3DUS as an alternative to MRI for measuring renal volume in children with autosomal dominant polycystic kidney disease.

Background: Total kidney volume, measured by magnetic resonance imaging (MRI), is a validated disease progression marker in adults with autosomal dominant polycystic kidney disease (ADPKD). However, in childhood, MRI is burdensome, explaining the need for alternatives.

Methods: Kidney volume (KV) was evaluated in 30 children with ADPKD, using three-dimensional ultrasound (3DUS), applying the ellipsoid method and manual contouring (KV KV respectively); manual contouring on MRI (KV), and the ellipsoid method on two-dimensional ultrasound (2DUS, KV).

Objective assessment of swallow function in children with suspected aspiration using pharyngeal automated impedance manometry.

Objectives: The purpose of the present study was to apply a new method, pharyngeal automated impedance manometry (AIM), as an objective assessment tool of swallow function relevant to aspiration, in a cohort of paediatric patients with dysphagia.

Methods: We studied 20 children (mean age 6 years [5 months to 13.4 years]) referred for videofluoroscopy to assess aspiration risk with simultaneous manometry-impedance.

A novel method for the nonradiological assessment of ineffective swallowing.

Objectives: This validation study evaluates a new manometry impedance-based approach for the objective assessment of pharyngeal function relevant to postswallow bolus residue.

Methods: We studied 23 adult and pediatric dysphagic patients who were all referred for a videofluoroscopy, and compared these patients with 10 adult controls. The pharyngeal phase of swallowing of semisolid boluses was recorded with manometry and impedance.

T2 quantifications of lungs in the fetal lamb with experimentally-induced congenital diaphragmatic hernia.

Objective: As an aid to evaluate lung hypoplasia, we investigated the difference between T2 value in fetal lungs of lambs with surgically-induced left-sided diaphragmatic hernia (DH) and gestational age (GA)-matched control littermates (normal [NL]).

Methods: Lungs were divided into two groups: DH (n = 4) and NL (n = 6). DH was induced at 65-75 days GA (term = 145 days).

Fetal magnetic resonance imaging of an intracranial venous thrombosis. Case report.

Objective: To describe the magnetic resonance imaging findings of an antenatal intracranial venous thrombosis.

Methods: Prenatal ultrasound (US) at 22 weeks' gestational age (GA) in a 27-year-old patient (G2 P1) revealed a nonspecific avascular echogenic mass above the cerebellum evaluated with MRI at 23 weeks' GA.

Results: With MRI an enlarged occipital pericerebral space with a layered ovoid mass at the torcular herophili was demonstrated and MRI characteristics suggested a subacute cloth.
