An associate of Dr. Charles
Dotter at the University of Oregon in Portland, radiologist Dr. Melvin
Judkins studied coronary angiography with Dr. Mason Sones. Judkins
went on to create his own system of diagnostic imaging, introducing
a series of specialized catheters and perfecting the transfemoral
approach (introducing the catheter via a groin puncture rather than
the more complex procedure used by Sones of introducing the catheter
via surgical opening of the brachial artery in the arm).
 
A careful perfectionist, Judkins went to great lengths to educate
his patients, train his colleagues and share his techniques, and continued
his work at Loma Linda Medical Center. Judkins furthered the goal
of an accessible, systematic approach to high quality diagnostic radiology.
The Judkins Technique of coronary angiography remains the primary
diagnostic tool used in catheterization laboratories around the world.
