Simultaneous assessment of microcalcifications and morphological criteria of vulnerability in carotid artery plaque using hybrid F-NaF PET/MRI.

Background: Previous studies have suggested the role of microcalcifications in plaque vulnerability. This exploratory study sought to assess the potential of hybrid positron-emission tomography (PET)/magnetic resonance imaging (MRI) using F-sodium fluoride (F-NaF) to check simultaneously F-NaF uptake, a marker of microcalcifications, and morphological criteria of vulnerability.

Methods And Results: We included 12 patients with either recently symptomatic or asymptomatic carotid stenosis.

Association between physical activity and sedentary behaviour on carotid atherosclerotic plaques: an epidemiological and histological study in 90 asymptomatic patients.

Objective: Carotid atherosclerotic plaques are a source of emboli for stroke. 'Unstable' carotid atherosclerotic plaques may have intraplaque haemorrhages, neovessels, prevalent macrophages, excessive calcium deposits, a large lipid core and a thin fibrous cap. Regular physical activity (PA) may lower the risk of plaques becoming unstable.

Necrotizing Infundibular Crystalline Folliculitis (NICF) Induced by Anti-Tumoral Therapies: Report of 2 Cases.

Necrotizing Infundibular Crystalline Folliculitis (NICF) is rare entity of unknown pathogenesis presenting as follicular crystalline papules arising in seborrheic areas. We report 2 cases of NICF in patients under targeted therapy for metastatic adenocarcinoma. In one case, the lesions reappeared cyclically every 3 weeks after each injection and in the other case, lesions persisted until disruption of the continuous oral therapy.

[Contribution of X-ray computed tomography in the evaluation of kidney performance].

X-ray computer assisted tomography scanner is an imaging method based on the use of X-ray attenuation in tissue. This attenuation is proportional to the density of the tissue (without or after contrast media injection) in each pixel image of the image. Spiral scanner, the electron beam computed tomography (EBCT) scanner and multidetector computed tomography scanner allow renal anatomical measurements, such as cortical and medullary volume, but also the measurement of renal functional parameters, such as regional renal perfusion, renal blood flow and glomerular filtration rate.
