the classification and imaging appearances of vascular masses of the head and neck are reviewed. the radiological appearances of congenital vascular masses (infantile haemangiomas and other congenital vascular tumours, high-flow and low-flow vascular malformations), acquired vascular masses (benign and malignant tumours, non-neoplastic lesions) and other hypervascular masses are described and i...

Adnexal masses are spectrum of diseases from benign non neoplastic and neoplastic masses to malignant neoplasms. Endovaginal ultrasonography (US) is the fisrt and invaluable modality for assessment of adnexal masses because it is available and has a high negative predictive value. Important morphologic features are solid (vascularized) tissue, vascular and thick septations, and papillary projec...

Frost is one of the atmospheric phenomena which seriously threaten crop production. It also causes numerousaccidents in mountainous roads. In this research the Spatial Synoptic Classification SSC method was employed toclassify the type of air masses. For the classification, such meteorological data as: temperature, dew point, mean sealevel pressure, cloudiness, direction and speed of wind were ...

Background: Neck mass is one of the most common clinical findings in all age groups. Differential diagnosis of masses includes a range of pathologies from congenital to infectious or neoplasm. Understanding the risk factors of neck masses can help us to assess them properly. The purpose of this study is to obtain the epidemiological and clinical features of different neck masses in Kerman, Iran...

Framework-based Object-Oriented applications are not as eecient as they could be. This results from the high-genericity of frameworks. However, once the framework is instantiated, part of this genericity can be removed. This is for instance the case when gener-icity is obtained through the use of reeection. This paper takes the Java Serialization framework as a typical example and shows how par...

A seven year-old boy with several painless masses on the ribs and shoulder was referred to our hospital. The masses were so prominent that they prevented the child’s sleep. Since the patient had been ridiculed by his friends due to the rib prominences, he had refused to attend school. After clinical and radiological evaluations, the masses were diagnosed as hereditary multiple exostoses of the ...

 ABSTRACT Background: Evaluation of breast masses in women under 40 years old starts with a Triple Test Score (TTS) which is composed of clinical breast examination, mammography and fine needle aspiration. Increased breast density in this age group decreases the sensitivity of mammography. So deciding whether to biopsy such nondiagnostic lesions or not is subject to challenge. Breast masses up ...
