How reliable is non-echoplanar diffusion-weighted MRI in picking up postoperative cholesteatoma in children?
Cholesteatoma occurs more often in children than in adults and is more aggressive, often resulting in ossicular erosion and marked conductive loss, amongst other more serious possibilities. Recurrence happens in all three methods used, namely canal wall up, canal wall...
Diagnostic performance of non-echo-planar diffusion weighted MRI in detection of suspected cholesteatoma
Even though a ‘second look’ remains a gold standard for detection of residual cholesteatoma after intact canal wall techniques, non-echo-planar diffusion weighted MRI is considered a reasonable alternative to avoid further surgery. However, to establish or exclude a cholesteatoma de...
New MRI technique assesses treatment response in skull base osteomyelitis
This paper describes another useful imaging technique to monitor Necrotising Otitis Externa (NOE). Echoplanar diffusion weighted magnetic resonance (DW MR) shows high signal on the ‘ADC map’ with active disease and this reduces in signal intensity as symptoms improve. This...
Pulsatile tinnitus, one more piece in the jigsaw
Pulsatile tinnitus (PT) is a common ENT symptom. It can generally be divided into venous and arterial. Arterial PT might be investigated with a CT scan while a venous one with an MRI or an MRV (MRI Venogram). Anecdotally, arachnoid...
Facial nerve anatomy in the temporal bone
Knowledge of the facial nerve anatomy during otological surgery is crucial in avoiding an iatrogenic injury to the facial nerve. In this study, the authors investigated the anatomical relationship between the tympanic portion of the facial canal (FC) and the...
Are imaging studies necessary in uncomplicated headaches?
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
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...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...
Implantable devices and large magnets – do they mix well?
Although all brands are MRI safe at 1.5 T, the active middle ear implant system Vibrant Soundbridge (VSB), is special since it houses two magnets. These include a magnetic floating mass transducer (FMT) and an audioprocessor fixing receiver magnet which...
Should we be doing earlier MRIs in sudden sensorineural hearing loss?
There is recognised variation between ENT departments in exact imaging protocols for the workup of idiopathic sudden sensorineural hearing loss (ISSNHL) but a routine MRI to exclude retrocochlear pathology is standard, usually following immediate treatment with oral +/- intratympanic steroids....
An advance in imaging for sinonasal tumours?
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...
