Hello,

DNB radiology has 1 theory exam and 3 practical exam. If a candidates clear theory exam then only he/she can appear practical exam. Minimum percentage for pass is 50%.

Theory paper has 10 questions having 10 marks each. In practical exam , it consists of 40 spotters and 4 long cases and 2 table vivas.  if a candidate clear 1st practical exam then only he/she can appear 2nd and same goes for 3rd. There is no minimum pass mark specified as it depends on the performance of candidates. if failed then has to appear practical exam until he/she clears it.

For more information, you can ask the concerned faculty of the college or senior who have already gone through this process.

Hope it helps!
