In these patients dr sperling utilizes power doppler sonography ultrasound of the prostate a non invasive way to evaluate for prostate tumors with their abnormal blood vessels without contrast dr sperling will then fuse these ultrasound images onto the non contrast mri study as imaging improves so does prostate cancer detection . 3 d color flow doppler ultrasound the dattoli cancer center uses the most sophisticated hitachi scanner with a custom true 3 d color flow doppler application incorporating advanced state of the art ultrasound technology called elastography which analyzes tissue densities to differentiate between cancerous and benign tissue technically referred to as transrectal ultrasonography . In addition to more precise measurements of the prostate the color doppler imaging technology can more accurately detect subtle abnormalities in the prostate by looking at the blood flow patterns prostate disease often results in an increase in blood flow to the affected area which the color imagining was made for reading. Tag color doppler ultrasound high resolution color doppler ultrasound is really two scans in one a grey scale image in black and white and a color image that detects areas of increased blood flow prostate cancer shows up as a dark area on grey scale imaging or as an area of increased flow on a color doppler ultrasound. Ultrasound imaging of the prostate is commonly used to assess the size of the gland and for needle placement during systematic biopsy ultrasound evaluation of prostate cancer is limited by difficulty in distinguishing benign from malignant tissue although doppler techniques may provide some
