CAT scan while pregnant

Crystal
I have a clotting disorder and because of chest pain I had to get a ct scan to check my lungs for a possibly life threatening clot. My high risk doctor decided it was in mine and babies best interest to get the scan done, I wanted decline because I didn't want to expose my baby girl to any type of radiation but my husband and doctor insisted because if it were to be a clot and it was bad enough I could die and baby would too. I gave in and luckily it was just pleurisy pain from lupus. They said baby is at minimal risk because I am almost 25 weeks. Has anyone else had a scan like this while pregnant? I need some reassurance. 😢
