Is a Doppler ultrasound painful || Shri Ram Medical College.

Doppler ultrasonography is a noninvasive diagnostic that estimates blood flow by reflecting high-frequency sound waves (ultrasound) off of circulating red blood cells. Ordinary ultrasounds employ sound waves to create images, but they cannot display blood flow. Doppler ultrasounds measure blood flow by pitch shift (frequency). During a Doppler ultrasonography, a sonographer rubs a small portable instrument (transducer) against your skin as needed. The Doppler ultrasound test is used to monitor blood flow. If a pulse is detected, that means blood is flowing to that leg. Diseases like peripheral artery disease (PAD) and diabetic foot ulcers can be identified and treated with its aid. Handheld Doppler tests are more helpful than finger-based pulse checks because of their accuracy and portability. Doppler ultrasound with colour imaging. This Doppler technique employs the usage of a computer to convert sound waves into visible light. These hues represent the rate and course of actual blood flow. Ne
