Ultrasound and MRI of the foot in children and adolescents newly diagnosed with juvenile idiopathic arthritis.

Aim: To evaluate the spectrum of inflammatory features in foot joints which may be detected on routinely performed ultrasound (US) and magnetic resonance imaging (MRI) in children newly diagnosed with juvenile idiopathic arthritis (JIA).

Material And Methods: Two groups of children hospitalized in a reference center for rheumatology, newly diagnosed with JIA and suspected of foot involvement in the course of JIA were included in this retrospective study. In the first group of 47 patients aged 1-18 years, the imaging was restricted to US.

Foot and Ankle Conventional Radiography in Juvenile Idiopathic Arthritis: Does It Still Matter?

Objectives: The aim of this study was to evaluate the residual value of Conventional Radiography in children with arthralgia clinically suspected of Juvenile Idiopathic Arthritis (JIA).

Materials And Methods: Three hundred seventy-two patients aged 1-18 years suspected of JIA were retrospectively reviewed. All patients had foot and ankle plain films performed in standard two projections: ankle in antero-posterior and lateral, and foot in antero-posterior and oblique.

People living with HIV have low trabecular bone mineral density, high bone marrow adiposity, and poor trabecular bone microarchitecture at the proximal femur.

Unlabelled: People living with HIV (PLWH) have increased risk of osteoporosis and fractures. We assessed the proximal femur of PLWH and age-matched seronegative controls using quantitative computed tomography and magnetic resonance imaging. Results suggest that the trabecular compartment is compromised at fracture-prone regions in the proximal femur of PLWH.

Ankle Magnetic Resonance Imaging in Juvenile Idiopathic Arthritis Versus Non-Juvenile Idiopathic Arthritis Patients with Arthralgia.

This retrospective case-control study aimed to evaluate whether Magnetic Resonance Imaging (MRI) enables differentiation of ankle arthritis in Juvenile Idiopathic Afrthritis JIA from ankle arthralgia of unknown aetiology in patients clinically suspected of JIA. Forty-four children, at ages 5-16, who underwent MRI of the ankle from January 2016 to March 2021 for clinically suspected active ankle arthritis in the course of JIA were included. MRI findings in both groups-patients with the final diagnosis of JIA and without final diagnosis of JIA-were compared and scored.

Radiographs and MRI of the Cervical Spine in Juvenile Idiopathic Arthritis: A Cross-Sectional Retrospective Study.

Background: Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease among children. In some patients, cervical spine arthritis remains a serious and chronic manifestation of JIA. The aim of this study was to assess the frequency of cervical spine lesions on radiographs and MRI in JIA patients with clinical signs of cervical spine involvement and to verify if with the addition of MRI, the use of radiographs could be abandoned.
