What Are MRI Head Pictures?
Mri head painting, technically know as Magnetized Resonance Imaging, are cross-sectional images make by a knock-down magnetic battlefield, radio undulation, and a reckoner scheme. Unlike X-rays or CT scans, which are splendid for os structures, an MRI excels at highlighting soft tissue point. This countenance radiologists to see the nous, blood watercraft, and nervus with unbelievable precision.

|---|---|---|
| T1-Weighted | Soma | Fluid (CSF) seem dark; fat appear bright. |
| T2-Weighted | Pathology/Inflammation | Fluid (CSF) appears brilliant; full for realize neoplasm or intumesce. |
| FLAIR | Edema/Lesions | Fluid is suppressed; brilliant place spotlight unnatural tissue. |
