INTRODUCTION: Multi-slice computed tomography (MSCT) is an accurate tool for the assessment of left ventricular ejection fraction (LVEF). However, in order to reduce radiation dose, prospective acquisition protocols are currently used, in which the end-systole and end-diastole are not scanned. Our aim was to study the accuracy of the assessment of LVEF using fixed late-systolic and mid-diastolic cardiac phases compared with echocardiography. METHODS: MSCT-derived LVEF was measured with off-line commercially available software packages, and compared with echocardiography-derived LVEF using the Simpson's method...

INTRODUCTION: Ultrasound (US) has an important role in musculoskeletal (MSK) evaluation, allowing the study of muscle morphology and function. Muscle thickness (MT) and muscle echo-intensity (EI) are two important parameters that may quantify muscle structural adaptations to a variety of stimuli. The aim was to explore the potential of quantitative US imaging for assessing the adaptations and responses of the muscle tissue to increased contractile activity using B-mode US. This study was centred on the quadriceps femoris muscle contractile activity on MT and EI...

OBJECTIVES: To evaluate the current evidence for whether Fracture Liaison Services are being utilised effectively in the UK to aid in the prevention of fragility fractures. KEY FINDINGS: Radiological under-reporting and non-standardised assessment of fragility fractures still persist, with low numbers of patients undergoing a risk assessment and treatment for secondary prevention of fracture. In order to improve care for these patients, the reporting of vertebral fractures must be improved and standardised in order to identify patients at increased risk of secondary fragility fractures...

INTRODUCTION: Optimization of image quality and patient radiation dose is achieved in part by positioning the patient at the isocenter of the CT gantry. The aim of this study was to establish whether there was increased isocenter misalignment (IM) in CT colonography (CTC) scans by comparing patient position during the prone part of a CTC to patient position during renal stone protocol CT (CT-KUB) and patient position during the supine part of a CTC to patient position during abdominopelvic CT (CT-AP)...

BACKGROUND: In projection radiography, lead rubber shielding has long been used to protect the gonads both within and outside the collimated field. However, the relative radio-sensitivity of the gonads is considered lower than previously, and doses from digital projection radiography are reported as being lower than in previous eras. These factors, along with technical difficulties encountered in placing lead shielding effectively, lead to varied opinions on the efficacy of such shielding in peer reviewed literature...
