Magnetic resonance imaging (MRI) (at the top), ^{99 m}Tc-MIBI SPECT (in the middle) and fused image of ^{99 m}Tc-MIBI single-photon emission computerized tomography (SPECT)and MRI (at the bottom) in transaxial, coronal and sagittal sections of a metastasis in the left cerebellum deriving from non-small-cell lung cancer(NSCLC, same patient of Figure 1). The left cerebellar metastasis appears as an area of hyperfixation of ^{99 m}Tc-MIBI in the context of normal cerebellar parenchyma without radiopharmaceutical distribution. MRI shows the morphological alteration and the precise anatomical site of the metastasis. Fusion imaging SPECT/MRI allows to anatomically locate the position of the metastasis by MRI, evidenced as an area of selective radiopharmaceutical uptake by ^{99 m}Tc-MIBI SPECT images.
