Semiautomated Ventilation Defect Quantification in Exercise-induced Bronchoconstriction Using Hyperpolarized Helium-3 Magnetic Resonance Imaging

Rationale and Objectives This study aimed to compare the performance of a semiautomated ventilation defect segmentation approach, adaptive K -means, with manual segmentation of hyperpolarized heli...

Scapholunate Interosseous Ligament Tears

Rationale and Objectives The study aimed to perform a systematic review and meta-analysis for evaluating the diagnostic accuracy of 1.5 Tesla and 3.0 Tesla magnetic resonance imaging (MRI), and ma...

Reliability, Validity, and Reader Acceptance of LI-RADS—An In-depth Analysis

Rationale and Objectives This study aimed to analyze interreader agreement and diagnostic accuracy of Liver Imaging Reporting and Data System (LI-RADS) in comparison to a nonstandardized 5-point s...

Peer Review

Does any radiologist actually like peer review (PR)? Do radiologists look forward to retrospectively checking a specific number of the cases to determine whether they agree with the previous interp...

Patient Access to Online Radiology Reports

Rationale and Objectives Our objective was to evaluate the frequency with which patients viewed their online radiology reports in relation to clinical and laboratory notes and identify sociodemogr...

Opportunistic Breast Density Assessment in Women Receiving Low-dose Chest Computed Tomography Screening

Rationale and Objectives Low-dose chest computed tomography (LDCT), increasingly being used for screening of lung cancer, may also be used to measure breast density, which is proven as a risk fact...

Modified Subtraction Coronary CT Angiography Method for Patients Unable to Perform Long Breath-Holds

Rationale and Objectives Severe calcifications of the coronary arteries are still a major challenge in coronary computed tomography (CT) angiography (CCTA). Subtraction CCTA using a 320-detector r...

Instituting a Low-dose CT-guided Lung Biopsy Protocol

Rationale and Objectives We aimed to evaluate whether implementation of a low-dose computed tomography (CT)-guided lung biopsy protocol, with the support of individual radiologists in the section,...

Erratum to “What Program Directors Think” III Results of the 2014/2015 Annual Surveys of the Association of Program Directors in Radiology (APDR)

In the original article, an author name was incorrectly spelled as “Tan Lucien H. Muhammed.” However, the correct spelling is “Tan Lucien H. Mohammed.” The publisher regrets any inconvenience cause...

Detecting Pulmonary Nodules in Lung Cancer Patients Using Whole Body FDG PET/CT, High-resolution Lung Reformat of FDG PET/CT, or Diagnostic Breath Hold Chest CT

Rationale and Objectives Pulmonary nodules can be missed on the non-breath hold computed tomography (CT) portion of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET...
