Discordant Core Needle Biopsies: A Predictive Model that Identifies Low Probability Lesions to Safely Avoid Surgical Excision

Tuesday 12:15-12:45 PM | BRS-TUA | Learning Center, Hall D
Mai A. Elezaby, M.D., | Finn Kuusisto | Jude Shavlik, PhD | Yirong Wu, Ph.D., | Ines Dutra, PhD | Elizabeth S. Burnside, M.D., M.P.H., | Heather Neuman, | Wendy B. Demartini, M.D.

Led by presenter Mai Elazaby, this Madison-based research team created a model that could reduce surgical excision when dealing with possibly malignant breast tumors. The model determines the probability of malignancy using patient risk factors, imaging descriptors and assessment categories, and information from the core needle biopsy.

Relationship between Computer-extracted MRI-based Phenotypes and the Risk of Breast Cancer Recurrence as Predicted by PAM50 Gene Expression Array

Tuesday 3:00-4:00 PM | SSJ01 | Arie Crown Theater
Elizabeth S. Burnside, M.D., M.P.H., | Hui Li | Charles Perou, PhD | Karen Drukker, PhD | Elizabeth A. Morris, MD | Maryellen L. Giger, PhD | Ermelinda Bonaccio, MD | Margarita L. Zuley, MD | Marie A. Ganott, MD | Jose M. Net, MD | Elizabeth J. Sutton, MD | Kathleen R. Brandt, MD | Gary J. Whitman, MD | Suzanne Conzen, MD | Li Lan, | Yitan Zhu, PhD | Yuan Ji, | Erich Huang, PhD | John B. Freymann, BS | Justin Kirby, | C. Carl Jaffe, MD

Elizabeth Burnside is presenting the efforts of a nation-wide research team to investigate the relationship between breast MRI and genetic profiles, in order to assess the risk of breast cancer recurrence. The group used quantitative breast MRI and the PAM50 gene array, which measures the risk of relapse. Their model, called “Computer Extracted Image Based Tumor Phenotype,” preformed imaging analysis, and the model showed statistically significant correlation with the risk predicted from the gene array.

A Practical Approach for Beginning Radio-genomic Research

Tuesday 4:30-6:00 PM | RC454 | S501ABC
Elizabeth S. Burnside, M.D., M.P.H.

This educational session features Elizabeth Burnside along with several Chicago-area speakers. The learning objectives for the session include: planning and online resources required to create a successful radio-genomic research team, what skill-sets are needed in team members, and how to grasp the unfamiliar research framework of a radio-genomics project.

CT and MR of Acute Appendicitis

Tuesday 8:30-8:55 AM | RC30801 | N228
Perry Pickhardt, M.D.

Perry Pickhardt, recognized as an RSNA Honored Educator, will lecture on the relative advantages and disadvantages of CT or MR imaging in the case of suspected appendicitis. In addition, he will compare the diagnostic performance of both modalities, as well as describe the increasing use of MR for abdominal imaging in an emergency department setting.

Extracolonic Findings at Screening CT Colonography: Analysis of Incompletely Characterized and Likely Insignificant (C-RADS E3) Findings

Wednesday 10:30-12:00 PM | SSK06 | E351
Bryan D. Pooler, M.D. | David H. Kim, M.D. | Perry J. Pickhardt, M.D.

3rd-year resident B. Dustin Pooler will present a study investigating the incidence and outcomes of extracolonic findings at CT colonoscopies. Extracolonic findings are uncommon, occurring in less than 10% of patients. Even fewer patients (>1%) were diagnosed with conditions requiring treatment or continued imaging, leading the authors to conclude that extracolonic malignancies are rare.

Assessment of Congenital Heart Disease with 4D Flow

Wednesday 3:00-4:00 PM | SPSH53 | S402AB
Christopher J. Francois, M.D.

Dr. Francois will give an overview of how 4D Flow MRI can be used throughout the treatment of congenital heart disease, summarizing published data validating flow quantification and distribution in the condition. In addition, Francois will touch on future directions for both 4D Flow MRI and the treatment of congenital heart disease.

When Less is More: Exploiting Vessel Sparsity to improve 4D CEMRA of Dural AV Fistulas

Thursday 8:30 AM | NR134 | ED-X
Zachary Clark, M.D., M.S. | Kevin M. Johnson, | Yijing Wu, | Myriam Edjlali, | Oliver Wieben, Ph.D. | Patrick A. Turski, M.D.

The purpose of this exhibit is to review the classification and imaging characteristics of dural arteriovenous fistulas (dAVF). It will illustrate how vessel sparsity makes 4D contrast enhanced MRA a viable option, and how to specifically use 4D contrast MRA for dAVF classification.
