Kalsifiye ostial plak ve blooming taklitçisi

Özet

Ostial kalsifik plakta kalsiyum blooming’i BT anjiyografide stenoz derecesinin olduğundan fazla değerlendirilmesine yol açabilir. Ostial darlığın değerlendirilmesinde ince kesitli BT anjiyografi ile merkez çizgisi ve eğrisel MPR üzerinden damar çapı ölçümleri kullanılabilir.

Faz ve pencere

BTA tanısal

Kalsifik damarların BT anjiyografik değerlendirmesinde daha yüksek uzaysal çözünürlük kalsiyum blooming’ini azaltabilir ve stenoz ölçümünü etkileyebilir.

Önerilen pencereler: Anjiyo (G 600 / M 150), Batın (G 400 / M 50).

BT bulguları

• Yoğun ostial kalsifik plakta kalsiyum blooming’i BT anjiyografide stenoz derecesinin olduğundan fazla değerlendirilmesine yol açabilir.
• Renal arter ostiumu ve çevresindeki damar anatomisi, BT’de multiplanar ve 3D rekonstrüksiyonlarla değerlendirilir.

Normalde

Ostial kalsifik plak değerlendirilirken kalsiyum blooming’inin stenoz derecesinin olduğundan yüksek ölçülmesine yol açabileceği göz önünde bulundurulmalıdır.

Ayırıcı tanı

Renal arter fibromüsküler displazisinde klasik “boncuk dizisi” örüntüsü görülebilir; ostial aterosklerotik darlık farklı bir örüntüdür.

Hareket artefaktı

damar konturunu kesitler arasında bulanıklaştırabilir; darlığın anatomik sürekliliğini başka düzlemlerde kontrol edin.

Tuzaklar

• Kalsifikasyonu değerlendirmek için önce aksiyel kaynak görüntüleri incele; damar çapı ve uzunluğunu merkez çizgisi ve eğrisel MPR ile değerlendir.
• Kalsiyum blooming’i BT anjiyografide kalsifik damar darlığının olduğundan fazla ölçülmesine yol açabilir.
• Ostial kalsifik plakta kalsiyum blooming’i BT anjiyografide stenoz derecesinin fazla değerlendirilmesine yol açabilir; uzaysal çözünürlüğün artırılması blooming etkisini azaltabilir.

Kendini dene

1. BT anjiyografide damar çapı ve uzunluğunu ölçmek için hangi yaklaşım kaynakta önerilmektedir?

   • Önce aksiyel kaynak görüntüleri inceleyip ardından merkez çizgisi ve eğrisel MPR kullanmak
   • Yalnız 3B hacim görüntüsünden ölçüm yapmak
   • Aksiyel kaynak görüntüleri incelemeden yalnız MIP kullanmak
   • Damar ölçümü yerine kalsiyum sınırını damar çapı kabul etmek
