In concert with the American Society of Radiologic Technologists, the American College of Radiology and the American Association of Physicists in Medicine, the Society for Pediatric Radiology developed and launched the Image Gently Campaign which is designed to maintain high-quality imaging studies while using the lowest doses and best radiation safety practices available on pediatric patients. Two-dimensional CT images are conventionally rendered so that the view is as though looking up at it from the patient's feet. [105] Several methods that can reduce the exposure to ionizing radiation during a CT scan exist. CT scanning is also employed in the imaging and conservation of museum artifacts. Using CT scans, conservators and researchers are able to determine the material composition of the objects they are exploring, such as the position of ink along the layers of a scroll, without any additional harm. Deciding whether and how to treat incidentalomas is complex, radiation exposure is not negligible, and the money for the scans involves opportunity cost. The radiation dose for a particular examination depends on multiple factors: volume scanned, patient build, number and type of scan sequences, and desired resolution and image quality.

Obstacles and Opportunities in Managing Coexisting Obesity and CKD: Report of a Scientific Workshop Cosponsored by the National Kidney Foundation and The radiation dose reported in the gray or mGy unit is proportional to the amount of energy that the irradiated body part is expected to absorb, and the physical effect (such as DNA double strand breaks) on the cells' chemical bonds by X-ray radiation is proportional to that energy. It can be caused by a tumor pushing on your ureter, kidney stones, or scar tissue. If this is the case, you should know your options for bladder preservation therapy. A specific measure, termed the computed tomography dose index (CTDI), is commonly used as an estimate of the radiation absorbed dose for tissue within the scan region, and is automatically computed by medical CT scanners. After your procedure, youll be taken to the recovery area, called the Post-Anesthesia Care Unit (PACU). Additionally, stents come in differing diameters or gauges, to fit different size ureters. Industrial CT scanning has been utilized in many areas of industry for internal inspection of components. [169] Thus, as is shown in the table above, the actual radiation that is absorbed by a scanned body part is often much larger than the effective dose suggests. KI is peer-reviewed and Youll get fluids through your IV. Your healthcare provider may give you medication to help with bladder symptoms.

This information will explain what a ureteral stent is. However, increased dosage raises the adverse side effects, including the risk of radiation-induced cancer a four-phase abdominal CT gives the same radiation dose as 300 chest X-rays. In the case of non-uniform radiation, or radiation given to only part of the body, which is common for CT examinations, using the local equivalent dose alone would overstate the biological risks to the entire organism.[171][172][173]. Higher resolution is not always suitable, such as detection of small pulmonary masses.
