Nuclear Medicine (PET/CT) Scans

Houston Methodist offers imaging services that use state-of-the-art nuclear (PET/CT) scans. This hybrid technology merges two diagnostic studies into a single exam, allowing physicians to see tumor anatomy and function simultaneously. Providing diagnosis, management, treatment and prevention of diseases is a priority for Houston Methodist and our expert radiologists.

Types of Nuclear Medicine (PET/CT) Scans 
Below is a list of nuclear medicine (PET/CT) scans that are performed at Houston Methodist’s convenient locations in the Greater Houston area:

  • I-131 whole body scans evaluate thyroid metastasis in patients who have had thyroidectomies or known thyroid tumors.
  • Bone scans evaluate degenerative or arthritic changes in the joints, detect bone diseases and tumors, and determine the cause of bone pain or inflammation.
  • Bone density is measured using a dual energy X-ray absorptiometry (DEXA) scanner .
  • Brain scans investigate problems within the brain or in the blood circulation to the brain.
  • Breast scans locate cancerous tissue in the breast that may have been detected during a mammogram.
  • Gallium scans diagnose active infectious or inflammatory diseases, tumors and abscesses.
  • Heart scans identify abnormal blood flow to the heart, determine the extent of damage to the heart muscle after a heart attack and measure heart function.
  • Hepatobiliary scans diagnosis acute cholecystitis and biliary tract obstruction, and evaluate gallbladder function, postsurgical biliary tract and bile leaks.
  • Lung ventilation and perfusion scans (VQ scans) diagnose pulmonary embolism and perfusion and ventilation post lung transplant.
  • Lymphoscintigraphy identifies and localize draining lymph node groups and sentinel nodes in breast cancer and melanoma.
  • Octreoscans detect and localize neuroendocrine tumors, including carcinoid tumors, paraganglimoas, gastrinomas, pheochromocytomas, neuroblastomas, glucagonomas  and functioning and non-functioning anterior pituitary tumors.
  • Parathyroid scans detect and localize parathyroid adenomas in patients with primary hyperparathyroidism prior to surgery.
  • Renal scans examine the kidneys and detect any abnormalities, such as tumors or obstruction of the renal blood flow.
  • SPECT scans evaluate a 3-D view of any organ for further clarification of a particular condition or disease.
  • Thyroid scans evaluate thyroid function.
