Meet Our Doctors – Dr. Garth McPherson

Prime Imaging


Dr. Garth McPherson decided to become a doctor when he was just 5 years old. “My parents were doctors, and I loved hearing stories about their patients,” he explains. “I’ve been practicing for 31 years now and still love what I do.” As a radiologist, Dr. McPherson spends a lot of time reading CT scans, mammograms, ultrasounds, PET scans, MRIs, and X-rays, but it’s the interactions he has with his patients that motivate him to keep going. He shares, “The nice notes and thankful patients make my day. Chattanooga has a great community – the people and the medical community. My wife and I have raised our nine children here, and I’m glad to be part of the team of medical professionals who serve our area.”

I care for my patients like my own family.”

My Specialties


Dr. Garth McPherson PrimeImaging

1. What do you love most about your profession?

Helping people. With radiology, we can see what is actually happening inside the body. Many patients come to us, convinced of the worst, and I often get to allay their fears.

2. What is your best advice for patients?

Though it’s fine to research your symptoms with Google, don’t trust it over your doctor.

3. What do you see as the most exciting new development for your profession?

All the tailored therapies for cancer are much less toxic and much more effective. We are seeing outstanding cure rates, and I get to follow up with these patients over the years.

4. How does your staff enhance your practice?

Our staff members are the eyes and ears of our practice. Their warm smiles, encouraging words, and gentle interactions with patients make the difference. I am honored to work with a talented team.

5. Why have you chosen this field of specialty?

When I came through medical school, technology in radiology was accelerating with the advent of CT scans. I wanted to be part of this new technology. During my residency, MRI came out, and computers were becoming more powerful. When PET scans became possible, our group was the first to bring a PET scanner to Chattanooga. I have lived through a revolution in radiology technology.
