CHRISTUS Santa Rosa Hospital – San Marcos adds new imaging test that can help diagnose Parkinson’s disease and Dementia

January 10, 2023

San Marcos, Texas – CHRISTUS Santa Rosa Hospital – San Marcos is excited to add a new, non-invasive imaging test for patients that can help physicians diagnose Parkinson’s disease and Dementia.

The Dopamine Transporter Scan (DaTscan) involves a procedure where a drug is injected into the bloodstream and is used to assess dopamine containing neurons. These neurons are involved in controlling movement. The radioisotope injection circulates around the body, making its way to the brain. A nuclear medicine camera is then used to capture images of the patient’s brain. A radiologist examines those images and will determine whether Parkinson’s disease or Dementia is detected, looking to see if the radioisotope injection can be seen in the brain.

“This state-of-the art technology now allows us to offer a new innovative and non-invasive approach in determining a life-changing diagnosis for our patients,” said Shayne Musick, director of radiology for CHRISTUS Santa Rosa Hospital – San Marcos. “We are so glad we are now able to offer this for our patients in the San Marcos community.”

This test goes beyond a conventional MRI. In fact, in many cases MRI imaging could appear normal, therefore, not confirming the diagnosis. However, the DaTscan, coupled with a neurologist’s examination, can confirm either a Dementia or Parkinson’s disease diagnosis. The non-invasive procedure can also help physicians in differentiating Parkinson’s disease from essential tremor.

“This scan is just the most recent example of our commitment to continue to bring innovative care to our patients,” said Thomas McKinney, president of CHRISTUS Santa Rosa Hospital – San Marcos. “I am proud of our radiology team for recognizing a need and for looking for opportunities to help us advance our care. Our patients and their families can rest assured they will receive the highest-quality care when they choose CHRISTUS Santa Rosa Hospital ­– San Marcos.”
