The radiology calculators developed by Dr. Amar Udare are not only widely used by many radiologists worldwide but are also personally used daily by Dr. Udare himself. He has personally verified and tested these tools in his clinical practice to ensure their accuracy and practicality. These tools implement current, widely adopted frameworks such as TI-RADS, O-RADS, Fleishner recommendations, Bosniak 2019, and others, to reflect the latest reporting standards. They are designed to assist radiologists and trainees in routine reporting and decision-making, supporting clinical judgments with validated calculations, all of which Dr. Udare continuously reviews and updates based on his ongoing professional experience.
