Abstract
Purpose: to define diagnostic possibilities of Magnetic Resonance Imaging (MRI) with body coil in the determining of the stage and local extent of prostate cancer.
Materials and methods: Analysis of MRI studies of 49 patients aged from 48 to 78 (65±6) with confirmed diagnosis of prostate cancer who underwent radical retropubic prostatectomy in 2007 was carried out.
Conclusions: sensitivity of MRI in terms of primary diagnosis was 84% and in detection of prostate gland capsule invasion — 62%, specificity was 92%. Sensitivity of the method in terms of determining the invasion of seminal vesicles was 75% and specificity — 97%. At last, sensitivity of the method in the diagnosis of regional lymph node involvement was 40% and specificity — 98%.
Conclusion: application of MRI with surface coil allows defining the local extent of the tumor, its size and invasion of prostate gland capsule.
