Instructional Design Capstones Collection
The radiologic technology field is rapidly changing. Its technologists and students need to be prepared for these alterations. All students and technologists must pass the national board exam administered by the American registry of Radiologic Technologist. This exam assesses the participant in patient care, image acquisition, radiation safety and imaging procedures. The performance problem identified is the increased amount of radiologic technologists and radiologic technology students either failing the registry due to being unprepared, or due to insufficient continuing education credits. Many of these technologists have been out of the classroom for 20 years, seemed adapted to their own imaging ...

Case Report: Elbow Plica In A High School Pitcher, Steven Barrientos Do, Sunny Gupta Do, Mitesh Patel Md
Stratford Campus Research Day
Elbow pain is a very common joint complaint with a variety of etiologies. Plica are often benign, asymptomatic and have no known function. Elbow plica may cause clinical symptoms in the elbow joint after they become hypertrophied or inflamed from repetitive activities or trauma. Symptomatic elbow plica may strike at any age but it is not a common radiographic finding among the pediatric population. In this case report, we are presenting a case of symptomatic left lateral hypertrophic elbow radiocapitellar plica in a 16 year old baseball thrower.

Old Dog With New Tricks: 99mtc-Sestamibi Spect-Ct For Renal Mass Differentiation, Zachary Beswick, Ishani Dalal
Teaching and Education
Small renal masses have historically presented a diagnostic challenge for radiologists and urologists. MRI and CT have a limited capability to differentiate benign and malignant small solid renal masses. The relatively poor negative predictive value of renal biopsy limits the ability to avoid surgical resection in small renal masses with negative biopsy. 99mTc-sestamibi SPECT-CT can be an important tool in directing the management of patients with renal masses.We present the analysis of 99mTc-sestamibi uptake patterns in patients with small renal masses who underwent further characterization of these masses with 99mTc-sestamibi SPECT-CT. Pertinent interpretation points in differentiating renal cell carcinoma ...

Creative Activity and Research Day - CARD
Deep learning algorithms have become widely popular, with considerable success in fields where datasets have hundreds of thousands or million points. As deep learning is increasingly applied to the fields of medical physics and radiation oncology, a reasonable question follows: are these techniques the best approach, given the unique conditions in our field? In this study, we investigate the dependence of dataset size on the performance of deep learning algorithms compared with more traditional radiomics-based methods.

Despite aggressive peri-operative antibiotic treatments, up to 10% of patients undergoing instrumented spinal surgery develop an infection. Like most implant-associated infections, spinal infections persist through colonization and biofilm formation on spinal instrumentation, which can include metal screws and rods for fixation and an intervertebral cage commonly comprised of polyether ether ketone (PEEK). We have designed a PEEK antibiotic reservoir that would clip to the metal fixation rod and that would achieve slow antibiotic release over several days, followed by a bolus release of antibiotics triggered by ultrasound (US) rupture of a reservoir membrane. We have found using human physiological fluid ...
Parallel Transjugular Intrahepatic Portosystemic Shunt With Viatorr® Stents For Primary Tips Insufficiency: Case Series And Review Of Literature, Driss Raissi, Qian Yu, Michael Nisiewicz, Steven Krohmer
Radiology Faculty Publications
Transjugular intrahepatic portosystemic shunts (TIPS) can alleviate complications of portal hypertension such as ascites and variceal bleeding by decreasing the portosystemic gradient. In limited clinical situations, parallel TIPS may be only solution to alleviate either variceal bleeding or ascites secondary to portal hypertension when the primary TIPS fails to do so. Data specifically addressing the use of this partially polytetrafluoroethylene covered nitinol stent (Viatorr®) is largely lacking despite Viatorr® being the current gold standard for modern TIPS placement.
All three patients had portal hypertension and already had a primary Viatorr® TIPS placed previously. All patients have undergone ...
