Abstract

Transcranial Doppler (TCD) ultrasound is a crucial non-invasive tool for assessing cerebral blood flow and is widely used to diagnose and monitor cerebrovascular diseases. This paper reaffirms the importance of TCD, details examination methods and precautions, and provides a guide for practitioners. TCD evaluates the blood flow velocity to assess stenosis, occlusion, and hemodynamic changes. Distinguishing between increased blood flow volume and decreased vessel diameter based solely on velocity is challenging, necessitating a comprehensive approach to integrating clinical findings and hemodynamic changes. The reliability of TCD results depends on the skill of the examiner and requires standardized procedures and continuous training. Advances in automation and artificial intelligence promise enhanced accuracy and reliability. Future research should focus on validating and clinically applying these technologies. This paper is a review of the clinical significance of TCD, methods, and precautions, offering a valuable guide for practitioners and highlighting the potential benefits of ongoing advancements in TCD for the diagnosis and treatment of cerebrovascular diseases.

경두개 도플러(transcranial doppler, TCD) 초음파는 뇌혈류를 평가하는 데 중요한 비침습적 도구로, 뇌혈관 질환의 진단과 모니터링에 널리 사용되고 있다. 본 논문은 TCD의 중요성을 재확인하고, 검사 방법 및 주의 사항을 정리하여 실무자에게 가이드를 제공하고자 한다. TCD는 혈류 속도 변화를 평가하여 뇌혈관 협착, 폐색, 혈류 역학적 변화를 평가한다. 그러나 혈류 속도만으로는 혈류량 증가와 혈관 직경 감소를 구분하기 어렵다. 따라서 임상 소견과 혈류 역학적 변화를 통합적으로 고려한 종합적 접근이 필요하다. TCD 결과의 신뢰성은 검사자의 기술에 크게 의존하므로 표준화된 절차와 지속적인 교육 및 훈련이 필요하다. TCD 분석의 자동화와 인공지능(AI) 기술의 발전은 정확성과 신뢰성을 향상시킬 수 있는 잠재력을 가지고 있다. 향후 연구는 이러한 새로운 기술들을 검증하고 임상에 적용하는 데 중점을 두어야 한다. 본 논문은 TCD의 중요성, 검사 방법, 주의사항을 검토하며, 실무자에게 유용한 가이드를 제공하고자 한다. TCD의 지속적인 발전과 임상 적용 확대가 뇌혈관 질환의 진단 및 치료에 기여하기를 기대한다.
