Aortic Diseases - Do We Need MR Techniques?

Abstract

MR with its various imaging protocols including spin-echo MR-imaging, gradient MR imaging, flow-mapping and MR angiography is the ideal tool for noninvasive assessment of any kind of aortic diseases. The technique allows to image the aorta both in the thoracic cage and in the abdominal aspects better than any other tomographic image modality. With the capability of angiography after intravenous injection of gadolinium even the information previously only obtained from invasive catheter-based studies is now available within minutes after an intravenous injection. The overview manuscript compares various clinical settings of aortic diseases as assessed by various imaging modalities and highlights the capability of MR-imaging for aortic diseases both in the chronic and the acute clinical setting.

Suspected Aortic Dissection and Other Aortic Disorders: Multi–Detector Row CT in 373 Cases in the Emergency Setting

“…Penetrating aortic ulceration, a disorder associated with increased risk of progression to acute aortic rupture and other acute aortic disorders, has an unknown independent prevalence but has been reported in association with 2.3% of cases of suspected aortic dissection and is associated with 52% of aortic intramural hematomas (9,10). A delayed or missed diagnosis of acute aortic dissection, and possibly acute aortic intramural hematoma, when untreated, is associated with a mortality rate of greater than 1% per hour during the first 24 hours after onset and of 80% by 2 weeks (11,12).…”

A sneeze: an unusual trigger for aortic dissection

“…Systemic hypertension is the most common predisposing factor for AD followed by atherosclerosis and advanced age 4. Other risk factors include collagenous vascular diseases, bicuspid aortic valves, infective aortopathies and pregnancy 3.…”

Torasik Travma

“…Bununla birlikte, son teknolojik gelişmelerle yüksek çözünürlüklü MRG ile aortun görüntüleme-sinde önemli ilerlemeler kaydedilmiştir [14]. MRG, günümüzde muhtemelen KAY teşhisi için bir sorun çözme aracı olarak kullanılmaya devam edecektir.…”
