summary

Introduction and the aim of the study. MR using endorectal coil is a method of diagnostic imaging, allowing accurate presentation of prostate morphology, including differentiation of peripheral zone and central gland. Currently, it enables not only morphological imaging, but also assessment of metabolic disturbances and microcirculation abnormalities resulting from the presence of neoplasm. For a high cost and limited accessibility of MR, it is necessary to rationally determine its position in the algorithm of prostate cancer diagnostics and therapy. The aim of the study is to present modern possibilities of MR in the diagnostics of prostate cancer.
Material and method. On the basis of literature analysis, the current role of MR in the diagnostics and therapy of prostate cancer was determined. The currently available methods of prostate MR and their practical applications were presented.
Results. The MR technique in patients with suspected or confirmed prostate cancer at present includes not only morphological MR, but also MR spectroscopy, dynamic contrast enhanced MR and diffusion MR. Existing applications include, among other things: location of cancer focus in patients with both TRUS and sextant biopsy negative, tumor staging including extracapsular extension and the presence of metastatic pelvic lymph nodes and bone foci, optimization of radiotherapy, search for relapse, evaluation of hormone-deprivation therapy, biopsy under the MR guidance.
Conclusion. MR imaging using endorectal coil is a technique, useful both in the diagnostic process and in the therapy of prostate cancer, providing urologists with valuable information concerning not only morphological abnormalities, but also metabolic and microcirculation disturbances. Broader use of existing prostate MR possibilities is recommended, both in common urological practice and in scientific research.
