4% of mammograms reported as BIRADS 1 and 2 and consequently not seen at the tertiary centre.
The BIRADS 3 lesions have a 2% probability of being malignant.
A receiver-operator analysis showed that for all 12 readers, the combined modality of tomosynthesis and FFDM was superior to FFDM alone when using the forced BIRADS score and the probability of malignancy scale.
In contrast, three-quarters of all contralateral invasive cancers occurred in women who had BIRADS scores of 3 or 4.
and these findings provide further indication for the clinical utility of our flagship test to distinguish benign from malignant lesions in BIRADS 3 and 4 patients," Dr.
The reasons for this are not completely clear, but a common view is that BIRADS is limited in advising how descriptive findings used in the BIRADS Lexicon should be linked to the final BIRADS assessment categories.
22) This observation could have important implications for the radiologist's ability to characterize breast lesions, such as in classification according to the BIRADS system.
Despite the use of several criteria in the classification of MRI-detected lesions and the interpretation of contrast-enhancement kinetics, suspicious BIRADS (breast imaging reporting and data system) IV and V lesions still require histologic diagnosis.
4) BIRADS categories 3 and 4 were combined as indeterminate; patients with these lesions were either asked to return for further imaging examinations and a short-term follow-up examination, or a tissue sample was obtained for pathological examination.
TalkStation Breast Imaging Reporting Module is a BIRADs
compliant speech-enabled reporting system designed to synchronize with radiologist's workflow and simplify the interpretation of breast imaging studies to facilitate reporting and efficient image evaluation.
As a result, biopsy is commonly used by breast imaging radiologists and focused on lesions falling into categories 4 (suspicious) and 5 (highly suspicious) of the BIRADS reporting system.
In this study, 18 women with breast cancer classified as BIRADS 5 identified on mammography or ultrasound underwent a PEM scan and same day PEM-guided biopsy on 24 index and satellite lesions.
