MRI Plan is an interactive educational training tool designed for MRI technologists, students, and professionals who want to practice and strengthen their MRI planning skills. MRI Plan focuses specifically on MRI planning. It does not teach MRI physics or anatomy as standalone subjects. Instead, the app is dedicated to the practical skills involved in planning MRI exams and protocols, including slice positioning, angulation, coverage, and field of view (FOV). Instead of only reading about slice positioning, MRI Plan lets you practice it. Work through MRI exams and protocols using an interactive planner where you can adjust slice position, angulation, coverage, and field of view (FOV). Step-by-step guidance, visual feedback, hints, and explanations help you understand not only where to place slices, but why. PRACTICE MRI PLANNING • Practice slice positioning and angulation on MRI images • Adjust coverage and FOV • Work with axial, sagittal, coronal, and oblique planning • Receive immediate feedback as you practice • Review hints and detailed teaching explanations • Track your learning progress EXPLORE MULTIPLE MRI EXAMS Practice planning across a growing library of MRI exams and protocols, including brain, spine, musculoskeletal, abdomen, pelvis, and other commonly performed MRI studies. LEARN AT YOUR OWN PACE MRI Plan is designed to make planning practice available outside the scanner. Repeat a planning step as many times as needed, explore different protocols, and build confidence through hands-on practice. FOR MRI STUDENTS AND TECHNOLOGISTS Whether you are learning MRI planning for the first time, preparing for clinical training, or refreshing your planning skills, MRI Plan provides a structured environment for continued practice. Some learning content is available free. A Pro subscription unlocks access to the full available library of MRI planning content. MRI Plan is an educational and training application only.
