Learn MRI the friendly way — from the spin up.
A welcoming, graduate-level course for radiology residents and technologists. No dense slides — just hands-on physics simulators, a friendly 3D scanner, and a viewer full of real MRI scans you can scroll, window and reconstruct yourself. Go at your own pace. 💙

Start anywhere
New to MRI or brushing up — every lesson states its prerequisites and builds gently.
Learn by playing
Turn the knobs. The physics responds instantly, so intuition just clicks.
Real scans, head to toe
Practice on actual MRI — brain, spine, heart, pelvis and foot.
Learn by doing the physics
Every abstract concept is paired with a tool you play with until it becomes second nature.
Head-to-toe Body Atlas
Real MRI from brain to foot — spine, heart, pelvis and limbs, each with a walkthrough.
Bloch simulator
Tip the magnetization and watch T1/T2 relaxation play out in a friendly 3D view.
Live MRI viewer
Real T1/T2/PD/MRA, perfusion and functional volumes. Scroll, window, render in 3D.
k-space explorer
A working 2D Fourier transform. Mask k-space and see exactly what each region encodes.
Contrast playground
Slide TR, TE, TI and flip angle and re-weight a brain in real time.
3D scanner model
Orbit a cutaway MR system — main magnet, gradient and RF coils, patient table.
Safety screening
Walk the ACR four-zone model and an interactive implant-screening tool.
The curriculum
Seven pillars — from a single spin to a confident read.
Pillar I · MRI Imaging Science
From a single proton’s spin to the Fourier-encoded raw signal: nuclear physics, relaxation, k-space, pulse sequences, contrast, hardware, artifacts and safety — the machinery beneath every image.
Pillar II · Cross-Sectional MRI Anatomy
The normal map on real volumes — brain, neurovascular tree, spine, musculoskeletal system and body — as the substrate every interpretation is measured against.
Pillar III · MRI Pathophysiology
How disease writes itself into signal: the biophysics of diffusion, the chemistry of evolving hemorrhage, the mechanisms of edema, tumor biology and ischemia.
Pillar IV · Organ-Based MRI Interpretation
Expert reading, organ by organ — brain, spine, musculoskeletal, cardiac, liver, pancreas and pelvis — from finding to differential to management.
Pillar V · Advanced MRI Modalities
Diffusion and tractography, perfusion, BOLD function, spectroscopy, cardiac mapping and quantitative MRI — imaging microstructure, hemodynamics, metabolism and function.
Pillar VI · Advanced Diagnostic Reasoning
Pattern recognition, Bayesian differential prioritization, error and cognitive bias, evidence-based imaging and the role of artificial intelligence.
Pillar VII · Integrated MRI Medicine
The synthesis: protocol design and structured, multi-sequence case interpretation that turns images into a biophysical measurement of tissue state.
It’s free. It always will be.
No account, no paywall, no tracking — just a warm welcome to anyone learning to read or run an MR scanner.
