For optimal superficial resolution, which US probe frequency should be used?

Using a frequency of 10 MHz or greater is optimal for achieving superficial resolution in ultrasound imaging. Higher frequency probes provide improved detail and resolution because they produce shorter wavelengths, which are better at capturing fine structural details near the skin's surface. This is particularly important in phlebology, where understanding the intricacies of veins and surrounding tissues can significantly aid in diagnosing conditions such as varicose veins and venous insufficiency.

In this context, lower frequency probes, such as 5 MHz, 2 MHz, or 1 MHz, result in increased penetration depth but compromise resolution. These lower frequencies are more suited for imaging deeper structures, where fine detail is less critical. Therefore, for evaluating superficial tissues and performing assessments related to vascular structures close to the skin, utilizing a probe frequency at 10 MHz or higher is essential to achieve the clarity and detail necessary for accurate diagnosis and evaluation.
