Currently, there is marked discrepancy between the costs of performing cardiac CT and the renumeration provided for this. Until this is addressed, cardiac CT will not reach its potential for the benefit of patients. It is for this reason that the SCCT continues to dedicate significant efforts to represent the need of the cardiology and radiology communities in bringing about changes in policy and billing.
