Monochromatic Spectral Computed Tomography with Low Iodine Concentration Contrast Medium in a Rabbit VX2 Liver Model

Rationale and Objectives This study aimed to validate the feasibility of using virtual monochromatic spectral computed tomography (CT) with isotonic low iodine concentration contrast medium for VX...

Lee Rosen, PhD

When you think of medical imaging research, a lot of names come to mind, but when you think of those having the most impact in terms of being an advocate for funding in radiology and imaging scienc...

Integrating Radiology and Anatomy Teaching in Medical Education in the UK—The Evidence, Current Trends, and Future Scope

This review article presents the current evidence of the importance of integrating radiology and anatomy in medical education in the UK, a recommendation by a number of key anatomy, education, and ...

Feasibility of Respiratory-gated High-pitch Spiral CT

Rationale and Objectives This study aimed to develop and implement a respiratory-gated setup for dual-source computed tomography (CT) at high pitch to examine patients in a reproducible inspirator...

Discrimination between Metastatic and Nonmetastatic Mesorectal Lymph Nodes in Rectal Cancer Using Intravoxel Incoherent Motion Diffusion-weighted Magnetic Resonance Imaging

Rationale and Objectives The aim of the study was to investigate the diagnostic value of intravoxel incoherent motion diffusion-weighted magnetic resonance imaging (IVIM DWI) for discriminating no...

Coronary Computed Tomographic Angiography at Low Concentration of Contrast Agent and Low Tube Voltage in Patients with Obesity

Rationale and Objectives Using lower tube voltage can reduce the exposure to radiation and the dose of contrast agent. However, lower tube voltage is often linked to more noise and poor image qual...

BI-RADS Density Classification From Areometric and Volumetric Automatic Breast Density Measurements

Rationale and Objectives The aim of our study was to classify breast density using areometric and volumetric automatic measurements to best match Breast Imaging-Reporting and Data System (BI-RADS)...

A Robust Emphysema Severity Measure Based on Disease Subtypes

Rationale and Objectives We propose a novel single index for the quantification of emphysema severity based on an aggregation of multiple computed tomographic features evident in the lung parenchy...

A Resident Perspective on Adding Value as Radiologists

During the annual 46th annual American Alliance of Academic Chief Residents in Radiology (A 3 CR 2 ) meeting in New Orleans, chief residents discussed the role of residents within American Colleg...

Volumetric Tumor Response and Progression in EGFR -mutant NSCLC Patients Treated with Erlotinib or Gefitinib

Rationale and Objectives The aims of this study were to investigate the association between 8-week tumor volume decrease and survival in an independent cohort of epidermal growth factor receptor (...
