The author is going to evaluate the role of cross-sectional imaging in the clinical management of infarcted stroke‚ and the role of the radiographer within the patient’s pathway. Non Imaging Tests In the ambulance‚ the patient is screened using diagnostic tests to determine whether a stroke is suspected and to rule out hypoglaecemia (Royal College of Physicians‚ 2008).The hospital would be informed and the

Introduction It is widely accepted that clinical interviewing is the fundamental diagnostic tool in psychiatry. Indeed‚ Schreiber states that “the psychiatric interview is the essential vehicle for assessment of the psychiatric patient.” Unlike other areas of medicine‚ psychiatry lacks external validating criteria‚ such as lab tests or imaging‚ to help confirm or exclude diagnoses. With the clinician’s diagnosis and subsequent treatment plan being determined by the clinical data obtained from the

Evidence from two case studies are presented‚ which use the MRI sequences discussed within this report. Consequently‚ the recent advances in diagnostic techniques and methodologies will be analysed and evaluated.

Sonographers need to develop a professional way about themselves‚ while being empathetic‚ patient‚ understanding and reassuring to patients (Romanosky). This demeanor of professionalism is necessary in instances where someone is facing a tragedy such as cancer‚ a disease that is untreatable or the death of an unborn baby that could potentially be revealed during the ultrasound.

Polycystic kidney disease (PKD) is a genetic disorder characterized by the growth of numerous cysts in the kidneys. The kidneys are two organs‚ each about the size of a fist‚ located in the upper part of a person’s abdomen‚ toward the back. The kidneys filter wastes and extra fluid from the blood to form urine. They also regulate amounts of certain vital substances in the body. When cysts form in the kidneys‚ they are filled with fluid. PKD cysts can profoundly enlarge the kidneys while replacing

Ultrasounds are becoming a common diagnostic procedure in the medical field because they can measure and detect abnormalities. Ultrasound instruments which are also known as sonographic instruments operate by using high frequency sound waves. These sound waves operate using a frequency range of 1 to 18 megahertz that can be used for imaging. These high-frequency sound waves are out of range of human hearing. The lower frequency of the sound waves produce less resolution but can produce images

Ultrasound are two of the main imaging techniques used in radiography. For the purposes of this essay‚ we will look at conventional x-rays and diagnostic ultrasound. Conventional x rays are non-invasive diagnostic techniques that are used to capture images of the body’s organs and bones. Diagnostic ultrasounds are high frequency sound waves to create an image of soft issues in the body such as muscles‚ joints‚ and internal organs. As examined below‚ while both are used in diagnostic radiography‚ they have
