Some states award delegates to candidates on a winner-take-all basis, meaning that the candidate with the most votes in a state is awarded all of that state's delegates. Other states award delegates in proportion to each candidate's share of the primary vote.
Provocative angiography involves a full diagnostic angiogram followed by administration of intra-arterial procoagulant agents to identify an occult bleeding source in patients who have normal test results after lower gastrointestinal bleeding.
An angiogram is an X-ray test that uses a special dye and camera (fluoroscopy) to take pictures of the blood flow in an artery (such as the aorta) or a vein (such as the vena cava). An angiogram can be used to look at the arteries or veins in the head, arms, legs, chest, back, or belly.uring an angiogram, a thin tube called a catheter is placed into a blood vessel in the groin (femoral artery or vein) or just above the elbow (brachial artery or vein). The catheter is guided to the area to be studied.
