研究室紹介
Professor Ji Soo Choi's research lab specializes in diagnostic radiology and medical imaging, with a focus on advancing the accuracy and efficiency of medical image interpretation through innovative imaging techniques and artificial intelligence. The lab investigates the application of high-resolution ultrasound, CT, MRI, and diffusion-weighted imaging in the diagnosis and prognosis of cancers, particularly thyroid and breast cancer. A key research direction involves integrating deep learning and spectroscopic techniques—such as high-resolution magic angle spinning MRS—with histopathological findings to improve personalized cancer management.

15OBJECTIVE: The purpose of this study was to compare the diagnostic accuracy of ultrasound imaging with that of CT in the preoperative evaluation of primary tumors and cervical lymph nodes in patients with papillary thyroid carcinoma and to determine whether CT has greater diagnostic value than ultrasound alone in the care of these patients. MATERIALS AND METHODS: The study population consisted of 299 consecutively registered patients with pathologically proven papillary thyroid carcinoma. The di
Deep learning-based CAD could improve radiologists' diagnostic performance by increasing their specificity, accuracy, and PPV in differentiating between malignant and benign masses on breast US.
Colonic pseudoobstruction can be diagnosed on the basis of CT findings that show extensive colonic dilatation without an obstructive lesion at the intermediate transitional zone or adjacent to the splenic flexure. Pathologic examination reveals that intramural ganglion damage has a high tendency to occur in cases of chronic colonic pseudoobstruction.
Both breathhold and non-breathhold DWI are comparable for the detection or characterization of focal liver lesions at 3.0T; however, non-breathhold DWI provides higher SNR and CNR than breathhold DWI. In addition, although free-breathing and navigator-triggered DWI sequences show similar performance for 3.0T liver imaging, free-breathing DWI is more time efficient than navigator-triggered DWI.
The purpose of this study was to examine the correlation between high-resolution magic angle spinning (HR-MAS) magnetic resonance (MR) spectroscopy using core needle biopsy (CNB) specimens and histologic prognostic factors currently used in breast cancer patients. After institutional review board approval and informed consent were obtained for this study, CNB specimens were collected from 36 malignant lesions in 34 patients. Concentrations and metabolic ratios of various choline metabolites were
To retrospectively investigate whether background parenchymal enhancement (BPE) of the contralateral breast on preoperative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is associated with therapeutic outcomes following neoadjuvant chemotherapy (NAC) in unilateral invasive breast cancer. The institutional review board approved this study, and informed consent was waived. Between 2009 and 2011, 93 women with unilateral invasive breast cancer (43 premenopausal women who performed
The purpose of this study was to determine whether metabolic profiling of core needle biopsy (CNB) samples using high-resolution magic angle spinning (HR-MAS) magnetic resonance spectroscopy (MRS) could be used for predicting pathologic response to neoadjuvant chemotherapy (NAC) in patients with locally advanced breast cancer. After institutional review board approval and informed consent were obtained, CNB tissue samples were collected from 37 malignant lesions in 37 patients before NAC treatme
