摘要

目的：

探讨融合成像在超声阴性MRI阳性前列腺癌穿刺活检中的应用价值。

方法：

选取行超声引导下穿刺活检的前列腺癌患者4例，术前1周MRI检查可疑前列腺癌病灶5个，而经直肠前列腺超声为阴性。采用图像融合技术，对MRI可疑前列腺癌病灶进行穿刺。

结果：

4例患者5个MRI可疑前列腺癌病灶穿刺结果显示，4个病理诊断为前列腺癌，1个病理诊断为前列腺增生，诊断阳性率为80%。

结论：

图像融合能提高超声阴性前列腺癌穿刺的阳性率。

Abstract

Objective:

To investigate the application value of MRI-ultrasound fusion prostate biopsy in patients with negative ultrasound findings.

Methods:

Four cases with prostate cancer who underwent ultrasound-guided biopsy were selected. All cases underwent MRI examination 1 week before surgery and had the manifestations of suspicious prostate cancer which were not found by ultrasound. MRI-ultrasound fusion prostate biopsy was applied in the diagnosis of prostate lesions.

Results:

Four cases had 5 suspicious prostate lesions. There were 4 lesions diagnosed as prostate cancer

and 1 lesion diagnosed as benign prostatic hyperplasia. The positive rate was 80%.

Conclusion:

MRI-ultrasound fusion prostate biopsy can improve the positive rate of prostate cancer in the patients with negative ultrasound findings.
