An intravenous pyelogram (PIE-uh-low-gram), also called an excretory urogram, is an X-ray exam of your urinary tract. An intravenous pyelogram lets your doctor view your kidneys, your bladder and the tubes that carry urine from your kidneys to your bladder (ureters). An intravenous pyelogram may be used to diagnose disorders that affect the urinary tract, Read more…

Intrauterine insemination (IUI) — a type of artificial insemination — is a procedure for treating infertility. Sperm that have been washed and concentrated are placed directly in your uterus around the time your ovary releases one or more eggs to be fertilized. Older types of artificial insemination placed the sperm in the vagina. While this Read more…

Intraoperative radiation therapy (IORT) is an intensive radiation treatment that’s administered during surgery. IORT allows direct radiation to the target area while sparing normal surrounding tissue. IORT is used to treat cancers that are difficult to remove during surgery and there is a concern that microscopic amounts of cancer may remain. IORT allows higher effective Read more…

Intraoperative magnetic resonance imaging (iMRI) is a procedure to create images of the brain during surgery. Neurosurgeons rely on iMRI technology to create accurate pictures of the brain that guide them in removing brain tumors and other abnormalities during operations. Advantages of iMRI Though doctors use imaging tests to plan brain surgery, real-time images created Read more…

An intragastric balloon is a newer kind of weight-loss procedure. A saline-filled silicone balloon is placed in your stomach, which helps you lose weight by limiting how much you can eat. It also makes you feel fuller faster. This procedure is an option if you’re overweight or obese, and diet and exercise haven’t worked for Read more…

Intensity-modulated radiation therapy (IMRT) is an advanced type of radiation therapy used to treat cancer and noncancerous tumors. IMRT uses advanced technology to manipulate photon and proton beams of radiation to conform to the shape of a tumor. IMRT uses multiple small photon or proton beams of varying intensities to precisely irradiate a tumor. The Read more…

In vitro fertilization (IVF) is a complex series of procedures used to treat fertility or genetic problems and assist with the conception of a child. During IVF, mature eggs are collected (retrieved) from your ovaries and fertilized by sperm in a lab. Then the fertilized egg (embryo) or eggs are implanted in your uterus. One Read more…

Image-guided radiation therapy (IGRT) is a method of radiation therapy that incorporates imaging techniques during each treatment session. Radiation therapy uses high-energy beams of radiation to control cancer and noncancerous tumors. By adding detailed images, IGRT ensures the powerful radiation is narrowly focused at the treatment area. When undergoing IGRT, high-quality images are taken before Read more…
