Preparation for clinical practice in radiology: a survey of interns and radiologists
… A sample of Irish interns and practicing radiologists were asked to complete a quantitative survey regarding perceptions of intern readiness to interact with the radiology department. A mixed quantitative/qualitative analysis using group concept mapping was also conducted involving …

Business model and strategy analysis for radiologists to use electronic health records (EHR)
… imaging requirements, leading to confusion among radiologists and other specialties with regard to what MU offers to and requires of them. This thesis attempts to clarify the contribution radiology can make to MU by understanding radiology as a system, including its surrounding issues and its …

The evaluation of chest images compressed with JPEG and wavelet techniques
… due to compression may not be acceptable to radiologists or it may affect diagnostic results. A preliminary study was conducted using several chest images with common lung diseases and compressed with JPEG and wavelet techniques at various ratios. Twelve board-certified radiologists were …

A spatial structuring approach to IT use and workplace change : what's space got to do with it?
… uses the disparate spatial practices of radiologists and outpatient physicians to frame a study of the relationship between space, information technology use and workplace change, with a particular focus on relationships of control. Drawing from diverse urban, organization and economic …

The utility of abdominal ultrasound in the diagnosis of paediatric abdominal tuberculosis: a single centre review
… the variability in reporting patterns amongst radiologists performing these imaging investigations. Materials and methods: Ultrasound studies performed for “suspected abdominal TB” between 01 January 2013 – 31 December 2018 were reviewed. In studies reported as suggestive of abdominal TB, …

The risks of medical imaging: a survey of doctors' knowledge and consenting practice
… of knowledge between referring clinicians and radiologists regarding the risks to patients undergoing medical imaging and to explore doctors' attitudes toward consenting practice. Method: A cross sectional, observational, descriptive study design was employed. The study was conducted using a …

An Integrated Delivery Model For Providing On-Site and Remote Radiology Services To Rural Midwest Hospitals
… to send images off-site to sub-specialist radiologists. These enhancements were intended to improve the quality and consistency of radiology interpretations without negatively impacting the necessary turnaround time of results provided to referring clinicians treating patients. This …

SHAPE INFLUENCE IN MEDICAL IMAGE SEGMENTATION WITH APPLICATION IN COMPUTER AIDED DIAGNOSIS IN CT COLONOGRAPHY
… (CAD) is a procedure in medicine that assists radiologists or physicians in the interpretation of medical images. The application of CAD in screening colorectal cancer (CRC) has been studied for more than two decades. CRC is the second most deadly form of cancer in men and women in the United …

A remote access CT colonography training system
… use due in part to the lack of suitably trained radiologists. We have developed a novel remote access system to train radiologists for colorectal cancer screening using CTC. To ensure that radiologists can gain the relevant experience without the need for any specialist equipment or software, we …

Healthy Behavior: Essays in Health and Behavioral Economics
… common and consequential medical task. It casts radiologists as facing a classical decision-theory problem, derives a novel martingale test for optimal behavior, and implements this test through a prudent application of machine learning to anonymized health records from the Beth Israel Deaconess …

The development of specialisation in diagnostic radiography : concepts, contexts and implications
… emphasis has roots in power difference between radiologists and radiographers and within the hierarchy of radiography. Radiologists have controlled radiographers to provide a service to radiology rather than the patients, and, although this is still evident in some hospitals, it is changing. …

Optimization of Fast MR Imaging Technologies using the Case-PDM to Quantitatively Assess Image Quality
… In almost all cases, images will be viewed by radiologists to make a diagnosis, to stage a disease, to apply a treatment, and/or to assess a treatment. Since images are viewed, one needs to assess visual image quality, preferably in a quantitative way. We developed a perceptual difference …

Analysis of MRI in the diagnosis of myositis
… images are reportedfollowing visual analysis by radiologists. In this research, two approacheswere used to improve the diagnosis of Myositis with the aid of MRI:First: by using IDL PC software (In-house software developed toquantitatively analyse MR images and categorises its pixels according …

Essays on Online Platforms and Human-Algorithm Interaction
… an information experiment with professional radiologists. Results show that providing (i) AI predictions does not always improve performance, whereas (ii) contextual information does. Radiologists do not realize the gains from AI assistance because of errors in belief updating – they …

Imaging Based Models to Improve Lung Cancer Diagnosis
… and act as an objective second reader, or help radiologists flag risky exams. The task of localization of both present and future cancers can help radiologists ascertain current and future regions of interest that should be further examined. The task of incorporating image priors allows the risk …

Computer aided diagnosis of miliary TB in chest X-rays
… becoming an increasingly more powerful tool for radiologists. The focus of this project was on CAD of pulmonary miliary tuberculosis. Several methods for enhancing lung textures were discussed as an aid to the radiologist in diagnosing miliary TB. Some statistical approaches and template matching …

Synthesizing a complete tomographic study with nodules from multiple radiograph views via deep generative models
… challenges even for the most experienced radiologists as many critical findings are superimposed, often resulting in error or further imaging. In particular, it is difficult to visualize the volume and density of lung nodules in chest radiographs. A deep generative model, commonly used to …

Mammographic density in relation to breast cancer Tumor characteristics, mode of detection, and density assessments
… and Data System (BI-RADS) score from different radiologists and moderate agreement between the BI-RADS score and the fully automated volumetric assessment (Volpara software) of mammographic density. This thesis shows that some of the mammographic tumor features and the pathological tumor …

Improving breast cancer risk assessment with image-based deep learning models
… limited in that they suffer from variability in radiologists' assessments and they reduce the rich information contained in the image down to a single number. In this thesis, I present deep learning models that predict breast cancer risk directly from full images, specifically breast MRIs and …
