The amount of fluid intake recommended prior to an abdominal or pelvic imaging procedure utilizing sonography is a critical aspect of preparation. This hydration protocol is designed to optimize visualization of internal organs and structures during the examination. Typically, this involves consuming a specific volume of liquid within a defined timeframe leading up to the scheduled appointment. For example, patients may be instructed to drink 24-32 ounces of water one hour before the scan.
Adequate hydration distends the bladder, creating a clearer acoustic window through which the sonographer can view the uterus, ovaries, prostate, or other targeted anatomy. A full bladder acts as a natural contrast agent, displacing bowel gas and enhancing the quality of the images obtained. Historically, this preparation has been a standard practice to ensure diagnostic accuracy and minimize the need for repeat scans due to suboptimal imaging.
