The role of locoregional therapy options (percutaneous thermal ablation, chemoembolization, and/or radioembolization) continues to gain traction in the pediatric oncology world, particularly with the management of primary and metastatic liver lesions. Post-treatment imaging of the liver must clearly differentiate between treatment response, residual untreated disease and progressive disease in order to guide the future therapeutic options. The post-treatment imaging appearance of pediatric liver lesions can be affected by multiple factors (tumor type, tumor vascularity, radiation vs non-radiation therapy, background liver characteristics, time lapse from the interventional oncology procedure, imaging technique, e.g.). The understanding and interpretation of such factors continues to evolve, as seen with the most recent ACR LI-RADS Treatment Response Assessment Update in 2024. This case cohort presents illustrative examples from multiple pediatric interventional oncology programs, using various imaging modalities to demonstrate post-treatment liver imaging findings following locoregional therapy for both primary and metastatic liver lesions in pediatric patients.

Inguinal lymph node identification using ultrasound is critical in performing intranodal lymphangiography. We routinely utilize a 15 MHz “hockey stick” linear high resolution ultrasound probe (Philips Epic 7) for identification as well as to gain needle access into the inguinal lymph node. However in children with severe body wall edema and in low weight premature babied identification of lymph nodes can be difficult and sometimes impossible. Higher frequency ultrasound transducers offer the potential for improved identification of lymph nodes in such cases. The aim of this study was to compare imaging finding of high resolution US probe to the traditional 15 mHz probe in patients undergoing lymph node access for lymphangiography. Read More

Percutaneous interventions are increasingly being performed under MR-guidance due to the absence of ionizing radiation, the ability to visualize target lesion and the capability to monitor real-time treatment effect. Here we outline our experience with developing an interventional MRI (iMRI) service at a pediatric institution. Read More

Contrast-enhanced ultrasound (CEUS) and shear wave elastography (SWE) have been widely studied in adult thyroid disease. However, evaluation of thyroid nodules using these tools in pediatric patients has yet to be published. We aim to evaluate the feasibility and safety of CEUS and SWE for thyroid nodules in children at the time of cytologic biopsy. Read More

Percutaneous lymphatic interventions (PLI) target the pulmonary lymphatic abnormalities seen in patients with plastic bronchitis (PB). Existing data in patients with congenital heart disease(CHD)indicates poor transplant-free survival after the diagnosis of PB. We describe various techniques of PLI and characterize intermediate-term survival and complications after PLI. Read More

Little is known about how families of children undergoing interventional radiology (IR) procedures experience their interactions with IR teams; therefore, we conducted a qualitative study to explore and learn from families experience with IR teams in order to educate pediatric IR staff and ultimately improve delivery of care.

Implantable Venous Access Devices (IVAD) play an important role in medical treatment and comfort to pediatric patients requiring long term intravenous therapy. Traditionally, 2 small surgical skin incisions are utilized in the procedure, one in the neck for jugular venous access and the other in the chest wall to create a subcutaneous pocket for the IVAD reservoir. The authors describe an innovative technique, where a long-curved needle and curved guidewire are utilized to obtain internal jugular vein access through a single chest wall incision for both vascular access and the IVAD reservoir. The subcutaneous tract and the venous access sites are serially dilated and the IVAD is placed over the wire. This technique avoids the incision placed at the neck. This modification has multiple potential advantages, as it avoids a second incision in at risk patients (tracheostomy, anasarca, cervical instability), potential better cosmetic outcome and potentially lower risk of infection,. The purpose of this educational abstract is to demonstrate this innovative minimally invasive technique of placing IVAD in pediatric population. Read More
