BACKGROUND Delirium is common in hospitalized patients and warrants early diagnosis and treatment. Often the evaluation of delirium includes head computed tomography imaging. However, in hospitalized medical patients, the yield of head computed tomography is unknown. OBJECTIVE To determine the diagnostic yield of head computed tomography when evaluating a hospitalized medical patient with del...

Abstract This chapter presents a regulatory science perspective on the assessment of machine learning algorithms in diagnostic imaging applications. Most topics are generally applicable to many medical applications, while brain disease-specific examples provided when possible. The begins with an overview US FDA’s framework followed by methodologies related ML devices imaging. Rationale, methods...

The history of medical imaging can be dated from Rontgen’s discovery and first clinical use of X-rays in 1895. These first X-ray images were humble portents of the increasingly important role which medical imaging has assumed, particularly in the last 25 years. In fact, diagnostic radiology continued more or less unchanged from Rontgen’s discovery until digital computers were integrated with el...

Advanced medical imaging and visualization has a strong impact on research and clinical decision making in gastroenterology. The aim of this paper is to show how imaging and visualization can disclose structural and functional abnormalities of the gastrointestinal (GI) tract. Imaging methods such as ultrasonography, magnetic resonance imaging (MRI), endoscopy, endosonography, and elastography w...

Medical imaging has a remarkable role in the practice of clinical medicine. This study intends to evaluate the knowledge of indications of five common medical imaging modalities and estimation of the imposed cost of their non-indicated requests among medical students who attend Shiraz University of Medical Sciences, Shiraz, Iran. We conducted across-sectional survey using a self-administered qu...

Medical microwave imaging techniques seek to exploit dielectric-properties contrast mechanisms that are sensitive to physiological or pathological factors of clinical interest. The dawn of the 21st century has brought exciting prospects for innovative microwave sensing technologies to address diagnostic needs in medicine, particularly early-stage breast cancer detection. Yet numerous challenges...
