T2-STIR coronal sections demonstrating HIA ratings of a selection of hippocampi. Top. A randomly selected patient with clear left HS (on right of image). HS is characterised by hippocampal atrophy and loss of HIA. HIA scores on this section were 2 and 4 for the left and right hippocampi, respectively. The magnified box shows the approximate locations of CA1 (1), CA2 (2), CA3 (3), CA4 (4), dentate gyrus (dg) and subiculum (s). Bottom. Left (L) and right (R) hippocampal sections that were graded as I, II, III and IV according to the criteria defined by ver Hoef [10], [11]. All hippocampi are presented in radiological orientation (left = right). All hippocampi presented are from different patients.
