In which year was transcranial Doppler (TCD) first used?

• A. 1980
• B. 1982
• C. 1990
• D. 1995

Answer: (B)

Transcranial Doppler (TCD) ultrasound was first introduced in the early 1980s, with significant advances occurring in 1982. This innovation allowed for the non-invasive assessment of cerebral blood flow, particularly in detecting abnormalities in blood velocity and flow within the brain's vascular structures. The correct answer reflects the pivotal year when TCD began being utilized clinically, marking a significant step forward in neurovascular monitoring and research. This technology has since become an essential tool in understanding various cerebral conditions and guiding treatment decisions.
