Liver shear wave elastography and attenuation imaging coefficient measures: prospective evaluation in healthy children.

Purpose: Ultrasonographic quantitative measurements enable characterizing the stiffness and viscosity of liver parenchyma. Normal Shear Wave Elastography (SWE) values have been reported in adults and children. The Attenuation Imaging (ATI) coefficient is a measure of local sound energy loss thought to reflect steatosis in adults.

Chronic recurrent multifocal osteomyelitis (CRMO): a longitudinal case series review.

Background: Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory disorder that is currently diagnosed based on clinical, radiologic, pathological and longitudinal findings.

Objective: To provide detailed descriptions of CRMO lesion patterns seen on radiographs and MRI and to suggest clinical use of whole-body MRI and propose noninvasive diagnostic strategy.

Materials And Methods: Retrospective longitudinal study (1989-2010) of 31 children (22 girls, 9 boys) diagnosed with CRMO.

Pineal cysts in children.

OBJECTIVE: To describe the prevalence and characteristics of pineal cysts found on MRI in children. METHODS: This is a retrospective monocentric study of all brain magnetic resonance imaging (MRI) examinations performed under the same technical conditions for checking the idiopathic nature of short stature (ISS group, n = 116) and for the investigation of central precocious puberty (CPP) over a 3-year period (n = 56). Dimensions, wall and septal thickness, number of locules, signal intensity, and the presence of a solid component were analysed.

Feasibility of dynamic MRI for evaluating velopharyngeal insufficiency in children.

Objective: To demonstrate the feasibility of dynamic MRI with near-real-time temporal resolution for analysing velopharyngeal closure.

Methods: Eleven children and young adults (seven girls, four boys, mean age: 8.4 years) with suspected velopharyngeal insufficiency (VPI), and one healthy volunteer underwent MRI (1.

[Fetal cerebral magnetic resonance imaging (MRI). Indications, normal and pathological patterns].

Fetal MRI is a specific imaging modality, always performed after a reference ultrasound examination. The decision to perform an MRI-scan must take into account the anxiety constantly generated by the need for this unusual examination during pregnancy. To date, no side-effect associated with 1.
