Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Breast cancer is the most commonly diagnosed cancer worldwide and is the leading cause of cancer-related deaths in women. Mammography, breast ultrasonography (US), and breast magnetic resonance imaging (MRI) are essential for the diagnosis and follow-up of breast cancer. The American College of Radiology Breast Imaging- Reporting and Data System (ACR BI-RADS), which is used worldwide, provides the standard terminology for breast imaging (Jajodia et al., 2021). The ACR BI- RADS lexicon categorizes breast imaging findings into seven BIRADS categories of 0, 1, 2, 3, 4(4a, 4b, 4c), 5, and 6 according to the probability of malignancy. Breast imaging findings assigned as BI-RADS 4 require tissue sampling and histopathological examination. However, the likelihood of malignancy of lesions classified as BI-RADS 4 ranges widely, from 3% to 94%. Categorization of lesions according to BI-RADS is related to the experience of the radiologist, with experienced radiologists performing better than inexperienced radiologists

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A method with lower inter-reader variability for distinguishing benign lesions from BI-RADS 4 lesions needs to be developed to help avoiding unnecessary biopsies. The Kaiser score (KS) is a classification tree flowchart based on machine learning, which can guide clinical decision-making about breast imaging findings on breast MRI. It selects five morphological features and kinetics among 17 categorical diagnostic criteria to score each breast lesion and applies to both mass and non-mass enhancement (NME) lesions. The KS value ranges from 1 to 11, with increasing values indicating higher probability of malignancy. A biopsy is recommended, if the lesion score exceeds 4.

Ductal carcinoma in situ (DCIS), whose incidence has recently increased rapidly, only manifests as suspicious microcalcifications from time to time. Between 70% and 90% of DCIS diagnoses depend mainly on detecting microcalcifications on mammography.The morphology and distribution of microcalcifications are of great significance in distinguishing between benign and malignant micro calcifications. Given its confinement to the milk ducts, DCIS always presents as NME lesions and may be false-negative on MRI. A previous study suggested that the KS should be upgraded in the presence of suspicious mammographic microcalcifications to avoid missed DCIS diagnosis
