Diagnostic Evaluation of Prostate Cancer with 3D Ultrasound

The prostate, a motionless and small organ is ideal for 3D ultrasound as this organ can bee covered in a single acoustic area. It helps to acquire volume data more accurately and more rapidly.
Transrectal ultrasound is used for accurate volume measurements of whole prostate in transitional zone. Approximately 20% error has been measured in 2D transrectal ultrasound.3D ultrasound gives the volume in accuracy even in irregularly shaped structures.
Gray-scale 3D transrectal ultrasound increases both sensitivity and specificity of prostate cancer evaluation, due to better visualization of gland and focal lesions.
Color Doppler and power Doppler can aid the detection. 3D Doppler ultrasound increases the likelihood of positive Biopsy.
Signs of extracapsular extension can be seen more clearly on3D Doppler Ultrasound.
Contrast enhancement is used for diagnostic accuracy of 2D ultrasound.
Unlike the 2D approach, evaluation is not restricted to the axial plane.
Contrast-enhance power Doppler 3D ultrasound can increase the diagnostic accuracy of prostate cancer imaging from 61% to 86%.
