PETALUTE: Dynamic MRI Video of Hyperpolarized Pyruvate Signal Propagation in a Phantom

A video file from the Biomedical Research Imaging Center at UNC-Chapel Hill, acquired on a 9.4T Bruker MRI scanner. The dataset shows a dynamic PETALUTE imaging sequence capturing approximately 10 seconds of signal propagation following a hyperpolarized [1-¹³C]pyruvate injection into a phantom. The data was uploaded by author Megan Pike in April 2026.

Use Cases

• Visualizing the temporal propagation of a hyperpolarized agent based on the real-time video capture.
• Benchmarking custom MRI pulse sequences like PETALUTE based on the described acquisition method.
• Studying hyperpolarized signal decay dynamics based on the described 10-second detectable signal window.

Strengths

• Data acquired on a high-field 9.4T MRI scanner, suggesting high signal-to-noise potential.
• Captures a specific temporal window of approximately 10 seconds for hyperpolarized signal dynamics.
• Uses a custom-developed PETALUTE pulse sequence for specialized imaging.

Limitations

• The dataset is a single 2.1 MB MP4 video; scale and sample diversity are limited.
• Row count and column-level documentation are absent; data structure must be inferred from the video.
• Description metadata is limited; actual data quality requires manual inspection after download.
