Learning objectives
To show the latest technological advancements in real-time Transrectal Ultrasound (TRUS) fusion imaging for Prostate diagnostics and biopsy real-time guidance.
Background
Prostate cancer is the most common cancer and the second most common cause of cancer deaths among men in the western countries [1].
The management of prostate cancer is a complex issue because of the difficulty in accurate staging and in predicting the speed of disease progression [2].
The current methods of prostate cancer detection include digital rectal examination (DRE),
serum prostate-specific antigen (PSA) level and TRUS with random biopsy [3].
The role of Magnetic Resonance Imaging (MRI) has evolved over the past decade with...
Findings and procedure details
In recent years real-time Ultrasound image fusion with a pre-acquired second imaging dataset has become more common also in prostate diagnosis and biopsy guidance [17,
3,
18].
In our experiences,
real-time fusion imaging was carried out by MyLabTwice Ultrasound system (Esaote S.p.A.,
Genova,
Italy – Fig.
8) equipped with Virtual Navigator technology.
The endocavity probes used were TRT33 and EC1123.
TRT33 (Fig.
9) is Transrectal probe with a dual transducer: a Microconvex (6.5MHz center frequency) and a Linear array (7MHz center frequency) positioned along the...
Conclusion
In our experience,
real-time Fusion Imaging with Virtual Navigator technology was mainly used in TRUS for Urology application regarding:
· Real-time biopsy guidance by the Virtual Biopsy tool,
for needle path visualization in order to target and plan needle path,
using any second imaging modality (MRI,
PET/CT).
· Everyday Clinical Practice - fusion imaging technology needs only a slight increase in time in order to be ready for real-time navigation.
With the possibility to use also previously acquired MRI and/or PET/CT of the examined subject,...
