The Impact Of Virtual Radiographic Positioning Simulation On 1St Year Radiography Students’ Clinical Preparedness Through The Lens Of Activity Theory: A Mixed Method Approach, Christopher Ira Wertz 2021 Boise State University

The Impact Of Virtual Radiographic Positioning Simulation On 1St Year Radiography Students’ Clinical Preparedness Through The Lens Of Activity Theory: A Mixed Method Approach, Christopher Ira Wertz

Boise State University Theses and Dissertations

Radiography education programs are designed to prepare students to perform radiographic examinations and acquire diagnostic medical images of real patients in the clinical setting. Radiographic Science (RS) education, like all healthcare education, is uniquely different from education in other professional fields. Students must not only acquire the technical, cognitive learning required, but they must also master the psychomotor skills necessary to apply didactic knowledge to patients in a clinical setting. In medical imaging, when students are hesitant or lack knowledge and skills they are prone to produce images with decreased quality or expose patients to unnecessarily high amounts of radiation ...

Nonalcoholic fatty liver disease (NAFLD) affects up to 70% of children with obesity and has become the number one etiology for liver transplant in the United States. Early, effective intervention is critical to prevent disease progression into adulthood. Yet, it is seldom achieved through lifestyle modification alone. Thus, children must be included in NAFLD pharmacology trials, which, to date, continue to focus primarily on adult populations. This commentary serves as a call to action.

Recurrent Breast Cancer Diagnosis Delayed By Covid-19 Pandemic, Hannah K. Thompson, Paul J. Spicer

Radiology Faculty Publications

We describe the case of a 65-year-old female with a history of left-sided ductal carcinoma in situ in 2008. Mammography in January 2020 demonstrated calcifications in the previously affected breast. Subsequent stereotactic biopsy results were benign. In the months that followed, the patient experienced breast changes but avoided returning to the facility as the COVID-19 pandemic worsened. In August of 2020, the patient returned for a repeat mammogram, which indicated 2 suspicious masses in the left breast. Further analysis through ultrasound-guided core biopsy ultimately led to a left mastectomy and lymph node biopsy, which were performed in September 2020. Pathology ...

BACKGROUND: Endovascular thrombectomy is the process of removing a blood clot and re-establishing blood flow in patients with emergent large vessel occlusion. The technique provides an opportunity to deliver therapeutics directly to the site of injury. The intra-arterial (IA) route of drug administration in the mouse was developed to bridge the gap between animal stroke treatments and clinical stroke therapy. Here, we adapted the IA method for use in rats, by investigating various flow rates to optimize the IA injection through the internal carotid artery (ICA).

METHODS: Male and female Sprague-Dawley rats (∼4 months of age) were subjected to placement ...

Modelling The Impact Of Clot Fragmentation On The Microcirculation After Thrombectomy, Wahbi K. El-Bouri, Andrew Macgowan, Tamas I. Jozsa, Matthew J. Gounis, Stephen J. Payne

Radiology Publications

Many ischaemic stroke patients who have a mechanical removal of their clot (thrombectomy) do not get reperfusion of tissue despite the thrombus being removed. One hypothesis for this 'no-reperfusion' phenomenon is micro-emboli fragmenting off the large clot during thrombectomy and occluding smaller blood vessels downstream of the clot location. This is impossible to observe in-vivo and so we here develop an in-silico model based on in-vitro experiments to model the effect of micro-emboli on brain tissue. Through in-vitro experiments we obtain, under a variety of clot consistencies and thrombectomy techniques, micro-emboli distributions post-thrombectomy. Blood flow through the microcirculation is modelled ...
