В проспективное исследование включены 20 пациентов с дилатацией восходящей аорты (ВАо) (≥45 мм). Всем больным выполнена МСКТ- и МРТ-ангиография с электрокардиографической синхронизацией. На различных уровнях ГА в систолу и диастолу по внутреннему контуру сосуда определяли его средний диаметр (Dср) и площадь поперечного сечения (ППС). Все измерения выполнялись двумя врачами-рентгенологами. Каждый проводил измерения два раза с интервалом не менее 1 мес. Определяли воспроизводимость повторных измерений с использованием коэффициента внутриклассовой корреляции.</p></sec><sec><title>Результаты</title><p>Результаты. При анализе систолического кадра выявлены значимые различия между методами при измерении Dср (МРТ: 42,5 (41,0–47,8) мм; МСКТ: 37,7 (34,7–40,3) мм; р = 0,003) и ППС на уровне синотубулярного соединения (МРТ: 14,8 (12,7–17,9) см2; МСКТ: 11,4 (10,3–13,3) см2; р = 0,009), ППС ВАо (МРТ: 17,6 (14,6–20,8) см2; МСКТ: 19,6 (16,7–21,5) см2; р = 0,035) и Dср проксимальнее левой подключичной артерии (ЛПКА) (МРТ: 31,5 (31,0–34,0) мм; МСКТ: 31,7 (27,3–32,9) мм; р = 0,041). Для диастолического кадра достоверные различия между методами наблюдали при измерении ППС ВАо (МРТ: 17,0 (14,5–19,7) см2; МСКТ: 19,7 (15,3–21,8) см2; р = 0,025), Dср (МРТ: 30,5 (29,3–32,8) мм; МСКТ: 29,8 (27,1–31,3) мм; р = 0,05) и ППС проксимальнее ЛПКА (МРТ: 7,5 (6,9–7,9) см2; МСКТ: 7,4 (5,9–7,8) см2; р = 0,007), а также ППС на уровне левого предсердия (МРТ: 4,9 (4,2–5,0) см2; МСКТ: 5,1 (4,67–5,5) см2; р = 0,042). По результатам анализа для МСКТ-ангиографии была получена хорошая внутри- и межоператорская воспроизводимость измерений на всех уровнях ГА. По данным МРТ-ангиографии отмечалась сильная внутри- и межоператорская вариабельность в определении Dср и ППС на уровнях дуги и нисходящей аорты.</p></sec><sec><title>Заключение</title><p>Заключение. Площадь поперечного сечения аорты показала наилучшую внутри- и межоператорскую воспроизводимость и сопоставимость измерений между МСКТ- и МРТ-ангиографией.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to compare intra- and inter-operator reproducibility of thoracic aorta (ThAo) morphometric parameters, calculated by multislice computed tomography (MSCT) and magnetic resonance imaging (MRI).</p></sec><sec><title>Material and methods</title><p>Material and methods. The prospective study included 20 patients with ascending aorta (AAo) dilatation (≥45 mm). All patients underwent MSCT- and MRI-angiography in electrocardiogram-gated mode. Mean diameter (Dmean) and cross-sectional area (CSA) were measured at different ThAo levels in the systole and diastole along the inner contour of the vessel. All measurements were performed by two radiologists. Each of them took measurements twice at an interval of at least 1 month. The reproducibility of repeated measurements was studied using intraclass correlation coefficient.</p></sec><sec><title> Results</title><p> Results. The analysis of the systolic frame revealed significant differences between the methodsfor measuring Dmean (MRI: 42.5 (41.0–47.8) mm; MSCT: 37.7 (34.7–40.3) mm; p = 0.003) and CSA at the level of the sinotubular junction (MRI: 14.8 (12.7–17.9) cm2; MSCT: 11.4 (10.3–13.3) cm2; p = 0.009), AAo CSA(MRI: 17.6 (14.6–20.8) cm2; MSCT: 19.6 (16.7–21.5) cm2; p = 0.035) and Dmean at the level proximal to left subclavian artery (LSA) (MRI: 31.5 (31.0–34.0) mm; MSCT: 31.7 (27.3–32.9) mm; p = 0.041). For the diastolic frame, significant differences between the methods were observed when measuring AAo CSA (MRI: 17.0 (14.5–19.7) cm2; MSCT: 19.7 (15.3–21.8) cm2; p = 0.025), Dmean (MRI: 30.5 (29.3–32.8) mm; MSCT: 29.8 (27.1–31.3) mm; p = 0.05) and CSA at the level proximal to LSA (MRI: 7.5 (6.9–7.9) cm2; MSCT: 7.4 (5.9–7.8) cm2; p = 0.007), as well as CSA at the left atrium level (MRI: 4.9 (4.2–5.0) cm2; MSCT: 5.1 (4.67–5.5) cm2; p = 0.042). For MSCT-angiography, good intra- and inter-operator reproducibility of measurements at all ThAo levels was obtained. For MRI-angiography, there was a strong intra- and interoperator variability in determining Dmean and CSA at the levels of aortic arch and descending aorta.</p></sec><sec><title>Conclusion</title><p>Conclusion.
