The test is performed to find out the cause of fainting spells. A patient has to lie on the bed and is lifted up to different angles (from 30 to 60 degrees) while the machine monitors
● Blood pressure
● Electrical impulses in the heart
● Oxygen level
Te99 SPECT Nuclear Cardiac Scans It is an imaging test for heart and is a non-invasive procedure. The doctors will recommend this scan in order to learn about any underlying coronary heart disease or if the patient has suffered a heart attack in the past. During the procedure, radioactive tracers are injected into the bloodstream. The picture of the heart is then taken through a gamma camera which picks up a clear picture of your heart.
PET Scans for Myocardial Viability Studies -The PET scan is done to study myocardial blood flow in the heart. This is done to analyse the amount of damage in the heart after a heart attack. The scan helps doctors in deciding the treatment for a patient. This test is also done through radioactive tracers wherein the picture is taken through a PET camera.
Cardiac MRI: Cardiac MRI or Cardiac Magnetic Resonance Imaging (MRI)-It is a more specialised test to ascertain heart conditions and help doctors in deciding the treatment procedure ahead. It is usually done after some inconsistency is visible in a patient’s chest X-ray and CT Scans. This procedure is also done by injecting dye into your blood vessels. A patient will then be asked to lie down on a table and will be shifted to a tunnel-like machine which is called MRI.
Renal Perfusion Scans -This scan is done to study blood flow obstruction to kidneys. It helps the doctor in determining the narrowing of renal arteries in the case of renal artery stenosis.
Intravascular Ultrasound (IVUS)
It is a catheter-based imaging technology that provides an advanced view of a coronary artery from the inside-out. It generates a real-time cross-sectional image that helps to gather information about the
- Presence and extent of disease
- Plaque geometry and morphology
- Guidewire position during lesion crossing
- Stent position post-treatment
Optical Coherence Tomography (OCT) - It is a non-invasive imaging test that uses light waves to produce high-resolution intracoronary images. It has catheters with a single optical fiber that emits infrared light and use as an intervention tool for percutaneous coronary intervention (PCI) guidance.
