Re: Assessment of interpretation of paediatric skeletal radiographs in the emergency room
Sir — We read with interest the recently published study by Kargl et al.1 We agree that the interpretation of skeletal radiographs in paediatric trauma can be challenging, emphasising the authors' conclusion that such imaging should be formally reported by an experienced clinical radiologist. This is particularly prudent given that, “… the initial interpretation of radiographs is often performed by physicians in training with lesser experience concerning the specifics of paediatric skeletal radiography”.

Commentary on myocardial CT perfusion imaging and atherosclerotic plaque characteristics on coronary CT angiography for the identification of myocardial ischaemia
Information about both luminal stenoses and their physiological significance is important in guiding revascularisation, but cannot be the whole story in coronary disease. Prognosis is principally determined by the risk of acute myocardial infarction, when an atheromatous plaque becomes unstable and triggers coronary thrombosis. Obstructive plaques are more vulnerable than non-obstructive ones, but the overall burden of the latter is so much greater that they account for the majority of events; however, certain adverse plaque characteristics on imaging predict an increased risk.

Commentary on: radiological diagnosis of chronic recurrent multifocal osteomyelitis using whole-body MRI-based lesion distribution patterns
At present, interpretation of the findings on whole-body magnetic resonance imaging (WBMRI) in children is by large based on the individual radiologist's personal experience and opinion, causing diverging research results and practice. The study by Andronikou et  al., in this edition of Clinical Radiology is welcome as it describes two distinct patterns of bone marrow signal change in children with chronic recurrent multifocal osteomyelitis (CRMO)/chronic non-bacterial osteomyelitis (CNO); namely tibial/appendicular involvement and clavicular/spinal involv ement.

Multiparametric (mp) prostate magnetic resonance imaging (MRI) is playing an increasingly prominent role in the diagnostic work-up of patients with suspected prostate cancer.

Virtual Special Issue: Breast shear-wave elastography: bringing colour to breast ultrasound
The routine use of shear-wave elastography (SWE) during breast ultrasound in Europe has still not occurred, as adoption has been slow particularly in the UK. At first, this may seem surprising as SWE can be used to confirm benignity of fibroadenomas. In combination with grey-scale ultrasound, SWE can reduce the number of fibroadenoma biopsies performed in symptomatic clinics. One cause of the slow adoption was that, until recently, the best SWE system was only available from a small manufacturer whose machine, in the past, had a suboptimal grey-scale imaging; however, ultrasound machines that combine excellent grey-scale a...
