To evaluate the efficacy and the complication rate of CT-guided percutaneous lung biopsy of pulmonary nodules smaller than 20 mm in diameter using a 20-gauge coaxial automated biopsy device. ⋯ The accuracy and complication rate of percutaneous CT-guided biopsy of nodules smaller than 20 mm, performed using an automated 20-gauge coaxial biopsy device, are comparable to those for larger lesions.

Consultant radiologists appear to be at greater risk of burnout than consultants working in other specialties. The aim of this study was to examine sources of stress and satisfaction at work for radiologists and hospital consultants in other specialties in order to try to understand this difference. ⋯ These data highlight aspects of radiologists' work which need to be tackled in order to reduce their stress and increase their satisfaction, and thereby their risk of burnout.

To determine the accuracy of ultrasound in the detection of pneumothorax. ⋯ In this patient group, ultrasound was more sensitive than erect chest radiography in the detection of pneumothorax. Both have a specificity of 100%. This study suggests that ultrasound may prove valuable in pneumothorax detection when rapid conventional radiography is not possible or practical, and in circumstances where ultrasound is readily available, such as during ultrasound-guided interventional procedures.

Early diagnosis of acute intracranial hypertension is essential to enable prompt, optimal treatment. The optic nerve sheath diameter (ONSD) is increased in raised ICP and there has been recent interest in the use of ultrasound to diagnose and indirectly monitor raised ICP by ONSD measurement. The advantages of the technique include its non-invasiveness, wide availability, portability, low cost and the absence of ionizing radiation. This prospective study was designed to establish the range of normal values for ONSD in infants and children up to 15 years of age. ⋯ Using the technique described here, our results suggest that an ONSD of greater than 4 mm in infants less than 1 year, and 45 mm or greater in older children, should be regarded as abnormal.
