We describe a method which exploits unaveraged dipolar effects from a specific set of tissue-to-B0 orientations to produce detailed, high contrast MR images in fibrocartilage. Minimum intensity and coefficient of variation (CV) maps allow visualization of fiber structures previously not appreciated using MRI. This technology is a reduced sampling version of the Dipolar Anisotropy Fiber Imaging (DAFI) technology we have recently introduced. An example of a human knee meniscus specimen is demonstrated.
