Magnetic resonance imaging

easiest, inexpensive, and universally available in any hospital emergency center. It still consider as the first diagnostic modality at many facilities, especially those that are not trauma centers. Plain radiograph put out the foundation of day-to-day imaging. They may on their own be enough to provide a diagnosis, or they may need to be completed by other modalities, such as computed tomography (CT). [10][13] Plain radiograph are of limited value in isolated orbital wall injuries, but the…

By Jonas Wilson, Ing. Med. CT KUB A computerized tomography (CT) scan of the kidneys, ureters and bladder (KUB) is referred to as a CT KUB. The scan is done to obtain images from different angles of the urinary system and surrounding structures, which encompasses an area from the superior poles of the kidneys, descending down to the pubic symphysis. These images are acquired in cross-sections or slices, hence the terminology tomographic. They are then processed through a computer to produce…

CHAPTER ONE 1.0 INTRODUCTION 1.1 Background of the Study Ultrasonography is an excellent modality for examining abdominal structures including the location and dimensions of canine kidneys (Remichi et al., 2014). It involves a non-invasive procedure for examination of kidney diseases (Sampaio and Araujo, 2002) and offers advantages over radiography as there are no side effects of radiation and contrast agents (Nyland et al., 1995). Canine kidneys are located in the retroperitoneal region of the…

Interventional radiology is considered a specialized modality of radiology that deals mostly with invasive image-guided procedures. With advances in technology, interventional procedures can be performed on several areas of the body with success in conjunction with using live x-rays during exams. Cerebral aneurysms often can be in susceptible areas of the brain, and usually, are considered somewhat high risk in nature. The use of endovascular coiling can prove to not only be successful, but…

Alternative Imaging for MRI in MS MRI is a great tool for medical imaging and widely used for Multiple Sclerosis (MS), but it has some limitations in lacking specificity1. New emerging techniques such as transcranial magnetic stimulation (TMS) and optical coherence tomography (OCT) have the potential to address issues not resolved by current MRI techniques. TMS is a non-invasive technique used for monitoring the central nervous system (CNS) activity and response in a pain-tolerated manner. It…

One beautiful, sunny day in late fall when the leaves were changing colors and there was a little chill in the air, my sister and I were in her jeep with our mom scouring the area for sales. Tonya, my sister, treated us to Hardees biscuits to eat while on our search. We were all excited about different items we purchased from the various sales. The day was feeling like another normal day to look for yard sales with my family. As I stared out the window, thoughts of the peaceful day flooded my…

It was recorded that 12 out of 35 patients, suffered from extrahepatic tumour. This was revealed by PET/CT combined and by CT scan single-handedly. The extrahepatic tumours in two of the patients were not detected by PET and PET/CT; those were recorded to have node of 2 –cm lymph in the hepatoduodenal ligament. It is furthermore, true that both forms of the scans (CT and PET/CT) reported extrahepatic tumour in patients that did not have it at all. The CT scan reported it in 3 out of 23 patients,…

Introduction: Gastro Intestinal Tract (GIT) is an important site for wide variety of lesions which include congenital, inflammatory, neoplastic conditions. The invention of flexible fiber-optic endoscope is a very good achievement towards the diagnostic field. With the use of this facility direct vision of diseased mucosa and biopsy of mucosal lesions, therapeutic induction and photographic visualization of the lesions are made possible. Aim of the study: Aim of this study is to know the…

Computed tomography (CT) is a computerized method that uses a computer to process the data collected from the passage of x-ray beams through the region of interest. The multislice CT (MSCT) means CT that the system equipped with multiple rows of CT detectors to create images of multiple sections. The data obtained from the patient will be transformed into “cuts” or cross-sectional slices of the human body (Romans, 2011). In early 1970, they use a single slice CT scan that contributes too many…

element in the identification, diagnosing, and treatment of many types of medical conditions” (http://www.healthline.com/health/x-ray#Overview1 ). Over the next century, Roentgen and others who followed his work would introduce new modalities of imaging and also drastically improve the efficiency and safety of these modalities as well. One modality that has significantly improved upon the two-dimensional x-ray is known as Computed Tomography. This modality gets its name from the idea of…
