About this study

The goal of this observational study is to learn if using a dedicated urine collection device after CT scans can help reduce the amount of iodinated contrast agent released into hospital wastewater in adult outpatients undergoing contrast-enhanced CT scans. The main questions it aims to answer are: * Does the dedicated urine collection device improve patient acceptance and compliance with post-contrast urine collection? * How much iodinated contrast agent can be recovered from urine collected after CT scans? Participants will: * Have their planned CT scan with iodinated contrast agent as part of their regular medical care. * Wait in the radiology department for about 60 minutes after the contrast injection. * Use a dedicated urine collection device before leaving the hospital. * Answer short questions about their experience with the device. This does not change the CT scan, the contrast agent used, or the standard clinical imaging procedure. The only additional procedure is the use of the dedicated urine collection device after the scan.
