Dexa Scan: Overview, Preparation, Procedure, Recovery, Risks, and Aftercare
Overview
An osteoporosis and fracture risk can be assessed with a Dexa scan, also known as dual-energy X-ray absorptiometry. By using low-dose X-rays to produce detailed images of the bones, it is a painless and non-invasive procedure.
Preparation
It is not necessary for patients to prepare for a Dexa scan in advance. However, any medications, supplements, or medical conditions should be mentioned to the healthcare provider, as they may affect the results. As part of the imaging process, patients may be advised to wear loose, comfortable clothing and to remove metal objects, such as jewelry and belts.
Procedure
A Dexa scan involves lying flat on a table and receiving low-dose X-rays from a scanning arm. In order to determine bone density and strength, the scanner measures the amount of X-ray energy absorbed by the bones. A typical scan usually takes 10 to 30 minutes, depending on the areas being scanned.
Recovery
After a Dexa scan, patients can resume their normal activities immediately. A healthcare provider may provide patients with the results of the scan and discuss any further steps or recommendations based on the results. Following the procedure, there is no recovery time or special precautions needed.
Risks
As with any medical procedure involving radiation, Dexa scans are generally considered safe and pose minimal risks. The amount of radiation exposure from a Dexa scan is extremely low, significantly lower than that of a standard X-ray, making it safe for a wide range of patients, including pregnant women and children. Patients should inform their healthcare provider if they are pregnant or may be pregnant before undergoing a Dexa scan, as radiation exposure is a small risk.
Aftercare
Dexa scans typically do not require any specific aftercare. It is important for patients to follow up with their healthcare provider for further evaluation and guidance if they have any concerns or questions about the scan results.
In conclusion, a Dexa scan is a valuable diagnostic tool used to measure bone density and determine whether a person is at risk for osteoporosis and fractures. Patients can take proactive steps to maintain bone health by undergoing a Dexa scan as recommended by their healthcare provider and discussing the results with their provider.
