Doctors may look for signs of narrowed, enlarged or hardened arteries by performing a physical examination. If<unk>  is present, there will be a weak or even absent pulse under the narrowed area of the artery. The<unk>  pressure in the affected limb would be lowered and whooshing sounds can be heard over the affected arteries using a stethoscope. After that, the following tests could be adapted to further locate the point of narrowing or enlargement of<unk><unk> s. Angiography showing blockade of coronary artery Angiography Angiography is a medical imaging technique used to visualize the lumen of<unk><unk> s. A catheter, which is a long and thin tube, is inserted into a large artery in the arm or groin area. It is then guided along the artery to the targeted<unk><unk>  to be examined. An imaging dye is loaded into the<unk><unk>  through the catheter and the movement of the dye in the<unk><unk>  is recorded as an angiogram. Doctors could determine if there are any abnormalities in the<unk><unk>  using fluoroscopy, computed tomography (CT) angiography or magnetic resonance (MR) angiography. After the catheter is removed, some pressure is applied to the incision site for 10 to 20 minutes to prevent excessive bleeding. Vascular ultrasound Vascular ultrasound is a non-invasive imaging method to examine the circulation inside<unk><unk> s. Sound waves are transmitted through the tissues of the targeted area and they reflect on the<unk>  cells moving within<unk><unk> s. The waves recorded are displayed as an image of the<unk><unk>  and the speed of waves detected can be used to calculate the speed of<unk>  flow inside the<unk> . When the rate of<unk>  flow is too low, there may be a blockage of<unk> . By evaluating<unk>  flow in<unk> s, the severity and specific location of<unk>  can be determined.
