In an illustrative embodiment, the method com­ prises a steps of generating a first parametric map, generating second a para­ metric map, and then generating a masked parametric map that reflects para­ meters in the first and second parametric maps. The masked map may present information not readily apparent from the first parametric map and the second parametric map, and not obtainable from the first and second parametric maps independently. The first parametric map may be based upon portions of two optoacoustic images created using differing wavelengths of light. The first parametric map is reflective of areas within the volume of tis - sue that have a differing response to the longer wavelength light event com­ pared to the shorter one. The second parametric map is reflective of areas within the volume of tissue that have a stronger response to the longer and shorter wavelength light events than the surrounding areas. A masked para­ metric map is output which is reflective of combination of information a in the first and second parametric maps. In an embodiment, the masked para­ metric map is generated by generating a mask reflective of combination a of information in the first and second parametric maps, and applying the mask to one of the first or second parametric maps to form the masked parametric map. In an embodiment, one or more of the parametric maps is coregistered with, and overlayed on an ultrasound image of the same volume of tissue be­ fore being output.
