The purpose of this study was to detect cerebral microhemorrhages in military service members with chronic traumatic brain injury by using susceptibility-weighted magnetic resonance (MR) imaging. The longitudinal evolution of microhemorrhages was monitored in a subset of patients by using quantitative susceptibility mapping.

Traumatic Brain Injury Use Case
The STAGE protocol is designed to be highly sensitive to the visualization of lesions that may originate from trauma. STAGE has the ability to demonstrate key vascular brain damage which may be missed by conventional or low resolution scans…
Hearing impairment after subarachnoid hemorrhage
Subarachnoid hemorrhage (SAH) survivors experience significant neurological disability, some of which is under‐recognized by neurovascular clinical teams. We set out to objectively determine the occurrence of hearing impairment after SAH, characterize its peripheral and/or central origin, and investigate likely pathological correlates.
Assessment of Brain Venous Structure in Military Traumatic Brain Injury Patients using Susceptibility Weighted Imaging and Quantitative Susceptibility Mapping
Brain venous volume above the lateral ventricle in military patients with traumatic brain injury (TBI) was assessed using two segmentation approaches on susceptibility weighted images (SWI) and quantitative susceptibility maps (QSM).
Quantitative MR image processing opens up new avenues of treatment for Traumatic Brain Injury (TBI) in Veterans
For many, the term Traumatic Brain Injury (TBI) brings to mind the 2015 film “Concussion”, starring Will Smith and based on the true story of Dr. Bennett Omalu, who discovered the link between repeated trauma to the head endured by professional football players and brain function degradation.
FDA gives go-ahead for SpinTech’s SPIN-SWI software
Original Article by John R. Fischer , Staff Reporter, DOTmed SpinTech, Inc., an MR software producer, has received the go-ahead from the FDA to begin sales for its SPIN-SWI software solution. The Michigan-based enterprise has devised what it says is the first in a...
The Need for Enhanced Imaging Software for TBI
Current imaging technologies are unable to accurately identify the key-biomarkers for traumatic brain injury in a clinically meaningful timeframe. The result can be deadly. Read more from the Wall Street Journal: ...
Susceptibility Weighted Imaging: Current Status and Future Directions
Abstract Susceptibility weighted imaging (SWI) is a method that uses the intrinsic nature of local magnetic fields to enhance image contrast in order to improve the visibility of various susceptibility sources and to facilitate the diagnostic interpretation. It is...
MR imaging findings in mild traumatic brain injury with persistent neurological impairment
Magnetic resonance imaging provides objective biomarkers in the diagnosis of brain injury by detecting brain lesions resulting from trauma. This paper reports on the detection rates of presumed trauma-related pathology using fluid-attenuated inversion recovery (FLAIR) and susceptibility-weighted imaging (SWI) in TBI patients with chronic, persistent symptoms.
Cerebral Hemodynamic Changes of Mild Traumatic Brain Injury at the Acute Stage
Mild traumatic brain injury (mTBI) is a significant public health care burden in the United States. However, we lack a detailed understanding of the pathophysiology following mTBI and its relation to symptoms and recovery. With advanced magnetic resonance imaging (MRI), we can investigate brain perfusion and oxygenation in regions known to be implicated in symptoms, including cortical gray matter and subcortical structures.
Detection of hemorrhagic and axonal pathology in mild traumatic brain injury using advanced MRI: Implications for neurorehabilitation
There is a need to more accurately diagnose milder traumatic brain injuries with increasing awareness of the high prevalence in both military and civilian populations. The overarching hypothesis of this paper is that newer, advanced MR imaging generates sensitive biomarkers of regional brain injury which allows for correlation with clinical signs and symptoms.
