A Reader Study Comparing Prospective Tomosynthesis Interpretations with Retrospective Readings of the Corresponding FFDM Examinations

Rationale and Objectives To compare performance of prospective interpretations of clinical tomosynthesis (digital breast tomosynthesis [DBT]) plus full-field digital mammography (FFDM) examination...

Work and Retirement Preferences of Practicing Radiologists as a Predictor of Workforce Needs

Rationale and Objectives The radiology job market has been described as highly variable, and recent practice hiring surveys predict that the number of available jobs will remain flat. Radiologists...

Tumor Response Assessment Using Volumetric Doubling Time

Imaging is commonly used to assess tumor response to novel therapies in oncology clinical trials. As a surrogate marker to predict the clinically relevant factors of time to progression or patient ...

Tumor Growth Kinetics Versus RECIST to Assess Response to Locoregional Therapy in Breast Cancer Liver Metastases

Rationale and Objectives The aim of our study was to evaluate changes in growth kinetics of breast cancer liver metastasis in response to locoregional therapy and compare them to Response Evaluati...

Three-dimensional MRI Assessments of Patchy and Large Myocardial Infarction in Beating and Nonbeating Swine Hearts

Rationale and Objectives To measure and validate patchy and large myocardial infarction (MI) at 3 days and 5 weeks in beating and nonbeating hearts using contrast-enhanced three-dimensional (3D) i...

The Golden Rule of Education

Education’s golden rule Where do great educators come from? Are they born or made? If nurture, as opposed to nature, plays at least some role in their development, what kind of experiences seem to...

Phase-contrast MRI for Detection of Mild Systemic Hemodynamic Response after Segmental Allergen Challenge in Asthmatic Patients

Rationale and Objectives Detection of a systemic hemodynamic response in patients suffering from allergic asthma after segmental endobronchial allergen challenge using phase-contrast magnetic reso...

Optimal Pancreatic Phase Delay with 64-Detector CT Scanner and Bolus-tracking Technique

Rationale and Objectives To assess the optimal pancreatic phase delay in terms of parenchymal enhancement and tumor-to-pancreas contrast with a bolus-tracking method. Materials and Methods Patie...

Neurochemical Changes Observed by In Vivo Proton Magnetic Resonance Spectroscopy in the Mouse Brain Postadministration of Scopolamine

Rationale and Objectives This study is aimed at investigating neurochemical changes in scopolamine (SCP)–induced memory impairment using spatially localized in vivo magnetic resonance spectroscopy...

Magnetic Resonance Assessment of Pulmonary (QP ) to Systemic (QS ) Flows Using 4D Phase-contrast Imaging

Rationale and Objectives To investigate four-dimensional (4D) phase-contrast (PC) magnetic resonance (MR) in the evaluation of intracardiac shunts by simultaneous assessment of pulmonary (Q P ) a...
