研究室紹介
Professor On-Gu Cho's research lab specializes in diagnostic and interventional radiology, with a focus on advanced medical imaging techniques for the detection, characterization, and treatment of various neoplastic and benign conditions. The lab investigates the radiological features of rare and complex tumors, such as synovial sarcoma, Brenner tumors, and plexiform neurofibromas, emphasizing the role of CT and MRI in improving diagnostic accuracy. It also explores interventional techniques like radiofrequency ablation, with an emphasis on optimizing procedural outcomes through technical innovation and imaging guidance. The lab contributes significantly to understanding imaging biomarkers and post-interventional complications, such as heterotopic ossification after surgery.

15Radio-frequency thermal ablation is one of the most promising minimally invasive techniques for the treatment of nonresectable hepatic tumors. Essential technical tips to successful radio-frequency ablation therapy were collected from five international experts. They were organized into five categories: understanding the mechanisms and principles of radio-frequency ablation, modulation of tissue physiologic characteristics to increase tumor destruction, strategies of overlapping ablations, strat
Extensive amorphous calcification in a solid mass or solid component in a multilocular cystic mass is a characteristic finding of Brenner tumor of the ovary on CT and MRI.
Our results showed that differences exist in the sonographic features of screening-detected and symptomatic DCIS. Recognition of the many and varied sonographic appearances of DCIS might be helpful to decrease the false-negative rate of bilateral whole-breast sonography and to detect symptomatic mammographically occult DCIS when we use sonography to supplement mammography.
OBJECTIVE: To analyze the incidence of heterotopic ossification (HO) development in incision scars after abdominal surgery and to search for factors relating with its development. METHODS: We retrospectively analyzed the postoperative computed tomographic scans of 152 consecutive patients who underwent abdominal incisions, recording the presence of ossification and its characteristics, the type of surgery and incision, and characteristics of the xiphoid process. The change in size upon follow-up
A case of a 36-yr-old woman with retroperitoneal synovial sarcoma is described. Her presenting symptom was epigastric pain that radiating to the back. On radiologic study, bulky retropancreatic soft tissue mass was detected which showed cystic and solid components. At operation, complete resection of the tumor was not possible because of the adhesion to the vena cava and the liver. During the follow-up, extensive tumor recurrence and liver metastasis were revealed. Primary retroperitoneal synovi
In a 36-year-old man with neurofibromatosis type 1, rare colonic involvement of plexiform neurofibroma is presented. The diagnosis was confirmed by operation. Radiologic findings consisted of marked concentric thickening of the colonic wall with variable attenuation, namely, a "multilayer appearance," as well as clusters of multiple soft tissue nodules in the mesentery.
Purpose: To evaluate post-ablation syndrome after radiofrequency thermal ablation of malignant hepatic tumors. Materials and Methods: Forty-two patients with primary (n=29) or secondary (n=13) hepatic tumors under-went radiofrequency thermal ablation. A total of 65 nodules ranging in size from 1.1 to 5.0 (mean, 3.1) cm were treated percutaneously using a 50W RF generator with 15G expandable needle electrodes. We retrospec-tively evaluated the spectrum of post-ablation syndrome including pain, fe
