Safe use of contrast media in myasthenia gravis: systematic review and updated European Society of Urogenital Radiology Contrast Media Safety Committee guidelines
ConclusionsThere is limited evidence on the relationship between CM and myasthenia gravis symptoms. In the vast majority of myasthenia gravis patients, CM are safe. Probably, in less than 5% of the patients, iodine-based CM administration may lead to increased severity of the symptoms within the first 24 h after administration.Clinical relevance statementBe aware that intravenous administration of iodine-based contrast media can lead to an increase of symptoms in patients with myasthenia gravis within the first 24 h. This can probably happen in less than 5% of the patients.Key Points• It is unclear whether modern con...

White matter hyperintensities in cholinergic pathways correlates of cognitive impairment in moyamoya disease
ConclusionsThe damage of cholinergic pathways caused by WMHs plays an independent effect on cognition and CHIPS could be a useful method in identifying MMD patients likely to be cognitive impairment.Clinical relevance statementThis study shows that Cholinergic Pathways Hyperintensities Scale (CHIPS) could be a simple and reliable method in identifying cognitive impairment for patients with moyamoya disease. CHIPS could be helpful in clinical practice, such as guiding treatment decisions and predicting outcome.Key Points• Cholinergic Pathways Hyperintensities Scale was significantly associated with cognitive screening tes...

Optic nerve thickening on high-spatial-resolution MRI predicts early-stage postlaminar optic nerve invasion in retinoblastoma
ConclusionPostlaminar optic nerve thickening can predict early-stage postlaminar optic nerve invasion in retinoblastoma.Clinical relevance statementThis study provides an additional tool for clinicians to help determine postlaminar optic nerve invasion, which is a risk factor for developing metastatic disease in retinoblastoma patients.Key Points• The diagnostic accuracy of contrast-enhanced MRI for detecting postlaminar optic nerve invasion is limited in retinoblastoma patients.• Optic nerve thickening can predict postlaminar optic nerve invasion.• A prediction model combining MRI features has a high sensitivity and...

Prediction of acute rejection in renal allografts using shear-wave dispersion slope
ConclusionShear-wave dispersion slope obtained at SWE may help identify renal allograft dysfunction.Clinical relevance statementAcute rejection in renal allografts is a major cause of allograft failure, but noninvasive diagnosis is a challenge. Shear-wave dispersion slope can identify acute rejection non-invasively.Key Points•The interstitial fibrosis and tubular atrophy grade was a determinant factor for stiffness ratio and shear-wave dispersion slope ratio between cortex and renal sinus fat.•Shear-wave dispersion slope ratio between cortex and renal sinus fat could identify acute rejection in renal allografts.•A sh...
