“…In our study, even if the percentage of intima-media thickness > 1 mm was lower in study group (61.8%) respect to control group (78%), the analysis of age distribution showed that intima-media thickness > 1 mm was most represented in lower age-classes (35-45 and 45-55) of study group than in control group. These results, according to Koyuncu et al [15], could suggest a vascular etiology of vertigo in these age-classes (35e55 years). The last evaluated imaging findings were peak systolic and resistive index as calculated within the vertebral arteries.…”

Introduction: To evaluate the utility of echo-color-Doppler ultrasonography (CDU) of extracranial brain-supplying vessels in patients with peripheral vertigo of unknown origin. Materials and methods: One-hundred-fifty-six patients (study group; 42 male and 114 female; mean age 61.86 AE 14.14) and 161 patients (control group; 80 male and 81 female; mean age 62.31 AE 13.69) were prospectively evaluated with CDU of extracranial brain-supplying vessels. Plaques in common and/or internal carotid artery (CA), arterial wall intima-media thickness (IMT) of common CA and peak systolic velocity (PSV) and resistive index (RI) of vertebral arteries (VA) were evaluated. Parametric (t-test) and non-parametric (ManneWhitney U-test and KolmogoroveSmirnov test) tests were applied. Logistic regression analysis was performed to provide odds ratio indicating the magnitude of risk of vertigo. Independent variables consisting of characteristics (age, sex), vascular risk factors (hypercholesterolemia, diabetes, hypertension) and CDU variables (IMT, plaque, PSV and RI of VA) were considered. Results: Plaques were found in 31 (19.8%) patients of study group and in 43 (26.7%) patients of control group. IMT > 1 mm was found in 98 (62.8%) patients of study group and in 125 (77.6%) patients of control group.Statistical tests, applied to PSV and RI, showed no significant difference (p-value >0.05). At logistic regression analysis, vertigo was associated with age, sex, hypercholesterolemia, diabetes, hypertension and IMT (p < .01) while plaque, PSV and RI of VA were not significant factors (p > .05). Discussion: IMT is the only CDU variable significantly associated with vertigo, especially in the lower age-classes (35e45 and 45e55) of study group.Sommario Introduzione: Valutare l'utilità dell'eco-color Doppler (CDU) dei vasi epiaortici nei pazienti con vertigine periferica da causa sconosciuta.

“…All 11 patients complained of dizziness, vertigo, unsteadiness, or feeling faint, symptoms attributable to secondary chronic cerebral circulation impairment as sequelae of brain infarction. Others who studied the relationship between dizziness and the regional CBF demonstrated hypoperfusion in both occipital lobes and posited that insufficient flow in the territory of the vertebrobasilar system is a factor resulting in hypoperfusion of both occipital lobes [22,23]. At 2 and 6 months after the start of ibudilast therapy, all of the 11 patients reported resolution of their dizziness episodes.…”

“…Several studies have shown that SPECT was superior to MRI and CT in detecting perfusion abnormalities in patients with vertigo. 22 Our previous study found detection rates of 74, 58, and 48%, respectively, in patients with vertigo ." In our present study, however, we found that MRI was superior to SPECT and CT in this regard, with detection rates of70,26,and 21%, respectively (table 2).…”

We conducted a retrospective study to reexamine the value of singl e-photon emission computed tomography (SPECT) in the evaluation of patients with neurotologic complaints, and to assess the intra-and inter-radiologist variability ofSPECT readings. Ourstudypopulationwas made up of63 patients-23 men and 40 women, aged 34 to 91 years (mean: 59)-who had presented to a tertiary care otolaryngology practice and universit y hospital for evaluation of head trauma, sensorineural hearing loss, tinnitus, and/or vertigo. All patients had undergone brain scanning with SPECTduringtheirevaluation, and almost allhad also undergone magneticresonance imaging(MRI) and standardcomputed tomography (CT). We compared thefindings of all three imagingmodalities in termsof theirabilitytodetect neurotologic abnormalities. We found that detection rates were very similar among the three modalities; abnormalities were found in 24% of SPECTscans, 26% of MRIs, and 23 % of CTs. Nevertheless, we didfind that among 60 patients who underwent all three types of imaging, 13 (22 %) exhibited areas of
