The Pivotal Role Of Mri In The Diagnosis Of Listeria Rhomboencephalitis, K.R Uprety, M Reza Taheri

GW Research Days 2016 - 2020

Sixty-six year-old female presented to the Emergency Department with history of several days of headache, malaise, chills, and fatigue with accompanying nausea, vomiting, and inability to tolerate oral intake. She had no history of fever and remained afebrile at the time of presentation. Physical exam and immediate lab values were non-contributory; CSF was obtained and sent for analysis. The patient was placed preemptively on acyclovir, as viral meningitis was the admitting diagnosis. MRI of the brain showed abnormal FLAIR signal hyperintensity and enhancement involving the entire cisternal segment of the left trigeminal nerve, which extended dorsally along the nerve fiber …

Breast Lesions Detected Via Molecular Breast Imaging: Physiological Parameters Affecting Interpretation, Jason Ching, Rachel Brem

GW Research Days 2016 - 2020

Rationale and Objectives:

To evaluate correlations between molecular breast imaging (MBI) descriptor characteristics and positive predictive value (PPV) in detecting breast cancer.

Materials and Methods:

A retrospective review was performed on 193 suspicious findings from 153 women (31-81 years) with positive MBI examinations. We assessed associations between: (i) lesion pattern (mass vs. non-mass) and PPV; (ii) lesion pattern and suspected likelihood of cancer (low vs. moderate vs. high); (iii) background parenchymal uptake (BPU) (homogeneous vs. heterogeneous) and PPV; (iv) breast density (dense vs. non-dense) and PPV; (v) BPU and density.

Results:

One hundred ten of 153 patients were diagnosed with …

Enriching The Medical Student Radiology Clerkship: Simulating The Radiologist’S Experience, Liqi Shu, Faraien Bahri, Navid Mostaghni, Ramin Javan

GW Research Days 2016 - 2020

Background

Current radiology training in medical schools is still predominantly limited to passively observing the radiologist at the workstation and through lectures, textbooks and online sources. Evaluation is also mainly limited on still image interpretation or knowledge-based multiple-choice questions. Furthermore, students may have specific interests based on their choice of residency. In order to create a tailored and active learning experience, and to evaluate students’ ability in image interpretation, we utilized an open-source web-based Picture archiving and communication system (PACS) named "Weasis" and integrated a report system.

Method

We establish a new PACS teaching system by utilizing the open-source PACS …
