1. 3 types of procedures used in the medical field Maria Sosa

2. Cardiac CT cardiac scan Cardiac CT (cardiac computed tomography) is a test intended to look for problems in the heart. This painless x-ray machine uses a circular object that moves around the body emitting radiation to create a three-dimensional picture of the entire heart. Sometimes a contrast dye (iodine based dye) is needed to highlight certain part of the hear, for example in the case of coronary heart disease (CHD). The x-ray picture can show whether the coronary arteries are narrowed or blocked. Overexposure of radiation can cause cancer but this is prevented by following the rules and using the appropriate equipment prior to using the x-ray machine.

4. Doppler ultrasound The Doppler ultrasound is a test that uses high frequency sound waves (ultrasound) to measures how blood flows through the blood vessel. Most common sites of seeing the blood moment are the arms, neck, and legs. This test helps to show blockage or narrowing of vessels. it also detects injuries to arteries and it can also monitor certain treatments to your veins and arteries.

6. PTAC Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that restores normal blood flow to any blocked or narrow artery. This procedure is mainly done in people that have coronary artery disease (CAD). This disease causes a fatty tissue to compact around the walls of the coronary arteries. Making it extremely impossible for the passage of oxygen-rich blood to supply the heart muscle. The way that this procedure works is by inserting a catheter into the narrow or blocked artery. Once the catheter is in place the small balloon on the tip of the catheter that gets inflated. The inflation of the balloon widens the artery and compresses the fatty tissue to the sides.
