Introduction
In general, a head injury with bleeding can be detected by CT scan. CT is a common imaging method that uses X-rays to scan the patient's body structures and can effectively identify any abnormalities. Brain hemorrhage appears as a white, high-density lesion on a brain CT scan, which is relatively easy to recognize.

Under normal circumstances, a head CT scan can detect bleeding after a head injury. Here's a detailed explanation:

CT scan is a common imaging examination that primarily uses X-rays to scan the body's structures and identify any abnormalities. In cases of brain hemorrhage, a white, high-density lesion appears on the brain CT image, which is relatively easy to recognize. However, it should be noted that CT scans may occasionally miss diagnoses—particularly in cases of very small or microscopic bleeding, which might not be easily detected. Therefore, when necessary, further diagnostic methods such as MRI or lumbar puncture may be recommended to assist in diagnosis.

It is advised that patients seek medical attention promptly if they experience any symptoms, and follow standardized treatment under a doctor’s guidance to promote recovery.
