The exhaustive board-prep resource for Radiology & Cardiology fellows.
Magnets, Protons, and Alignment
Learn why humans are essentially millions of spinning magnets and how we align them with a B₀ field.
RF Pulses and Excitation
Discover how we disturb equilibrium with RF pulses to create measurable signal.
T1, T2, and Tissue Contrast
Understand the two independent relaxation processes and how they create contrast.
Gradients and K-Space
How we turn physics into pictures using spatial encoding and the Fourier Transform.
Boards-Level Troubleshooting
Identify and fix common scan failures like Aliasing, Chemical Shift, and Metal artifacts.
Quantitative Hemodynamics
Master Phase Contrast physics and VENC optimization for valve and shunt assessments.
The MRI Tradeoff Triangle
Balance SNR, Resolution, and Time using NEX, Bandwidth, and Parallel Imaging.
Hardware and Devices
Prospective vs Retrospective gating, SAR limits, and managing MR-conditional pacemakers.
Parametric Mapping & ECV
Go beyond visual images to calculate T1/T2 maps and quantify diffuse fibrosis with ECV logic.
Diffusion & Spectroscopy
Explore the cutting edge of clinical CMR: cellular diffusion and energetic spectroscopy (P31).
Master Diagnostic Lab
The Physicist's Exam: Integrate 15+ variables from TR to Field Strength in a single diagnostic cockpit. Balance SNR, Time, and Artifacts.
