“…Recently, it was shown that using the heavily T1‐weighted sequence on MRI could increase the reliability of detection of intramural hematoma compared with using the T1‐fat saturation method, which could improve the accuracy of vertebral artery dissection diagnosis . In aortic dissection, multi‐detector row CT is the modality of choice for imaging acute aortic syndrome with a sensitivity and specificity approaching 100% …”

Background This study aims to investigate the etiology and prognosis of spinal cord infarction (SCI). Methods Over a period of 16 years, we retrospectively analyzed 31 patients with SCI. Demographic features and symptom presentations were carefully documented. Etiology‐specific MRI features, such as the length and distribution of the lesions and owl’s eyes sign, were recorded and analyzed to determine their associations with the clinical signs/symptoms. Results In total, seven patients had aortic or vertebral artery dissections. We divided the patients with SCI into two groups: those with or without vessel dissection. Among SCI patients, the onset age was younger, and the proportion of patients with long‐segment lesions and posterior pattern involvement on axial view was higher in the group with dissection than in the group without dissection (all P < 0.05). The lesions were frequently located in the upper cervical or lower thoracic‐lumbar regions, and the lengths of the lesions were associated with 1‐month outcomes, suggesting that artery dissection may contribute to the longitudinal and posterior extension of SCI. In contrast, among patients without dissection, the range of longitudinal extensions of in spans of vertebral bodies was broader (range, 1–8). A higher proportion of patients had focal pain adjacent to the lesion (P = 0.05) and a poorer 1‐month outcome (P = 0.04) in the long‐segment lesion group than in the short‐segment lesion group. Conclusions A detailed history and the use of modern imaging tools may help clinicians search for vessel dissection and other etiologies, evaluate the spatial extension of lesions in SCI, and predict prognosis.

High-end scanners with 128 or more rows 9) also have the potential to shorten the scan duration, improve spatial resolution, and/or scan an organ in a single gantry rotation without moving the patient s table.…”

Computed tomography (CT) is a primary imaging modality for the diagnosis of aortic diseases, because of its minimal invasiveness and agility. Prompt and accurate diagnosis is crucial especially for acute aortic diseases, and the guidelines for acute aortic dissection recommend the use of CT for initial diagnosis. For the follow-up observation of longstanding aortic diseases, the strategy of imaging management by CT must be different from that for emergency and acute phases. In this review, we document the differences in characteristics and clinical course between aortic aneurysm and aortic dissection and explain the use of recent CT techniques in diagnosing short-and longstanding aortic diseases.

Acute aortic pathologies include acute aortic syndrome (aortic dissection, intramural hematoma, penetrating aortic ulcer), impending rupture, aortic aneurysm rupture and aortic trauma. Acute aortic syndrome, aortic aneurysm rupture and aortic trauma are life-threatening conditions requiring prompt diagnosis and treatment. The basic imaging modality for "acute aorta" is CT angiography with typical findings for these aortic pathologies. Based on the CT, it is possible to classify aortic diseases and anatomical classifications are essential for the planning of treatment. Currently, endovascular treatment is the method of choice for acute diseases of the descending thoracic aorta and is increasingly indicated for patients with ruptured abdominal aortic aneurysms.
