Over kan akımının değerlendirilmesinde transabdominal superb mikrovasküler görüntüleme ve konvansiyonel doppler görüntüleme tekniklerinin karşılaştırılması

Amaç: Bu çalışmada, transabdominal Superbmikrovasküler görüntüleme (SMG), color Doppler (CD) ve power Doppler (PD) görüntüleme yöntemlerinin sağlıklı gönüllülerde intraovarianvaskülariteyi saptamada etkinliği karşılaştırılmıştır. Gereç ve Yöntem: Çalışmaya yaşları 0 – 34 arasında olan 81 sağlıklı gönüllü (n = 162over) dahil edildi. Tüm katılımcılar transabdominal B-modultrasonografi, CD, PD ve SMG ile ayrı ayrı incelendi. Over hacimleri B-mod ultrasonografi ile ölçüldü, ardından CD, PD, SMG (cSMG) ve monokrom SMG (mSMG) yoluyla over kan akımları değerlendiriledi. Bulgular: SMG, over dokusunda düşük hızlı kan akım sinyallerini saptamada CD ve PD'den daha etkiliydi (p> 0.001). CD, PD, cSMG ve mSMG'deki ortalama ovaryanvaskülerite skoru sırasıyla, 0,5 ± 1, 1,8 ± 1,5, 3,3 ± 1,3 ve 4,3 ± 0,9 idi.Over hacimleri ve sağlıklı gönüllülerin yaş ortalaması azaldıkça, mSMG ve cSMG yöntemleri konvansiyonel Doppler tekniklerine göre overvaskülaritesini daha iyi gösterdi. Sonuç: Transabdominal SMG, overvasküleritesini diğer konvansiyonel Doppler tekniklerine kıyasla daha ayrıntılı göstermektedir. SMG, özellikle çocuk hastalarda overvasküleritesinin değerlendirilmesi için inceleme protokolünün bir parçası olmalıdır.

Objective: This study aimed to compare transabdominal Superb microvascular imaging (SMI), color Doppler (CD), and power Doppler (PD) with respect to their ability to detect intraovarian vascularity in healthy volunteers. Material and Methods: Eighty-one healthy participants (n = 162 ovaries) aged 0–34 years were included in the study. All participants were examined by transabdominal B-mode sonography, CD, PD, and SMI. Ovarian volumes were measured on B-mode sonography, followed by measurement of ovarian blood flow via CD, PD, color SMI (cSMI), and monochrome SMI (mSMI). Results: SMI was more efficient than CD and PD in detecting flow signals in the ovarian tissue (p > 0.001). The mean OVS in CD, PD, cSMI, and mSMI was 0.5 ± 1 (range, 0–5), 1.8 ± 1.5 (range, 0–5), 3.3 ± 1.3 (range, 0–5), and 4.3 ± 0.9 (range, 1–5),respectively. As the ovarian volume and participant age decreased, mSMI and cSMI showed significantly greater ability to depict vascularity in comparison with conventional Doppler techniques. Conclusion: Transabdominal SMI provides more detailed vascular information regarding ovarian blood flow than both CD and PD. SMI should be a part of the examination protocol for assessment of ovarian vascularization, especially in pediatric patients.
