MR enterography grading of pediatric ileocolonic Crohn disease activity based on a single bowel segment.

Background: Ileocolonoscopy with histology has been considered the gold standard for Crohn disease (CD) diagnosis and monitoring. Over the last years, magnetic resonance enterography (MRE) has become more and more popular, representing a valid non-invasive technique.

Objective: To propose a simplified MRE score, the pediatric CD magnetic resonance index (PCDMRI), based only on the most affected bowel segment, to grade active inflammation in children with CD.

Lean body weight versus total body weight to calculate the iodinated contrast media volume in abdominal CT: a randomised controlled trial.

Objectives: Iodinated contrast media (ICM) could be more appropriately dosed on patient lean body weight (LBW) than on total body weight (TBW).

Methods: After Ethics Committee approval, trial registration NCT03384979, patients aged ≥ 18 years scheduled for multiphasic abdominal CT were randomised for ICM dose to LBW group (0.63 gI/kg of LBW) or TBW group (0.

Contrast-Enhanced Ultrasound-Guided Percutaneous Biopsy of the Peritoneum: A Series of 3 Cases.

In the presence of peritoneal disease, patients often should undergo biopsy of the peritoneum for acquiring a specific pathologic diagnosis. Ultrasound is ideal for guiding peritoneal biopsy, although in some situations, it can be technically challenging. The addition of a contrast agent can improve the visualization of lesions and adjacent organs, providing radiologists increased confidence.
