A colour doppler scan is an imaging test done on an ultrasound machine to check the direction and speed of blood moving through blood vessels (arteries and veins). It is a non-invasive test done using a special high frequency transducer, moved on the surface of the body following the course of blood vessels. Based on the flow velocity and direction, arbitrary colour coding is done. It is used commonly to study arteries in both arms and legs in order to identify clots or narrowed arteries. A potentially life-threatening condition called the deep vein thrombosis (DVT) is detected using colour doppler. Varicosities of legs is a condition which frequently requires doppler evaluation to visualize the extent and severity of the problem. Not only the limbs, colour doppler is also routinely done to evaluate neck and renal vessels which provide blood supply to critical parts of body such as brain and kidneys respectively. In males, a scrotal doppler, is performed to identify blood supply inside scrotum. This study can identify cases of testicular torsion and few other conditions such as varicocele and epididymo-orchitis.  Similarly in females, a pelvic doppler is often required in cases of ovarian torsion. In addition, colour doppler is used during pregnancy to evaluate blood circulation in the baby, uterus and placenta. 

At MITR Hospital Kharghar, all types of Doppler studies are done.
