Imaging Pathway of a Pediatric Patient with Succinate Dehydrogenase B-Deficient Paraganglioma.

Pheochromocytoma and paraganglioma are rare in children, at only 1 in every 50,000 cases. Even though some cases are sporadic, they have been connected to syndromes such as von Hippel-Lindau, multiple endocrine neoplasia types IIa and IIb, neurofibromatosis type 1, and hereditary pheochromocytoma-paraganglioma syndromes. A genetic mutation causes around 60% of pheochromocytomas and paragangliomas in children under 18.

Stability Matters: Radiochemical Stability of Therapeutic Radiopharmaceutical Lu-PSMA I&T.

Labeling radiopharmaceuticals and testing the quality of the labeled product before injecting it into patients are standard operating procedures in the nuclear medicine department. There is a different shelf life for each labeled product, which determines how long a product can maintain in vitro stability before it needs to be discarded. Lu is a radioactive isotope that is increasingly being accepted into the treatment paradigm for palliation of advanced-stage tumors, including metastatic castration-resistant prostate cancer (mCRPC) and neuroendocrine tumors (NETs).

Lutetium DOTATATE whole body scans: A novel approach for evaluation of neuroendocrine tumors.

Aim: We undertook a study to evaluate whether Lutetium (Lu) DOTATATE whole body scan is well comparable to Gallium positron emission tomography (PET) / Indium Octreotide, and hence with dosimetric advantage can replace it in the pre-therapy setting.

Materials And Methods: We undertook a prospective study of a total of 39 patients with metastatic neuroendocrine tumor (age 11-70 years), who underwent Lu-DOTATATE scans within the period August 2009-November 2010. This included 28 males and 11 females.
