Non Invasive Vascular Lab Jonathan Levison, MD on Non Invasive Vascular Lab The Non Invasive Vascular Lab of The Cardiovascular Care Group serves to diagnose problems of the arterial and venous system using completely noninvasive techniques without radiation exposure. We are able to identify blockages in arteries of the legs, abdomen and neck thereby aiding in the diagnosis of diseases such as peripheral artery disease (PAD), carotid artery disease (stroke prevention), abdominal aortic aneurysm (AAA) and renal artery (kidney) disease. Additionally, we are able to identify the causes of varicose veins using ultrasound technology that affords us the ability to direct therapy appropriately and identify life-threatening conditions such as deep vein thrombosis (DVT). The Non Invasive Vascular Lab was one of the early labs to be accredited in New Jersey by the ICAVL accrediting body and has remained accredited for nearly two decades! Our physicians and technologists are some of the most respected in the country and teach many others their learned skill.
