Abstract: A method of imaging nervous tissue, comprising acquiring functional imaging modality data from a functional imaging modality which images an intrabody volume of a patient having a body part, the patient having been injected with an imaging agent having a nervous tissue uptake by an autonomic nervous system (ANS); and locating the nervous tissue in the intrabody volume based on the functional imaging modality data.

Abstract: A method of guiding a cardiac treatment using a functional imaging modality, comprising: providing functional imaging modality data from a functional imaging modality which images an intrabody volume of a patient containing a heart, the patient having been injected with an imaging agent having a nervous tissue uptake by an autonomic nervous system (ANS) of the heart, the ANS comprising at least one GP; locating the at least one GP innervating the heart based on the functional imaging modality data; and providing the located at least one GP.

Abstract: A method of medical image processing for images of body structures, comprising: receiving anatomical data to reconstruct an anatomical image of a region of a body of a patient, said region comprises a portion of at least one internal body part which borders or is spaced apart from a target tissue; receiving functional data from a functional imaging modality which images at least said portion of the region of the body of the patient; processing said anatomical image to generate at least one image mask corresponding to the zone outside of the wall of said at least one internal body part; correlating the at least one generated image mask with the functional data for guiding a reconstruction of a functional image depicting said target tissue; and providing the reconstructed functional image.
