Older adults with chronic conditions are at higher risk for complications from contrast media due to several physiological and pathological factors. As individuals age, the kidneys often show a decline in function, which can impair the clearance of contrast agents from the body. Additionally, chronic conditions such as diabetes, hypertension, and cardiovascular disease frequently accompany aging and can exacerbate the risk of contrast-induced nephropathy and other complications.

Moreover, older adults often have altered pharmacokinetics and increased susceptibility to adverse reactions due to polypharmacy, which can further complicate their medical management during imaging procedures.

While children under 12, patients with previous imaging procedures, and healthy adults may have their own considerations regarding contrast use, they typically do not carry the same level of risk related to the cumulative impact of aging and chronic health conditions that can significantly affect how their bodies respond to contrast media. Therefore, it's essential to assess patients' overall health and specific risk factors, particularly in older adults with chronic conditions, when considering the use of contrast media in imaging.
