“…Herein, the computer-aided registration of the needle location during real-time TRUS (or MRI or fusion) provides a precise spatial record of 3D location of every biopsy core. [ 69 ] This allows the operator to perform the repeat biopsies only from the previously non-sampled areas. This biopsy technique is thought to be more precise than the external template-based guided approaches.…”

Prostate cancer is the commonest malignancy in men that causes significant morbidity and mortality worldwide. Screening by digital rectal examination (DRE) and serum prostate-specific antigen (PSA) is used despite its limitations. Gray-scale transrectal ultrasound (TRUS), used to guide multiple random prostatic biopsies, misses up to 20% cancers and frequently underestimates the grade of malignancy. Increasing the number of biopsy cores marginally increases the yield. Evolving techniques of real-time ultrasound elastography (RTE) and contrast-enhanced ultrasound (CEUS) are being investigated to better detect and improve the yield by allowing “targeted” biopsies. Last decade has witnessed rapid developments in magnetic resonance imaging (MRI) for improved management of prostate cancer. In addition to the anatomical information, it is capable of providing functional information through diffusion-weighted imaging (DWI), magnetic resonance spectroscopy (MRS), and dynamic contrast-enhanced (DCE) MRI. Multi-parametric MRI has the potential to exclude a significant cancer in majority of cases. Inclusion of MRI before prostatic biopsy can reduce the invasiveness of the procedure by limiting the number of cores needed to make a diagnosis and support watchful waiting in others. It is made possible by targeted biopsies as opposed to random. With the availability of minimally invasive therapeutic modalities like high-intensity focused ultrasound (HIFU) and interstitial laser therapy, detecting early cancer is even more relevant today. [18F]--fluorodeoxyglucose positron emission tomography/computed tomography (18FDG PET/CT) has no role in the initial evaluation of prostate cancer. Choline PET has been recently found to be more useful. Fluoride-PET has a higher sensitivity and resolution than a conventional radionuclide bone scan in detecting skeletal metastases.

The combination of T2-weighted MRI with functional MRI, including contrast-enhanced MRI, diffusion-weighted imaging and magnetic resonance spectroscopy, has been recognized as the most promising diagnostic modality for the detection and staging of localized prostate cancer. In spite of the relatively low predictive value of the transrectal ultrasonography (US) image alone, transrectal US-guided prostate biopsy is currently the most clinically used, gold standard technique to confirm pathological prostate cancer. A possible way of improving the precision of prostate biopsy is to use computer-aided analysis, the fusion of the US image with MRI, or by introducing contrast-enhanced US, elastography and/or 3D US to be coupled with computer-assistance or robotic needle placement. Computer-aided surgical navigation systems with image-fusion or image-overlaying capability, integrated with real-time organ tracking systems and/or robotic systems for feedback on the 3D spatial positions of the surgical targets and instruments, can provide attractive opportunities to improve the digitally-coordinated precision of minimally invasive urology, along with predictive ability to guide toward ideal surgical outcomes.
