cystography

Cystography is a medical imaging technique used to examine the urinary bladder. It involves introducing a radiopaque substance, often an organic iodine derivative, into the bladder. This contrast fluid allows the bladder to be visualized using X-rays.1

Cystography can help detect various conditions, including tumors, and can be used in conjunction with other imaging methods like CT scans or MRIs for a more comprehensive diagnosis, particularly in cases of suspected bladder cancer. A specific type, known as a voiding cystourethrogram (VCUG), is important for investigating urinary tract infections in children and can reveal if urine flows backward into the ureters or kidneys during urination.123
