Multicenter Study
Image reporting and characterization system for ultrasound features of thyroid nodules: multicentric Korean retrospective study.
The objective of this retrospective study was to develop and validate a simple diagnostic prediction model by using ultrasound (US) features of thyroid nodules obtained from multicenter retrospective data. ⋯ The predictor model using suspicious malignant US features may be helpful in risk stratification of thyroid nodules.

Case Reports
Spontaneous massive hemothorax in a patient with neurofibromatosis type 1 with successful transarterial embolization.
Vascular involvement in neurofibromatosis type 1 is rare but has the potential to be fatal. We report a case of a patient with spontaneous rupture of a left intercostal artery aneurysm, which presented as a massive left hemothorax and was successfully treated by transarterial coil embolization.

We aimed to evaluate the use of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) at 3.0 T for differentiating the benign from malignant soft tissue tumors. Also we aimed to assess whether the shorter length of DCE-MRI protocols are adequate, and to evaluate the effect of temporal resolution. ⋯ The steepest slope and early relative enhancement have the potential for differentiating benign from malignant soft tissue tumors. Short-length rather than long-length DCE-MRI protocol may be adequate for our purpose. The steepest slope parameters require a short temporal resolution, while maximal peak enhancement parameter may be more optimal for a longer temporal resolution.
