Using The Theory Of Planned Behavior As A Predictor Of Radiologic Technologists' Use Of Patient Radiation Protection Best Practices: A Regional Study, Brenda L. Boyd Aug 2019

Using The Theory Of Planned Behavior As A Predictor Of Radiologic Technologists' Use Of Patient Radiation Protection Best Practices: A Regional Study, Brenda L. Boyd

Brenda Boyd, PhD

Problem. A growing concern exists that patients are receiving an increase in radiation exposure while undergoing medical imaging exams. According to a March 2009 report by the National Council on Radiation Protection and Measurements (NCRP), the U.S. population's total exposure to ionizing radiation has nearly doubled over the past two decades. With the introduction of new digital radiology equipment, patient dose is on the rise. Possible reasons for a radiologic technologist's behavior include: influence by availability or lack of equipment, policies, social pressure, attitudes, and a safety culture. Little research has been done in this area, specifically ...

Quality And Safety Considerations In Breast Cancer Screening, Eugene Y. Kim, Laurie L. Fajardo

POG In Press

Breast cancer is a leading cause of premature mortality among United States women. Early detection has been shown to reduce breast cancer morbidity, mortality and cost of treatment. The relative safety of breast cancer screening has been viewed in terms of benefits and harms. The quality and safety of breast cancer screening depends on both technical and human factors. Focusing on quality and safety considerations, we review two imaging modalities recommended for primary breast cancer screening: mammography and magnetic resonance imaging, and the use of ultrasound (US) for supplemental breast cancer screening.

Increased 18f-Fdg-Pet Uptake In Granulomatosis With Polyangiitis: Case Report And Review Of The Literature, Rama El-Yafawi, Patricia Cantlin, Thomas E. Van Der Kloot Jun 2019

Increased 18f-Fdg-Pet Uptake In Granulomatosis With Polyangiitis: Case Report And Review Of The Literature, Rama El-Yafawi, Patricia Cantlin, Thomas E. Van Der Kloot

Journal of Maine Medical Center

We present an unusual case of granulomatosis with polyangiitis (GPA), which initially presented as a large lung mass, without renal or other systemic features. The lung mass was most concerning for malignancy, and positron emission tomography (PET) further supported this concern, with intense uptake in the mass as well as in mediastinal and hilar lymph nodes. Biopsies however were non-diagnostic, and the patient developed acute kidney injury with active urinary sediment, leading to a definitive diagnosis of GPA. With supportive care and treatment directed at GPA, she was ultimately able to discontinue hemodialysis, and the lung mass resolved. This case ...

BACKGROUND: To determine if adults with incident accelerated knee osteoarthritis (KOA) are more likely to have degenerative knee ligaments or tendons compared to individuals with typical or no KOA.

METHODS: We identified 3 sex-matched groups among Osteoarthritis Initiative participants who had a knee without radiographic KOA at baseline (Kellgren-Lawrence [KL] < 2): 1) accelerated KOA: at least 1 knee had KL grade > /= 3 in < /=48 months, 2) typical KOA: at least 1 knee increased in radiographic scoring within 48 months, 3) no KOA: both knees had the same KL grade at baseline and 48 months. We evaluated knee magnetic resonance images up to 2 years before and after a visit when the accelerated or typical KOA criteria were met (index visit). Radiologists reported degenerative signal changes for cruciate and collateral ligaments, and extensor mechanism and proximal gastrocnemius tendons. We used generalized linear mixed models with 2 independent variables: group and time.

RESULTS: Starting at least 2 years before onset, adults with accelerated KOA were twice as likely to have degenerative cruciate ligaments than no KOA (odds ratio = 2.10, 95% CI = 1.18, 3.74). A weaker association (not statistically significant) was detected for adults with accelerated versus typical ...

House Staff Quality Improvement and Patient Safety Posters

Introduction

While lacking evidence based recommendations, most institutions must evaluate spontaneous intracerebral hemorrhages (sICH) for hematoma expansion (HE). If unrecognized, it can be a devastating complication. However, because of the lack of general recommendations for serial imaging, many hospitals, including Thomas Jefferson, have arbitrarily instituted 6 hour an 24 hour stability head CT’s to evaluate for HE.

In our project, we examine the impact of this imaging protocol on the safety and quality of patient care and provide revised recommendations for imaging in sICH at Thomas Jefferson University Hospital and Jefferson Hospital for Neuroscience.

Benign Breast Cyst In A Young Male, Nima Azimi, Azniv Azar, Ashraf Khan, Carolynn M. Debenedectis

Radiology Publications and Presentations

Simple benign breast cysts are commonly diagnosed in female breasts and may present as palpable masses. However, they are extremely uncommon in the male breast and are rarely reported in the literature. Here, we report a case of a simple benign cyst of the breast in a relatively healthy 37-year-old man. The patient initially presented with a palpable 2-3 mm tender left breast lump. Further evaluation with mammography and ultrasound revealed a mass most consistent with a simple benign cyst. However, considering the rarity of breast cysts in males, the lesion was biopsied to rule out malignancy. Pathology results from ...

Scintillation Event Localization In Novel Hemi-Ellipsoid Detector For Spect, Hanif R. Soysal May 2019

Scintillation Event Localization In Novel Hemi-Ellipsoid Detector For Spect, Hanif R. Soysal

LSU Master's Theses

A high sensitivity Cardiac SPECT system using hemi-ellipsoid crystals with pinhole collimation was previously proposed by Dey et al. To investigate detector resolution for this design, the scintillation light spread on a monolithic hemi-ellipsoidal CsI crystal was simulated using Geant4 Monte Carlo. The expected distribution of scintillation light on the outer surface of the crystal from photoelectric absorption events was obtained from the simulations for selected points inside the crystal. Two sets of simulations were performed. For the first set, a look-up table (LUT) of 12 points was created and each point mapped to its expected light distribution—four points ...
