    Angiography is the x-ray imaging of blood vessels using a contrast agent (dye). The dye makes the blood vessels visible with an x-ray.

    In medicine, "imaging" is the term used for any method to take pictures of bones and organs inside the body. Many imaging modalities use x-ray radiation whichcan help your health care provider find the cause of a medical problem.

    The most common blood test, a Complete Blood Count (CBC), is done to get information on the number of red, white and platelet cells in the blood. It tells your medical team the state of your health.

    A renal nuclear medical scan is used to diagnose certain kidney diseases. It shows not only what the kidneys look like, but also how well they work. Your doctor can use this to pinpoint certain health issues much sooner than with other methods.

    Uroflowmetry is a diagnostic test used to measure the flow of urine during urination. The speed of urine flow is measured electronically and the flow rate is calculated as milliliters of urine passed per second. Both average and maximum flow rates can be measured.

    Cystometry, or cystometrogram, with a pressure flow study is part of urodynamic testing (or UDS). These tests measure how well the bladder functions. They help diagnose problems related to urine control. These can be incontinence, difficulty emptying the bladder, overactive bladder, obstructions or frequent infections.

    Contrast and Radionuclide Cystography tests are used to diagnose bladder problems. It helps your urologist see how well the bladder works, and to find the cause of infections or check for tumors or stones. It is a way to look closely at the bladder walls.

    Antegrade pyelography uses special contrast agent (dye) to produce detailed X-ray pictures of the upper urinary tract (kidney and ureter). It is commonly used to diagnose conditions including hydronephrosis, ureteropelvic junction (UPJ) obstruction and obstruction of the ureters.

    Called a VCUG or cystogram, this test shows your doctor the size of your bladder and how well it can drain. The test is also used to pinpoint anything abnormal about the urethra and the bladder. For example, it can find a problem with the narrowing of the urethra (stricture ) or help uncover VUR (vesicoureteral reflux ), a condition in which urine flows back up from the bladder through the ureter and into the kidney.

    Also referred to as bladder scan, radionuclide cystogram is a diagnostic nuclear test that uses a solution containing radioactive material to outline the bladder to diagnose conditions such as reflux, distention or incomplete emptying.
