Pulmonary Venous Anatomy Imaging With Low-Dose, Prospectively ECG-Triggered, High-Pitch 128-Slice Dual-Source Computed Tomography

Abstract

Using a high-pitch dual-source CT protocol, PV imaging can be performed with minimal radiation dose, short scan acquisition, and excellent image quality in patients with sinus rhythm or atrial fibrillation. This protocol highlights the success of new cardiac CT technology to minimize radiation exposure, giving clinicians a new low-dose imaging alternative to assess PV anatomy.
