"The "official" Bosniak classification uses Roman numerals, not Arabic ones, for each category. The use of the term "grade", "stage", "group", "type", or similar for each category is technically incorrect. Version 2019 has switched from "category" to "class" 11."

"Although practised by some, using ultrasonography to characterise the Bosniak classification remains controversial. Originally, it was thought ultrasound was inadequate for the task as it could not show neovascularisation (cf. contrast-enhanced CT/MRI) ref. However, newer studies looking at contrast-enhanced ultrasound suggest this impediment is no longer true ref. There is also evidence that ultrasound has a higher sensitivity for intralesional septa than either CT or MRI 8,13."
