Specialties

Dr. John Johnston has the following 3 specialties

  • Diagnostic Radiology

    Radiologists help doctors get a closer look at what’s happening inside your body. If your primary care doctor wants to investigate your symptoms further, they may refer you to a radiologist to get an ultrasound or x-ray. Some radiologists specialize in mammography and breast imaging, which is who you see when you need a mammogram. A Radiologist can also determine if bones are broken or fractured after any kind of accident.
    Radiologists are trained to perform MRIs and CT scans, both of which are used to determine the presence of diseases or disorders and help your doctor properly diagnose you. They can detect anything from tumors, bleeding and infections to bone and muscle disorders.

  • Radiology

    A radiologist is a physician who specializes in the use of medical imaging to diagnose and treat illnesses or injuries in patients.
    The different types of medical imaging are X-ray, computed tomography (CT) scans, magnetic resonance imaging (MRI), ultrasound, and nuclear medicine.
    Radiologists are experts in these different types of tests and can advise a primary care doctor on which test is most appropriate in a specific case. These doctors also assist primary care doctors in analyzing the images produced by these tests in order to determine next steps necessary for treatment.

  • Vascular and Interventional Radiology

    Interventional radiologists, also known as vascular radiologists, use minimally-invasive imaging techniques to diagnose conditions in your organs and blood vessels. For example, if you need an angiography (an x-ray of the arteries) to diagnose a blockage in your blood vessels, your doctor will refer you to an interventional radiologist. They can, if needed, perform an angioplasty to open up the blocked passage.
    They’re also trained to perform needle biopsies, insert stents, treat varicose veins and obstructions of the urinary tract (possibly due to kidney stones) and can help with dangerous postpartum bleeding. They treat various types of fibroids and embolization, which is a clot, air bubble or other blockage in the bloodstream. While the types of imaging procedures they perform are more invasive than x-rays done to identify broken bones, pain levels and recovery time are usually minimal.
