Head MRI protocol – recommendations of the Polish Medical Society of Radiology and the Polish Society of Neurology

Electromagnetic field	Images should be of good quality with an appropriate SNR value and resolution (≤ 1 × 1 mm)
Reference setting	When setting the scanning plane, use a line parallel to the lower edges of the rostrum and splenium of the corpus callosum; also, have an identical angulation of the planned slices to that of the slices in the previous study
Scanning range	Whole brain scanned
Slice thickness and gaps	≤ 3 mm, with no gaps (for 2D and 3D acquisition)
Basic sequences	1. 3DT1 axial isotropically 2. T2 axial 3. DWI axial (with ADC map) Administration of a contrast medium 1 (T1 sequence 5-10 minutes after administration). The recommended dose of a contrast medium is 0.1 mmol/kg body mass 4. FLAIR+C sagittal 5. FLAIR+C axial 6. 3DT1+C axial isotropically
Optional sequences	1. PD 2. SWI – to identify central veins in lesions and microbleedings 3. DIR – to evaluate cortical and subcortical foci

SNR – signal-to-noise ratio
