Objectives: After studying the article entitled “Transrectal Elastographic Biopsy and Contrast-Enhanced Transrectal Biopsy May Offer Improvements Over the Current Transrectal Systemic Biopsy Technique,” you will be able to:
Describe current techniques used for transrectal biopsy
Evaluate the sonographic appearance of the prostate gland
Determine appropriate sonographic techniques to evaluate the prostate gland
The sensitivity of conventional gray-scale sonography to prostate cancer is reported to be approximately 27% 44% 77% 80%
By conventional gray-scale sonography, prostate tumors are likely to be Hypoechoic Isoechoic Hyperechoic Hypoechoic, isoechoic, or hyperechoic
Using the elastography stiffness scoring system adapted from Kamoi et al, a score of 4 would indicate a lesion that is Probably carcinoma Indeterminate Probably normal Normal
On a per patient basis, the sensitivity of contrast-enhanced transrectal ultrasound-guided prostate biopsy has been reported to be approximately 50%–90% 65%–80% 80%–100% 72%
Prostate cancer occurs nearly _________ in African American men compared to other groups. With the same frequency Twice as often Three times as often Five times as often
On a per patient basis, the sensitivity of transrectal elastography to guide prostate biopsy has been reported to be approximately 40%–80% 50%–90% 60%–70% 20%–50%
The addition of color and power Doppler imaging to conventional gray-scale imaging for the detection of prostate cancer Improves sensitivity Improves specificity Improves sensitivity and specificity Has had mixed results in detection accuracy
From 2006 to 2014, the death rate from prostate cancer decreased approximately 3% 5% 8% 18%
Standard cutoff values for prostate specific antigen levels have a false positive rate of approximately 14% 18% 27% 80%
At least one minor complication occurs related to transrectal ultrasound-guided prostate biopsy in approximately ______ of patients. 3% 5% 9% 14%
