Rationale and Objectives Pulmonary functional imaging using four-dimensional x-ray computed tomographic (4DCT) imaging and hyperpolarized 3 He magnetic resonance imaging (MRI) provides regional l...

Rationale and Objectives The accuracy of medical tests is often assessed using the area under the entire receiver-operating characteristic (ROC) curve. However, this includes values that might be ...

Rationale and Objectives The aim of this study was to evaluate if a dose-reduced, dose-neutral dual-energy computed tomographic (CT) virtual noncalcium technique can equally detect posttraumatic b...

Charles Edgar Metz, professor of radiology and a member of the Committee on Medical Physics at the University of Chicago, died from pancreatic cancer on July 4 at his home in Burr Ridge. He was 69 ...

With the growing focus on comparative effectiveness research and personalized medicine, receiver-operating characteristic analysis can continue to play an important role in health care decision mak...

Rationale and Objectives Studies of medical image interpretation have focused on either assessing radiologists’ performance using, for example, the receiver operating characteristic (ROC) paradigm...

Rationale and Objectives The partial area under the receiver operating characteristic (ROC) curve (pAUC) is a useful summary measure for diagnostic studies. Unlike most summary measures that are f...

Many of the patients imaged in radiology departments each day spend time in a waiting room. Some, particularly those who return for multiple examinations, may become quite familiar with it. Yet the...

Rationale and Objectives For the evaluation of patients scheduled for the treatment of brain arteriovenous malformations (AVMs), accurate anatomical information is essential. The purpose of this s...

Rationale and Objectives The airway tree is a primary conductive structure, and airways’ morphologic characteristics, or variations thereof, may have an impact on airflow, thereby affecting pulmon...
