Correct Answer � B Explanation |

Ans: B.) Duplex imaging.
Varicose veins are shown in the image.
VARICOSE VEINS
Investigations:
- Doppler examination – only when duplex is not available
- Tourniquet tests and the use of hand-held Doppler have now largely been abandoned.
- USG abdomen, peripheral smear, platelet count, other relevant investigations are done depending on the cause of the varicose veins
- Photoplethysmography: Using probe transmission of light through the skin, venous filling of the surface venules which reflects the superficial venous pressure is measured.
- Duplex scan: It is a highly reliable U/S Doppler imaging technique (here high-resolution B mode ultrasound imaging and Doppler ultrasound are used) which along with direct visualization of veins, gives the functional and anatomical information, and also color map. Duplex Ultrasound imaging – the gold standard.
