Bosniak Calculator

In 2019, the Bosniak classification of cystic renal masses, originally developed for computed tomography (CT), underwent a major revision to incorporate magnetic resonance imaging (MRI) and is referred to as Bosniak classification version 2019. Due to the complexity of the new iteration of the Bosniak classification v2019, this calculator has been developed as a support tool to help arrive at the correct Bosniak Class in a wide variety of scenarios covered by the new classification.
