OBJECTIVE: The purpose of this article is to review the literature on communicating transparency in health care pricing, both overall and specifically for medical imaging. Focus is also placed on the imperatives and initiatives that will increasingly impact radiologists and their patients. CONCLUSION: Most Americans seek transparency in health care pricing, yet such discussions occur in fewer than half of patient encounters. Although price transparency tools can help decrease health care spending, most are used infrequently and most lack information about quality...

BACKGROUND: Besides the expected warm and joyful thoughts, a new mother can be disturbed by sudden frightening thoughts or images of harm done to her baby: harming intrusions, an obsessive phenomenon. Its high prevalence and possible consequences in functioning and in mother-child bonding makes it desirable that clinicians are well informed regarding the current state of knowledge about harming intrusions. OBJECTIVE: To provide a comprehensive review of all studies that have investigated harming intrusions in postpartum women...

The combination of medical imaging with computational fluid dynamics (CFD) has enabled the study of 3D blood flow on a patient-specific level. However, with models based on gated high-resolution data, the study of transient flows, and any model implementation into routine cardiac care, is challenging. The present paper presents a novel pathway for patient-specific CFD modelling of the left ventricle (LV), using 4D transthoracic echocardiography (TTE) as input modality. To evaluate the clinical usability, two sub-studies were performed...

Diffeomorphic deformation is a popular choice in medical image registration. A fundamental property of diffeomorphisms is in vertibility, implying that once the relation between two points A to B is found, then the relation B to A is given per definition. Consistency is a measure of a numerical algorithm's ability to mimic this invertibility, and achieving consistency has proven to be a challenge for many state-of-the-art algorithms.

Debate on the proper timing of pulmonary valve replacement (PVR) after repair of tetralogy of Fallot is still continuing. We aim to clarify how the different components of right ventricle (RV) changed with relieved volume overload in the remodeling process after pulmonary valve replacement and gain a clear idea of the relationship between different right ventricle components function and exercise capacity after PVR in these patients. The medical records and results of cardiac magnetic resonance imaging and cardiopulmonary exercise testing of 25 consecutive eligible patients were reviewed...

Central airway obstructive infections (CAOI) are challenging medical conditions that may represent an advanced and complicated process of ongoing infections. The epidemiology of CAOI is unknown as well as the pathophysiology and the mechanism of development. This is due to sparse data in the literature that consists mainly of case reports and retrospective case series. CAOI can be caused by fungal, bacterial, parasitic and viral infections. Most patients with CAOI can be diagnosed clinically and with chest imaging, which demonstrate obstruction of the central airways...

INTRODUCTION: Complex regional pain syndrome (CRPS) is a major complication after trauma, surgery, and/or immobilization of an extremity. The disease often starts with clinical signs of local inflammation and develops into a prolonged phase that is characterized by trophic changes and local osteoporosis and sometimes results in functional impairment of the affected limb. While the pathophysiology of CRPS remains poorly understood, increased local bone resorption plays an undisputed pivotal role...

BACKGROUND AND OBJECTIVE: Patients with Alzheimer's disease (AD) are frequently unaware of their cognitive symptoms and medical diagnosis. The term "anosognosia" is used to indicate a general lack of awareness of one's disease or disorder. The neural substrate underlying anosognosia in AD is unclear. Since anosognosia for memory disturbance might be an initial sign of AD, it is important to determine the neural correlates. This study was designed to investigate the characteristics and neural correlates of anosognosia for memory disturbance in patients with mild AD...

BACKGROUND CONTEXT: Distractive-flexion injuries (DFIs) of the subaxial cervical spine are major contributors to spinal cord injury (SCI). Prompt assessment and early intervention of DFIs associated with SCI is crucial to optimize patient outcome; however, neurological examination of patients with subaxial cervical injury is often difficult, as patients commonly present with reduced levels of consciousness. Therefore, it is important to establish potential associations between injury epidemiology and radiographic features, and neurological involvement...
