Can a CT scan post-head injury aid in diagnosis?

Question

Hello doctor,

My mother, who is 50 years old, sustained a head injury. The doctor recommended a CT or computerized tomography scan. Could you explain why this scan is necessary? Can it provide multiple images of the brain? Will it help diagnose my mother's issue quickly? Are there any side effects associated with it? We are unfamiliar with CT scans; this is her first time undergoing one. Can you provide more information? Please help.

Thank you.

Hello,

Welcome to icliniq.com.

We feel glad that you reached out to us.

A computerized tomography (CT) scan is typically the initial diagnostic procedure conducted in an emergency room for suspected traumatic brain injuries. This imaging technique utilizes a series of X-rays to generate detailed brain images, enabling swift identification of fractures, hemorrhages (internal bleeding episodes within tissues or organs), hematomas (collections of blood outside of blood vessels), contusions (bruises caused by bleeding under the skin), and brain swelling.

It is important to note that CT scans involve exposure to X-ray radiation, which accumulates over time and heightens the risk of cancer. Thus, minimizing unnecessary radiation exposure is advisable.

Recovery from head injuries takes time, during which mild symptoms such as headaches, dizziness, nausea, light or noise sensitivity, and cognitive challenges may persist but typically improve gradually.

However, if you experience worsening headaches, extreme drowsiness (a state of feeling sleepy or lethargic), disorientation (state of confusion), repeated vomiting, abnormal behavior, seizures (sudden and uncontrolled bursts of electrical activity in the brain), unilateral weakness or numbness, or impaired balance or speech, immediate medical attention at the emergency department is crucial.

I hope this helps.
