Rationale and Objectives To study the effects of four different rigid alignment approaches on both time-concentration curves (TCCs) and perfusion maps in computed tomography perfusion (CTp) studie...

Rationale and Objectives Hyperpolarized 3 He magnetic resonance imaging (MRI) previously revealed the temporal and spatial heterogeneity of ventilation defects in asthmatics, but these findings h...

Rationale and Objectives To investigate the impact of breast density on the performance of radiologists when mammograms are digitally acquired and displayed. Materials and Methods A total of 150...

Rationale and Objectives The purpose of this study was to provide normal values of volumetry and linear dimensions of adrenal glands. Materials and Methods Contrast-enhanced multidetector comput...

Rationale and Objectives To retrospectively investigate the effect of flip angle (FA) and k -space sampling on the performance of dynamic contrast-enhanced (DCE-) magnetic resonance imaging (MRI) ...

The quality of our performance hinges on what we know, which in turns hinges on the quality of our education. Formal education can take many forms: solitary or shared, passive or active, live or vi...

Rationale and Objectives To determine the impact of mammographic breast density on the visual search process of radiologists when reading digital mammograms. Materials and Methods Institutional ...

Rationale and Objectives The objective of this study was to assess whether changes to radiographic parameters before and after treatment with antiangiogenic drugs would improve performance in pred...

Imaging has evolved to play a unique role in the fight against cancer, as a tool both for screening and detection and for assessing the extent and severity of any cancer found. The ultimate goal of...

Rationale and Objectives As breast magnetic resonance imaging (MRI) use grows, benchmark performance parameters are needed for auditing and quality assurance purposes. We describe the variation in...
