The American Society of Radiologic Technologists (ASRT) has released three new online education modules: Safe CT Practices, Safe MRI Practices, and Low-Dose Computed Tomography.
Safe CT Practices and Safe MRI Practices are designed to help radiologic technologists and facilities meet the Joint Commission's revised CT and MRI safety practice requirements and CT dose reduction requirements, according to ASRT. Both modules are also available in a combo pack for facilities practicing both CT and MRI.
The third new module, Low-Dose Computed Tomography, aims to teach radiologic technologists how to use low-dose CT screening techniques for patients with lung cancer, ASRT said. It also includes guidance for radiology managers seeking to provide reimbursable low-dose CT screening services to Medicare patients.

The CT image is shown in the axial plane. The PMV is automatically extracted using the developed deep learning model and overlayed onto the lungs for visual clarity.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/03/genkin.25LqljVF0y.jpg?auto=format%2Ccompress&crop=focalpoint&dpr=2&fit=crop&h=167&q=70&w=250)
