研究概览

简要总结

The purpose of our study is to image human prostate tissue using a transrectal photoacoustic imaging probe.

详细描述

PRIMARY OBJECTIVE(S):

The primary objective of this pilot study is to assess PAI-performance in a clinical setting to understand limitations of our current PAI instrumentation and to help improve the next-generation design.

SECONDARY OBJECTIVE(S):

To do preliminary evaluations of oxygen saturation in lesions based on PAI-measurements in order to distinguish malignant from benign prostatic tissue as a basis for future studies.

入选标准

  • Consent signed
  • Male >= 18 and <= 80 years of age
  • Patients must have an elevated PSA And/ Or Abnormal digital rectal exam Or Other indication for prostate biopsy Or Patients with biopsy proven prostate cancer who are scheduled for prostatectomy.

排除标准

  • History of prostatectomy or other surgical history that would preclude transrectal imaging (i.e. abdominal perineal resection), anal stenosis/stricture disease
  • Men with anatomic abnormalities or previous surgical history that make transrectal imaging impossible (for example, men with previous abdominal-perineal bowel resections or anal atresia/stenosis)

结局指标

主要结局

lesion signal intensity on Photoacoustic Imaging (PAI) in relation to different lesion characteristics and the surrounding tissues

时间窗: 36 months

measure of the lesion signal intensity on PAI in relation to different lesion characteristics and the surrounding tissues. The average signal intensity (or more specifically the SNR) of the lesions measured in dB) will be tabulated against lesion depth from the transducer, and lesion size, based on ultrasound measurements

次要结局

  • Measures of hypoxia in the lesion(36 months)
