The assessment categories were initially developed for mammography and later adapted for use with MRI and ultrasound findings. The summary of each category, given below, is nearly identical for all three modalities. Category 6 was added in the 4th edition of the BI-RADS. BI-RADS assessment categories are: [2] 0: Incomplete; 1: Negative; 2: Benign
After describing the findings, the radiologist provides a final assessment ranging from 0 to 6: BI-RADS 0 indicates an incomplete assessment which needs additional imaging. BI-RADS 1 & 2 indicate a negative and benign screen mammogram respectively. BI-RADS 3 indicates probably benign. [53] BI-RADS 4 indicates suspicious for malignancy.
Similar to the triple test score, a lower scoring on BI-RADS (i.e. 1 or 2) is indicative of a benign screening while a high scoring (i.e. 5 or 6) is indicative of malignancy. [2] Unlike the triple test score which scores three different exams, BI-RADS focuses on evaluating findings from one exam: mammograms.
BI-RADS score of 4 or 5 on mammography, ultrasound, or MRI. [11] A suspicious hard palpable lump [9] Skin changes like crusting, scaling, or dimpling of the breast, which may signal an underlying breast cancer [9] Abnormal nipple discharge [7] [9]
The TI-RADS (Thyroid Imaging Reporting and Data Systems) are sonographic classification systems which describe the suspicious findings of thyroid nodules. [12] It was first proposed by Horvath et al., [13] based on the BI-RADS (Breast Imaging Reporting and Data System) concept. Several systems were subsequently proposed and adopted by ...
The phenomenon of finding pre-invasive malignancy or nonmalignant benign disease is commonplace in all forms of cancer screening, including pap smears for cervical cancer, fecal occult blood testing for colon cancer, and prostate-specific antigen testing for prostate cancer. All of these tests have the potential to detect asymptomatic cancers ...
Breast cancer classification divides breast cancer into categories according to different schemes criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes. As knowledge of cancer cell biology develops these ...
Fibroadenoma of the breast is a benign tumor composed of a biplastic proliferation of both stromal and epithelial components. [ 12 ] [ 13 ] This biplasia can be arranged in two growth patterns: pericanalicular (stromal proliferation around epithelial structures) and intracanalicular (stromal proliferation compressing the epithelial structures ...
