Abstract:
Objective:To compare the values of medical image technologies in evaluating the tansperineal laser ablation (TPLA) in canine prostate.Methods:TPLA (3 W/600 J and 3 W/1 200 J) were operated in the prostate of six adult male beagles guided by transrectal ultrasound (TRUS). TRUS, transrectal contrast-enhanced ultrasound (TR-CEUS) and multiparameter magnetic resonance imaging (mpMRI) were used to evaluate the ablation on the day of TPLA, one week and one month after TPLA. The animals were sacrificed for pathology to calculate the volume of the ablation. SPSS 22.0 software was used for statistical analysis.Results:TRUS could be used to guide and observe the puncture and ablation process during TPLA. TR-CEUS and contrast enhanced MRI showed good consistency in the volume of ablation ( P>0.05). One month after TPLA, the ablation volume were (1.69±0.51)ml vs (1.73±0.36)ml vs (1.52±0.41)ml (3 W/600 J) and (2.23±0.54)ml vs (2.34±0.29)ml vs (2.19±0.34)ml (3 W/1 200 J) measured by the two medical image technologies and pathology, with good consistency ( P>0.05). Conclusions:TRUS can be used to guide and observe the puncture and ablation process during TPLA. TR-CEUS and mpMRI can be used for postoperative evaluation and follow-up of TPLA. The former has advantages of real-time and low price, which can be promoted and applied in clinical practice.
