Ronald A. Cohen, MD, leads our team of Diagnostic Imaging team at Children’s Hospital & Research Center Oakland. They are specially trained to use the best imaging techniques to diagnose medical and surgical problems in children. The diagnostic imaging process can be anxiety provoking for children and parents, but these subspecialists understand the unique needs of kids and are trained to help them feel more at ease. Dr. Cohen can discuss state-of-the-art imaging techniques such as x-ray, ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, and the range of diagnostic imaging methods used to examine children. He and his team ensure that all examinations are performed properly and safely, using techniques that minimize radiation exposure. Dr. Cohen has given lectures nationally on a variety of topics including pediatric airway imaging and advanced applications of computed tomography.
The Diagnostic Imaging Department at Children’s Hospital Oakland performs more than 65,000 exams each year. We test, evaluate and diagnose results for many pediatric health conditions including cancer, infections, congenital abnormalities and trauma.

Computed tomography (CT), originally known as computed axial tomography (CAT or CT scan) is a medical imaging method. A CT scanner is a specialized x-ray machine that looks like a “large square doughnut,” and uses computerized digital geometry processing to generate two- or three-dimensional images.
Computed Tomography Angiography
Computed tomography angiography (CTA) uses CT images to visualize blood flow in arterial and venous vessels throughout the body, from arteries serving the brain, to those bringing blood to the lungs, kidneys and limbs. CT combines the use of x-rays with computerized analysis of the images. X-rays are passed from a rotating device through the area of interest in the patient's body from several different angles to create cross-sectional images, which are then assembled by a computer into a three-dimensional picture of the area being studied. A CT scanner is a specialized x-ray machine that looks like a “large square doughnut.”
