 Abstract: Time-resolved volumetric imaging (4D-MRI) of moving organs is essential for several clinical applications, e.g., in interventional treatments, radiation therapies, and high-intensity focused ultrasound ablations. In this work, an interleaved time-resolved data-navigator acquisition strategy for 4D-MRI with flexible contrast is developed offering versatile settings for thoracic and abdominal imaging: for both, image and navigator, not only the flip angle but also the basic acquisition type (pulse sequence kernel) can be chosen independently from either balanced SSFP (i.e., T2/T1-weighted) or spoiled gradient echo (i.e., T1-weighted).
