The American Society of Radiologic Technologists (ASRT) is a professional membership association that serves medical imaging technologists, radiation therapists, and radiologic science students. [1] The organization, located in Albuquerque, New Mexico provides its members with ongoing education and professional development opportunities.
International Society of Radiographers and Radiological Technologists (ISRRT) is a non-governmental organization [1] formed in 1959 [2] which aims to give direction to the Radiological profession as a whole through collaboration with national representative bodies.
A radiologist interpreting magnetic resonance imaging Dr. Macintyre's X-Ray Film (1896). Radiology (/ ˌ r eɪ d ɪ ˈ ɒ l ə dʒ i / rey-dee-ol-uh-jee) is the medical specialty that uses medical imaging to diagnose diseases and guide treatment within the bodies of humans and other animals.
A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
Guidelines for treating resistant hypertension have been published in the UK [45] and US. [46] It has been proposed that a proportion of resistant hypertension may be the result of chronic high activity of the autonomic nervous system, known as "neurogenic hypertension". [47] Low adherence to treatment is an important cause of resistant ...
National Radiologic Technology Week® (NRTW®) is an annual event established by the American Society of Radiologic Technologists to celebrate the important role medical imaging and radiation therapy professionals play in patient care and health care safety. The weeklong celebration highlights the radiologic technology profession and raises ...
Increased neural activity causes an increased demand for oxygen, and the vascular system actually overcompensates for this, increasing the amount of oxygenated hemoglobin relative to deoxygenated hemoglobin. Because deoxygenated hemoglobin attenuates the MR signal, the vascular response leads to a signal increase that is related to the neural ...
Taking an X-ray image with early Crookes tube apparatus, late 1800s.. For the first three decades of medical imaging's existence (1897 to the 1930s), there was no standardized differentiation between the roles that we now differentiate as radiologic technologist (a technician in an allied health profession who obtains the images) versus radiologist (a physician who interprets them).
