What is Southern Isotopes

Southern Isotopes provides clinical Positron Emission Tomography (PET) radiopharmaceutical products to PET imaging centers in Louisiana, Mississippi, Arkansas, Alabama, and Texas. With manufacturing facilities in Shreveport and Baton Rouge, products such as FDG and sodium fluoride (NaF) can be distributed easily and efficiently.

SI is engages in radiochemistry and imaging research and has access to clinical imaging resources. Our research laboratories in Shreveport supply research products and services while imaging support services are available through BRF’s PET Imaging Center in Shreveport.

Our Services and Products

SI staff specializes in optimization, production and distribution of 18F chemical compounds ranging from the routine (e.g. 18F-FDG) and public domain (e.g. 18F-F-Dopa and 18F-FLT) to proprietary experimental compounds in all phases of clinical trials (FDA eIND, Phase I, II, and III). We have significant experience producing labeled PET and SPECT compounds with other isotopes including 13N, which is produced in house, or 64Cu, 76Br, 99Tc, 123I, 124I, 125I, 131I, 111In, 51Cr, 67Ga, 153Sm, 89Sr, 201Tl, and 133Xe, which can be accessed from partner facilities.

Our Partners and Customers

SI facilities are located on and near the LSU Health Shreveport campus, providing access to critical clinical and research resources for client projects.

The Virginia K. Shehee Biomedical Research Institute (BRI) is a 10-story, 160,000 square foot research facility with 56 wet labs occupied by LSU Health Shreveport researchers. BRI facilities contain core research equipment for high performance liquid chromatography (HPLC), flow cytometry, automated cell sorting, tissue culture, magnetic resonance spectroscopy, fluorescence, confocal and electron microscopy, real time PCR, mass spectroscopy, and DNA Gene chip analysis.

LSU Health Shreveport Small Animal Research Facility is an AALAC accredited Animal Research Facility (ARF) which provides key support for pre-clinical studies. Veterinary care professionals offer guidance and assessment regarding all animal use protocols, maintenance of transgenic mouse breeding colonies, routine and diagnostic animal colony health surveillance and environmental monitoring programs. Consultation and training in specialized procedures are available. This primary and a nearby animal facility supports mice, rats, rabbits, guinea pigs, swine, and goats.

LSU Health Shreveport Small Animal Imaging Facility is an animal imaging facility that contains state-of-the-art equipment for in vitro and in vivo CT, PET, SPECT and bioluminescence/ fluorescence imaging. The recently installed Flex Triumph system (GammaMedica-Ideas, Northridge, CA) is a first of its kind tri-modality imaging system (PET/SPECT/ CT) for rodents. This system, with a full suite of life signs monitoring/support components (heart, breathing, temperature, anesthesia, blood micro-sampling) is an excellent resource for extended imaging protocols, as might be required for pharmacokinetic modeling.

Our Staff

A highly qualified SI staff of 13 specialists includes radiochemists, radiopharmacists, cyclotron operators and engineers, radiopharmaceutical production personnel, and administrative support personnel.

Additional personnel resources that collaborate and support SI through the parent company, Biomedical Research Foundation, include physicists, physicians, CNMTs, and administrative support personnel.

BRF’s PET Imaging Center

BRF’s PET Imaging Center provides unparalleled diagnostic and clinical research expertise, having performed over 35,000 PET scans in the last 15 years. Our two PET/CT scanners currently average 40 scans per week, resulting in a vast image database of common and rare diseases. Scans are read by dedicated, board certified, nuclear medicine physicians. PETIC is accredited by the European Intersocietal Commission for the Accreditation of Nuclear Medicine Laboratories (ICANL).
