Post-Concussive Syndrome Index

See It. Believe It. Treat It.

Using a neurological MRI study, we can provide physicians with objective information about the probability of post-concussive brain abnormalities shown on a brain scan.

Qmetrics’ PCS Index provides an objective assessment of brain structural abnormalities, or microtrauma, in mTBI patients. This effectively enables doctors to “see” post-concussive injury in addition to assessing the patient’s symptoms and dysfunction. 

Qmetrics developed the PCS Index to provide everyday patients with access to sophisticated image-based analysis techniques which historically are only accessible to academic researchers, and too laborious to be practical for clinical use.  Leveraging the infrastructure Qmetrics developed to serve worldwide clinical imaging studies, we can provide PCS Index results to clinicians via our secure online image data portal and our imaging core lab.  

Qmetrics used a type of artificial intelligence called machine learning to sift through the massive amount of data and reveal a subset of measurements that best identified the injured patients from the ones with no injury. These measurements comprise the PCS Index and are based on both structural gray and white matter features as well as diffusion metrics.

The PCS Index can provide confirmation to patients that their symptoms are real and likely related to brain injury. Understanding the extent of brain microtrauma may also support therapeutic decisions or add confidence to recovery milestones. 

Qmetrics used radiomics, or mathematical algorithms measuring three-dimensional signal patterns and textures in the MRI data and AI to discover the radiomic features present in post-concussive patients, but not in patients without diagnosed brain injuries, to build a formula to identify post-concussive microtrauma. This is the PCS Index, a number between zero and one derived from multiple 3D features of a single MRI exam that provides an objective indicator of post-concussive microtrauma severity. The higher the number, the more severe the post-concussive injury.

Qmetrics is expert at extracting meaningful information from medical images using algorithms to precisely detect and measure physiology that may be impossible to see via observation. These three-dimensional patterns, textures and data signals are often a combination of factors from different imaging series and clinical data that together provide the answer to your questions.
