Interventional Radiology

Radiology is a medical specialty that employs the use of imaging to both diagnose and treat disease visualized within the human body. Radiologists use an array of imaging technologies (such as x-ray radiography, ultrasound, computed tomography (CT), nuclear medicine, positron emission tomography (PET) and magnetic resonance imaging (MRI)) to diagnose or treat diseases. Interventional radiology is the performance of, usually minimally invasive, medical procedures with the guidance of imaging technologies. The acquisition of medical imaging is usually carried out by the radiographer or radiologic technologist. The field of radiology is rapidly expanding due to advances in computer technology, which is closely linked to modern imaging.

PVD can result from atherosclerosis (ath-uh-roh-skluh-roh-sis), which is when fatty substances form a deposit of plaque on the inner lining of arterial walls, inflammatory processes leading to stenosis [sti-noh-sis], which is a narrowing or stricture of a passage or vessel, an embolism, which is the occlusion of a blood vessel by an embolus (undissolved material carried by the blood and impacted in some part of the vascular system, as thrombi or fragments of thrombi, tissue fragments, clumps of bacteria, protozoan parasites, fat globules, or gas bubbles), or thrombus (a clot that forms in and obstructs a blood vessel, or that forms in one of the chambers of the heart) formation. PVD causes either acute or chronic ischemia [ih-skee-mee-uh] (lack of blood supply).
The symptoms of PVD are:
• Claudication - pain, weakness, numbness, or cramping in muscles due to decreased blood flow
• Sores, wounds, or ulcers that heal slowly or not at all
• Noticeable change in color (blueness or paleness) or temperature (coolness) when compared to an unaffected limb
• Diminished hair and nail growth on affected limb and
