Multicenter StudyTomosynthesis Impact on Breast Cancer Screening in Patients Younger Than 50 Years Old.
The question of benefits versus harms of breast cancer screening for women younger than 50 years old has been the subject of debate. We investigate if the addition of tomosynthesis to mammography improves screening performance outcomes for women in this age group. ⋯ Tomosynthesis in a community setting resulted in decreased recall rates for patients younger than 50 years old. For the subgroup of women with dense breast tissue, cancer detection rates also increased.

Comparative StudyComparison of DWI Methods in the Pediatric Brain: PROPELLER Turbo Spin-Echo Imaging Versus Readout-Segmented Echo-Planar Imaging Versus Single-Shot Echo-Planar Imaging.
The purpose of this study is to compare DWI for pediatric brain evaluation using single-shot echo-planar imaging (EPI), periodically rotated overlapping parallel lines with enhanced reconstruction (Blade), and readout-segmented EPI (Resolve). ⋯ DWI with Resolve or Blade yields better quality regarding distortion, susceptibility-related changes, and lesion conspicuity, compared with single-shot EPI. Blade is less susceptible to motion artifacts than is Resolve, whereas Resolve yields less noise and better lesion conspicuity than does Blade.

Comparative StudyComparison Between Image-Guided and Landmark-Based Glenohumeral Joint Injections for the Treatment of Adhesive Capsulitis: A Cost-Effectiveness Study.
The purpose of this study was to determine the cost-effectiveness of landmark-based and image-guided intraarticular steroid injections for the initial treatment of a population with adhesive capsulitis. ⋯ Ultrasound-guided injections are the most cost-effective option for the initial steroid-based treatment of patients with adhesive capsulitis. Blind and fluoroscopy-guided injections can also be cost-effective when performed by a clinician likely to accurately administer the medication into the correct location.

Novel Quality Indicators for Radiologists Interpreting Abdominopelvic CT Images: Risk-Adjusted Outcomes Among Emergency Department Patients With Right Lower Quadrant Pain.
The purpose of this study was to determine whether individual radiologists are predictive of important relevant health outcomes among emergency department (ED) patients undergoing abdominopelvic CT for right lower quadrant pain. ⋯ Individual radiologists were indistinguishable both within group and between group by emergency and abdominal specialization for the prediction of major patient outcomes after abdominopelvic CT performed for right lower quadrant pain in the ED.

Effect of Combined 68Ga-PSMAHBED-CC Uptake Pattern and Multiparametric MRI Derived With Simultaneous PET/MRI in the Diagnosis of Primary Prostate Cancer: Initial Experience.
The purpose of this study is to assess whether temporal changes in 68Ga-prostate-specific membrane antigen (PSMA)-HBED-CC uptake and multiparametric MRI parameters derived using PET/MRI can aid in characterization of benign and malignant prostate lesions. ⋯ Dual-phase PSMA uptake improves accuracy of classifying malignant versus benign prostate lesions and complements multiparametric MRI in the diagnosis of prostate cancer.
