Imaging tinnitus
Tinnitus is a common sensation with a reported prevalence of 7-32%. The British National Study of Hearing recorded that 10% of adults suffered from prolong spontaneous tinnitus, and approximately a quarter of these are subsequently referred to hospital for investigation...Imaging in hyperparathyroidism
Following their caudal migration at eight weeks of development, the parathyroid glands normally locate posterolaterally to the upper pole of the thyroid gland at the level of the cricoid cartilage (superior parathyroid glands arising from the fourth branchial pouch and...
RadCases Head and Neck Imaging
This is one of a series of books published by Thieme which are written for trainees in radiology. The depth and breadth would suit a higher-level trainee with an interest in head and neck imaging coming up to exit examinations...

Benign sinonasal growths are incredibly common, and malignant sinonasal growths thankfully rare. We know that malignant tumours often present late, and the imaging can sometimes be misleading, so the authors here compare using diffusion weighted imaging (DWI), dynamic contrast enhanced...
Imaging and embolisation of paragangliomas
Paragangliomas are rare tumours within the head and neck and any article which succinctly jogs the memory with respect to their existence and subsequent accurate diagnosis is welcome. This article concisely explains the imaging techniques used to diagnose these tumours...

Brain tumor, Choosing wisely, Ethics, Headache, Neurosurgery, Rationing, Value
Over-imaging is one of the banes of modern medicine. One may argue that in this litigious atmosphere it is safer to get an MRI done rather than not. Despite the recommendations of the American Headache Society and the American College...
The future: brain imaging for aphasia rehabilitation
1 July 2018
| Anna Volkmer
Technology offers our patients vast potential, yet the research literature in this area is often technical and difficult to translate to the day-to-day clinical setting. This article aims to review structural and functional imaging methods and discuss how they are...
The evolution and advancements in radiological imaging of the sinuses
Computed tomography (CT) imaging is crucial in the planning of any endoscopic sinus operation; we hear from one of the pioneers of CT scanning who worked with Stammberger and Messerklinger in developing many of the technologies that we now take...
