“…TOF angiography technique allows imaging without the use of gadolinium contrast. The accuracy of the TOF MRA with fat-suppressed T1 images is comparable to CE MRA for detection of cervical dissection, which can be of value in patients with renal insufficiency [51]. Depending on the surrounding structures, such Fig.…”

Headaches from vascular causes need to be differentiated from primary headaches because a misdiagnosis may lead to dire consequences for the patient. Neuroimaging is critical in identifying patients with vascular headaches and identifying the nature of the pathologic disorder causing these headaches. In addition, the imaging findings guide the physician regarding the optimal treatment modality for these lesions. This review summarizes the nuances of differentiating patients with secondary headaches related to vascular disease and discusses pertinent neuroimaging studies.

“…The advantage of СЕ MRA and TOFMRA in comparison to DSA is readily available extension of the study with Т2 f/s and Т1 f/s WIs with focus on stenotic portion of the artery to prove or to exclude dissection. Combination of MRI and MRA provides not only effective diagnostics of dissection, but it also can be used as non-invasive approach to monitor IMH regress over time or development of complications [16].…”

BackgroundWithin the last 10 years we observe the trend towards the decrease of the age of cerebrovascular diseases victims, and stroke morbidity and mortality in individuals of economically active age group increased for over 30% [1,2]. In young and middle-aged patients major causes of stroke differ from those in elderly population, as they are represented by cardiac embolism and spontaneous dissection of the

“…Invasive digital subtraction angiography (DSA) has been the gold standard for clinical decision-making during the past years ( 13 ). Recently, advanced high-resolution magnetic resonance imaging (hrMRI) offers excellent visualization of both the arterial wall and lumen, enabling the detection of multi-features of EVAD ( 10 , 14 , 15 ). However, both of them are time-consuming.…”

ObjectiveExtracranial vertebral artery dissection (EVAD) is one of the main causes of stroke in young and middle-aged patients. However, the diagnosis is challenging. This study aimed to identify the characteristics of EVAD on color duplex ultrasonography (CDU) and high-resolution magnetic resonance imaging (hrMRI), hoping to improve the accuracy and determine the relative contribution of vessel findings and clinical factors to acute ischemic events.MethodsPatients with unilateral EVAD were recruited and divided into ischemia and non-ischemia groups. Clinical features of patients and the lesion location; a variety of signs which indicate dissection, including the presence of an intimal flap, double lumen, intramural hematoma, dissecting aneurysm, intraluminal thrombus, and irregular lumen; and other quantitative parameters of each dissected segment on CDU and hrMRI were reviewed, respectively. Multiple logistic regression was performed to explore the association between clinical, imaging characteristics, and ischemic events in patients with unilateral EVAD.ResultsNinety-six patients with unilateral EVAD who met the inclusion criteria were enrolled during a six-year period. Overall, 41 cases (42.7%) were confirmed as ischemic stroke (n = 40) or transient ischemic attack (n = 1) during the 48 h after the onset of symptoms. Men, infections during the last week, and smoking were more common in the ischemia group. Intraluminal thrombus and occlusion on CDU were more prevalent in patients with cerebral ischemia than in those without (36.6 vs. 5.5%; p < 0.001, and 39.0 vs. 9.1%; p = 0.001, respectively). On hrMRI, intraluminal thrombus and occlusion were also more frequent in the ischemia group than in the non-ischemia group (34.1 vs. 5.5%; p < 0.001, and 34.1 vs. 9.1%; p = 0.003, respectively). In addition, lesion length on hrMRI was significantly longer for patients with ischemia (81.5 ± 41.7 vs. 64.7 ± 30.8 mm; p = 0.025). In multivariable logistic regression analysis, male gender, infections during the last week, and the presence of intraluminal thrombus on CDU and hrMRI were independently associated with acute ischemic events.ConclusionMale sex, infections during the last week, and the presence of intraluminal thrombus due to dissection are associated with an increased risk of ischemic events in patients with unilateral EVAD.
