Application of Magnetic Resonance Imaging in the Diagnosis of Post Traumatic Stress Disorder in Stroke
Objective:To explore the diagnostic application of magnetic resonance imaging(MRI)T2 weighted imaging(T2WI)in the diagnosis of post traumatic stress disorder in stroke based on the imaging of the hippocampus and amygdala.Methods:A total of 66 stroke patients admitted from January 2021 to January 2023 were selected as the study subjects,and their clinical data,scale scores,and MRI image information were statistically analyzed.Combining the T2WI image features of the largest layers of the hippocampus and amygdala,extracting corresponding texture feature parameters,applying LASSO regression to dimensionality reduction,and constructing an imageomic model of the hippocampus and amygdala for diagnosing PTSD and non PTSD after stroke.Results:There was no significant difference in demographic and clinical characteristics between PTSD and non PTSD patients after stroke(P>0.05);The scores of PTSD patients after stroke on the modified age related white matter change scale and the civilian version of the PTSD symptom list were higher than those of non PTSD patients(P<0.05).Using LASSO regression,9 hippocampal and 14 amygdala texture feature parameters were effectively screened,and imaging models for diagnosing post stroke PTSD and non PTSD were constructed.Conclusion:T2WI imaging models of the hippocampus and amygdala are highly effective in the diagnosis of PTSD after stroke.The clinical application of magnetic resonance imaging can enhance the diagnosis and evaluation of PTSD after stroke.
