MRI 105 — Principles of Magnetic Resonance Imaging Physics
This course provides a comprehensive study of the fundamental principles of magnetic resonance (MR) physics and safety. Students will explore the atomic and molecular structures that form the basis of MR, including nuclear magnetic resonance (NMR) and the alignment of magnetic fields. Key topics include magnetism, resonance theory, spatial encoding, and the interaction between magnetic fields and radiofrequency (RF) pulses, which are critical for MR image formation. The curriculum introduces contrast weighting concepts, including T1, T2, and proton density weighting, and their roles in distinguishing tissue characteristics and enhancing diagnostic value. Factors affecting image quality, such as signal-to-noise ratios, resolution, and contrast optimization, are also discussed. Students will examine imaging techniques and their biological effects, with an emphasis on safety considerations for patients and staff. Additionally, the course compares MRI with other imaging modalities, highlighting distinct functional mechanisms, diagnostic applications, and the advantages and limitations of each in medical imaging.
