During a coronary CT angiogram, advanced CT technology and injected dye are used to take high-resolution 3D images of your heart. The 3D pictures of the beating heart and major blood vessels are used to identify coronary artery blockages. From the 3D images, your health care team can see i...
You may also need a renal angiogram if a computed tomography (CT) scan or magnetic resonance imaging (MRI) didn't show your blood vessels clearly. How Is a Renal Angiogram Done? Here is what to expect when you go for a renal angiogram: Before the procedure: Follow all the instructions y...
In the chemical stress test, the patient is again injected with a radionuclide when the heartbeat rate reaches at its peak. The similar process of capturing pictures of the heart with the gamma camera goes on. This part of the procedure is referred as stress scan (similar to the readings t...
weeks, months, or even years. Some of the symptoms are the same as for COVID-19, while others are quite different. Nearly 1 in 5 people who've had COVID-19 have symptoms a month or longer after the infection. Among people who needed hospitalization, the stats go up to more than 30...

Angiogram:This imaging technique may involve an X-ray, MRA (magnetic resonance angiogram), or CTA (computed tomography angiography). Angiogram differs from other imaging techniques in that it also involves the injection of contrast dye into the blood to provide a detailed look at blood vessels and...

With higher sensitivity than specificity, CCT might induce unnecessary angiograms ("false positive CCT"). We sought to determine the patients and CCT findings associated with false positive CCT. Methods: Patients were prospectively referred to CCT with a 64-slice CT scan for suspected CAD. ...
056 How to reduce unnecessary angiograms when patients are initially evaluated by coronary CT for coronary artery disease?Introduction The impact of missing data (MD) on the validity of results, although often discussed, is not often investigated. Sensitivity analyses under different scenarios of non...
