can you drink water before a ct scan

You can generally drink water before a CT scan, even if fasting is required for solid foods. Drinking water is often allowed and sometimes encouraged, especially if the scan involves the abdomen, pelvis, or urinary system, to help get clearer images and keep you hydrated. However, caffeinated drinks should usually be avoided before scans involving the heart. Policies can vary depending on the type of CT scan and whether contrast is used, so it's always best to follow specific instructions given by the healthcare provider or scan center.
