Section of Nuclear Radiology

Section of Nuclear RadiologyThe UTHSCSA section of Nuclear Medicine provides imaging services for San Antonio’s University Hospital and UT Medicine Systems.  Our team is comprised of 4 board certified physicians that have achieved subspecialized training through dedicated nuclear medicine residencies and fellowships. Our section delivers comprehensive Nuclear Medicine services with cutting edge techniques, some of which include:

 

Advanced Nuclear Medicine Techniques Provided:

  • Osteomyelitis Imaging with Hybrid Modality: utilizing single photon emission computed tomography (SPECT)/x-ray computed tomography (CT) for 3-D imaging:
    • Bone scan with multiphase SPECT/CT imaging.
    • White blood cell (WBC) infection imaging with simultaneous acquisition of radiolabeled WBC and bone marrow agent with SPECT subtraction.
  • PET/CT Imaging: for detection of malignancy, initial staging, response to therapy and restaging of disease to include lymphoma (Hodgkin’s and non-Hodgkin’s lymphoma), lung, breast, ovarian, cervical, uterine, esophageal, and colon cancer, and many others.
  • Myocardial SPECT Perfusion Imaging: for diagnosis of myocardial ischemia and infarction via stress and rest and as needed viability imaging and a gated acquisition for the determination of left ventricular ejection fraction.
  • Dopamine Transporter Imaging (DaTscan): for the diagnosis of Parkinson’s disease.
  • Brain Perfusion SPECT Imaging: for intractable seizure localization with interictal and ictal SPECT brain scans subtraction and MRI image co-registration.
  • Comprehensive Nuclear Medicine Endocrine Collaboration and Clinic: for diagnostic evaluation and radiotherapy of hyperthyroidism and most thyroid cancers.
  • Radiotherapeutic Microspheres for the Treatment of Liver Cancer with SPECT/CT pre-therapy and post therapy imaging. Availability of two different Y-90 beta-emitting microspheres, Y-90 SIR-spheres for a more embolic therapy and Y-90 Theraspheres for more specific radiation therapy and segmentectomy.
  • Solid Gastric Emptying 4 hour study: utilizing the standardized radiolabeled egg meal, simultaneous blood glucose levels and patient symptoms to assess for delayed gastric emptying (gastroparesis) and rapid gastric emptying (functional dyspepsia). Availability of a standardized liquid carbohydrate glucose meal for assessment of carbohydrate gastric emptying.
  • Parathyroid Imaging using SPECT/CT Imaging with capability for Parathyroid 4D-CT Image Fusion: for the diagnosis of parathyroid adenomas and improved pre-surgical localization.
  • Extensive Research Capabilities in Clinical Nuclear Medicine: Current Phase I/II testing of a novel nanoparticle radionuclide therapy for the treatment of glioblastoma. This novel therapy has been developed in the UTHSCSA radiology research laboratories and its clinical testing is an example of a bench to bedside initiative.
