Radiographers' perceptions on the quality of managing general radiographic paediatric examinations through the use of a reflective tool.

Introduction: Paediatric patients are a vulnerable population that require additional care by healthcare professionals. Quality managing these examinations ensures that effective and quality care is provided to individual patients, whilst encouraging consistency within the medical imaging department. This study explored radiographers' perspectives on quality management strategies of general radiographic paediatric examinations using a paediatric imaging reflective checklist.

Computer assisted diagnosis of Alzheimer's disease using statistical likelihood-ratio test.

The purpose of this work is to present a computer assisted diagnostic tool for radiologists in their diagnosis of Alzheimer's disease. A statistical likelihood-ratio procedure from signal detection theory was implemented in the detection of Alzheimer's disease. The probability density functions of the likelihood ratio were constructed by using medial temporal lobe (MTL) volumes of patients with Alzheimer's disease (AD) and normal controls (NC).
