Applications of magnetic resonance imaging in the diagnosis of posttraumatic stress disorder.

The application of magnetic resonance imaging (MRI) techniques in diagnosing posttraumatic stress disorder (PTSD) represents a significant research focus, providing deeper insights into trauma-related psychological disorders. PTSD often arises from chronic stress, a state in which the body struggles to adapt to overwhelming stimuli. Patients frequently experience persistent flashbacks (intrusive memories or sensory recollections of the traumatic event) and nightmares, which evoke intense emotional responses and disrupt daily life. These recurring episodes of stress and anxiety severely impact behavior and functioning. Understanding the brain changes associated with PTSD has become possible through advancements in MRI studies. This article aims to review the scientific literature on the use of magnetic resonance imaging techniques in diagnosing posttraumatic stress disorder. The review is based on scientific literature from medical databases, including Web of Science and Scopus, covering publications up to October 30, 2024. The findings from this analysis may contribute to a better understanding of the neurobiological mechanisms underlying PTSD.
