Diffusion weighted images (DWI) have the potential to provide valuable information on the diffusion and perfusion properties of the human placenta and therefore has the capability for detection of early developmental fetal anomalies. The purpose of this study was to determine if DWI of the placenta demonstrates differences between fetuses with and without central nervous system (CNS) abnormalities. Read More

ARPKD causes diffuse microcysts in the kidney parenchyma, and cyst burden cannot be quantified by standard image segmentation methods. We sought to assess whether apparent diffusion coefficient (ADC) measured by DWI could serve as a non-invasive biomarker of ARPKD severity, with the hypothesis that ADC would be higher in cystic vs. non-cystic parenchyma due to higher extracellular water content. We examined whether ADC could distinguish healthy kidneys from those affected by ARPKD, and whether a threshold ADC value could be established to differentiate cystic vs. non-cystic parenchyma.

Diffusion weighted imaging (DWI) is used in many diverse clinical and research applications including evaluation of stroke, avascular necrosis, renal tumor classification and others. Standardizing the apparent diffusion coefficient (ADC) value across different studies and institutions has proven difficult due to change in equipment and protocols used. The aim of this electronic poster is to explain this inconsistency in ADC estimation using the pMRI (www.parametricmri.com) software package. Variability in ADC due to b-value selection, low SNR, decay model choice, and theoretical perfusion effects is explained and demonstrated by image analysis of anonymized cases. Read More

Whole-body (WB) magnetic resonance (MR) imaging in children is of special interest because it is radiation free and can be used to evaluate systemic conditions, exploiting the advantage of the superior soft-tissue contrast provided by MR imaging. An important clinical application of whole-body MR imaging in children is its use for screening of oncologic conditions, tumor characterization, and staging. However, the list of non-oncologic applications of WB MRI has recently expanded to include the evaluation of numerous multisystemic conditions.

This is a pictorial review of different oncologic applications of WB MRI including cancer predisposition syndromes, solid neoplasias and lymphomas, as well as of non-oncologic applications of WB MRI including chronic recurrent osteomyelitis (CRMO), enthesitis related arthritis (ERA), vascular malformations and benign tumors. In this review we discuss the advantages and challenges of conventional and functional MRI sequences including the use of diffusion weighted imaging (DWI), color-encoded DWI enhanced with iron supplement Ferumoxytol as blood pool contrast agent, as well as the advantages and disadvantages of the recently introduced WB positron emission tomography (PET)/MRI.
