More to See at RSNA 2013: Sessions in Every Subspecialty

Here's just a sampling of what RSNA attendees can learn in refresher courses and scientific and education presentations in every subspecialty. View scientific posters and education exhibits in the Lakeside Learning Center through Friday. Virtual meeting registrants may also view posters and exhibits by logging in from outside McCormick Place.

BIOMARKERS/QUANTITATIVE IMAGING

MR Quantification Techniques in the Liver (Fat, Iron, Fibrosis)
Hot Topic Session SPSH52
Thursday, Dec. 5 • 3:00–4:00 p.m.
Room E350

Radiologists play a critical role in MR quantification techniques in the liver. Understanding the relative accuracy and performance of ultrasound, CT and MR imaging for the detection and quantification of hepatic steatosis is critical. This session covers the fundamentals of emerging confound-corrected MR imaging methods to quantify liver fat content; the need for non-invasive assessment of liver iron as well as qualitative and quantitative methods with a particular emphasis on MR imaging; and MR-based techniques to evaluate liver fibrosis including the fundamentals of MR elastography.

CHEST

Fluorine-19 MRI: A New Functional Pulmonary Imaging Modality
Part of Scientific Paper Session SSG04—Chest (Functional Lung/Perfusion)
Tuesday, Dec. 3 • 10:30 a.m.–12:00 p.m.
Room S404CD

Inert fluorinated gases are nontoxic, abundant, inexpensive and have short longitudinal relaxation times. In addition, the gases provide sufficient thermally polarized signal for imaging and don't have to be hyperpolarized before use in MR imaging. Researchers sought to optimize fluorine-19 MR imaging acquisition strategies and breathing protocols for imaging human lungs. They determined this new pulmonary imaging modality can efficiently and inexpensively obtain high-quality images of the lung and can potentially be used on patients with chronic lung disease.

MUSCULOSKELETAL

Four-year Experience Follow-up in the Treatment of Degenerative Disease of the Supraspinatus Tendon by Ultrasound guided Injections of PRP. Clinical and Radiological Evidence
Scientific Poster LL-MKS-TH3A

Using ultrasound and MR imaging, researchers evaluated the role ultrasound-guided platelet rich plasma (PRP) treatment plays in tendinopathy of the supraspinatus tendon of the shoulder compared to physiotherapy. In the study, 116 patients underwent three ultrasound-guided PRP treatments 21 days apart, while 82 underwent physiotherapy. Researchers determined that PRP provided patients with "considerable results" in terms of symptomatology and functionality and may reduce proneness to tendon tear.

NEURORADIOLOGY

Effect of Insurance Status on Imaging Utilization for Acute Ischemic Stroke
Part of Scientific Paper Session SST10—Neuroradiology (Cerebral Ischemia, Hemorrhage and Vessel Wall Imaging)
Friday, Dec. 6 • 10:30 a.m.–Noon
Room N227

Researchers studied a large nationwide database to determine if insurance-based disparities exist in the utilization of imaging for acute ischemic stroke. Researchers stratified patients into four groups according to insurance status—uninsured, Medicaid, Medicare and private insurance—and compared utilization rates of head CT, CT perfusion, head MR imaging, non-invasive head angiography, non-invasive neck angiography, carotid ultrasound, and echocardiography using a chi-squared test. Investigators discovered significant disparities in the utilization of neuroimaging for acute ischemic stroke based on patient insurance status as well as significant insurance-based disparities in the utilization of advanced imaging for acute ischemic stroke.

Quantitative DTI for Prediction of Neurocognitive Outcome in Severe Traumatic Brain Injury: A Five-year Prospective Cohort

Diffusion Tensor Imaging and Neuropsychological Performance in Post-acute Blast-induced Traumatic Brain Injury among U.S. Military Veterans
Part of Scientific Paper Session SSC12—Neuroradiology/Head and Neck (Traumatic Brain Injury)
Monday, Dec. 2 • 10:30 a.m.–Noon
Room N229

One study found that diffusion tensor imaging (DTI) is an accurate predictor of future disability levels in patients with severe traumatic brain injury (TBI). Researchers tracked changes in 16 TBI patients over a span of five years post-injury using quantitative DTI parameters. DTI changes in the corpus callosum, the bundle of fibers that connects the two halves of the brain, provided the best long-term prognostic value for severe TBI.

In another study, researchers performed DTI on10 veterans of Operations Iraqi Freedom and Enduring Freedom with blast-induced TBI and compared the DTI-derived fractional anisotropy (FA) values with those of healthy controls. The veterans had lower FA values, suggesting injury to the brain's white matter. The results indicate that DTI could help distinguish TBI from post-traumatic stress disorder (PTSD) in veterans.

PEDIATRIC RADIOLOGY

Child Abuse (an Interactive Session)
Refresher Course 513
Wednesday, Dec. 4 • 8:30–10:00 a.m.
Room S103AB

Radiologists play a critical role in raising concerns for injuries potentially related to child abuse. In this session, presenters will detail skeletal injury patterns associated with physical child abuse, discuss the mechanism of injury of inflicted injuries, the type and specificity of abusive injuries and review the difference in metabolic bone disease, skeletal dysplasias, accidental injuries and normal variants that can mimic abuse. Presenters will also review abusive head trauma and the imaging appearance of spinal injuries in children with abusive trauma and discuss imaging strategies for detection of spinal injury in children with non-accidental trauma and the role of MR imaging.

VASCULAR

Utilization of the iPad for Patient Education During Informed Consent in Interventional Radiology: A Randomized Controlled Trial
Part of Scientific Paper Session SST16—Vascular/Interventional (MR Guidance/Topics of Interest)
Friday, Dec. 6 • 10:30–Noon
Room E350

Researchers examined whether interactive media presented on an iPad improves patient understanding and confidence during the informed consent process in interventional radiology. Presenters found that the iPad is a useful tool to help build a patient-physician relationship before an interventional procedure and can be very helpful during informed consent for interventional radiology procedures. In addition, the iPad significantly increases patient understanding, confidence and satisfaction.
