Intraoperative MRI use during pituitary tumour resection
This article provides an overview of intraoperative MRI (iMRI) use in transphenoidal surgery (TSS) for pituitary tumours. Traditionally imaging of the surgical field during surgery involves intraoperative fluoroscopic imaging or neuronavigation which help to avoid injury to critical structures but...
Should all patients with BPPV have an MRI?
This paper describes an interesting series of 500 patients over a 10-year period with posterior canal BPPV, who had been investigated with MRI. The female to male ratio was 1.6:1 with a mean age of 56. There was a right...
Gadolinium enhanced MRI and the diagnosis of Ménière’s disease
Despite various criteria applied over the years to diagnose Ménière’s disease since the concept of endolymphatic hydrops was first observed in postmortem examinations of patients in 1938, the diagnosis still remains mainly clinical. To visualise endolymphatic hydrops in MRI imaging,...
MRI in diagnosis Meniere’s disease: what is the evidence?
The utility of magnetic resonance imaging (MRI) in the diagnosis of Meniere’s disease (MD) has attracted a lot of interest recently. It is well accepted that the saccule is the most common vestibular organ affected by endolymphatic hydrops (EH) and...
Associated findings in MRI used for detecting acoustic neuroma
Presently, gadolinium enhanced magnetic resonance imaging is the ‘gold standard’ for investigating acoustic neuroma. There are often ‘incidental’ findings that may or may not be significant. In this study of 109 scans, the authors noted an uptake of 0.9% for...
Vascular loops found on MRI IAM for tinnitus
This group from the Netherlands looks at the finding of vascular loops found on MRI IAMs requested for tinnitus. It is a common finding for all who request such imaging. This work adds to the body of evidence that such...
Follow-up of NF2 patients with ABRs, SDS and MRI
Hearing loss is one of the earliest manifestations in vestibular schwannomas with 60% of the patients having high frequency loss. Several metabolic and mechanical factors influencing the cochlea and cochlear nerve have been implicated in the hearing decline noted in...
Incidental findings in paranasal sinus Magnetic Resonance Imaging (MRI) studies
Incidental findings in the paranasal sinuses of mucosal thickening and polyps in MRI studies may cause concerns for clinicians and patients. The authors studied MRIs of 982 participants with a mean age of 58.5 years who randomly and independent of...
MRI and the endolymphatic space
This is an interesting study which was performed to evaluate the endolymphatic space in patients with endolymphatic hydrops (EH), using MR imaging. Seven patients aged between 21–77 years; five female, two male with unilateral or bilateral symptoms of EH were...
Do we need contrast MRI when screening for vestibular schwannoma?
Gadolinium contrast enhanced T1-weighted (gT1w) MRI images of the internal acoustic meati have long been considered the gold standard in the diagnosis of vestibular schwannoma (VS). However, the addition of contrast to the MRI examination increases the cost and time...
MRI scanning patients with cochlear implants and auditory brainstem implants
In the last five to six decades, MRI scanning has gone from physics experiments in Nottingham University through to Nobel prize-winning work by Sir Peter Mansfield and Paul Lauterbur, to a ‘routine’ imaging modality with an estimated 60 million MRI...
