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
The BI-RADS scoring for mammograms can be comparable to the triple test score's scoring for mammograms. [2] For instance, a BI-RADS of 1 or 2 is equivalent to a triple test score of 1. 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 ...
A similar paper in European Radiology found that when correlated with histopathology, PI-RADS v2 correctly identified 94-95% of prostate cancer foci ≥0.5 mL, but was limited for the assessment of GS ≥4+3 (significant) tumors ≤0.5 mL; in their series, DCE-MRI offered limited added value to T2WI+DW-MRI.

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 Liver Imaging Reporting and Data System (aka LI-RADS) is a quality assurance tool created and trademarked by the American College of Radiology in 2011 to standardize the reporting and data collection of CT and MR imaging patients at risk for hepatocellular carcinoma (HCC), or primary cancer of the liver cells.

The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1] [2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1]
Thus, for example, the RBE for alpha radiation is 2–3 when measured on bacteria, 4–6 for simple eukaryotic cells, and 6–8 for higher eukaryotic cells. According to one source it may be much higher (6500 with X rays as the reference) on ovocytes. [ 3 ]
Compared to the National Early Warning Score from the UK, Q-ADDS had a higher rate of prediction of deterioration (46.5% Q-ADDS vs 40.8% NEWS) but a higher rate of false-positives (3.2:1 Q-ADDS vs 2.4:1 NEWS). [12] The efficacy of EWSs in improving patient outcomes is also reliant on a number of personal and structural factors.
