To exploratively evaluate the characteristics, appropriate clinical applications, and pitfalls of various cortical bone imaging techniques in the spinal region.
Others
Traditionally, the evaluation of cortical bone and calcifications has been challenging with MRI due to their extremely short T2 values, and CT has been the primary modality used. However, recent advancements have introduced cortical bone imaging (CT-like imaging) techniques, including zero TE, ultra-short TE, 3D multi-gradient echo, and AI-driven MRI-based synthetic CT, enabling cortical bone assessment using MRI. This development offers the potential to simultaneously evaluate soft tissues and bone morphology with MRI alone, promising improved clinical efficiency and economic benefits. However, the characteristics, optimal applications, and pitfalls of each technique remain unclear, limiting their clinical adoption. This study aims to capture spinal region images using these cortical bone imaging techniques and conduct an exploratory evaluation of their features and appropriate clinical applications.
Exploratory
Pragmatic
Not applicable
In newly acquired spinal MRI cortical bone imaging, a visual scaling evaluation will be performed by multiple reviewers. This evaluation will assess the presence and extent of lesions, anatomical structures, artifacts, and noise levels. The results will be compared with CT examinations of the same patients and the same regions.
To support the primary evaluation metrics, the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) will be calculated for each sequence, and these quantitative values will be compared and analyzed.
