Abstract

Purpose: Evaluate the efficiency of transrectal strain elastography (SE) and transrectal B-mode ultrasonography (TRUS) in determining prostate cancer.
Material & Methods: From 20/6/2015 to 10/9/2015, There are 101 patients with PSA level of higher 4ng/ml have been selected. Abnormal echo regions in
prostate were found via conventional TRUS in those patients, then Abnormal echo regions would be evaluated by real-time strain ultrasound elastography.
Patients have undergone six core biopsies by transperineal approach. Experimental studies
Results: Comparising between 3 methods: B-mode TRUS, strain elastography and DRE about sensitivity, specificity, positive predictive value (PPV) and
negative predictive value (NPV). (table)
Table.Comparising between 3 methods: B-mode TRUS, strain elastography
and DRE.
                           Sensitivity(%)                         Specificity(%)                                    PPV(%)                                NPV(%)
B-mode                    88.5                                          55.1                                                67.6                                  81.8
Strain-elasto            94.2                                         65.3                                                74.2                                   91.4
DRE                           69.2                                         98                                                    98                                      75
Conclusions: Sonoelastographyprovidesmore information to detect prostate cancer and biopsy guidance. SE reached a higher sensitivity and specificity than B-mode US in the detection prostate cancer.Strain ultrasound elastography can be used as routine as colour Doppler
