Hello dear,
.
You haven't mentioned have you done both the courses or are you thinking which one is best?
.
Anyhow,let me clear you in both the ways,
BSC in radiology has less income
where MSC in  radiology has good income.
.
If you are only going with BSC then your income will be nearly 7 to 10k per month
Where as MSC has 30 to 50k per month.
.
If you have done with both of the courses then your income will be nearly 40.to.60k per month
