Nope! For BSc Radiology you have no need to do MBBS. The Eligibility for the BSc in Radiology are:

• The student should have completed 10th and 12th from a recognised board or university.
• The student should have obtained a minimum of 50% at the 10+2 level.
• It is compulsory for the student to have a background in science.

So if you satisfy all this criterions you are eligible for the course.

*The eligibility mentioned are true for all colleges but some colleges may have higher marks need like 60% or 75% which is entirely dependent on the college.

**If you want to be a MD Radiology then the MBBS is a must.
