OBJECTIVE The objective of this study was to analyze the imaging findings of phlebosclerotic colitis in comparison with histologic findings. CONCLUSION Calcifications and/or obstructions of the veins of the colonic wall and adjacent mesentery and collateral formation, edematous thickening of the colonic wall, and increased density in the fatty tissue of(More)
The purpose of this study was to elucidate the role of the superior thyroid artery in intra-arterial infusion chemotherapy for laryngeal and hypopharyngeal cancers. Thirty-nine patients with laryngeal cancer and 29 patients with hypopharyngeal cancer underwent intra-arterial infusion chemotherapy. We performed a retrospective analysis of the feeding(More)
Oestrogen receptor-alpha (ERα), encoded by the ESR1 gene located on 6q25, is a nuclear transcription factor. Since it was reported in 2007 that more than 20% of breast cancers show ESR1 gene amplification, there has been considerable controversy about its frequency and clinical significance. We set out to assess the frequency and levels of ESR1(More)
Diffusion-weighted imaging (DWI) has been used to characterize not only the brain, but also the breast by implementation of faster imaging techniques and higher magnetic field strengths. However, the optimum b value, which is an important scan parameter for DW images contrast on 3 T breast magnetic resonance imaging (MRI) has not been established. The(More)
We evaluated the oncologic and cosmetic outcome in patients with breast cancer treated with wide excision, transposition of adipose tissue with latissimus dorsi muscle (LDM), and axillary dissection followed by radiotherapy. In this study, a wide excision of breast tissue was performed to obtain tumor-free margins. The subsequent breast deformity was not(More)
In Japan, there are approximately 32 000 deaths ( approximately 30 deaths per 100 000) per year due to hepatocellular carcinoma (HCC), and it is the third most common cancer in men and fifth in women. Approximately 90% of them are associated with chronic liver diseases due to hepatitis C or B virus infection. Therefore, it has become possible to detect(More)
Secondary bile acid-producing bacteria were isolated from human feces to improve our appreciation of the functional diversity and redundancy of the intestinal microbiota. In total, 619 bacterial colonies were isolated using a nutrient-poor agar medium and the level of secondary bile acid formation was examined in each by a liquid culture, followed by(More)
PURPOSE The purpose of this study was to evaluate the magnetic resonance imaging (MRI) features of breast cancer according to intrinsic subtypes and to investigate whether the MRI and immunohistochemical findings were related to neoadjuvant chemotherapy (NAC) effects. MATERIALS AND METHODS The MRI in 116 women with breast cancers who underwent NAC was(More)
True tracheal bronchus (TTB) is a rare anomaly in which a lobar or segmental ectopic bronchus arises from the trachea. We examined the frequency and multidetector computed tomography (MDCT) appearances of TTB. We retrospectively analyzed 9781 chest MDCT examinations. In cases in which there was an abnormal bronchus suggesting TTB on axial CT images, the(More)
