Color Doppler ultrasound is primarily used to evaluate the direction and speed of blood flow within vessels. This technique utilizes the Doppler effect to visualize blood flow in real-time, helping to assess vascular conditions, such as blockages or abnormalities in blood circulation. The color coding in the Doppler imaging indicates the flow of blood towards or away from the transducer, providing crucial information that aids in diagnosing cardiovascular issues or other related conditions.

The other options do not accurately represent the primary function of color Doppler ultrasound. While organ size and wall thickness can be evaluated with ultrasound techniques, they are not specific functions of color Doppler. Similarly, assessing solid tumors typically involves different imaging modalities and evaluations, making the correct answer distinctly focused on the specific abilities of color Doppler technology.
