heightening the chance of detecting cancer [8][9][10][11].…”

“…Criteria to assess mammography images available in the literature are mainly for mammograms without implants [4,6,15,21,27,46,47] and are related to specific anatomical details that should be included in the images (pectoral muscle, inframammary angle, retroglandular adipose tissue). Sharpness, artefacts, information/labeling, and exposure parameters were also parameters identified in the review that should be assessed to decide if the image is diagnostic.…”

Study of breast implants mammography examinations for identification of suitable image quality criteria

Purpose: To characterise the mammography technique used in breast cancer screening programmes for breast implants (BI) and to identify if the image quality (IQ) criteria available in literature are applicable to BI imaging. Methods: The study was conducted in two phases: literature review to find IQ criteria used in mammography combining keywords in several sources; and assessment of 1207 BI mammograms using the criteria that was identified previously to see if they were achieved or not. An observation grid was used to collect information about positioning, beam energy, compression force, and exposure mode. Descriptive statistics and Student's t test and χ 2 test were performed according to the nature of the variables. Results: Forty-seven out of 2188 documents were included in the analysis, with 13 items identified to assess the quality of positioning, 4 for sharpness, 3 for artefacts, and 2 for exposure parameters. After applying the criteria to BI mammograms, retroglandular fat was not included in 37.3% of the images. The "Pectoral-Nipple-Line" criterion was achieved in 35% of MLO/ML images. The placement of the implant (subpectoral/subglandular) or performing the Eklund had significant influence on the visible anatomy (p = < 0.005), alongside whether the breast was aligned to the detector's centre. Conclusions: Some of the criteria used to assess standard mammograms were not applicable to BI due to implant overlap. The alignment of the image with the detector's centre seems to have an impact on the amount of visible tissue. Further studies are necessary to define the appropriate protocol, technique, and suitable quality criteria to assess BI mammograms.

“…The amount of visible pectoralis muscle determines the amount of breast tissue included in the image which is important to reduce the number of false negatives and to increase the sensitivity of the mammography. In this sense pectoralis muscle should be seen until the level of the posterior nipple line which is drawn tangentially posteriorly from the nipple towards the pectoral muscle on the MM [7].…”

Cystic schwannoma of the axillary region: imaging findings of a rare disease. Case report.

Schwannomas are well capsulated, benign, and slowly growing tumors which originate from Schwann cells of peripheral nerve sheath. The incidence of schwannomas in the axillary region is not common. This rarity causes misdiagnosis at the radiological evaluation. In this case we present the imaging and histopathological findings of a cystic schwannoma located in the axillary fossa of a 47-year-old female patient mimicking complex cyst, lymphadenopathy or hydatid cyst in radiological evaluation. Although lymphadenopathy, lymphatic malformation, lipoma, cyst, hidradenitis suppurativa or dermatofibroma are the most frequent lesions to be considered, peripheral nerve sheath should also be kept in mind in the differential diagnosis of axillary masses.
