An IVUS image of the ostial left main coronary artery (left). The blue outline delineates the cross-sectional area of the lumen of the artery (A1 in the upper right corner), measuring 6.0 mm 2. A two-dimensional mapping of the proximal LAD and left main coronary arteries is shown on the right.
An intravascular ultrasound image of the ostium of the left main coronary artery. Intravascular ultrasound, also known as a percutaneous echocardiogram is an imaging methodology using specially designed, long, thin, complex manufactured catheters attached to computerized ultrasound equipment to visualize the lumen and the interior wall of blood ...
The catheter is threaded into an artery in the forearm, and the tip is advanced through the arterial system into the major coronary artery. X-ray images of the transient radiocontrast distribution within the blood flowing inside the coronary arteries allows visualization of the size of the artery openings .
Carotid endarterectomy: A carotid endarterectomy is a minimally invasive procedure to remove plaque from within your carotid artery, the main blood vessel that carries blood to your brain.
One of its main applications is for coronary arteries, which are often treated by endoscopic, minimally invasive surgical procedures. [2] Other applications for peripheral arteries and for neurovascular procedures have been proposed and are being investigated. Neurovascular applications required significant technological developments, due to ...
The coronary arteries can constrict as a response to various stimuli, mostly chemical. This is known as a coronary reflex. There is also a rare condition known as spontaneous coronary artery dissection, in which the wall of one of the coronary arteries tears, causing severe pain. [10]

The image is taken in with the x-ray tube in left anterior oblique position. [8] To image the vessels of the neck such as common carotid, internal and external carotid arteries, AP, lateral, and 45 degrees bilateral oblique positions are taken. Contrast injection rate is 3 to 4 ml/sec with total volume of 7 to 9 ml.
