To evaluate the value of morphometric analysis and perfusion-weighted magnetic resonance imaging (MRI) in differentiating solitary metastases from high-grade gliomas. ⋯ Measuring the oedema: mass and rCBV ratios of the oedema surrounding the tumour prior to operation in solitary masses proved to be useful for differentiating metastases from high-grade gliomas.

To assess the effect of changing from an "appointment" to a "same-day" ultrasound (US) service on referral pattern, departmental workload, and patient satisfaction. ⋯ There is a demand from GPs for same-day US, and it is feasible in a large hospital with flexible radiology working and increased sonographic staffing. Unless adjacent hospitals offer a similar service, continuing rise in demand could overwhelm the service.

To evaluate the role of computed tomography (CT) in needle placement for ganglion impar blocks, and to determine the efficacy of CT-guided ganglion impar blocks in the management of coccydynia. ⋯ CT can be used as an imaging method to identify the ganglion and guide the needle in ganglion impar blockade. The advantages of CT-guided injection over those performed under fluoroscopy may include accurate and confident needle placement in the sacro-coccygeal region, ease of wide area coverage, lesser risk of complications due to inadvertent injections into the major pelvic structures, and increased likelihood of reaching the ganglion impar, especially in cases with anatomical variation in the ganglion impar location. These factors may have implications in the overall success rate of ganglion impar blockade.
