Preoperative Pulmonary Vascular Morphology and Its Relationship to Postpneumonectomy Hemodynamics

Rationale and Objectives Pulmonary edema and pulmonary hypertension are postsurgical complications of pneumonectomy that may represent the remaining pulmonary vasculature’s inability to accommodat...

Preferences for Structured Reporting of Measurement Data

Rationale and Objectives The aim of this study was to determine whether key radiology report “consumers” in our institution prefer structured measurement reporting in a dedicated report section ov...

Optimizing Image Contrast Display Improves Quantitative Stenosis Measurement in Heavily Calcified Coronary Arterial Segments on Coronary CT Angiography

Rationale and Objectives Blooming artifact from calcified plaques often renders measurement of stenosis impossible on coronary computed tomographic angiography (CTA). We sought to evaluate the imp...

Optimal Timing and Diagnostic Adequacy of Hepatocyte Phase Imaging with Gadoxetate-Enhanced Liver MRI

Rationale and Objectives To evaluate clinical and imaging features associated with adequacy of the hepatocyte phase (HP) in gadoxetate disodium–enhanced liver magnetic resonance imaging (MRI) in p...

Model-based Iterative Reconstruction Compared to Adaptive Statistical Iterative Reconstruction and Filtered Back-projection in CT of the Kidneys and the Adjacent Retroperitoneum

Rationale and Objectives To prospectively evaluate the perceived image quality of model-based iterative reconstruction (MBIR) compared to adaptive statistical iterative reconstruction (ASIR) and f...

Mass and Fat Infiltration of Intercostal Muscles Measured by CT Histogram Analysis and Their Correlations with COPD Severity

Rationale and Objectives Chronic obstructive pulmonary disease (COPD) is characterized by progressive respiratory function impairment and respiratory muscle dysfunction. We hypothesized that the m...

Learner Confidence

Life is arduous, difficult, a perpetual struggle. It calls for gigantic courage and strength. More than anything, perhaps, creatures of illusion as we are, it calls for confidence in oneself. Wi...

Geometric Distortion in Diffusion-weighted MR Imaging of the Prostate—Contributing Factors and Strategies for Improvement

Rationale and Objectives Image distortion on diffusion-weighted imaging (DWI) of the prostate in 3T endorectal magnetic resonance imaging (MRI) examinations is common. The aim of this study was to...

Evaluation of Subchondral Bone Marrow Lipids of Acute Anterior Cruciate Ligament (ACL)-Injured Patients at 3 T

Rationale and Objectives The objectives of this study were to investigate the changes in compartment-specific subchondral bone marrow lipids of femoral–tibial bone in acute anterior cruciate ligam...

Evaluation of Coronary Artery Image Quality with Knowledge-based Iterative Model Reconstruction

Rationale and Objectives To evaluate knowledge-based iterative model reconstruction (IMR) to improve image quality and reduce radiation dose in coronary computed tomography angiography (cCTA). Ma...
