About the Lab
Professor Joo-Hyung Oh's research lab specializes in medical imaging and interventional radiology, with a focus on diagnostic ultrasound applications and image-guided interventions for urological, gastrointestinal, and vascular conditions. The lab investigates innovative, minimally invasive techniques such as sonographically guided needle aspiration for prostatic abscesses and explores the role of imaging in diagnosing rare conditions like nutcracker syndrome and esophageal dissecting intramural hematoma. Additionally, the lab contributes to oncology research, particularly in understanding resistance mechanisms in colorectal cancer and advancing image-based diagnostic and therapeutic strategies. The integration of advanced imaging modalities with clinical interventional approaches defines the lab’s translational research direction.

METHODS: Doppler sonographic findings in 47 children with orthostatic proteinuria and in 27 healthy control subjects were compared. The diagnosis of orthostatic proteinuria was made on the basis of clinical and laboratory findings. The peak veloc
The purpose of this study was to assess the effectiveness of transrectal ultrasonographically guided needle aspiration in the treatment of prostatic abscess. Fourteen patients with prostatic abscess were evaluated with this technique and treated with sonographically guided needle aspiration. Using this technique, all cases (100%) had one or more hypoechoic areas within the prostate that contained inhomogeneous materials; in 10 patients (71.0%), the lesion showed internal septa or solid portion.
Gastrointestinal (GI) fistulas are frequently very serious complications that are associated with high morbidity and mortality. GI fistulas can cause a wide array of pathophysiological effects by allowing abnormal diversion of the GI contents, including digestive fluid, water, electrolytes, and nutrients, from either one intestine to another or from the intestine to the skin. As an alternative to surgery, recent technical advances in interventional radiology and percutaneous techniques have been
Colorectal cancer (CRC) is the fourth most diagnosed cancer and the second leading cause of cancer-related death in the United States. Despite advancements in treatment-including chemotherapy, targeted therapy with epidermal growth factor receptor antibodies, and immunotherapy with immune checkpoint inhibitors-many CRC cases exhibit intrinsic or acquired resistance to cancer treatment, leading to limited treatment efficacy and high recurrence rates. Resistance mechanisms encompass evasion of cel
We have studied a bottom-gate polycrystalline-silicon thin-film transistor (poly-Si TFT) with amorphous-silicon (a-Si) n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> contacts and center-offset gated structure, where intrinsic poly-Si is used in the center-offset region. The fabrication process is compatible with the conventional a-Si TFT with addition of thermal annealing for crystallization of a-Si. The bottom-gate poly-Si TFT with a 5-m
