Which diagnostic imaging technique is sometimes used to evaluate organ involvement in SLE?

Ultrasound is a useful diagnostic imaging technique for evaluating organ involvement in systemic lupus erythematosus (SLE) because it provides real-time imaging of organs and tissues, allowing for the assessment of fluid accumulation, organ enlargement, and other abnormalities associated with lupus. It is non-invasive and does not involve exposure to ionizing radiation, making it safer for patients who may require multiple evaluations over time due to the chronic nature of SLE.

In the context of SLE, ultrasound can effectively assess conditions such as lupus nephritis by visualizing the kidneys and any potential complications like renal edema or cysts. Additionally, it can be beneficial in evaluating joint involvement, pericardial effusion, and even assessing the liver or spleen for signs of lupus-related changes.

Although other imaging modalities like CT scans and MRIs can also be utilized for assessing organ involvement, ultrasound stands out for its practicality, accessibility, and ability to dynamically observe physiological changes. X-rays are generally limited to evaluating bone and joint changes and do not provide the comprehensive view needed to assess internal organ involvement directly related to SLE.
