Seizure-induced reversible magnetic resonance imaging abnormalities: A retrospective cohort study.

Purpose: Seizure-induced reversible magnetic resonance imaging (MRI) abnormalities (SRMA) present challenges in seizure management. We sought to investigate the frequency, risk factors, evolution and prognostic value of SRMA.

Methods: A retrospective observational cohort study of consecutive seizure patients investigated with an MRI of the brain was conducted.

Magnetic resonance imaging in knee synovitis: clinical utility in differentiating asymptomatic and symptomatic meniscal tears.

It is well documented that meniscal tears may be found frequently by MRI as an incidental finding in asymptomatic knees. We aim to review the literature regarding the ability of MRI to differentiate between asymptomatic and symptomatic meniscal tears. Ovid MEDLINE, MEDLINE inProcess, Cochrane reviews, Web of Science, Embase and CINAHL were systematically searched.

Are extra-labral MR findings useful in the diagnosis of a labral tear?

Objective: To determine diagnostic performance statistics of extra-labral magnetic resonance (MR) findings for detection of labral tears in a population of patients with clinical suspicion of this diagnosis.

Materials And Methods: Seventy-nine patients clinically suspected of having a labral tear (who underwent arthroscopy) had their MR studies retrospectively reviewed to determine the presence of lateral acetabular oedema-like marrow signal, ganglia, dysplastic femoral bumps, synovial herniation pits and geodes. These findings were then correlated with the arthroscopic presence (or absence) of a labral tear.

Prevalence and location of acetabular sublabral sulci at hip arthroscopy with retrospective MRI review.

Objective: The objective of this prospective study was to determine the prevalence and location of acetabular sublabral sulci diagnosed as variants at hip arthroscopy and to provide a retrospective MRI review.

Subjects And Methods: Two experienced hip arthroscopists noted the prevalence and location of acetabular labral sulci in 121 patients. The study population consisted of 57 males and 64 females with an average age of 43 years (range, 16-70 years).
