OBJECTIVES To analyze the texture features on cranial sonography in preterm neonates with white matter injury quantitatively and to correlate these features with magnetic resonance imaging (MRI). METHODS The study included 33 preterm neonates treated in our neonatal intensive care unit who underwent serial cranial sonography and brain MRI near term. Patients were subdivided into 3 groups acco...

BACKGROUND We conducted our study on 1110 patients with breast masses in order to investigate different aspects of power Doppler sonography (PDS) for differentiating between benign and malignant breast lesions and their prognostication. MATERIALS AND METHODS This study was conducted on the women who were referred to the sonography units of University Hospitals for breast sonography and had a ...

Introduction: Breast cancer is one of the most common cancers in women. Involvement regional lymph nodes by breast has shown to be a significant marker overall diagnosis patients. In this study, we aimed investigate role gray-scale ultrasound and elastography discriminating benign from malignant axillary patients with cancer. Methods: analytical who were referred sonography ward tertiary medica...

The number of bits assigned to represent the color intensity at image pixels is usually referred as the bit depth. When the bit depth is not sufficient, images suffer from ridge-like structures known as false contours. Bit-depth limitations become important when low-contrast details are required, as in medical imaging, aerial/satellite photography, and high-quality scanning applications. In thi...

The choice and detailed design of structuring elements plays a pivotal role in the morphologic processing of images. A broad class of morphological operations can be expressed as an equivalent supremum of erosions by a minimal set of basis filters. Diverse morphological operations can then be expressed in a single, comparable framework. The set of basis filters are data-like structures, each fi...

Recent advances in the imaging capabilities of gray scale sonography have increased the accuracy with which gallstones may be diagnosed. Since the sonographic diagnosis of gallstones is often followed by surgery without further confirmatory studies, the avoidance of false-positive diagnoses assumes major importance. In an attempt to improve diagnostic accuracy, 420 gallbladder sonograms were ev...
