Contrast enhanced voiding urosonography (CEVUS) uses intravesically administered microbubble contrast to detect vesicoureteral reflux (VUR) and urethral anomalies with ultrasound. Multiple studies have suggested CEVUS can replace voiding cystourethrogram (VCUG) as a radiation free alternative. Analysis of ureterovesical junction (UVJ) and ureters on VCUG documenting UVJ position, ureteral duplication, periureteral diverticula and ureteroceles is important as anatomic variations may affect management and surgical approach. Our purpose was to assess UVJ region visualization in children with VUR detected on CEVUS. Read More

Fallopian tube torsion is a rare cause of acute abdominal pain in pediatric patients. Pelvic ultrasound is the first imaging modality utilized to evaluate for pelvic pathology, typically to rule out ovarian torsion. Ultrasound findings of fallopian tube torsion can be challenging, leading to delayed surgical intervention, particularly when ovaries have a normal gray scale appearance and spectral Doppler waveforms. We reviewed the ultrasound features of fallopian tube torsion in a series of surgically proven cases. Read More

Compressed SENSE (CS) facilitates significantly shorter MRI acquisition times. There is a paucity of data comparing quantitative MRI with regularly under-sampling schemes like SENSE to pseudorandom under-sampling schemes like CS. The purpose was to compare measurements of liver proton density fat fraction (PDFF), T2*, and stiffness between SENSE and CS techniques with identical MR acquisition parameters. Read More

Contrast-Enhanced ultrasound (CEUS) is being increasingly used in children as it offers the advantage over CT/MRI of real time imaging, low cost, lack of radiation, easy access, and no need for anesthesia. In our study, we evaluate CEUS for characterization of liver lesions in children and compared the enhancement patterns and diagnosis based on CEUS to MRI/CT in the pediatric population with liver lesions.

MR elastography (MRE) is increasingly being used to non-invasively assess diffuse liver disease in children. However, there are limited normal liver stiffness data for MRE in children. The purpose of this study was to determine normal liver stiffness measured by MRE for children and assess for associations with demographic factors, MRI field strength and MRI vendor. Read More

Assessment of fluid overload in hemodialysis patients is usually based on a patient’s ideal weight which presents a challenge, especially in children due to normal growth and development. Noninvasive, validated sonographic fluid balance measurements could potentially guide fluid removal in children undergoing hemodialysis. We examine changes in IVC diameter and lung b-lines in children pre- and post- dialysis. Read More

This study compares the performance of a single free-breathing GRASP sequence to a full C-MRE protocol in pediatric small bowel CD. The high k-trans of affected bowel in CD may allow high spatiotemporal GRASP dynamic contrast-enhanced technique to provide comprehensive diagnostic value in CD, especially in patients with limited breath-hold capacity.
