Presenters will review methods used to decrease the dose of head CTs used to follow traumatic brain injury by decreasing the kV and mAs and using iterative reconstruction to decrease noise and artifact; demonstrate that there is no significant difference in the diagnostic quality of the lower dose head CTs with filtered-back projected or iterative reconstructed images; and review additional traditional methods of reducing dose to radiosensitive organs such as the eyes and thyroid gland.

Gastrointestinal Radiology

RC509-03 (Educational Course)

Oral Contrast Media Concentration Selection for Low kVp/keV CT Scanning
Wednesday, Dec. 2, 9-9:10 a.m.
Room 350

Oral contrast media (OCM) is commonly used for abdominal CT. Clinical implementation of low-kVp/dual energy CT (DECT) imaging demands adjustments in OCM concentration. In this session, presenters research the impact of low X-ray energy (kVp/keV) on OCM using phantom and clinical data and to assess optimal OCM concentrations for low-energy diagnostic CT scans.

Genitourinary Radiology

SPSC44 (Educational Course)

Controversy Session: Prostate Imaging: Just What MR Technique is Best?
Wednesday, Dec. 2, 4:30-6:00 p.m.
Room E450A

Presenters will review techniques that comprise high-quality multi-parametric MRI (mpMRI) of the prostate. More specifically, they will explore the key protocol questions necessary to set up mpMRI in a radiology practice. After an introduction and overview of mpMRI, sessions will cover:

  • 1.5T vs 3T Imaging: Pros and Cons
  • Diffusion Weighted Imaging
  • Dynamic Contrast-Enhanced Imaging
  • Imaging of Recurrence in Prostate Cancer

SPSH40 (Educational Course)

Hot Topic Session: Molecular Imaging and Radionuclide Therapy for Prostate Cancer Wednesday, Dec. 2, 7:15-8:15 a.m.
Room E451A

Radium-223 is a recently approved therapy for treatment of bone metastases in patients with metastatic prostate carcinoma. In this session, researchers present findings on:

  • Ra-223 Therapy for Skeletal Metastases from Prostate Cancer
  • Comparison of Ga-68 and F-18 Labeled Small Molecule PSMA Tracers for Prostate Cancer Imaging

Default Mode Network Structural-functional Connectivity and Beta-Amyloid Pathology in Autosomal Dominant Familial Alzheimer's Disease
Thursday, Dec. 3, 10:40-10:50 a.m.
Room N229

Early onset familial Alzheimer's disease (FAD) is inherited in an autosomal dominant manner and provides a model for studying how amyloid may affect disease onset and synaptic failure. Using data from Dominantly Inherited Alzheimer's disease Network (DIAN), presenters evaluate relationships between structural connectivity, functional connectivity and amyloid burden. This research received the RSNA Award for Trainee Research Prize—Resident.

Nuclear Medicine

SPNM61 (Educational Course)

Theranostics: Contributions of Diagnostic Nuclear Medicine and Targeted Radionuclide Therapy in Clinical Oncology (In Conjunction with SNMMI)

Friday, Dec. 4, 8:30-10 a.m.
Room S504AB

An important aspect of nuclear medicine and molecular imaging is that the same core compound of the administered radiopharmaceutical can be labeled with gamma emitters (for diagnostic) and beta (or alpha) emitters (for therapy), allowing for targeted treatment of lesions. This is an expression of theranostics—the combination of therapy and diagnostics that is based on the specific tumor biology of each patient's disease. Held in conjunction with the Society of Nuclear Medicine and Molecular Imaging (SNMMI), these sessions will offer several examples of such paired diagnostic studies and treatments using nuclear medicine methods:

  • Radioactive Iodine and Thyroid Cancer—Current Use and Controversies
  • Bone Scintigraphy and the Use of Radionuclides in the Management of Patients with Metastatic Castrate-Resistant Prostate Cancer
  • Updates on the Use of PET/CT (and PET/MRI) and Radioimmunotherapy in Non-Hodgkin's Lymphona
  • Peptide Receptor Radionuclide Imaging and Therapy: Where Are We in Europe and What Shall the U.S. Do to Catch Up?
  • Selective Internal Radiation Therapy for Hepatic Malignant Lesions

Radiation Oncology

RO262-SD-THB2 (Scientific Poster Discussion)

Glucosamine Augments
Sensitivity of Cancer Cells to Radiation
Thursday, Dec. 3, 12:45-1:15 p.m.
Radiation Oncology (RO) Community, Learning Center

Glucosamine, a supplement commonly used for the treatment of osteoarthritis, has been shown to decrease the incidence of adenocarcinoma of the lung and colon, and has also shown to be toxic to cancer cells in vitro at concentrations attainable in humans. Researchers explore the potential of using the nutritional supplement to enhance cancer treatment and investigate whether it is safe for patients to take this supplement while receiving radiation therapy.

Subspecialty content brochures will be available in the Grand Concourse Lobby, Level 3; Lakeside Center, Level 3 and Learning Center.

Question of the Day:

I want to change the MR imaging parameters for a new protocol based on a research paper I read, but the console says the SAR is too high. What is SAR?

Tip of the day:

Patients who have many follow-up head CTs should be assessed for dose to the eyes as they swiftly become at risk for cataracts.
