MTA score: 0: no CSF is visible around the hippocampus (normal); 1: choroid fissure is slightly widened; 2: moderate widening of the choroid fissure, mild enlargement of the temporal horn and mild loss of hippocampal height; 3: marked widening of the choroid fissure, moderate enlargement of the temporal horn, and moderate loss of hippocampal hei. The MTA score, published by Scheltens and colleagues in 1992 [ 4 ], is a simple measure by which mesiotemporal atrophy can be quantified. Using the width of the choroidal fissure, temporal horn, and height of the hippocampal formation, atrophy is evaluated in five grades (0-4). Results. Patients with AD had higher MTA scores (mean, 2.13) and ERICA scores (mean, 2.05) than patients with SCD (P < .001).An ERICA score of 2 or greater achieved a higher diagnostic accuracy (91%) than the MTA score (74%), with a sensitivity of 83% versus 57% and a specificity of 98% versus 92% in discriminating dementia caused by AD from SCD (P < .001).

Scores of MTA correlated to age and Mini-mental state examination score. When used to detect DAT from NC, the MTA showed highest diagnostic value than other scales, and when the cutoff score of 1.5 of MTA scale, it obtained an optimal sensitivity (84.5%) and specificity (79.1%) respectively, with a 15.5% of false negative rate. MTA correlation with quantitative volumetric methods ranged from -0.20 (p< 0.05) to -0.68 (p < 0.001) depending on the quantitative method used. Both MTA and FreeSurfer are able to distinguish dementia subgroups from CH. Suggested age-dependent MTA thresholds are 1 for the age group below 75 years and 1.5 for the age group 75 years and older. Visual rating of medial temporal lobe atrophy (MTA) is often performed in conjunction with dementia workup. Most prior studies involved patients with known or probable Alzheimer's disease (AD). This study investigated the validity and reliability of MTA in a memory clinic population. MTA was rated in 752 MRI examinations, of which 105 were performed in cognitively healthy participants (CH. Usage An ERICA score of 2 or 3 (see below) has been shown to have higher diagnostic accuracy for distinguishing healthy controls with subjective cognitive decline from individuals with Alzheimer disease than the older medial temporal lobe atrophy (MTA) score 1 . diagnostic accuracy = 91% sensitivity = 83% specificity = 98% Imaging

Objective To evaluate the diagnostic performance and reliability of the medial temporal lobe atrophy (MTA) scale in patients with Alzheimer's disease. Methods A systematic literature search of MEDLINE and EMBASE databases was performed to select studies that evaluated the diagnostic performance or reliability of MTA scale, published up to January 21, 2021. Pooled estimates of sensitivity and. Objective The aim of the study is to visually rate major forms of dementia using global cortical atrophy (GCA), medial temporal lobe atrophy (MTA), and Fazeka's scales and Koedam's score using magnetic resonance imaging (MRI). The purpose is to correlate the visual rating scales (VRS) with severity of dementia. Materials and Methods Thirty patients fulfilling DSM 5 (Diagnostic and.
A general problem with the MTA score is the inconsist-ently dened cuto value. Various cutos for pathological MTA scores can be found in the literature, diering by age groups and education level. For example, Velickaite and colleagues [8] elaborated that "at age 75, gender and edu-cation are confounders for MTA grading. A score of ≥ 2 is Abstract. Background: Medial temporal lobe atrophy (MTA) is a sensitive radiologic marker for Alzheimer disease (AD) and associated with cognitive impairment. The value of MTA in the oldest old (>85 years old) is largely unknown.

The Radiology Assistant : Epilepsy - Role of MRI Epilepsy - Role of MRI Laurens De Cocker, Felice D'Arco and Philippe Demaerel and Robin Smithuis Publicationdate 2012-09-01 In many patients with epilepsy antiepileptic drug treatment is unable to control the seizures. To assess inter-modality agreement and accuracy for medial temporal lobe atrophy (MTA) ratings across radiologists with varying clinical experience in a non-demented population. Methods Four raters (two junior radiologists and two senior neuroradiologists) rated MTA on CT and MRI scans using Scheltens' MTA scale.
