This study aimed to determine the correlation between intravoxel incoherent motion (IVIM) and multiphase dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) quantitative parameters in patients with rectal cancer. ⋯ IVIM perfusion-related parameters, especially f·D*, demonstrated moderate correlations with DCE-MRI quantitative parameters in rectal cancer.

There is lack of consensus on managing papillomas due to varied upgrade rates in the literature related to variability in the studied populations. We specifically studied upgrade rates of pure papilloma diagnosed with ultrasound core biopsy (UCB) using spring-loaded (SLB) and vacuum-assisted (VAB) biopsy devices in patients with low-to-intermediate pre-test probability for malignancy on imaging. ⋯ BI-RADS 3, 4a, or 4b masses biopsied with UCB revealed pure papilloma upgrade to malignancy in less than 2% of cases. SLB was associated with greater upgrades compared with VAB. Therefore, follow-up imaging is a reasonable alternative to excision, particular in those sampled by VAB. Excision could be considered if the diagnosis of a high-risk lesion would change clinical management.

To evaluate whether parameters from empirical mathematical model (EMM) for ultrafast dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) correlate with histological microvessel density (MVD) in invasive breast cancer. ⋯ The parameters of the EMM, especially the initial slope or Aα, for ultrafast DCE-MRI correlated with MVD in invasive breast cancer.

To explore downstream costs associated with incidental pulmonary nodules detected on CT. ⋯ Downstream costs for incidental pulmonary nodules are highly variable and particularly high when ordering physicians over-manage relative to radiologist recommendations and Fleischner Society guidelines. To reduce unnecessary utilization and cost from over-management, radiologists may need to assume a greater role in partnering with ordering physicians to ensure appropriate, guideline-adherent, and follow-up testing.

To develop and disseminate an automated item generation (AIG) system for retrieval practice (self-testing) in radiology and to obtain trainee feedback on its educational utility. ⋯ AIG enabled self-testing is technically feasible, and is perceived positively by radiology residents as useful to their education.
