A new dimension in imaging technology detects minute levels of vascular damage in the form of bleeding, clots and reduced levels of oxygenation that may better illuminate our understanding of brain injury, particularly related to trauma. Pictured here is a mild traumatic brain injury case in the presence of both blast and subsequent traumatic brain injury.

Middle image: SWI filtered phase. Right image: SWIM data showing quantified iron content.
