liver lesion is a common condition, which often detect incidentally. a large proportion of liver masses can be diagnosed by progression in imaging modalities. although, definite diagnosis of liver mass's nature can be made by biopsy of lesion and histopathologic examination, but with imaging findings, we can approach to the diagnosis. in this study, we review many valuable articles and scientif...

Background: Shear wave elastography (SWE) estimates the stiffness of a mass based on the velocity of shear wave propagation by sound waves. Due to higher cell density and angiogenesis, malignant masses have higher stiffness than benign ones. Methods: The present study was a prospective study and was performed on patients who were referred to Ahvaz Golestan Hospital with breast mass during Marc...

echocardiography plays a fundamental role in the evaluation of patients with an intracardiac mass. the ability to distinguish tissue characteristics, location, attachment, shape, size, and mobility non-invasively, quickly, and without the use of ionizing radiation makes echocardiography the ideal diagnostic modality. with careful attention to mass location and morphology, and appropriate applic...

purpose: to report five cases of benign reactive lymphoid hyperplasia of the caruncle and plica and describe their clinical course and pathology. case report: five patients with fish flesh pinkish masses in the caruncle and plica were referred to labbafinejad hospital from 1997 to 2006. the masses were excised. clinical appearance and course as well as pathology and immunohistochemistry confirm...

discussion: the histopathological examination showed increased number of acini with preserved duct-acinar connection, consistent with nodular hyperplasia. the patient had used oral contraceptive pill for four years. introduction: tumors which originate from the bartholin’s glands (bgs) are very rare. many solid masses that arise from the bgs are carcinoma, though these benign solid lesions are ...

Three dogs (Boxer, Labrador Retriever and German Shepherd) between the age of 7-10 years were presented with the history of tumour masses on right caudo-lateral thigh, right cranial forearm and left cranial and caudal thoracic mammary gland region, respectively. Fine needle aspiration cytology of the tumour masses and the sentinel regional lymph nodes were done. Plain radiography was done to ru...

Physical examination and mammography are currently the only proven and reliable methods of early detection of breast cancer. Although, both procedures are highly sensitive, their limited specificity often requires surgical biopsy in order to differentiate between malignant and benign lesions.Palpable mass abnormalities of breast are often difficult to evaluate mammographically, especially in pa...

Introduction: In this paper, a method is presented to classify the breast cancer masses according to new geometric features. Methods: After obtaining digital breast mammogram images from the digital database for screening mammography (DDSM), image preprocessing was performed. Then, by using image processing methods, an algorithm was developed for automatic extracting of masses from other norma...

Background: Risk of malignancy index (RMI) is the best method for discriminating benign and malignant pelvic masses. The aim of this study was to determine the RMI for preoperative evaluation of pelvic mass. Methods: This study was performed on 182 women with adenexal mass referred to Yahyahnejiad Hospital of Babol University of Medical Sciences in Iran from 2007 to 2009.The sensitivity, specif...
