DaTscan for Parkinson’s
Lake Medical Imaging was the first facility in Florida to offer DaTscan: a Nuclear Medicine test that helps physicians determine if a patient may have a Parkinsonian syndrome (PS), such as Parkinson’s Disease (PD).
DaTscan (Ioflupane I-123 injection, also known as phenyltropane) is a radiopharmaceutical agent that is injected into the bloodstream to assess dopamine-containing neurons, which are involved in controlling movement. One of our Nuclear Medicine technologists uses a gamma camera to capture images of your brain. By analyzing the images, the radiologist, in consultation with your physician, helps to determine if the symptoms you or your loved one are experiencing are the result of Parkinsonian syndrome. Parkinsonian syndrome occurs when certain neurons of the brain undergo degeneration. The DaTscan study is primarily designed to differentiate Parkinsonian syndrome from a relatively benign condition called essential tremor (ET).
DaTscan is a radiopharmaceutical that is administered prior to a SPECT (single-photon emission computed tomography) scan to help a radiologist detect if there is degeneration of dopamine transporters in the brain. Studying this degeneration, along with a patient’s changes in functioning, helps physicians to determine if a patient’s symptoms may be related to a Parkinsonian syndrome rather than an essential tremor (ET).
Our subspecialty trained neuroradiologists are experts at diagnosing neurological abnormalities. Patients interested in finding out whether this test could give them the answers they seek should ask their neurologist or primary care provider if a DaTscan is right for them.
