CT risk include :-

Harm to unborn babies

A very small dose of radiation

A potential reaction to the use of dyes

Damage DNA and cause cancer

MRI scan risk include :-

Possible reaction to metal due to magnetic power

Increase in body temperature during long scan time

Loud noise from the machine causing hearing issue

The Magnetic field that change with time loud knocking noise

Claustrophobia.

You should consult a doctor before perform MRI if you have implants including:

Eye implants 👀

Artificial joints

An IUD (intra uterine device)

A spcemaker

Benefits
