Access Radiology, Inc., was formed in February 1998 when Rapides Radiology Associates, Inc. and Alexandria Imaging Associates, Inc. merged. This merger was done on a mutual trust and understanding that it would be more advantageous to have 1 group of Radiologists in Central Louisiana servicing the radiological needs of the community. The group is dedicated to providing the community with outstanding, innovative radiological services.
