What type of imaging study is indicated for a patient with suspected brain hemorrhage?

A non-contrast CT scan of the head is the preferred imaging study for a patient with a suspected brain hemorrhage. This type of scan is particularly effective because it quickly provides detailed images of the brain structure and can rapidly identify the presence of bleeding.

In the context of an acute neurological event, time is critical, and non-contrast CT is readily available in emergency settings, allowing for swift assessment of hemorrhagic conditions. The scan can differentiate between various types of brain injuries, including subarachnoid hemorrhage, intraparenchymal hemorrhage, and subdural hematomas, based on the density of blood compared to the surrounding brain tissue.

Other imaging modalities, such as MRI of the brain, are not typically used in the emergency setting for suspected brain hemorrhage due to their longer acquisition time and less immediate availability. While MRI provides excellent soft-tissue contrast and can detect smaller or more subtle lesions, in an emergency context, the urgency in ruling out hemorrhage takes precedence. Therefore, it is not the first-line investigation in such scenarios.

Contrast CT scans are generally avoided when there is a suspicion of hemorrhage because the contrast agent can obscure the bleeding and lead to misinterpretation of the findings. This approach is more suited
