To explore the value of Diffusion kurtosis imaging (DKI) metrics in the differential diagnosis of meningioma. ⋯ DKI metrics may be used to differentiate benign from malignant meningioma, and also to distinguish some histological subtypes of meningioma. Moreover, DKI metrics may potentially reflect cellular proliferation.

The objective of the present study was to comparatively evaluate the oropharyngeal space of patients with obstructive sleep apnea syndrome (OSA) and asthma by means of Cone Beam Computed Tomography (CBCT) images. ⋯ The condition of OSA+asthma was associated with a substantial reduction in upper airway measurements in comparison to controls.

Osteitis pubis in professional football players: MRI findings and correlation with clinical outcome.
Osteitis pubis (OP), a common pathology in elite athletes, is an aseptic inflammatory process of the pubic symphysis bone, and may involve surrounding soft tissues, tendons and muscles. OP is typically characterized by (often recurring) groin pain and is an important cause of time-off from sports activity in athletes. Aim of this retrospective study was to analyze magnetic resonance imaging (MRI) findings in professional football players with clinical diagnosis of OP and to correlate MRI findings with clinical outcome. ⋯ Edema in periarticular soft tissues, edema with extension to the muscles located around the symphyseal joint, as well as higher normalized signal intensity values in bone marrow edema on STIR sequences in the pubic bones at the beginning of groin pain are the most reliable MRI findings of a poor clinical long-term outcome of OP in professional football players and should be regarded as negative prognostic factors.

Dilatation of the pulmonary artery and right ventricle on chest computed tomography images is often observed in patients with pulmonary hypertension. The clinical significance of these image findings has not been defined in chronic thromboembolic pulmonary hypertension. We investigated whether the pulmonary arterial and right ventricle dilatation was associated with poor outcome in chronic thromboembolic pulmonary hypertension. ⋯ Main pulmonary arterial to ascending aortic diameter ratio measured using enhanced CT images was associated with the risk for first clinical exacerbation, and right ventricular to left ventricular diameter ratio was associated with the risk for poor prognosis in inoperable chronic thromboembolic pulmonary hypertension.

By 2050 it is projected that 115 million people worldwide will have Alzheimer's Disease (AD) [1]. Recent attempts have been made to redefine the diagnostic criteria of AD to include markers of neurodegeneration - measurable by FDG-PET - and markers of amyloid accumulation - measurable by amyloid-PET. ⋯ Both techniques have been shown to detect AD with high sensitivity and specificity compared to other neurodegenerative processes and cognitively normal age-matched individuals. However, future studies with standardised, uniform thresholds and a lengthier longitudinal follow-up need to be conducted to allow us to make surer conclusions about the future role of PET in clinical practice. In addition, comparison with post-mortem diagnosis, rather than clinical diagnosis with its acknowledged flaws, would result in more powerful statistical outcomes - which is becoming increasingly important given that several disease-modifying AD drugs are now in phase 3 trials.
