What Is Angiopgraphy?
Angiography is one of several interventional radiology procedures used by physicians at Portsmouth Regional Hospital to diagnose heart or vascular disease precisely.
Benefits To You
Angiography, a nonsurgical imaging technique, uses X-rays to look inside arteries, veins or other organs. The image area is highlighted using a special dye injected through a flexible catheter inserted into the groin or arm and threaded through the body.
Health Risk Assessments

When someone experiences a stroke, a radiologist working with the Portsmouth emergency team can use angiography to pinpoint the site of the blockage or hemorrhage so clot-dissolving drugs can be injected quickly to restore blood flow and prevent damage to brain tissue.
Our specialists also assess blood flow to the heart muscle with CT coronary angiography to diagnose suspected coronary heart disease.
What to Expect
In our Cardiac Catheterization Lab, we perform angiography with sedation under the supervision of a cardiologist assisted by a qualified nurse and technician. The nurse makes sure you're relaxed and comfortable throughout. Depending on what the cardiologist finds, the procedure takes 45 to 90 minutes. After we remove the catheter, you'll need to remain flat and quiet for four to six hours.
The Radiation Right safety program at Portsmouth Regional Hospital, where we adhere to nationally approved safety protocols that prevent accidental or excessive exposure, ensures you receive the lowest effective dose of radiation.
