Have I Met with an IR Doctor Before?

If you have ever had a biopsy of a suspicious internal lesion, a port placement for intravenous access, or had an issue with massive blood loss, you may have already met an IR doctor and did not know it!  Though the field of Interventional Radiology is 70 plus years old, it is expanding rapidly and the once traditional cut-surgery is being found to have better outcomes with minimally invasive options with IR!
