Experimental investigations were carried out under in vitro conditions on 25 normal human testicular specimens and on 60 pathological testicular specimens to ascertain the ultrasound attenuation using an ultrasound spectroscopic measuring technique. The ultrasound attenuation was established by calculating the ultrasound attenuation coefficient alpha. The average values of ultrasound attenuation (alpha) in normal testicular tissue were distinctly lower than in pathologically altered testicular specimens. A comparison of the various pathologically altered testes showed higher attenuation in the case of malignant neoplasms whilst the highest average values of wore recorded for non-neoplastic pathological alterations in the testicular tissue. The results of the investigations show that certain alterations in the tissue can be ascertained by ultrasound spectroscopy. The analysis of further acoustic parameters in future investigations, such as ultrasound back-scattering and velocity, along with the recording of ultrasound attenuation, gives scope for improved assessment of the tissue. Thus ultrasound spectroscopy increases the sonographic accuracy acquired through analysis and the weighing up of symptoms of tissue dependent ultrasound parameters.
在体外条件下，对25份正常人体睾丸标本和60份病理睾丸标本进行了实验研究，以使用超声光谱测量技术确定超声衰减。通过计算超声衰减系数α来确定超声衰减。正常睾丸组织中的超声衰减（α）平均值明显低于病理改变的睾丸标本。对各种病理改变的睾丸进行比较发现，恶性肿瘤情况下的衰减更高，而睾丸组织中非肿瘤性病理改变的平均衰减值最高。研究结果表明，组织中的某些改变可以通过超声光谱法确定。在未来的研究中，对诸如超声背散射和速度等进一步声学参数的分析，以及超声衰减的记录，为改进组织评估提供了空间。因此，超声光谱法提高了通过分析和权衡与组织相关的超声参数症状所获得的超声检查准确性。
