RATIONALE AND OBJECTIVES The aim of this study was to evaluate and compare the diagnostic performance of elastography, B-mode ultrasound (US), and a combination of elastography and B-mode US for the differentiation of small breast masses. MATERIALS AND METHODS A total of 315 breast masses < 1 cm (267 benign, 48 malignant) in 278 patients were examined(More)
OBJECTIVE The purpose of this study was to determine the clinical significance of the incidental finding of hypermetabolic foci in the breast at (18)F-FDG PET/CT in patients with malignant disease other than breast cancer or during a screening examination. MATERIALS AND METHODS The files of 13,897 women who underwent FDG PET/CT from November 2004 to(More)
BACKGROUND The reported mortality rates and prognoses of bullous pemphigoid (BP) vary among different countries. However, the mortality rate of BP has not been investigated in Korea. OBJECTIVE We sought to evaluate the mortality rate of Korean patients with BP in comparison to that of an age-matched general population in Korea, and to identify prognostic(More)
Several cases of serologically diagnosed hepatitis E have been reported in South Korea; however, there have been no documented cases of zoonotic transmission with virologic characterization of hepatitis E virus (HEV). We report on a sporadic case of autochthonous acute hepatitis E after ingestion of raw bile juice obtained from a wild boar living on a(More)
A series of bromophenols was obtained by isolation from red alga Odonthalia corymbifera and by reactions of bis(hydroxyphenyl)methanes with bromine. New bromophenols including 3,3',5,5'-tetrabromo-2,2',4,4'-tetrahydroxydiphenylmethane (10), a regioisomer of the potent antimicrobial natural product, together with known derivatives were synthesized in high(More)
OBJECTIVE To compare the detection performance of the automated whole breast ultrasound (AWUS) with that of the hand-held breast ultrasound (HHUS) and to evaluate the interobserver variability in the interpretation of the AWUS. MATERIALS AND METHODS AWUS was performed in 38 breast cancer patients. A total of 66 lesions were included: 38 breast cancers, 12(More)
BACKGROUND FDG PET/CT and DWI are both functional modalities that indirectly represent the biological characteristics of cancer, but there are few studies exploring the association between the two modalities and prognostic factors. Our study attempted to evaluate the mutual association by comparing the prognostic factors, SUV(max) value of PET/CT, and ADC(More)
The purpose of this study was to compare the diagnostic performance of elastography, conventional ultrasonography (US) and combined conventional US and elastography for differentiation of papillary breast lesions. A total of 95 papillary lesions (69 benign, 20 atypical and 6 malignant) in 87 patients were examined with conventional US and elastography. We(More)
OBJECTIVES The purpose of this study was to evaluate the diagnostic utility of sonographic elastography in differentiating reactive and metastatic axillary lymph nodes in breast cancer. METHODS A total of 64 lymph nodes (reactive, n = 33; metastatic, n = 31) from 62 patients with breast cancer were examined by both B-mode sonography and elastography from(More)
Magnaporthe grisea is a fungal pathogen of rice that forms appressoria that penetrate the outer cuticle of the rice plant. Data from recent studies indicate that M. grisea isocitrate lyase (ICL), a key enzyme in the glyoxylate cycle, is highly expressed during appressorium-mediated plant infection. Bromophenols isolated from the red alga Odonthalia(More)
