Hemorrhagic brain contusions are some of the most common sequelae of traumatic brain injury. Prompt detection of these intraparenchymal hemorrhages can alter the management and monitoring regimen for these patients. These injuries are most common in the inferior frontal regions and anterior temporal poles, which can be blind spots for inexperienced or non-specialized radiologists. The algorithm would identify and characterize the presence of hemorrhagic brain contusion that can then aid in case prioritization.
A 25-year-old male presents to the emergency room after a motor vehicle accident complaining of a severe headache. The patient is confused and dizzy; the emergency department orders a non-contrast head CT scan to assess for intracranial hemorrhage.
DICOM images from the non-contrast head CT are exported to the AI engine. The images are analyzed and an alert/screenshot are sent to PACS with the classification information. The information generated is integrated with PACS and the radiology information system (RIS) prioritizes the examination on the worklist and automatically populates the report on the dictation software with ability for manual editing when launched/selected by the radiologist for interpretation.

History |
History of head trauma (motor vehicle collision, fall with head injury, penetrating trauma) |

Identification of hemorrhagic contusion |
High attenuation cortical/subcortical lesion with surrounding lucency and mass effect in a non vascular configuration. |
|
Confounders |
The most common locations of involvement are the inferior frontal lobes and anterior temporal poles that are also common areas of beam hardening artifacts on head CT scans. Another confounder is partial volume averaging that can obscure a small contusion at the base of the skull. |
