Use common CT brightness patterns to recognize air, fat, muscle, blood, bone, and calcium. Notice why a noncontrast calcium scan makes calcium bright but does not fill the coronary artery lumen with dye.

Use what you learned in the previous lesson to solve real-world problems.

Identify the right atrium, right ventricle, left atrium, and left ventricle by their usual positions and wall thickness. Compare how the chambers look as you scroll from the base of the heart toward the apex.

Trace blood from the body into the right heart, through the lungs, into the left heart, and out through the aorta. Use the vena cavae, pulmonary arteries, pulmonary veins, and aorta as landmarks.

Use what you learned in the previous lesson to solve real-world problems.

Reason through why the heart needs its own surface arteries even though its chambers are full of blood. Locate the coronary artery openings at the aortic root and follow how they run over the heart muscle.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Follow the left main coronary artery as it divides into the LAD and circumflex arteries. Use the LAD’s path down the front groove and the circumflex’s path around the left atrioventricular groove to predict where calcium may appear.

Use what you learned in the previous lesson to solve real-world problems.

Follow the right coronary artery from the right side of the aortic root along the right atrioventricular groove. Recognize how the posterior descending artery helps define right, left, or codominant coronary circulation.

Match major arteries to the heart muscle they usually supply: LAD to the front wall and septum, circumflex to the side wall, and RCA often to the inferior wall and right ventricle. Use these territories to understand why the location of disease matters.

Use what you learned in the previous lesson to solve real-world problems.

Practice spotting coronary arteries on a noncontrast calcium scan by using their expected paths, surrounding fat, and slice-to-slice continuity. Distinguish a true coronary focus from a random bright speck by checking whether it follows an artery course.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Compare coronary calcium with common nearby look-alikes such as aortic wall calcium, aortic valve calcium, mitral annular calcium, ribs, and pericardial calcification. Decide whether a bright spot belongs to a coronary artery by using location, shape, and continuity.

Use what you learned in the previous lesson to solve real-world problems.

Reason from reduced coronary blood flow to chest pressure, shortness of breath, or exertional symptoms. Connect oxygen demand, limited supply, and reversible ischemia without needing to diagnose a specific patient.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Trace what happens when a coronary artery becomes suddenly blocked long enough to injure heart muscle. Link the blocked artery, the downstream territory, and the time-sensitive progression from ischemia to myocardial infarction.

Use what you learned in the previous lesson to solve real-world problems.

Reason through how ischemia or a heart attack can disrupt the heart’s electrical rhythm. Connect unstable rhythms such as ventricular tachycardia or ventricular fibrillation to collapse and sudden cardiac death.
