Ji Hye Min 교수의 연구실은 주로 간질환, 특히 간세포생식암(HCC)과 담도세포암(IMCC)의 영상진단 및 예후 예측을 중심으로 한 고해상도 MRI 기반 연구를 수행하고 있습니다. 특히 간암의 정확한 진단을 위해 가오산염 강화 MRI(HBA-MRI)와 혈관강화 MRI(ECA-MRI)의 비교 분석, 미세혈관 침윤(MVI)의 영상적 평가 및 예후 연관성 등 정밀 영상의 임상적 응용을 중점으로 연구하고 있습니다. 또한, 영상 유체역학 및 조직학적 변화와의 연관성 분석을 통해 영상 소견이 치료 전략 수립에 어떻게 기여할 수 있는지에 대한 기초를 마련하고 있습니다.

We intraindividually compared the efficacy of magnetic resonance imaging (MRI) with extracellular contrast agents (ECA-MRI) and MRI with hepatobiliary agents (HBA-MRI) for the diagnosis of hepatocellular carcinoma (HCC) using the Liver Imaging Reporting and Data System (LI-RADS). Between November 2016 and November 2017, we enrolled 91 patients with chronic liver disease who underwent both ECA-MRI and HBA-MRI within a 1-month interval for a first detected hepatic nodule on ultrasound. In total, 1
Background Accurate identification of microvascular invasion (MVI) in hepatocellular carcinoma (HCC) before treatment is critical for selecting a proper treatment strategy. Purpose To evaluate the interobserver agreement and the diagnostic performance of the MRI assessment of MVI in HCC according to the level of radiologist experience. Materials and Methods This retrospective study included 100 patients with surgically confirmed HCCs smaller than 5 cm who underwent gadoxetic acid-enhanced MRI be
Purpose To identify whether arterial enhancement pattern at MRI could predict the prognosis after surgical resection of intrahepatic mass-forming cholangiocarcinoma (IMCC). Materials and Methods Patients who underwent curative hepatic resection and preoperative MRI for IMCC from November 2007 to September 2016 were retrospectively evaluated. MRI enhancement pattern was classified by two radiologists. Recurrence and death data were retrieved until September 31, 2017. Prognostic factor analysis wa
Fusion imaging with CEUS and CT/MR imaging is highly effective for percutaneous RFA of very-early-stage HCCs inconspicuous on fusion imaging with B-mode US and CT/MR imaging.
More severe and extensive atrophy in the lumbar MF muscle was associated with radiculopathy. Thus, we might consider the presence of radiculopathy when severe and extensive multi-level involvement of MF atrophy is seen in MRI.
Renal BOLD MRI at 3 T is a feasible technique and may be useful for differentiating various renal lesions.
RFA combined with TACE under dual guidance of biplane fluoroscopy and US is technically feasible and effective for intermediate-sized HCC treatment.
There is no consensus regarding the ideal imaging modality or follow-up interval after resection of HCC. Non-contrast MRI had comparable performance to that of gadoxetic acid-enhanced MRI in the detection of HCC recurrence during surveillance ≥1 year after surgery.
