Radiology Research Day


2022 Radiology Research Day

Presentation of schedule at Research Day.

The sixth annual Johns Hopkins Radiology Research Day returned to form this year as in-person event after two years of virtual gatherings due to the COVID-19 pandemic. 

The event is the work of many dedicated faculty and staff members, including professor Zaver Bhujwalla,Ph.D., M.Sc. Bhujwalla’s titles include vice chair of research for the Department of Radiology and Radiological Science, director of the Division of Cancer Imaging Research, and co-leader of the Cancer Molecular and Functioning Imaging Program at the Sidney Kimmel Comprehensive Cancer Center.

Presentation of Resilience at Research Day.

Attendees gathered in The Johns Hopkins Hospital’s Turner Auditorium as Karen Horton, M.D., department chair, began the day with introductory remarks. Presentations by several radiology associate professors followed, including Nirbhay Yadav, Ph.D., who highlighted research on high resolution MRI imaging of cellular metabolism. 

Research related to COVID-19 was a consistent theme throughout the event, with associate professor Eniola Oluyemi, M.D., detailing research on COVID-19 vaccine-related axillary adenopathy in breast imaging, and later, assistant professor Caitlin Tressler, Ph.D., discussing her work applying MALDI imaging to COVID-19 cases. 

Presentation of a slide with background information at Research Day.

During the Special Award session for postdoctoral fellows, presentations offered a peek at cutting-edge imaging that looks at some of the most serious medical conditions in a new way. Saleem Yousf, Ph.D. offered an engaging presentation on photoacoustic imaging of in vivo blood oxygenation in organs of mice with a pancreatic cancer xenograft, and Yuto Uchida, Ph.D. presented research on brain imaging of patients with pre-clinical Alzheimer’s disease.

A special session of radiology resident presentations included remarks from Natalie Ring, M.D., who detailed the newly developed Patient-Reported Outcome Measure for Vascular Malformation Questionnaire for patients with low-flow vascular malformation, and Andrew Simmerman, M.D., who discussed imaging of rapidly progressive interstitial lung disease (RP-ILD). 

Presentation of a poster at Research Day.

After a busy morning, participants took a break for pizza. More than 60 posters detailing cutting edge research from across the radiology department lined the Turner Concourse outside of Tilghman Auditorium as judges strolled the room, selecting their top picks.

The afternoon began with a clinical imaging focus. Chris Bailey, M.D., walked attendees through the process of designing a novel IR device, while Craig Jones, Ph.D., M.S., addressed various AI applications in clinical radiology.

Research award winners Harrison Bai, M.D., M.S., and Georg Oeltzschner, Ph.D., also highlighted their research. Bai offered a look at use of artificial intelligence in imaging patients who have COVID-19, and Oeltzschner’s presentation focused on choline and N-acetylaspartate levels in patients with glioma.

As the afternoon continued, several esteemed radiology professors presented their research. Hanzhang Lu, Ph.D., and Atif Zaheer, M.D., focused on MRI, with Lu examining imaging in brain diseases and Zaheer discussing use of biomarkers to predict diabetes following acute pancreatitis. The presentations concluded with George Sgouros, Ph.D., discussing radiopharmaceutical therapy in cancer treatments.

Final remarks at Research Day.

The day’s events concluded with final remarks and pre-clinical and clinical poster awards.

The 2022 Radiology Research Day offered many exciting and engaging ideas — from using artificial intelligence as an aid in the reading room to developing radiotherapies to treat cancer. Wherever the science goes, faculty members and researchers in the Johns Hopkins radiology department are sure to be on the cutting edge.

2019 Research Day

The third annual Radiology Research Day was a tremendous success.

  • Department Chair, Dr. Karen Horton, began with an introduction that highlighted spectacular new equipment being updated and installed primarily for research purposes. 

    The first distinguished faculty lecture was by Dr. Katarzyna Macura who gave an eye-opening talk on a vast amount of multi-disciplinary research and clinical work focused on prostate cancer.

  • The keynote lecture from Dr. Daniel Ford was an excellent discussion of translational research that covered challenges in medicine and the need to build efficient infrastructure to best support faculty efforts.

    Over lunch, the Turner Concourse was bursting with activity as poster presentations and judging took over the atmosphere.

  • In the Darner Conference Room, Core Service Centers displayed services available to all faculty both within and outside of the School of Medicine, in order to provide support for conducting cutting-edge research. The post-lunch series started with Dr. Shadpour Demehri and focused on his specialty in osteoarthritis imaging.

    Dr. Stefan Zimmerman discussed minimally-invasive cardiac CT and MRI imaging to diagnose subtle signs of abnormal function. Dr. Ferdinand Hui offered tremendous insight into strokes, the leading cause of adult disability and 5th leading cause of death.

    The last distinguished faculty lecture was by Dr. Paul Bottomley who discussed the history and progress of measuring cardiac work and his own involvement which dated back to 1977 when he helped build the first MRI as a young PhD student in Nottingham. Dr. Karen Horton concluded the day with handing out awards for the 6 poster winners.

    With every conclusion a new research question can be asked and a new step into progressing medicine may occur. Being a leader in treating patients means leading in medical research.

    The 2019 Radiology Research Day has revealed many conclusions and just as many newly surfaced questions, exactly what is needed to push medicine to the next frontier.
