• Abstract: Magnetic resonance imaging (MRI) is a foundational tool in the physical and life sciences, yet conventional implementations are typically limited to macroscopic spatial resolution. Here, we introduce a method for nanoscale MRI by combining strong, time-dependent magnetic field gradients with global coherent control over a dense ensemble of electron spins in diamond. This approach enables spatially structured manipulation of spin dynamics, allowing us to generate and track nanoscale spin textures - patterns of spin polarization - that evolve under engineered many-body dipolar interactions. By tuning the rotational symmetry of the dipolar exchange interactions, we observe pronounced sensitivity of the spin dynamics to the microscopic structure of the polarization, which we resolve through nanoscale MRI. Our results open the door for robust control of metrologically useful entanglement and nanoscale imaging of materials and biological systems under ambient conditions.
