The sensitivity and specificity of chest CT in the diagnosis of COVID-19.

Purpose: The identification of patients infected by SARS-CoV-2 is highly important to control the disease; however, the clinical presentation is often unspecific and a large portion of the patients develop mild or no symptoms at all. For this reason, there is an emphasis on evaluating diagnostic tools for screening. Chest CT scans are emerging as a useful tool in the diagnostic process of viral pneumonia cases associated with COVID-19.

[Testicular adrenal rest tumor in the background of congenital adrenal hyperplasia].

The prevalence of testicular adrenal rest tumours varies in different forms of congenital adrenal hyperplasia. Patients with 21-hydroxilase deficiency usually have bilateral and palpable testicular nodules. Although adrenal rest tumours are well documented in the literature, the diagnosis and management require a multidisciplinary approach: the cooperative work of endocrinologists, urologists, pathologists and radiologists is essential.

External Factors That Influence the Practice of Radiology: Proceedings of the International Society for Strategic Studies in Radiology Meeting.

In both the United States and Europe, efforts to reduce soaring health care costs have led to intense scrutiny of both standard and innovative uses of imaging. Given that the United States spends a larger share of its gross domestic product on health care than any other nation and also has the most varied health care financing and delivery systems in the world, it has become an especially fertile environment for developing and testing approaches to controlling health care costs and value. This report focuses on recent reforms that have had a dampening effect on imaging use in the United States and provides a glimpse of obstacles that imaging practices may soon face or are already facing in other countries.
