Background: In patients with tracheobronchial involvement, the differential diagnosis between granulomatosis with polyangiitis (GPA) and relapsing polychondritis (RP) can be challenging. The aim of this study was to describe the characteristics of airway abnormalities on chest computed tomography (CT) in patients with GPA or RP and to determine whether specific imaging criteria could be used to differentiate them.
Methods: GPA and RP patients with tracheobronchial involvement referred to a national referral center from 2008 to 2020 were evaluated.
Objectives: To evaluate the diagnostic and prognostic performance of CT in patients referred for COVID19 suspicion to a French university hospital, depending on symptoms and date of onset.
Methods: From March 1st to March 28th, 214 patients having both chest CT scan and reverse transcriptase polymerase chain reaction (RT- PCT) within 24 h were retrospectively evaluated. Sensitivity, specificity, negative and positive predictive values of first and expert readings were calculated together with inter reader agreement, with results of RT-PCR as standard of reference and according to symptoms and onset date.
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.
