目的探讨超声造影(CEUS)经直肠超声弹性成像(TRE)在判定为Ⅲ级的前列腺结节中的临床使用价值,及结节深度对TRE和CEUS鉴别诊断该种前列腺结节的影响。方法对89个经TRE判定为Ⅲ级的前列腺结节按其距探头的深度(D)不同,分为A组(D<10mm)、B组(10mm≤D<20mm)及C组(D≥20mm),对上述3组结节进行CEUS并以靶向穿刺的病理结果为金标准,评价CEUS对该种前列腺结节的诊断价值,并评价结节深度对TRE及CEUS诊断该种结节的良恶性有无影响。结果 TRE的诊断符合率在A组与C组之间存在差异并具统计学意义(P<0.05);CEUS的诊断符合率在不同深度组之间均无统计学差异(P>0.05)。结论前列腺结节的深度影响TRE的诊断符合率;CEUS的临床应用有利于该种前列腺结节的进一步鉴别诊断。
Objective To investigate the clinical value of ultrasonography (CEUS) transrectal ultrasound elastography (TRE) in the diagnosis of grade Ⅲ prostatic nodules and the effect of nodule depth on the differential diagnosis of prostatic nodules by TRE and CEUS. Methods 89 prostatic tubercles treated with TRE as grade Ⅲ were divided into group A (D <10mm), group B (10mm≤D <20mm) and group C (D≥ 20mm). CEUS was performed on the above three groups of nodules and the gold standard was used as the gold standard to evaluate the diagnostic value of CEUS for the type of prostate nodules. The depth of nodules was evaluated for the diagnosis of such nodules by TRE and CEUS Whether benign or malignant Results The diagnostic coincidence rate of TRE was significantly different between group A and group C (P <0.05). There was no significant difference between the two groups in the diagnostic accuracy of CEUS (P> 0.05). Conclusion The depth of the prostatic nodule affects the diagnostic accuracy of TRE. The clinical application of CEUS is helpful for the further differential diagnosis of this kind of prostatic nodules.
