UNLABELLED BACKGROUND To investigate the 3.0-Tesla (3 T) magnetic resonance imaging (MRI) characteristics of primary adnexal lesions for discriminating benign from malignant lesions. METHODS One hundred thirty-nine patients with pathologically proven primary adnexal masses referred for 3 T MRI assessment preoperatively were included. Baseline characteristics, components, and conventional M...

It is crucial to rule out any cancer in an ovarian mass. Following initial diagnosis, it the most essential issue and has a significant impact on how patient will be managed. Therefore, accurate way distinguish between benign malignant mass would allow for best clinical evaluation could perhaps lessen number of unneeded laparotomies performed lesions disease.

Reproductive abnormalities cause major losses of sheep production. Abattoir materials were used todetermine the extent of reproductive wastage. Reproductive tracts were collected from 524 ewes slaughtered at Urmia slaughter-house in Urmia, northwest of Iran, during a period of 12 months. Overall, 30.10% of the ewes examined were pregnant. A total of 149 (28.44%) tracts developed acquired reprod...

In order to study the prognostic value of quantifying the chromatin structure of cell nuclei from patients with early ovarian cancer, low dimensionality adaptive fractal and Gray Level Cooccurrence Matrix texture feature vectors were extracted from nuclei images of monolayers and histological sections. Each light microscopy nucleus image was divided into a peripheral and a central part, represe...

Background: This experimental study examined the effect of erythropoietin (epoetin alfa) on rat model and particularly in an ovarian ischemia reperfusion (IR) protocol. The effects of that molecule were studied pathologically using mean ovarian congestion (OC) lesions. Materials and methods: 40 rats of mean weight 247.7 g, 16-18 weeks old, were used in the study. OC lesions were evaluated after...

BACKGROUND Endometriosis is a common condition which causes pain and reduced fertility. Treatment can be difficult, especially for severe disease, and an accurate preoperative assessment would greatly help in the managment of these patients. The objective of this study is to assess the accuracy of pre-operative transvaginal ultrasound scanning (TVS) in identifying the specific features of pelvi...

Diffuse lesions of the white matter of the human brain are common pathological findings in magnetic resonance images of elderly subjects. These lesions are typically caused by small vessel diseases (e.g., due to hypertension, diabetes), and related to cognitive decline. Because these lesions are inhomogeneous, unsharp, and faint, but show an intensity pattern that is different from the adjacent...

OBJECTIVE To assess the diagnostic value of aspiration cytology in individual cystic lesions of the ovary. STUDY DESIGN During a 42-month period, 235 cystic ovarian lesions were investigated by fine needle aspiration with cytologic examination (FNA). RESULTS Almost 56% (131/235) of the aspirates were devoid of diagnostic cells. The 104 diagnostic aspirates comprised 49 follicular cysts, 4 e...
