Transcranial Doppler(TCD) is an important diagnostic tool for evaluating the patients with stroke. It has some advantages and unique role when compared with other neuroimaging modalities. Recent development of transcranial color-coded Doppler(TCD) improves the limitation and pitfalls of TCD. The current indications of TCD are as follows: 1. Screening and evaluation of the intracranial major vessels 2. early detection and follow-up of vasospasm due to SAH 3. emboli detection (high-imtensity transient signals, HITs) 4. dignosis and follow-up of subclavian steal 5. evaluation of intracranial collaterals when the extracranial ICA has severe stenosis or occlusion 6. evaluation of cerebral perfusion pressure (intracranial pressure) 7. evaluation of arteriovenous malformation 8. diagnosis and follow-up of arterial dissenction 9. diagnosis and follow-up of venous sinus thrombosis (experimental).

In this case analysis, a patient was diagnosed with subarachnoid hemorrhage (SAH) in a 49-year-old female and showed persistent vasospasm after coil emboilzation in an aneurysm. The patient suffered from persistent vasospasm and performed angioplasty a total of 6 times. Transcranial color coded doppler (TCCD) was performed 12 times to monitor vasospasm. As a result, repetitive cerebral blood flow tests were low cost and safely performed without exposure to invasive radiation through the TCCD, and the repeatability and reproducibility of the test were confirmed with the capabilities of a trained professional radiological technologist.
