| - | The protocol below represents a full brain exam. There is variation depending on the clinical question and clinician preference. The **minimum** recommended sequences are in bold text. Note that some sequences such as the DWI have specific use cases and should be considered required if their indication is present, ie if an ischemic stroke is the clinical question, don't skip the DWI. | + | The protocol below represents a full brain exam.

It is highly suggested to acquire at last one post contrast series with fat saturation. |

| + | * It can be difficult to acquire diagnostic DWI on small brains with older Siemens scanners, as the smallest FOV possible can be on the order of 180-200mm. | ||
| + | * Try to use a flex coil, or flex + spine coil; this will enable the use of grappa and help with SNR | ||
| + | * Use low resolution; <128, grappa set to 2, and increase averages to 4-8. This may also allow for a smaller FOV. | ||
