Multiphase time-resolved contrast-enhanced portal MRA in normal dogs

摘要: Portal vein anomalies are common in dogs and cats. Diagnostic imaging is central their diagnosis fundamental with regard to choosing the best therapeutic option. Various techniques used veterinary medicine assess portal vein. Each has individual advantages disadvantages. Contrast-enhanced magnetic resonance angiography (CE-MRA) routinely humans image system excellent spatial temporal resolution three-dimensional (3D) acquisition. Herein, we report development of a CE-MRA protocol that resulted fast 3D arterial splanchnic venous normal dogs. Multiphase acquisition strategy allowed acquiring same volume several times during one single breath-hold, thereby capturing phase signal. Excellent depiction vascular anatomy, especially afferent vessels branches, was observed. Elliptical centric view ordering k-space acquire contrast-sensitive data faster. Parallel increase coverage dorsal ventral direction while keeping time short. It anticipated noninvasive method could be diagnose various small animals.
