MITA Issues White Paper on XR 29 Compliance Process


Washington, D.C. – The National Electrical Manufacturers Association (NEMA) today published a Medical Imaging & Technology Alliance (MITA) authored white paper entitled, “Is Your CT Smart Dose Compliant?” which clarifies the process for determining whether computed tomography (CT) equipment conforms to XR 29 Standard Attributes on CT Equipment Related to Dose Optimization and Management, also known as MITA Smart Dose CT.

“MITA is pleased to continue efforts to educate CT users and hospitals about the individual requirements of XR 29, while manufacturers support development of further resources to enable informed decisions regarding CT equipment and patient care,” said Thad Flood, JD, industry director of MITA. “This white paper lays out measures as defined by NEMA and MITA for CT users and hospital administrative staff to assess MITA Smart Dose CT compliance so that patients will continue to have access to the safest, most innovative equipment available.”

Beginning in 2016, Medicare will reimburse at a lower rate for certain diagnostic CT scans performed on equipment in a physician’s office or in the hospital outpatient setting that does not meet all four attributes of MITA Smart Dose CT: DICOM Radiation Dose Structured Reporting; CT Dose Check (XR 25); Automatic Exposure Control (AEC), an operational mode that tailors a CT system’s radiation output to the specific body regions; and Pediatric and Adult Reference Protocols, which are a set of scanning parameters. These four key attributes of CT systems are designed to help clinicians with dose optimization and management in order to maintain the standard of care established by professional societies and regulatory agencies.

MITA’s white paper clarifies the process through which CT users and hospital administrators can determine whether their CT equipment conforms to MITA Smart Dose CT and outlines important considerations for assessing system modifications marketed to obtain Smart Dose CT conformance.
