Epilepsy is known as a neurological disorder caused by disturbance in electrical brain signals. Almost one percent population in the world experience epileptic seizures from which 30% people need medical surgery and others are cured by antiepileptic drugs. Epilepsy is divided into generalized and partial epilepsy. Diagnosis of epilepsy is a major problem; several Image processing and signal processing techniques h Read More

Various modalities are available for the diagnosis of diseases affecting the oral and maxillofacial regions and the accuracy of diagnosis for many kinds of diseases in oral and maxillofacial regions is readily increasing. In particular, considerable research has focused on the use of magnetic resonance (MR) images for functional evaluation, as well as morphological examination, due to the high spatial resolution of the images, Read More

In this paper, we propose a method to extract sternocleidomastoid and longus capitis/colli automatically and measure the thickness of those muscles from cervical vertebrae ultrasound images. Extracting sternocleidomastoid is relatively easy but for longus capitis/colli case, due to the brightness sensitivity, it requires much more computationally burdensome procedures. In the binarization process, instead of simple and Read More

Coronary CT angiography has revolutionized the management approaches in patients with atypical chest pain and nonspecific symptoms that may not be related to the cardiac disease. Presence of extracardiac findings on coronary CT angiography is very common, and some of these findings have clinical significance which requires additional workup to improve patient outcome. The aim of this study is to prospectively assess t Read More

Purpose: To determine the variations and abnormalities of major thoracic vascular structures in patients exposed to thoracic examination via computerized tomography with 64 detectors. Materials and Methods: In this retrospective study, 2,479 patients who underwent thoracic computed tomography between May 2006 and October 2007 in the Radiation Department at Dicle University’s School of Medicine were examined. Read More

Objectives: Pulmonary thromboembolism (PTE) is an emergent disease with high mortality. Wells and revised Geneva scores are commonly used probability scales in PTE diagnosis. Computed tomography pulmonary angiography (CTPA) is the radiological diagnostic method. We aimed to determine computed tomography pulmonary arterial obstruction index ratio (CTPAOIR) which indicates degree and the extent of the thr Read More

In daily medical practices intravenous (IV) catheterization is performed on the majority of patients to inject medication or to get blood samples. Patients whose veins are not visible require multiple attempts in order to insert the catheter accurately. Different techniques have been proposed and a few are in use at present to localize the veins in order to avoid the wrong catheterization and reduce the number of attempts. In li Read More

Background: There are conflicting results in estimation of primary renal tumors by F-18 FDG PET/CT in the literature. Aim of this study is to evaluate diagnostic efficiency of F-18 FDG PET/CT and dual time imaging in the diagnosis of renal cell cancer. Methods: Dual time F-18 FDG PET/CT examinations of 17 patients (55.2 ± 9.9 years old; 7 F, 10 M) with prediagnosis of renal cell cancer were retrospectively evaluated. All of Read More

The contrast agents have been developed to enhance and improve the quality of images in radiology practice in order to define the physiology and pathophysiology in various tissues, to detect and define neoplastic, inflammatory and functional abnormalities. Most contrast agents for magnetic resonance imaging approved for human applications are gadolinium-based. Paramagnetic chelates containing lanthanide ion, gadoliniu Read More

Myositis ossificans is an uncommon disease with abnormal formation of bone in inflammatory muscle. Majority of cases are related to major or minor trauma (ie myositis ossificans traumatica). The development of myositis ossificans traumatica due to overuse is rare. To the best of our knowledge, there were only three such cases reported in the literatures. This is the first reported case of development of myositis ossific Read More
