PREFACE This book is intended as an assistant textbook in radiation physics and its applications in diagnostic radiological techniques in applied academic medical graduate programs. The book may also be of interest for the large number of professional physicists, who in their daily occupations deal with medical physics and have a need to improve th...

Abstract. Sleep apnea disorder is one of the most widespread respiratory syndromes, interrupting breathing by preventing air from entering the lungs. This paper documents the design and implementation of a cost-effective and easy-to-conduct screening method for detecting and predicting sleep apnea events using a small number of sensors and a small,...

Sleep apnea (SA) is a common respiratory disorder, especially among obese people. It is caused by either the relaxation of the upper respiratory tract muscles or the failure of the neural signal to reach the muscles responsible for breathing, both of which interrupt the patient’s sleep–wake cycles. The traditional method for diagnosing this disorde...

The purpose of this study was to review the uses of MR imaging in assessing IHD, including determine role of MR imaging in detection various aspect of myocardial infarction after late gadolinium enhancement, to evaluation of extent and size of fibrosis or scar after enhancement of late gadolinium and to assessment of myocardial viability prior to r...

Aim of the Study: comparing accuracy, sensitivity and specificity of the magnetic resonance imaging and ultrasound in differentiating and characterizing of uterine masses. Patients and Method: A prospectively studied has been conducted on 41 female patients with suspected uterine masses. They were subjected to ultrasound and magnetic resonance imag...

Introduction: uterine masses represent a very common problem amongst the females. Uterine leiomyoma, adenomyosis, carcinoma of the cervix and the uterus and the endometrial pathology, which include the carcinoma and polyp are the most common of them. The Ultrasound (USG) and Magnetic Resonance Imaging (MRI) appear as significant modalities for the...

Objective : To identify the efficiency of perfusion, weighted magnetic resonance imaging techniques andprotocols in, evaluation of cerebral blood, flow, blood volume, & vascular, permeability of a tumor in thebrain in correlation with viability of brain neoplastic tissues.Material and Methods : One hundred and fifteen patients with histologically p...

Introduction: The masses or cysts of the ovary, masses of the fallopian tube, pathology of the broadligament, and cysts of the para tubal are all referred to as adnexal masses. The first-line imaging modalityis ultrasound. MR imaging has played and continues to be of high importance in treating adnexal diseasepatients.Purpose: To equate the diagnos...

Background: Bladder cancer is the second most common type of cancer of the urinary system in the world, after prostate cancer. Thus, we use a combination of the best imaging technology in the diagnosis and treatment of bladder cancer, because of its accuracy in local staging and grading. Aim of the Study: To determine the accuracy and effectivity o...

ABSTRACT Introduction: The uterine masses constitute one of the most common problems among women. The most common of them are adenomyosis, uterine leiomyoma, carcinoma of uterus and cervix and endometrial pathologies including polyp and carcinoma. Magnetic Resonance Imaging (MRI) and Ultrasound (U/S) appear to be important modalities in diagnosing...

Objectives: To assess the role of Computed Tomography (CT) in identify the chemical composition of urinary stone according to Hounsfield Units (HU) value and to assess the accuracy of CT in determination the chemical composition of urinary stone in comparison with chemical stone analysis and urine examination. Background: Renal stone is one of the...

Background: Brain tumors are the most aggressive disease, and cancerous brain tumors are a severe life-threatening condition. The tumor growth-induced curvature of the brain (mass impact) can cause serious impairment or death as it develops in the cranium, displaces or replaces the surrounding tissue. Tumors are believed to weaken the blood-brain b...

Background: Magnetic resonance cholangiopancreaticography is employed for visualization of biliary tree. The aim of this work is to determine the accuracy and the sensitivity of magnetic resonance choleangiopancreatography technique in diagnosis of the obstructive jaundice and to compare its efficiency with ultrasonographic findings. Patients and M...

Single-tube copper coil (STCC) in near-field wireless power transfer (WPT) is presented in this study to operate low-power devices (LPDs) without depending on a connection to a power source or battery. The transfer distance was increased to 40 cm that facilitates the employment of the STCC system in a good area.. The performance of the proposed sys...

Wireless power transfer (WPT) in medical implanted devices (MIDs) has received significant interest from both academic and the medical industry. These systems have suffered from battery-life that must be charged or replaced. Also, some implant devices are large, leading them to be uncomfortable. In addition, the device may interact with internal ti...

Sleep disorders are common health issues that can affect the multiple aspects of life. Sleep apnea (SA) is the most common sleep disorder, and it is described as a reduction or cessation of airflow to the lungs during sleep. This disorder is usually diagnosed and tested using polysomnography (PSG) in a special laboratory. However, this method is co...

Background: The intracerebral hemorrhage (ICH) can be classified as traumatic and spontaneous. The frontal and temporal lobes are classic sites for traumatic ICH, which are less commonly affected by spontaneous episodes. Computed tomography (CT) scanning is the most accurate radiological method for demonstrating the acute lesion of intracerebral he...

Background: Quantification of proteinuria and urine creatinine concentration are important in kidney failure and chronic kidney diseases (C K D) assessment. In most kidney diseases, urine contains large amounts of protein and there are good correlations between the urine protein to creatinine ratios and the 24 hour urine. Some patients with renal f...

Summary: The magnesium chloride solution used as alternative to the gadollinium contrast medium used in magnetic resonance imaging (MRI), which is used to obtain MRI images for members that need more accurate diagnosis in certain diseases, especially tumors, has been studied. However, Patients may be allergic to this gadollinium or it may cause bl...

PCOS is the most public reason of anovulation, sterility and hyperandrogenism in women, disturbing between five and ten percentage of women of generative age worldwide. Therefore the study focused on these cases and aimed to Ultrasonographic finding in women with polycystic ovary syndrome in correlation with their FSH gene polymorphism. "In current...
