The effect of an e-learning module on health sciences students' venipuncture skill development.

Introduction: Venipuncture is a psychomotor skill required in many healthcare professions. E-learning could be used to overcome current barriers in face-to-face learning in healthcare education such as insufficient classroom space or qualified instructors. We sought to evaluate the effectiveness of an e-learning module on students' performance when used in addition to in-class training.

Examining Practitioners' Assessments of Perceived Aesthetic and Diagnostic Quality of High kVp-Low mAs Pelvis, Chest, Skull, and Hand Phantom Radiographs.

This study investigated the usefulness of the dose optimization strategy of increased tube voltage (kVp) and decreased tube current-exposure time product (mAs) (or high kVp-low mAs) by examining practitioners' assessments of perceived aesthetic and diagnostic quality of direct digital radiographs acquired using this strategy. Ninety-one practitioners (radiologists, radiology residents, radiographers, and radiography students) from eight clinical sites in Ontario examined three types of radiographs ("standard" image, +20 kVp image, and +30 kVp image) for anthropomorphic pelvis, chest, skull, and hand phantoms and rated (on a five-point scale) each image in regard to its perceived aesthetic quality, perceived diagnostic quality, and visualization of anatomic structures. Our primary findings are that for the pelvis, skull, and hand-although not the chest-images acquired using standard technical factors were rated significantly higher in diagnostic and aesthetic quality than those acquired using the high kVp-low mAs strategy.
