Magnetic resonance imaging of COVID-19 anosmic patients reveals abnormalities of the olfactory bulb: Preliminary prospective study.

• COVID-19 patients with total loss of smell have more olfactory bulb abnormalities at the magnetic resonance imaging than patients without loss of smell. • The olfactory bulb MRI abnormalities may be objectified through a signal intensity ratio measurement that is calculated between the average signals of the olfactory bulb and the frontal white matter. • The loss of smell is probably due to olfactory bulb inflammation related to virus spread.

Parotitis-Like Symptoms Associated with COVID-19, France, March-April 2020.

We report the clinical features of 3 patients in France who had parotitis (inflammation of the parotid salivary glands) as a clinical manifestation of confirmed coronavirus disease. Results from magnetic resonance imaging support the occurrence of intraparotid lymphadenitis, leading to a parotitis-like clinical picture.

Cardiac magnetic resonance for assessment of cardiac involvement in Takotsubo syndrome: Do we still need contrast administration?

Background: This study evaluated the ability of T1 and T2 mapping cardiovascular magnetic resonance to assess myocardial involvement in Takotsubo syndrome (TTS). We hypothesized that non-contrast mapping techniques can be accurate and sufficient.

Methods: We prospectively analysed 30 patients with TTS and 34 controls.
