title: Arterial imaging.
abstract: Angioscopy, magnetic resonance angiography, computed tomography, and nuclear medicine are assuming an increasingly important role in arterial imaging.  This review discusses recent advances in these modalities.  Angioscopy has proven valuable in monitoring intraoperative surgical procedures as well as percutaneous interventions.  Carotid artery magnetic resonance angiography is gaining increasing acceptance in clinical practice.  Magnetic resonance angiography of the peripheral arteries is limited by spatial resolution and signal loss distal to the stenosis.  The role of computed tomography in limiting the number of aortograms performed in evaluating aortic laceration remains controversial; however, several recent papers indicate its usefulness in evaluating clinically stable patients with abnormal chest radiographs.  Computed tomography of abdominal aortic aneurysms may obviate the need for preoperative aortography in the majority of cases.  Nuclear imaging for deep venous thrombosis using  111In-labeled antifibrin monoclonal antibodies was shown highly sensitive in its initial report.
