Abstract:
Background
In prostate cancer, detection of seminal vesicle involvement is important because it influences the treatment planning and prognosis of the patients.Objectives
The objective of this study was to determine the value of prostate MRI with endorectal coil in the detection of seminal vesicle involvement in patients with prostate cancer.Patients and Methods
A total number of 238 biopsy-proven prostate cancer patients were examined by 1.5 Tesla MRI with a combination of pelvic and endorectal coils to detect seminal vesicle involvement. After radical prostatectomy, the MRI results were compared with pathology results.Results
Seminal vesicle involvement was detected in 67 (28.1%) patients. Pathology confirmed the involvement of seminal vesicles by prostate cancer in 63 patients. In two patients, seminal vesicle involvement was diagnosed by pathology but not detected by MRI. The sensitivity was 0.97 [95% confidence interval = 0.89-0.99], the specificity was 0.98 [95% confidence interval = 0.94-0.99], the positive predictive value was 0.94 [95% confidence interval = 0.85-0.98], and the negative predictive value was 0.99 [95% confidence interval = 0.96-0.99].Conclusions
MRI with endorectal coil is a valuable imaging technique with suitable accuracy in detecting seminal vesicle involvement in prostate cancer.Keywords:
