First come, first observed: Utilizing observation as a pedagogical tool to transform leadership learning.

Leadership observation is a technique that relies on active and inactive recall to enhance learning through connecting theoretic concepts to real-world examples. This article makes the case that leadership observation should be thoughtfully used as a pedagogical tool to aid in students' leadership learning. Knowledge will be shared through personal narratives and practical strategies.

Image comparative assessment using iterative reconstructions: clinical comparison of low-dose abdominal/pelvic computed tomography between adaptive statistical, model-based iterative reconstructions and traditional filtered back projection in 65 patients.

Objectives: The objective of this study was to compare image quality (objective and subjective parameters) and confidence in lesion detection between 3 image reconstruction algorithms in computed tomographic (CT) examinations of the abdomen/pelvis.

Materials And Methods: This prospective institutional review board-approved study included 65 patients (mean [SD] age, 71.3 ± 9 years; mean [SD] body mass index, 24.

Image quality assessment of standard- and low-dose chest CT using filtered back projection, adaptive statistical iterative reconstruction, and novel model-based iterative reconstruction algorithms.

Objective: The purpose of this article is to compare image quality between filtered back projection (FBP), adaptive statistical iterative reconstruction (ASIR), and model-based iterative reconstruction (MBIR) at standard dose and two preselected low-dose scans.

Subjects And Methods: Thirty patients (16 men and 14 women; mean age, 67 years) were prospectively recruited. Patients underwent three scans (one standard-dose scan and two low-dose scans at noise indexes [NIs] of 33, 60, and 70, respectively).

Coronary arterial microfistulae: a CT coronary angiography perspective.

Coronary arterial microfistulae are abnormal connections between one or multiple coronary arteries and any cardiac chamber, vein, or thoracic vessel. They comprise a subsection of coronary fistulas where the abnormal connections are diffuse, as opposed to the larger, more common single vessel varieties. Most of these anomalies are detected incidentally on catheter angiography; however, we present this anomaly as a case report from the perspective of CT coronary angiography.
