Is there a need for magnetic resonance imaging six-month post-radiosurgery for vestibular schwannoma?

With advances in imaging and radiation technologies, small, slowly growing vestibular schwannomas (VS) are treated primarily with either observation or stereotactic radiosurgery (SRS). Routine magnetic resonance (MRI) scans with gadolinium are obtained six months and one year after SRS in...

Which technique is better for cholesteatoma surgery?

There continues to be debate over the benefits and limitations of different techniques for cholesteatoma surgery. This retrospective review of 132 cases over a 10 year period with primary cholesteatoma from Turkey tried to establish which technique [canal wall up...

Which scan for children with bilateral sensorineural hearing loss? Keeping the debate going…

There have been years of debate about the appropriate imaging strategy for children with bilateral sensorineural hearing loss. For those children undergoing cochlear implant surgery, CT may provide some assistance to surgical planning, although this is not necessary in children...

Neuroimaging WG3. Neuroimaging as a window on the heterogeneity of tinnitus

Pim van Dijk and Sven Vanneste describe the hope that brain imaging techniques used for research will provide a better understanding of the heterogeneity of tinnitus through large-scale analysis. Their project will create a procedure whereby researchers can submit their...

Endolymphatic duct, a bit more than what meets the eye

It is theorised that the endolymphatic duct (ED) and the endolymphatic sac (ES) system play a role in both the production and absorption of endolymph. This system could be responsible for development of endolymphatic hydrops (EH). Recently, the presence of...

Measuring radiation fibrosis in patients with head and neck cancer

People treated with radiotherapy for head and neck cancer experience several acute and chronic effects of this treatment, of which fibrosis is perhaps the most common. Fibrosis occurs as a wound healing response and leads to scarring and reduced range...

Talk your brain well: discourse training to fortify your cognitive functioning and protect against dementia

Mild cognitive impairment (MCI) can be described as a transitional stage prior to a diagnosis of dementia. Approximately 15% of people with amnestic MCI (where memory is the leading symptom) develop dementia. Nonpharmacological interventions, specifically cognitive training, has shown some...

Is bone scanning still of value?

This is an article from Australia of 109 patients, 83 of which had CT, 72 MRI and the presence of bone invasion on imaging was compared with the histopathology. Bone invasion was present in 44 of 109 resection specimens. Bone...

To scan or not to scan?

This comprehensive review article seeks to establish how useful is MRI in the evaluation of patients with a history of smell loss or distortion. Interestingly, while some studies found the imaging unhelpful, one paper described found a 25% rate of...

Transverse venous sinus stenosis – a risk factor for CSF leak in patients with idiopathic intracranial hypertension

This was a multicentre (six French tertiary hospitals) retrospective case-controlled study aiming to investigate the rate of transverse venous sinus stenosis (TVSS) in patients with idiopathic intracranial hypertension (IIH) with nasal cerebrospinal fluid (CSF) leaks. They compared the preoperative MRI...
