MR and US Elastography for Fibrosis Assessment in Children

April 25, 2024

Broadcasted Live and Online 12:00 noon–1:00 pm, Eastern Time 
Moderator: Jonathan Dillman, MD, MSc
Speakers: Suraj Serai, PhD and Giovanna Ferraioli, MD

Quantitative MRI and ultrasound biomarkers of liver fibrosis have become important tools in the diagnosis and clinical management of children with chronic liver disease (CLD). In particular, MR elastography is now routinely performed in clinical practice to evaluate the liver for fibrosis. Ultrasound shear-wave elastography has also become widely performed for this purpose, due to its portability and lower equipment cost. These noninvasive methods are increasingly used to replace liver biopsy for the diagnosis, quantitative staging, and treatment monitoring of patients with CLD. Elastography assesses the stiffness of the liver that is directly and strongly related to liver fibrosis. However, there are several factors that may lead to an increase of liver stiffness independently from liver fibrosis, and these are confounding factors when stiffness is used as a biomarker of fibrosis. It must be noted that this unique behavior of stiffness could be an advantage rather than a limitation, particularly in the pediatric population in whom liver disease is often due to an intricate interplay of several factors.

Join Suraj Serai, PhD and Giovanna Ferraioli, MD for a discussion and review of their AJR article. They will present practical approaches for adapting and optimizing these methods in children, with consideration of clinical indications, patient preparation, equipment requirements, acquisition technique, as well as pitfalls and confounding factors. In addition, guidance is provided for interpretation and reporting, and representative case examples are presented.

PI-RADS Upgrading Rules

May 22, 2024

Broadcasted Live and Online 12:00 noon–1:00 pm, Eastern Time 
Moderator: Nicola Schieda, MD
Speakers: Leonardo Kayat Bittencourt, MD, PhD

PI-RADS incorporate rules by which ancillary sequence findings upgrade a dominant score to a higher final category. Evidence on the upgrading rules' impact on diagnostic pathways remains scarce. Disregarding PI-RADS upgrading rules reduced net clinical benefit of the risk-based MRI-directed diagnostic pathway when considering tradeoffs between csPCa detection and biopsy avoidance. This study supports the application of PI-RADS upgrading rules to optimize biopsy selection, particularly in risk-based pathways.

Join Leonardo Kayat Bittencourt, MD, PhD for a discussion of this AJR article, which reviews the PI-RADS upgrading rules for Category 3 PI-RADS lesions and evaluates the clinical net benefit of the PI-RADS upgrading rules in MRI-directed diagnostic pathways.

Learning Outcomes

  1. Evaluate the clinical net benefit, in terms of csPCa detection and biopsy avoidance, of the PI-RADS upgrading rules in MRI-directed diagnostic pathways.
  2. Review the PI-RADS upgrading rules for Category 3 PI-RADS lesions.
