Modern day IR is very patient centered and there are some fairly intense patient interactions (end of life issues etc) especially in the interventional oncology population. The lifestyle is far more similar to general surgery then it is to dermatology or anesthesia. We have morning rounds to start the day, inpatient consults , floor work, outpatient clinic and procedures. There is a great deal of patient care issues in my practice and that often goes beyond the initial consult and follow up to include following up on labs, refilling medications, and imaging as well as responding to patient phone calls etc.
If you do not enjoy patient care, I would advise you not to pursue interventional radiology. Diagnostic radiology is an amazing field and the advancements in imaging will allow us to continue to hone our diagnostic ability as a medical community. Imaging and interventional radiology are very closely related and there will be more and more requirements by IR to become very adept at advanced imaging to best counsel their patients on appropriate therapy etc.
