Peter Coulson, M.D.

Peter Coulson is originally from Nolensville, Tennessee just outside Nashville. He attended medical school at the University of Tennessee in Memphis, then moved to the Knoxville campus for his final two years. He remained in Knoxville for his internship and general diagnostic radiology residency before moving to Charlottesville for his neuroradiology fellowship at the University of Virginia.

Dr. Coulson is the first in his family to attend medical school. He admits that he hadn’t seriously considered medicine as a career until he took a college course in digital image processing which focused on math, science and converting the signal obtained by a CT or MRI to a clinical image for interpretation. “That was my first exposure to the field of radiology and immediately thought wow, now THAT’s something I could see myself doing for the rest of my life,” Dr. Coulson shared. His clinical rotations during medical school confirmed that radiology was the right path he wanted to pursue. 

Neuroradiology, in particular, was attractive to Dr. Coulson because of his interest in the brain and nervous system. “Neuroradiology is applicable in a wide range of clinical situations from routine outpatient imaging to an acute stroke case,” he explained. He enjoys the technology advancements in neuroimaging techniques in recent years. One that’s been particularly useful is the addition of brain CT perfusion imaging in cases of suspected stroke. The perfusion data is often helpful in cementing or further characterizing the diagnosis. “While artificial intelligence hasn’t made much of an impact in our day to day treatment yet, I’m confident that machine learning and CAD techniques will someday play a larger role,” Dr. Coulson shared.

After living in Knoxville during medical school and residency, choosing to stay in the area and join the Vista Radiology group was an easy decision. In his spare time, Dr. Coulson enjoys running, hiking, playing tennis and traveling to central Europe.

H. Robert Hixson, MD

Robert Hixson always knew he wanted a profession that allowed him to help others.  When he was 12 years old, he decided to redirect his attention from becoming a veterinarian to a medical physician so that he could care for people.  Originally from Chattanooga, Tennessee, Robert attended a small liberal arts college before moving to Memphis, Tennessee for medical school. During college, he enjoyed all of his radiology rotations, but his love for the intensive training of the brain ultimately peaked his interest.  He completed his internship in Newport News, Virginia before moving to Charlottesville, Virginia for his residency, fellowship and an additional two years of neuro interventional as well as diagnostic training. The combination of neuro and diagnostic specialties fit him like a glove.  “I love being a detective in diagnosing a problem,” explained Dr. Hixson. He continued, “Influencing and being hands-on in patient care is what makes my job so fulfilling.”

Dr. Hixson joined Vista Radiology in 2017. He was impressed with how well established the group’s neuro interventional program was and wanted to be part of the high level care.  “I enjoy working in a program with some of the most innovative technology advancements.”  Nestled near the Great Smoky Mountains National Park, Vista Radiology was the perfect fit for a self-professed lover of the outdoors.  It also allowed he and his wife to live near their family.

In his spare time, Dr. Hixson enjoys playing with his son and spending time mountain biking with his wife.  He is an avid mountain climber having topped the likes of Mount Rainier in Washington, Mont Blanc in Italy as well as mountains in Ecuador. His love for outdoor adventures led him to pursue an Advanced Wilderness Life Support Certification which included training in alpine, swift water rapid, and dessert medicine.

Innovative Lung Clot Treatment

Innovative Technique in Lung Clot Removal

Recently, I spoke with Jeffrey M. Roesch, M.D., a vascular and interventional radiologist with Vista Radiology, about an innovative technique he and his team are using to treat lung clots.

Many patients, who suffer from submassive and massive pulmonary emboli, or lung clots, experience a shortness of breath or unstable heart performance. If large enough, they can be fatal. In some cases, the patient is treated, in the emergency room, with a strong blood thinner which enables improved flow. However, in situations where patients have cancer, ulcers, or other risks of bleeding, medication is not the safest option. That’s where the INARI device comes into play.

Using a pencil size “flow retriever” Dr. Roesch is able to remove the lung clots while the patient is still awake resulting in almost immediate results.  “They get better right away resulting in increased oxygen and respiratory levels as well as a stabilized heart rate,” explained Dr. Roesch.  “There’s also a cost benefit to hospitals having this device available. Most patients are able to return home the following day which reduces the likelihood of infections and improves their overall outcome. We’re also able to avoid the risk of bleeding related to blood thinners,” he continued.

The device is currently in trials with several Vista Radiology partnering locations. More improvements in its design, are expected in early 2021.
