The American College of Radiology (ACR) announced Thursday that it has developed three new guidance documents—two practice parameters and one technical standard—to help radiology practices improve the quality of care they provide to patients.

The practice parameters cover the performance of dopamine transporter SPECT imaging for movement disorders and cardiac PET/CT imaging, while the technical standard covers diagnostic procedures using radiopharmaceuticals. The documents are available now on the ACR’s website at no charge.

The ACR also announced that it has revised 32 other guidance documents for practices to reference.

“Each practice parameter and technical standard represents a policy statement by the ACR,” Matthew Pollack, MD, chair of the ACR Committee on Practice Parameters and Technical Standards, said in a prepared statement. “Each document is an educational tool that addresses the indications, technique, personnel qualifications, and recommended methods of interpretation and documentation specific to its topic. Every practice parameter and technical standard undergoes an extensive review process prior to final approval for publication and dissemination.”

These new and revised documents take effect on Oct. 1.
