RT Journal Article SR Electronic T1 NETs (Neuroendocrine tumours) – A pictorial review JF Journal of Nuclear Medicine JO J Nucl Med FD Society of Nuclear Medicine SP 241534 OP 241534 VO 65 IS supplement 2 A1 G Ravindra, Shubha A1 Garg, Sumit A1 Khurana, Aditi A1 Kumar, Rakesh A1 Bal, Chandrasekhar YR 2024 UL http://jnm.snmjournals.org/content/65/supplement_2/241534.abstract AB 241534 Introduction: Some of the commonly encountered NETs include – GEP NETs, bronchial NETs, neuroblastoma, pheochromocytoma, paraganglioma and medullary carcinoma thyroid. The radiotracers, characteristic locations of occurrence, imaging features and role of nuclear medicine imaging in these tumours will be described in this exhibit.Methods: Some of the radiotracers discussed will include MIBG, SSTR agonists and DOPA with their relative advantages and disadvantages. A pictorial review of cases of NET – medullary carcinoma thyroid, bronchial carcinoid, GEP NET(WHO classification and grading; non-functional and functional – insulinoma, gastrinoma), neuroblastoma(various locations), pheochromocytoma, paraganglioma (various locations – head and neck (glomus tympanicum, glomus jugulare, glomus vagale, carotid body tumour; chest; abdominal) highlighting of role of nuclear imaging in various clinical scenarios will be provided including diagnosis, staging, response assessment, recurrence and therapy planning (assessment of tumour grade) including diagnostic pearls and pitfalls.Results: The exhibit will be described under following headings – Radiotracers and their physiologic distribution; Case Scenarios using these radiotracers highlighting location, imaging features and specific role and Pearls and pitfalls.Conclusions: In this exhibit, we present cases that highlight the role of nuclear imaging in various NETs.
