Ultrasound-Guided Introital Drainage Of Pyometrocolpos, I Kim, Ranjith Vellody, Hans G. Pohl, Karun Sharma, Kabir Yadav

Radiology Faculty Publications

Pyometrocolpos can be caused by congenital malformations such as distal vaginal atresia and imperforate hymen. Patients usually present with obstructive urinary tract infections, acute kidney injury, or sepsis. Percutaneous drainage of the infected fluid can help treat the patient; however, recurrence is of concern. In this case report, we present a case of a child with recurrent pyometrocolpos due to distal vaginal atresia despite initial percutaneous drainage. To our knowledge, this is the first report of ultrasound-guided introital drainage of pyometrocolpos with relief of symptoms obviating the need for repeat drainage or immediate surgery. © 2017

Successful Embolization Of A Enterocutaneous Fistula Tract With Onyx 34 Following Low Anterior Resection For Rectal Cancer., Hamza Rahimi, Anthony C Venbrux, Vincent Obias

Radiology Faculty Publications

Enterocutaneous fistulas (ECFs) can be one of the complications found after surgical intervention for rectal cancer. Interventional modalities consisting of surgical, endoscopic, and radiological methods are often implemented to treat postoperative symptomatic complications. We present the case of 61-year-old Caucasian man who presented to us with a recent diagnosis of rectal cancer that had invaded the levators as well as anteriorly into the prostate, and who underwent low anterior resection with a diverting loop ileostomy. The patient was found to have a persistent presacral abscess due to an ECF tract. This case highlights the off-label use of ethylene-vinyl alcohol copolymer …

Design And Development Of A Phantom For Tomosynthesis With Potential For Automated Analysis Via The Cloud., David Goodenough, Josh Levy, Hildur Olafsdottir, Ingvi Olafsson

Radiology Faculty Publications

This paper describes Development of a Phantom for Tomosynthesis with Potential for Automated Analysis via the Cloud. Several studies are underway to investigate the effectiveness of Tomosynthesis Mammographic Image Screening, including the large TMIST project as funded by the National Cancer Institute https://www.cancer.gov/about-cancer/treatment/clinical-trials/nci-supported/tmist. The development of the phantom described in this paper follows initiatives from the FDA, the AAPM TG245 task group, and European Reference Organization (EUREF) for Quality Assured Breast Screening and Diagnostic Services Committee report noting, that no formal endorsement nor recommendation for use has been sought, or granted by any of these groups. This paper reports on …

A Review Of Clinical Radioprotection And Chemoprotection For Oral Mucositis., Bryan Oronsky, Sharad Goyal, Michelle M Kim, Pedro Cabrales, Michelle Lybeck, Scott Caroen, Neil Oronsky, Erica Burbano, Corey Carter, Arnold Oronsky

Radiology Faculty Publications

The first tenet of medicine, "primum non nocere" or "first, do no harm", is not always compatible with oncological interventions e.g., chemotherapy, targeted therapy and radiation, since they commonly result in significant toxicities. One of the more frequent and serious treatment-induced toxicities is mucositis and particularly oral mucositis (OM) described as inflammation, atrophy and breakdown of the mucosa or lining of the oral cavity. The sequelae of oral mucositis (OM), which include pain, odynodysphagia, dysgeusia, decreased oral intake and systemic infection, frequently require treatment delays, interruptions and discontinuations that not only negatively impact quality of life but also tumor control …

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 …
