Didactic lectures are an integral component of resident education, but many are missed because of postcall or away rotation status. The authors describe their pilot experience implementing an audiovisual recording program for didactic lectures and report residents' and faculty members' perceptions of this experience. ⋯ On the basis of its affordability, perceived usefulness by residents, and minimal impact on faculty members' preparation time, a recording system for didactic lectures has the potential to enhance residents' learning at only minimal costs to radiology departments.

Clinical Trial
The efficiency of PC-MRI in diagnosis of normal pressure hydrocephalus and prediction of shunt response.
In this prospective study, we aimed to reveal the efficiency of phase-contrast magnetic resonance imaging (PC-MRI) in the diagnosis of idiopathic normal pressure hydrocephalus (INPH) and prediction of shunt response. ⋯ The measurement of CSF venous flow velocities with PC-MRI is a noninvasive test that benefits INPH diagnosis, but remains inadequate in prediction of response against shunt treatment.

Pulmonary vascular alteration is one of the characteristic features of chronic obstructive pulmonary disease (COPD). Recent studies suggest that vascular alteration is closely related to endothelial dysfunction and may be further influenced by emphysema. However, the relationship between morphological alteration of small pulmonary vessels and the extent of emphysema has not been assessed in vivo. The objectives of this study are: to evaluate the correlation of total cross-sectional area (CSA) of small pulmonary vessels with the extent of emphysema and airflow obstruction using CT scans and to assess the difference of total CSA between COPD phenotypes. ⋯ Total CSA of small pulmonary vessels at sub-subsegmental levels strongly correlates with the extent of emphysema (%LAA-950) and reflects differences between COPD phenotypes.
