A wide scope of imaging modalities including planar imaging, figured tomography (CT), MRI, ultrasound and more up to date methods, for example, PET are accessible. They are used in an assortment of mixes, contingent upon the data required and the nature and intricacy of the interventional methodology which is being arranged. Imaging approaches differ among focuses and regularly reflect neighbourhood ability. In most vascular patients, starting evaluation is embraced by duplex ultrasound, evading the requirement for ionizing radiation. Progressively, patients likewise go through pre- interventional appraisal utilizing attractive reverberation angiography, which is of specific worth in arranging intercessions in the aorta and iliac vessels. Multi-identifier line CT is the backbone for the arranging of endovascular stomach and thoracic aneurysm fix and in follow-up after stent–unite arrangement. Catheter angiography is presently to a great extent held for interventional techniques; angiography permits us to continue promptly to intercession, which can be basic in crisis circumstances like uncontrolled discharge
