'Lung Cancer Alliance (LCA) called the new screening guidelines announced by the National Comprehensive Cancer Network (NCCN) "a positive step in the right direction that will encourage those at high risk for lung cancer to fully investigate their ...'

'The advent of computed tomography (CT) has revolutionized diagnostic radiology. Since the inception of CT in the 1970s, its use has increased rapidly. It is estimated that more than 62 million CT scans per year are currently obtained in the United ...'

'This article discusses CT radiation dose, the measurement of CT dose, and CT image quality. The most commonly used dose descriptor is CT dose index, which represents the dose to a location (e.g., depth) in a scanned volume from a complete series of ...'

'This procedure is reviewed by a physician with expertise in the area presented and is further reviewed by committees from the American College of Radiology (ACR) and the Radiological Society of North America (RSNA), comprising physicians with expertise ...'

'Radiocontrast agents (also simply contrast agents or contrast materials) are compounds used to improve the visibility of internal bodily structures in an X-ray image. Contrast agents are also used in MRI (Magnetic Resonance Imaging). Although MRI is ...'

'BACKGROUND: CT enterography yields striking findings in the bowel wall in Crohn's disease. These images may help to evaluate whether small bowel narrowing results from active disease requiring anti-inflammatory therapy. However, the clinical relevance ...'

'Molecular imaging was both a highlighted topic and an integral part of many of the scientific presentations and exhibits, educational offerings, and technologic advances on display at the 93rd Scientific Assembly and Annual Meeting of the Radiological ...'

'In spiral computed tomography (CT), dose is always inversely proportional to pitch. However, the relationship between noise and pitch (and hence noise and dose) depends on the scanner type (single vs multi detector row) and reconstruction mode ...'

'X-Ray grids consist of a series of lead strips placed in front of the X-Ray film, and are used in some diagnostic techniques to improve image quality by stopping scatter radiation from reaching the X-Ray film. The grid was invented by Dr Gustave Bucky ...'
