1. A method of guiding a cardiac treatment using a functional imaging modality, comprising:
- providing functional imaging modality data from a nuclear medicine imaging modality which images an intrabody volume of a patient containing a heart, the patient having been injected with a radioactive imaging agent having a nervous tissue uptake by an autonomic nervous system (ANS) of the heart, the ANS comprising at least one ganglionic plexus (GP);
receiving at least one image mask corresponding to location of a fat pad at a predefined anatomical region identified on an anatomical image acquired by an anatomical imaging modality, wherein said at least one GP is not identifiable on said anatomical image;
applying the at least one image mask to the functional imaging modality data to the location corresponding to the fat pad at the predefined anatomical region;
locating the at least one GP innervating the heart within the at least one image mask applied on the functional imaging modality data, by differentiating the at least one GP from the fat padbased on at least one predefined rule, said rule relying on a calculated activity of a radio labeled tracer within a spot in said respective image mask being indicative of the at least one GP, said activity being larger than activity of an area surrounding the spot within the respective image mask indicative of the fat pad, by more than a predefined threshold; and
guiding an ablation cardiac treatment to the located at least one GP within the fat pad for treating cardiac disease.

13. A system for identifying ANS tissue within an image of a heart of a patient and providing cardiac treatment, the system comprising:
-
a non-transitory computer readable medium storing program instructions; at least one hardware processor in communication with said non-transitory computer readable medium, that when said instructions are executed by said at least one hardware processor, the execution causes said at least one hardware processor to; receive functional imaging modality data from a nuclear medicine imaging modality which images an intrabody volume of a patient containing a heart, the patient having been injected with a radioactive imaging agent having a nervous tissue uptake by an autonomic nervous system (ANS) of the heart, the ANS comprising at least one ganglionic plexus (GP); receive anatomical imaging modality data from an anatomical imaging modality which images an intrabody volume of a patient containing the heart; receive at least one image mask corresponding to location of a fat pad at a predefined anatomical region identified on an anatomical image reconstructed from said anatomical imaging modality data, wherein said at least one GP is not identifiable on said anatomical image; apply the at least one image mask to the functional imaging modality data to the location corresponding to the fat pad at the predefined anatomical region; locate the at least one GP innervating the heart within the at least one image mask applied on the functional imaging modality data, by differentiating the at least one GP from the fat pad based on at least one predefined rule, said rule relying on a calculated activity of a radio labeled tracer within a spot in said respective image mask being indicative of the at least one GP, said activity being larger than activity of an area surrounding the spot within the respective image mask indicative of the fat pad, by more than a predefined threshold; position the located at least one GP within the fat pad on the anatomical imaging data; and generate and output to display a combined image from said anatomical imaging modality data and said functional imaging modality data of the positioned at least one GP. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A system for identifying ANS components within an image of a heart of a patient and providing cardiac treatment, the system comprising:
-
a non-transitory computer readable medium storing program instructions; at least one hardware processor in communication with said non-transitory computer readable medium, that when said instructions are executed by said at least one hardware processor, the execution causes said at least one hardware processor to; receive functional imaging modality data from a nuclear medicine imaging modality which images an intrabody volume of a patient containing a heart, the patient having been injected with a radioactive imaging agent having a nervous tissue uptake by an autonomic nervous system (ANS) of the heart, the ANS comprising at least one GP comprising one or more of;
superior left GP (SLGP), inferior left GP (ILGP), anterior right GP (ARGP), inferior right GP (IRGP), and Marshall GP;receive anatomical imaging modality data from an anatomical imaging modality which images an intrabody volume of a patient containing the heart; receive at least one image mask corresponding to location of a fat pad at a predefined anatomical region identified on an anatomical image reconstructed from said anatomical imaging modality data, wherein said at least one GP is not identifiable on said anatomical image; apply the at least one image mask to the functional imaging modality data to the location corresponding to the fat pad at the predefined anatomical region; locate the at least one GP in the intrabody volume of the heart within the at least one image mask applied on the functional imaging modality data and anatomical imaging modality data, by differentiating the at least one GP from the fat pad based on at least one predefined rule relying on calculated activity of a radio labeled tracer within an activity spot above a predefined threshold in comparison to surrounding activity within the at least one image mask being indicative of the at least one GP, said activity being; and generate and output to display a combined image from said anatomical imaging modality data and said functional imaging modality data of the positioned at least one GP within a fat pad. - View Dependent Claims (27, 28)
