| Alex McClanahan, MD (resident) | Automated Image Guidance for Endovascular Brain-Computer Interface Placement | Intervention Radiology | Funded by Radiology resident research seed grant | This project aims to develop and validate automated software for segmenting cerebral venous structures from MRI/CT and coregistering them to fluoroscopic images, enabling precise overlay of target markers on the superior sagittal sinus (SSS) for endovascular brain-computer interface (BCI) placement | |
| Xiawei Ou, phD | Maternal Obesity and Offspring Neurodevelopment: the MOON study | pediatric neuroradiology | NIH funded study at Arkansas Children's Hospital | looking for residents or students to be trained and work on neuroimaging data analysis | The goal is to evaluate how maternal obesity potentially impact offspring brain structural and functional development using advanced MRI |
| Xiawei Ou, PhD | HEALthy Brain and Child Development: the HBCD study | pediatric neuroradiology | NIH funded study at Arkansas Children's Hospital | Looking for students who can contribut to data collection (late night MRIs) | This is a national consortium study. We are collaborating with 24 other sites in the country for this longitudinal study which will follow ~6,000 mother/child dyads from pregnancy to school age, |
| Xiawei Ou, PhD | Peanut Consumpition and Brain Development | pediatric neuroradiology | USDA funded study at Arkansas Children's Hospital | looking for residents or students to be trained and work on gut microbiota and neuroimaging data analysis | This study investigates relationships between peanut consumtion during pregnancy and in early childhood and brain development and neurodevelopmental outcomes in children |
| Kumar Shashi, MD | Arteriovenous Malformations as Neoplastic-like Lesions: Molecular Underpinnings and Implications for the Interventional Radiologist | Pediatric IR | Manuscript written and under review by co-authors | This review reframes arteriovenous malformations as oncogene-driven neoplastic-like lesions and argues that the embolization procedure offers a unique opportunity for draining vein liquid biopsy to guide mutation-matched targeted therapy | |
| Kumar Shashi, MD | Percutaneous Drainage of Pneumatoceles in Neonates: A Single-Center Case Series | Pediatric IR | Awaiting IRB review | Writing up the largest reported case series of image-guided percutaneous pigtail catheter drainage of neonatal pneumatoceles, demonstrating that intervention achieves rapid resolution in days compared to the weeks-to-months expected with conservative management, in a population where watchful waiting was no longer clinically viable. | |
| Kumar Shashi, MD | Pediatric Venous Thrombectomies | Pediatric IR | IRB done, Data collection going on | Might need a student to write up the manuscript | Understanding the characteristics, management approaches, and outcomes of these patients in our institution to help refine future clinical decision-making and identify gaps in current practice patterns. |
| Kumar Shashi, MD | Image-Guided Percutaneous Thyroid Ablation in the Pediatric Population: A Systematic Review | Pediatric IR | Awaiting PROPERO registration. Literature search with librarian going on under Embase/CENTRAL syntax databases | Might need a student to write up the manuscript | This is a PRISMA-compliant systematic review evaluating the efficacy and safety of image-guided percutaneous thyroid ablation (radiofrequency, microwave, laser, and ethanol ablation) in pediatric patients under 20 years of age, a topic for which no dedicated systematic review or society guideline currently exists |
| Kumar Shashi, MD | Curved Needle Single-Stick Technique for Pediatric Tunneled Jugular CVCs: Outcomes Stratified by Catheter Type | Pediatric IR | IRB exemption done. Data collection going on | Need a resident or a student for data collection | A retrospective single-institution study describing a curved needle single-stick technique for pediatric tunneled jugular central venous catheter placement and reporting catheter-subtype-stratified technical outcomes, patency, and complication rates, not previously described in the literature. |
