Ultrasound and Magnetic Resonance Imaging (MRI) are used predominantly in prostate cancer care in terms of tumor characterization, staging, presurgical and radiation therapy planning, therapy monitoring, and follow-up.
Transrectal Ultrasound (TRUS)
The gold standard for diagnosis of prostate cancer is the histological assessment of specimens obtained by TRUS-guided systematic core needle biopsy. The method involves taking tissue samples from the prostate in a geometric pattern.
Advanced ultrasound options, such as color power Doppler and contrast-enhanced ultrasound, offer increased sensitivity and specificity for lesion detection and localization.
Real-time elastography represents a further ultrasound technique that can help differentiate malignant from benign tissue for lesion detection and biopsy guidance.
Multi-parametric MRI is used for tumor localization and delineation in a number of scenarios. Examples include negative TRUSguided biopsy with continued rise of PSA, relapse after initial therapy, local staging, and therapy planning.
Siemens offers a full range of tumor staging and optimized prostate MRI applications such as syngo.MR General Engine Prostate Workflow & Report.
A range of dedicated body, spine and endorectal coils are offered for the MAGNETOM 1.5 Tesla and 3 Tesla systems for optimized image quality.
