Inclusion criteria
Inclusion criteria: Patients for whom spinal MRI was clinically indicated and who had previously undergone CT imaging of the same region. Patients for whom the target cortical bone imaging was successfully performed without issues.
Exclusion criteria
Exclusion criteria: - Individuals under 18 years of age - Individuals unsuitable for MRI examinations (e.g., those with pacemakers or other metallic implants, or those with claustrophobia) - Individuals who do not consent to participate in the study - Pregnant individuals or those who may be pregnant - Other individuals deemed unsuitable by the principal investigator or co-investigators
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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. | — |
Secondary
| Measure | Time frame |
|---|---|
| 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. | — |
