Transrectal sonoelastography in detection of prostatecancer: initial assessment of 101 cases
Main Article Content
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
