The smaller the voxel, the better the resolution of the images. 3D RECONSTRUCTION Issue #2 to Remember Images can be obtained in 3 planes: Sagittal Coronal Horizontal (axial) IMAGES HAVE A “CLINICAL ORIENTATION” WHERE THE LEFT SIDE OF THE BRAIN IS SEEN IN THE RIGHT SIDE OF THE IMAGE. Issue #3 to Remember LeftRight ACQUISITIONS TO BE REVIEWED • CT scan • MRI • PET...
