The Chicago Radiological Society is a division of the Illinois Radiological Society (IRS), which in turn is a state chapter of the American College of Radiology (ACR). To be a member of CRS, you must be a member of ACR and IRS.
Currently, it costs a radiologist $750 a year to join ACR, $105 to join
IRS, and $45 to join CRS, a total of $900 annually to be a member of all
three organizations. Since this and other details of membership are subject
