1. PIN在超声上可表现为低回声病变。2.活检结果证明PIN与癌症之间存在密切关系。3.诊断PIN的年龄、病变大小和PSA测量值介于非癌症和癌症之间。4.现在可以对低回声病变进行连续、精确的经直肠超声引导活检，因此可以对诊断为PIN的患者进行密切随访。
1. PIN can present as a hypoechoic lesion on ultrasound. 2. Biopsy results prove a close relationship between PIN and cancer. 3. Measurements of age, lesion size, and PSA for diagnoses of PIN were intermediate values between non-cancer and cancer. 4. Sequential, precise transrectal ultrasound-guided biopsies of hypoechoic lesions are now possible, and close follow-up of patients with diagnoses of PIN is therefore possible.
