Imaging characteristics of prostate cancer by transrectal ultrasound and color Doppler ultrasonography
Release date: 2015-04-09
Recently, Wang Peng, from Feixian Hospital of Traditional Chinese Medicine in Shandong Province, studied the imaging features of prostate cancer by transrectal ultrasound and color Doppler ultrasonography. The study found that the imaging features of prostate cancer were detected by transrectal ultrasound and color Doppler ultrasonography. Obviously, it can further improve the diagnostic level and diagnostic accuracy of prostate cancer, and it is worthy of clinical application. The article was published in the 2014 issue of China's Pharmaceutical Economics.
The aim of this study was to investigate the imaging features of prostate cancer by transrectal ultrasound and color Doppler ultrasound.
The investigators selected 46 patients with prostate who were admitted to our hospital from November 2011 to November 2013. All patients underwent TRUS guided puncture. 18 patients were confirmed to have prostate cancer, and the remaining 28 patients were confirmed to be prostate. Hyperplasia.
The results showed that the TRUS images of 18 patients diagnosed with prostate cancer showed a "map-like" change in the prostate, with strong echogenic nodules mixed, echoes varying in intensity, blurred boundaries, and multiple hypoechoic The area will have a sonogram, the structure echo is obviously disordered; the outer gland is obviously thickened, the inner and outer glands are unclear, the prostate capsule is incomplete, and the shape is abnormal. The prostate showed diffuse distribution in the marginal zone and transitional zone, and some of the sand-like calcifications were clustered. There were 13 cases of this sign in this group of patients. The sonogram of 28 patients diagnosed with benign prostatic hyperplasia was characterized by strong echogenic calcification in the prostate site, usually at the junction of the inner and outer glands or the inner gland, showing a large strong echogenic nodule. The cystic nodules can be seen inside the prostate. The borders are still regular, but the indications are unclear. The echoes of the inner glands are slightly stronger than the echogenic nodules. The echoes are uneven, and the strength is different. It is obviously protruding toward the bladder, partially dysfunctional, and full in shape. The outer gland is obviously compressed and thinned, and the boundary between the inner and outer glands is still clear.
