Modern nuclear imaging for paragangliomas: beyond SPECT.

Area of Science:

• Oncology
• Nuclear Medicine
• Radiology

Background:

• Paragangliomas are rare neuroendocrine tumors with frequent hereditary or multifocal forms.
• While often benign, about 10% of paragangliomas can metastasize, necessitating comprehensive imaging.
• Nuclear and anatomic imaging are crucial for disease extent delineation.

Purpose of the Study:

• To provide an overview of available and emerging PET tracers for paraganglioma imaging.
• To guide clinicians in selecting appropriate PET tracers based on tumor localization and genetic status.
• To enhance understanding of imaging phenotypes and molecular genetics for nuclear medicine physicians.

Main Methods:

• Review of current literature on PET tracers for paraganglioma.
• Analysis of tracer utility in relation to tumor characteristics and genetic profiles.
• Discussion of novel PET radiotracers under research.

Main Results:

• PET imaging is increasingly utilized for paraganglioma, with ongoing development of new tracers.
• Tracer selection for PET imaging should be personalized based on tumor site and patient's genetic status.
• Understanding the link between imaging phenotypes and molecular genetics is key.

Conclusions:

• Personalized selection of PET tracers is essential for effective paraganglioma management.
• Continued research into novel PET tracers will improve diagnostic accuracy.
• This review aids clinicians in optimizing imaging strategies for paraganglioma patients.
