Definition : PI-RADS: The central zone is the region of the prostate surrounding the ejaculatory
ducts posterior and superior, from the base of the prostate to the verumontanum. Its
lateral border fuses with the proximal peripheral zone border at the prostate base.
It has the shape of an inverted cone with its base oriented towards the base of the
gland. It contains about 20% of the glandular tissue. It contains more stroma than
glandular tissue. The term central gland refers to the central zone and the transition
zone combined. The use of this term is discouraged. If the central zone is not seen
as a distinct regional part, then a finding in this region should be localized to
the transition zone.;
