Anatomy & Morphology

Diagnostic confidence, patient after patient.

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)

Live Bi-Plane BP9-4 Transducer provides live and simultaneous, sagittal and transversal visualization of the prostate gland.
  • 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.   

Magnetic Resonance Imaging (MRI)

  • 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.
