Comparative study of the sectional slice of the prostate zone with its MRI images
Objective To compare morphological features of the prostate zones with its corresponding MRI images, and provide anatomical basis for MRI diagnosis of prostate zone diseases. Methods Prostate area of 576 normal persons and 6 cadaveric specimens were performed MRI scan and image analysis. And then, series sections of cadaveric prostate zone were prepared by using celloidin embedding method, for the comparative studying of MRI images and morphologic features. Results On the sectional specimens, periphery zone, central zone, transitional zone, paraurethral gland zone and fibrous muscle zone of prostate can be roughly identified according to the anatomic location of urethra, seminal crest and ejaculatory duct. On MRI images, outline of prostate presented clearly on T1WI condition, and periphery zone of prostate showed higher signal than that of central zone. The sectional data could be corresponded to MRI data completely. Conclusions To scan and analyze prostate zones through transversal, coronal and sagittal scan is helpful for accurate diagnosis and allocation of intraprostatic diseases.
