MR Microscopy
The current method of choice for highly-resolved morphological characterization of the human tissue remains histology. If spatial resolution, contrast and sensitivity are sufficient, MR microscopy can be used as a powerful instrument for in vivo investigation as an alternative to invasive histopathological sampling.
