In this paper, a complete system for automatic lung nodule detection from Chest CT data is proposed. The proposed system includes the methods of lung segmentation and nodule detection from CT data. The algorithm for lung segmentation consists of surrounding air voxel removal, body fat/tissue identification, trachea detection, and pulmonary vessels segmentation. The nodule detection algorithm co...

Leading thyroidologists in the United States and in Europe have most frequently recommended radioiodine (RAI) therapy when elimination of a solitary toxic nodule is indicated (1, 2). Interdisciplinary guidelines in Germany, authorized by the national associations of nuclear medicine, endocrinology and surgery, also give RAI administration as the therapy of choice for this indication (3). How th...

To the Editor—We congratulate Cheung et al1 for providing local data on the accuracy of fine-needle aspiration cytology (FNAC) of non-toxic thyroid nodules. In 2003, we retrospectively analysed the results of 192 FNAC of thyroid nodules performed in Queen Elizabeth Hospital between January and June 2001. Forty-three of those patients underwent thyroidectomy and a comparison of the histopatholog...

The increasing number of multidrug-resistant microbes now emerging necessitates the identification of novel antimicrobial agents. Plants produce a great variety of antimicrobial peptides including hundreds of small, nodule-specific cysteine-rich NCR peptides that, in the legume Medicago truncatula, govern the differentiation of endosymbiotic nitrogen fixing bacteria and, in vitro, can display p...

We compared nodule initiation in lateral roots of Pisum sativum (L.) cv Sparkle and in a low-nodulating mutant E2 (sym 5). In Sparkle, about 25% of the infections terminated in the epidermis, a similar number stopped in the cortex, and 50% resulted in the formation of a nodule meristem or an emerged nodule. The mutant E2 (sym 5) was infected as often as was the parent, and it formed a normal in...

A 49-year-old female presented with an aggressive pelvic angiomyxoma (AAM). The completely resected specimen revealed the usual myxedematous tumor with a nodule inside it. Histopathologically, the myxedematous area consisted of bland spindle-shaped cells in the background of blood vessels of varying calibers, and the nodule was composed of tumor cells with epithelioid features. In the nodule, c...

PVA roller brushes are widely used for cleaning after the CMP process, one of semiconductor manufacturing processes. The brush features protrusions called nodules and rotates on wafer in cleaning. This article introduces a model that uses to remove nanoscale impurities. evanescent fields prism enable us observe contact behavior clarify there is little volume near surface during sliding. We clas...

BACKGROUND In our daily experience, the differentiation between a cold and hot nodule is a very important factor for further clinical management of the patient. In this study, we compared the characteristics of incidentally found thyroid nodules detected on computed tomography (CT) to thyroid scintigraphy (TS). METHODS Diagnostic reports from chest CT with intravenous contrast and TS examinat...

OBJECTIVES To review the Early Lung Cancer Action Project experience and the medical literature from 1993 to 2003 on detection of the small, noncalcified pulmonary nodule by CT in order to formulate a management algorithm for these nodules. DESIGN Prospective noncomparative study of smokers without prior malignancy and a review of the medical literature of CT screening of lung cancer. INTER...

OBJECTIVE The controversy that iodized salt may increase the risk of thyroid disorders has been aroused in China during the past decade. Most of studies focused on adult rather than children. We aimed to explore whether iodized salt was associated with an increased risk of thyroid nodule in Chinese children. METHODS The cross-sectional study was conducted in Hangzhou, China, in 2010. Iodized ...
