Introduction: To explore diagnostic potential of computerize texture analysis methods in discrimination of the normal, benign and malignant ovarian lesions by CT scan imaging. Materials and Methods: Ovarian CT image database consists of 10 normal, 10 benign and 3 malignant which were reported by radiologist and proven by clinical examinat...
in this study reference as one of the five cohesive devices in the achievement of textuality in english and persian narrative/descripitive written texts is focused on and analysed . to do so , the theoretical framework elaborated by halliday and hasan (1976) and its version adapted by the writer to match the sub-types of reference in farsi are applied to the analysis of reference in english and...
OBJECTIVE To examine ultrasonographic predictors of ovarian development in European eels (Anguilla anguilla) undergoing hormonal treatment for assisted reproduction. ANIMALS 83 female European eels. PROCEDURES Eels received weekly IM injections of salmon pituitary extract (first injection = week 1). Ultrasonography of the ovaries was performed twice during hormonal treatment (weeks 7 and 11). E...
BACKGROUND Nuclear texture analysis gives information about the spatial arrangement of the pixel gray levels in a digitized microscopic nuclear image, providing texture features that may be used as quantitative tools for prognosis of human cancer. The aim of the study was to evaluate the prognostic value of adaptive nuclear texture features in early stage ovarian cancer. METHODS 246 cases of ...
Ovarian cancer mostly presents with extensive peritoneal cavity and extraperitoneal dissemination. Satisfactory complete resection of the lesions is one key factors to improve prognosis. The trend surgical extra-ovarian tissues organs invaded by tumor has become obvious in order remove all primary loci metastases as much possible minimize residual lesions. This article provides a literature rev...
Characterization of benign and malignant focal kidney lesions such as angiomyolipomas (AMLs) and renal cell carcinomas (RCCs) from ultrasound images is an intimidating task for radiologists due to their enormously overlaying sonographic presences. In the present work the main focus is on the aspect of variations in texture patterns shown by focal kidney lesions. In order to visualise these text...
Background and purpose: The purpose of this study was to determine the serum concentration of copper (Çu), zinc (Zn) and copper/zinc ratio (Çu/Zn) in patients with ovarian cancer to compare with those in patients with benign ovarian lesions. Materials and methods: This cross-sectional study was carried out on 50 patients with ovarian cancer (malignant group) and 50 patients with benign ova...
PURPOSE The purpose of this study was to investigate statistical differences with MR perfusion imaging features that reflect the dynamics of Gadolinium-uptake in MS lesions using dynamic texture parameter analysis (DTPA). METHODS We investigated 51 MS lesions (25 enhancing, 26 nonenhancing lesions) of 12 patients. Enhancing lesions (n = 25) were prestratified into enhancing lesions with incre...
