See the Admission dates are still on hold due to the covid scenario. But I would recommend you to visit the colleges official website and check regularly about the updates for admission.

Now some colleges may have entrance test or a merit based test which you have to check in the website of your preferred institute. In general you should try to score above 60% atleast to be eligible for Radiology.

Some of the colleges for Radiology:

Sri Guru Ram Das University of Health Sciences, Amritsar

CT University, Ludhiana

RIMT University, Gobindgarh
