Magnetic resonance imaging apparatus, magnetic resonance imaging method, and magnetic susceptibility calculation program |
| abstract |
In MRI, a magnetic susceptibility is calculated with high accuracy by reducing accuracy degradation due to signal loss. [Solution] Acquire at least one echo reflecting spatial magnetic field inhomogeneity using MRI, calculate a complex image from the acquired echo, a low signal region mask representing a low signal region from the calculated complex image, high signal and fat content Three masks are calculated: a first high-signal region mask representing a region with a high rate and a second high-signal region mask representing a region with a high signal and a low fat content. When creating a susceptibility image from a frequency image or magnetic field image created from a complex image, the susceptibility of the region defined by the low signal region mask is set in the background and the region defined by the second high signal region mask is predetermined. A magnetic susceptibility image is calculated under the restriction of a specific value. [Selection] Figure 6 |
