Introduction
In general, whether a CT scan or transcranial Doppler ultrasound (TCD) is better for evaluating headache depends on the individual's specific condition. Different symptoms may require different diagnostic approaches, so one method may be more suitable than the other. If a patient experiences severe headache, it is advisable to seek medical attention promptly, identify the exact cause, and receive appropriate treatment to avoid delaying diagnosis and management.
In general, whether a CT scan or transcranial Doppler ultrasound (TCD) is better for headache evaluation depends on the individual's specific condition. Different symptoms require different diagnostic approaches, so one method may be more suitable than the other in certain cases. Details are as follows:
1. CT is better
CT imaging uses X-rays, which can penetrate the skull to visualize soft tissues inside the cranium. It helps diagnose skull fractures, intracranial fluid accumulation, cerebral hemorrhage, cerebral infarction, and space-occupying brain lesions. If headaches are suspected to result from a skull fracture, a CT scan is recommended.
2. Transcranial Doppler ultrasound (TCD) is better
TCD uses sound waves to create images. Since ultrasound waves cannot easily penetrate dense bone structures like the skull, they pass through cranial sutures to evaluate intracranial blood vessels. This technique assesses blood flow velocity, direction, and vessel wall elasticity, providing valuable information for diagnosing cerebral vascular stenosis or occlusion. If a patient has known or suspected cerebrovascular disease, TCD is recommended.
If headaches are severe, patients should seek timely medical attention to determine the exact cause and receive appropriate treatment, avoiding delays that could worsen the condition.
