Structural MRI yields noninvasive, high-resolution pictures of brain anatomy and structure. It uses strong magnetic fields and radiofrequency pulses to create detailed cross-sectional images that clearly differentiate gray matter, white matter, and cerebrospinal fluid, making it ideal for mapping brain morphology and spotting structural abnormalities. The other options are histological stains applied to fixed tissue to reveal cellular details or myelin after tissue processing (Golgi for neuron morphology, Nissl for cell bodies, Weigert for myelin). While they provide rich cellular or fiber information, they require tissue preparation and aren’t imaging the intact brain in vivo.
