Question Archive

• How are blood pool agents eliminated from the body?

• How do the safety profiles of blood pool agents compare with those of other MR contrast agents?

• What about contraindications for blood pool agents in patients with renal impairment?

• Why is an extended imaging window of importance in MRA?

• I thought almost everyone had learned how to do first-pass MRA with proper bolus timing, so why is this now a problem or at least an issue?

• My dynamic (first-pass) scans are very good. So what is the value of steady-state imaging?

• Can the benefits of blood pool agents also be extended to include users that have lower field MR systems such as the 0.2T and 0.3T open scanners?

• Can vascular imaging with blood pool agents improve MRA images sufficiently to be a potential challenge to conventional XRA or CTA?
