Abstract
The invention relates to a diagnosis apparatus for simultaneously collecting information on tissue structure and tissue quality from a target, e.g. human body to be examined. The apparatus of the invention comprises means (1) for emitting ultrasonic pulses and for detecting and registering reflections from the interfaces between tissues in target area (16) determined by said means, and means (10) for processing the information obtained from a target area by means of said ultrasonic pulses as well as means (8) for visualizing the information for finding and localizing tissue area to be characterized. The apparatus is further provided with elements (2, 3, 11, 12, 13) for collecting tissue identification information by means of a nuclear magnetic resonance or NMR-phenomenon from target to be examined in manner that the tissue identification area (19) sensitive to nuclear magnetic resonanse is arranged to be produced in said target area (16) localized and visualized by ultrasonic pulses for immediate analysis on said tissue area to be characterized.
