<br/><br/> ABSTRACT:<br/>Background: Cerebral infarction is a significant contributor to global morbidity and mortality rates, serving as the foremost cause of both disability and mortality worldwide. Imaging in the acute setting of suspected stroke is a crucial consideration for emergency physicians and radiologists. The purpose of stroke imaging is to precisely identify the lesion in a timely manner, with the aim of facilitating appropriate management. The utilization of monitor displays for the purpose of analyzing medical images is a crucial component of contemporary radiology work environments.<br/>Methods This was a cross-sectional validation study conducted at the radiology section of FEU-NRMF Medical Center from June 2023 to October 2023. Thirty radiologists from FEU-NRMF Medical Center who are presently practicing teleradiology were included. They were given 50 random cases of definite positive and definite negative cases, which were all interpreted using the standard medical grade monitor. These cases were assigned with alphanumeric codes and did not have patient identifiers to ensure the privacy and confidentiality of data. The participants were blinded on the findings based from the standard medical grade monitor. These 50 cases randomly assigned for each Radiologist were assessed using Twisted Nematic and In-plane switching monitor panels which were provided by the primary investigator.<br/>Results In the 1500 (50 scans x 30 radiologists) cases included for CT scan interpretation, the use of twisted nematic monitor panels correctly identified 68% patients with acute brain infarction and hemorrhage while 80% with no diseases were correctly identified. The observed sensitivity was 68%, specificity was 80%, positive predictive value was 77%, and negative predictive value was 71%. The overall accuracy was 74%. The use of in-plane switching monitor panels correctly identified 76% patients with acute brain infarction and hemorrhage while 84% with no diseases were correctly identified. The observed sensitivity was 76%,<br/>specify was 84%, positive predictive value was 78%, and negative predictive value was 78%. The overall accuracy was 80%.<br/>Conclusions Both the use of twisted nematic and in-plane switching monitor planes demonstrated acceptable accuracy for detecting acute brain infarction and hemorrhage in CT scan images for teleradiology. However, in-plane switching monitor planes showed marginally higher diagnostic performance. Future randomized studies the will involve larger number of radiologist participants are recommended to validate further the results of this study.<br/>
