SPECT (Single-photon emission tomography) imaging is emerging as a necessary tool in the evaluation and treatment of patients with TBI (traumatic brain injury) based on results of a recent study. One of the reasons is the imaging provides greater ability to detect lesions than MRI and CT imaging, which remain valuable diagnostic tools to identify acute damage to the structures of the brain.
The difference with SPECT is that it can show dynamic information and show functional deficits…deficits that standard imaging such as MRI and CT do not reveal. Given the difficulties of obtaining a definitive TBI diagnosis, especially in mild cases, SPECT can offer valuable information in conjunction with neuropsychological testing.
