Methods and materials
58 patients with intracranial metastases,
aged between 37 and 86 (mean of 65,13),
were examined between 1st January 2015 and 31st December 2016.
The CT examinations were performed using a 64-row multidetector machine and the MRI exams with a 1.5 T device,
both from the same manufacturer.
Head non-enhanced and contrast-enhanced protocols were used.
Standard MRI sequences included sagittal T1,
axial T2,
Flair,
diffusion-weighted imaging (DWI),
Apparent Diffusion Coeficient (ADC) and 3D fat-saturated T1 post-Gadolinium injection.
Axial T2*,
coronal or 3D Flair,
small FOV coronal T1 and T2 (for the pituitary gland) and cube sequences (for the internal acoustic canal) were added according to imaging findings.
Some patients were examined during supra-aortic arteries studies (Fig.
3 and 4) and one patient with CT reconstructions for the facial bones (Fig.
9).
