Vasospasm Digital

Your doctor has requested photoplethysmography to determine if there is a problem with your circulation to your fingers or toes under certain conditions. The circulation to your fingers and toes will be measured before and after submersion in cold water.

At the Cedars-Sinai S. Mark Taper Foundation Imaging Center, we have a specialized team of physicians and technologists who are experts in ultrasound technology.

You will be lying on the exam table on your back with your hands at your sides. The technologist will apply a warm gel to your arms and a transducer or a small microphone will be used to examine your arteries.

You will hear the sound of moving blood during the exam. Do not be alarmed; it is harmless. The exam will take approximately 60 minutes.
