Table 1. Evaluation of the reliability of the landmarks.
We report the estimated percentiles of distances in millimeters between first and second marking for each proposed landmarks. P 75: 75th percentile of distances in millimeters. P 80: 80th percentile of distances in millimeters. P 95: 95th percentile of distances in millimeters. Our reliability score is defined in section 5.1. LALV: Anterior Horn of the Left Lateral Ventricle, RALV: Anterior Horn of the Right Lateral Ventricle, PTP: Posterior Tectum Plate, LCB: Left Cerebellar Brainstem Junction, RCB: Right Cerebellar Brainstem Junction, LFOM: Left Deep Grey Border at Foramen of Monro, RFOM: Right Deep Grey Border at Foramen of Monro, LACSP: Left Deep Grey Border at Anterior Cavum Septi Pellucidi line, RACSP: Right Deep Grey Border at Anterior Cavum Septi Pellucidi line, LPCSP: Left Deep Grey Border at Posterior Cavum Septi Pellucidi line, RPCSP: Right Deep Grey Border at the Posterior Cavum Septi Pellucidi line.
