What is a low dose CT scan?
Scanning with low dose of computer tomography (CT) provides an image of the interior of the patient's body with minimal radiation. This reduces the risks for the patient by limiting the overall radiation exposure in conjunction with a medical imaging study. A low CT scan compromise is that images may not be sufficient to meet the test needs. Development in CT technology has led to a significant improvement in a low dose device, making higher radiation doses more and more necessary. Slices can be re -assembled in a computer program to create a three -dimensional image that reveals interesting structures, abnormal growth and other functions. One of the problems with CT technology is that it can include a high dose of radiation to capture all the necessary slices, which potentially increases the risk of cancer or other problems later in life.
patients receiving a low CT scan have a much lower amount of RADIIGHT EXPOSION. The device can also use multiple detectors, allowing you to capture several slices at the same time. This reduces the amount of time the patient must spend in the machine and also reduces the overall dose. Technicians can carefully calculate the dosage settings to adjust the patient and create a low CT scan to provide sufficient resolution with the least risk to the patient.
The level of radiation exposure may depend on the scanned device and the scanned body area. CT scanning with a low dose can in some cases use up to 90% less radiation, while in others it is less dramatic. Patients with questions or concerns about radiation exposure may discuss this with a technician and a doctor who ordered a test, if you want to know more about the risks and benefits of CT scanning.
There may be cases where a low dose scanning is not suitable because it does not offer sufficient image clarity. It can depend on why she was a stuDie ordered, specific properties of the patient and type of equipment used. Doctors may discuss the possibilities with patients and review the situation to determine which type of testing would be best. They want to avoid the need to repeat the test for the second set of images.
