Prostate Mri Anatomy

The majority of cancers arise from the peripheral zone pz. Special techniques are used to improve the early detection of prostate cancer such as dwi dynamic contrast enhanced mri and mr spectroscopy.

Prostate mri anatomy. From superior to inferior the gland is commonly divided into 3 levels. Positive digital rectal exam dre and negative trus biopsy. Mri imaging is helpful in differentiation the prostatic zonal anatomy best demonstrated on t2wi.

Coronal axial sagittal anatomy. The best anatomic detail is on small fov t2wi. Mr imaging of the prostate gland.

There is no ionizing radiation x rays used to create any mri image. Prostate anatomy on mri. 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. Prostate mri is for men who have. Define benign prostatic hypertrophy.

Elevated or rising prostate specific antigen psa and at least one negative transrectal ultrasound guided trus biopsy. Pi rads version 2 prostate imaging reporting and data system applying pi rads scoring in the peripheral zone and transition zone. 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.

Evaluating sequential sections the peripheral central and transition zones could be differentiated. What sequences to use. Mri of the prostate has become increasingly popular with the use of multiparametric mri and the pi rads classification.

A prostate cancer diagnosisto provide accurate staging and guide treatment options or assess disease progression. Below an example of a prostate with minimal bph 30 ml entire gland. The peripheral zone showed higher signal intensity than either the central or transition zone and was discerned in the coronal sagittal and transverse planes.

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.
