Inland Imaging has expanded its noninvasive vascular lab equipment toinclude a new Transcranial Doppler (TCD) system which is used to investigate the intracranial arteries through Doppler ultrasound technology. The test has the ability to measure blood flow velocity and direction in the blood vessels of the brain to aid in the diagnosis of emboli, stenosis, and vasospasm.
The TCD study, introduced in the late 1980’s, has grown steadily in popularity in the United States as a test to successfully monitor the risk of stroke and vascular disease. The painless technique determines the speed and direction of blood flow. The TCD exam is similar to any other ultrasound type study in that a hand held transducer is passed lightly over the skull above an artery.
Blood flow velocity is recorded by emitting high-pitched sound waves that bounce off the structures of the area being studied. The skull can block the transmission of ultrasound waves, so "windows" in the skull such as the temporal region, through the eyes, below the jaw, or back of the head must be used to obtain the information.
Inland Imaging is fortunate to have vascular technologists experienced in TCD and it’s applications. TCD is often used in conjunction with other tests such as MRI, MRA, carotid duplex ultrasound, and CT scans.
The added TCD service is available at the Inland Imaging Holy Family Hospital center. Questions regarding the new exam can be directed to Inland Imaging Vascular Services Manager, Monte Madsen at 509-953-2540.
