The prostate gland is a small soft structure about the size and shape of a walnut which lies deep in the pelvis between the bladder and the penis and in front of the rectum back passage.
Mri prostate anatomy. Prostate mri captures detailed images of the prostate to evaluate for prostate cancer or disease. Using computer aided detection cad this exam can pinpoint specific areas within the prostate gland that are suspicious and may require further evaluation. The majority of cancers arise from the peripheral zone pz.
There is no ionizing radiation x rays used to create any mri image. The peripheral zone showed higher signal intensity than either the central or transition zone and was discerned in the coronal sagittal and transverse planes. Small bph nodule at r base at the centralperipheral zone border benign prostate hyperplasia bph typically arises in the transition zone distorts zonal anatomy and can get very large over 200 ml.
Multiparametric mri is a combination of t2 weighted diffusion and dynamic contrast enhanced imaging and is an accurate tool in the detection of clinically significant prostate cancer. A magnetic resonance imaging mri scanner uses strong magnetic fields to create an image or picture of the prostate and surrounding tissues. An mri study of the prostate incorporates a powerful magnet system radio waves and a computer to create very detailed images of the prostate gland and surrounding anatomy.
Mr imaging of the prostate gland. Evaluating sequential sections the peripheral central and transition zones could be differentiated. Prostate hyperplasia bph less commonly occurs outside of the transition zone.
Mri for diagnosis and treatment of prostate cancer duration. An mri is a test that produces very clear pictures of the human body without the use of x rays. Instead mri uses a large magnet radio waves and a computer to produce these images.
Special techniques are used to improve the early detection of prostate cancer such as dwi dynamic contrast enhanced mri and mr spectroscopy. As health systems around the world adopt mri as the preferred method to assess diagnose and monitor the progression of prostate cancer the demand has increased for detailed educational material for radiologists who read prostate mrs. Mri imaging is helpful in differentiation the prostatic zonal anatomy best demonstrated on t2wi.
Mri of the prostate has become increasingly popular with the use of multiparametric mri and the pi rads classification. In prostate cancer patients mri may be used to examine the prostate and nearby lymph nodes to distinguish between benign noncancerous.
