ReviewMagnetic resonance imaging of intramedullary spinal cord lesions: a pictorial review.
Magnetic resonance imaging (MRI) is the modality of choice for the investigation of intramedullary lesions of the spinal cord. A wide variety of conditions may result in similar imaging findings on MRI, and it is essential that the reporting radiologist have a detailed understanding of spinal cord anatomy, the pertinent imaging features of specific intramedullary lesions and the typical clinical presentation of those conditions to aid clinicians to make a prompt diagnosis. This pictorial essay discusses the clinical features and MRI appearance of a number of intramedullary conditions, which can be broadly categorised as congenital, demyelinating, vascular, neoplastic or infectious, and highlights their differentiating features.

Meta AnalysisMeta-analysis of diagnosis of liver metastatic cancers: comparison of (18) FDG PET-CT and gadolinium-enhanced MRI.
We performed a meta-analysis to compare the performance of 18F-fluorodeoxyglucose ((18) FDG) positron emission tomography-CT (PET-CT) with that of gadolinium-enhanced MRI for the detection of liver metastatic cancers. ⋯ Both (18) FDG PET-CT and gadolinium-enhanced MRI have excellent diagnostic performance for the detection of liver metastatic cancer.

Micro-bubble transcranial Doppler ultrasound for exclusion of right-to-left circulatory shunts: why should we provide the service?
Micro-bubble transcranial Doppler ultrasound is a study used for the identification and quantification of a right-to-left circulatory shunt which can be implicated in stroke. It is an underused technique in many centres. ⋯ Published literature also suggests almost perfect concordance with transoesophageal echocardiography and potentially greater sensitivity. We believe there is a great potential for neuroradiologists to provide this service as part of the diagnostic workup in patients with cryptogenic stroke.

Randomized Controlled Trial Comparative StudyStereoscopy in diagnostic radiology and procedure planning: does stereoscopic assessment of volume-rendered CT angiograms lead to more accurate characterisation of cerebral aneurysms compared with traditional monoscopic viewing?
Stereoscopic vision is a critical part of the human visual system, conveying more information than two-dimensional, monoscopic observation alone. This study aimed to quantify the contribution of stereoscopy in assessment of radiographic data, using widely available three-dimensional (3D)-capable display monitors by assessing whether stereoscopic viewing improved the characterisation of cerebral aneurysms. ⋯ Stereoscopy has a long history, but it has only recently become technically feasible for stored cross-sectional data to be adequately reformatted and displayed in this format. Scant literature exists to quantify the technology's possible contribution to medical imaging - this study attempts to build on this limited knowledge base and promote discussion within the field. Stereoscopic viewing of images should be further investigated and may well eventually find a permanent place in procedural and diagnostic medical imaging.

Electrolytic echo enhancement: a novel method to make needles more reflective to ultrasound.
This study examines the effect of augmenting the ultrasound reflectivity of needles using a novel electrolytic echo enhancement method. ⋯ Electrolytic echo enhancement has the potential to make ultrasound-guided procedures safer and quicker for patients and increase the confidence of operators in their ability to see the whole needle including its tip.
