Oncology Imaging

The Oncology Imaging Program at UT Southwestern Medical Center is dedicated to studying and treating cancer through the use of innovative imaging and proven effective methodologies.


UT Southwestern is at the forefront of using positron emission tomography (PET) to identify whether a patient has cancer, whether the cancer is spreading or responding to treatment, and whether the patient has gone into remission after treatment. PET scanning is particularly effective for a variety of cancers, including lymphoma, melanoma, brain, breast, head and neck, lung, gastrointestinal, and gynecological cancer.


Our radiology service offers various procedures for diagnosing as well as treating cancers. We are one of only two facilities in Dallas to offer Selective Internal Radiation Therapy (SIR-Spheres), a radioembolization procedure for liver cancer. SIR-Spheres uses microscopic beads containing radioactive material that are injected through a catheter to target liver tumors.

We also offer palliative treatments for painful bone cancer metastases, and targeted “salvage therapy” treatments for non-Hodgkins lymphoma. Radioactive iodine (I-131) is a well-established and effective option that our specialists use to treat thyroid cancer.
