Establishment of beam qualities for medical applications (mammography and CT) in the gamma and X calibration laboratory of CNESTEN according to EN 61267 standards
Appl Radiat Isot. 2024 Apr 15;209:111325. doi: 10.1016/j.apradiso.2024.111325. Online ahead of print.ABSTRACTThe present study aimed to validate the different radiodiagnostic beam qualities (RQT, WAH and WAV) by the measurements of the X-ray beams HVL of a HOPEWELL generator, X80-225 kV from a high voltage range of 10 at 200 kV, at CNESTEN Gamma and X Calibration Laboratory. The experiments were carried out using the PTW TN 32005 ionization chamber, established at 100 cm from the center of the X-ray tube and connected to a SUPERMAX electrometer. The HVL values were measured by applying the attenuation law to the flow of Ka...

Efficient Strategies for Targeted and Second-Look Ultrasound: Enhancing Visualization and Simplifying Techniques
This article addresses the complexities involved in targeted ultrasound for lesions identified in mammograms and MRIs. We aim to provide clarity and guidance in performing targeted ultrasound by utilizing simple schematics and adopting a case-based approach.Recent FindingsTargeted ultrasound is a vital component of diagnostic breast imaging, particularly for nonpalpable abnormalities detected on mammograms. In addition, with the increasing use of MRI in high-risk screening and staging breast cancer, second-look ultrasound is increasingly employed to evaluate incidental findings from MRI and guide tissue sampling, offering ...

Current Imaging Approaches in Inflammatory Breast Cancer
AbstractPurpose of ReviewInflammatory breast cancer (IBC) is a rare and aggressive type of breast cancer with a rapid clinical onset and a poor prognosis. The nonspecific clinical criteria have resulted in a difficult and delayed diagnosis of this rare disease. Radiologists ’ awareness of the appropriate imaging modalities and features of IBC can improve prompt diagnosis, accurate staging of this aggressive disease, and early detection of distant metastases.Recent FindingsDiffuse erythema and severe breast edema involving over one-third of the breast may obscure an identifiable mass on mammography and ultrasound (US) in ...

A Novel Structure Fusion Attention Model to Detect Architectural Distortion on Mammography
AbstractArchitectural distortion (AD) is one of the most common findings on mammograms, and it may represent not only cancer but also a lesion such as a radial scar that may have an associated cancer. AD accounts for 18 –45% missed cancer, and the positive predictive value of AD is approximately 74.5%. Early detection of AD leads to early diagnosis and treatment of the cancer and improves the overall prognosis. However, detection of AD is a challenging task. In this work, we propose a new approach for detecting a rchitectural distortion in mammography images by combining preprocessing methods and a novel structure fusion...

Inter- and intra-observer variability of qualitative visual breast-composition assessment in mammography among Japanese physicians: a first multi-institutional observer performance study in Japan
CONCLUSIONS: Qualitative visual assessment of mammographic breast composition using the new Japanese classification revealed excellent intra-observer reproducibility. However, persistent inter-observer variability, presenting a challenge in establishing it as the gold standard in Japan.PMID:38619787 | DOI:10.1007/s12282-024-01580-8 (Source: Breast Cancer)

Diagnostic value of qualitative and quantitative enhancement parameters on contrast-enhanced mammography
CONCLUSION: Diagnostic accuracy of quantitative parameters was higher than that of qualitative parameters. High CNR, rim enhancement, and descending pattern were features commonly seen in malignant lesions, while low CNR, homogeneous enhancement, and ascending pattern were commonly seen in benign lesions.PMID:38619006 | DOI:10.4274/dir.2024.232472 (Source: Diagnostic and Interventional Radiology : The Turkish Society of Radiology)
