I had a MRI last week for my spine. I got a call today that I'm having a CT-scan tomorrow for my abdomen (unrelated issue). The day after tomorrow, I'm having X-rays done on my teeth at the dentist because I cracked my teeth. These are all unrelated medical issues. But all these medical issues required medical-imaging that happened to be scheduled within 7 days of each other.
Is it dangerous to have a MRI, CT-scan, and an X-ray all within a week's period? Are they all radioactive? Also, I had an ultrasound 2 weeks ago (which was unhelpful --- which is why I'm now having the CT-scan).
