What is Fusion Biopsy?
Fusion biopsy is an innovative biopsy technique that combines pre-biopsy magnetic resonance imaging (MRI) with real-time ultrasound during the biopsy procedure. This technology helps urologists more accurately target and sample suspicious areas seen on the MRI.

How does it work?
During a Fusion Biopsy, the patient first undergoes an MRI scan of the prostate. This high-resolution imaging identifies any abnormal growths or areas of concern. Then, using sophisticated computer software, the MRI images are co-registered or "fused" with real-time ultrasound images obtained during the biopsy. This allows the urologist to use the ultrasound to visually guide the needles to precisely target the areas previously identified on MRI.

Targeting with Precision
One major advantage of fusion biopsy is its precision. MRI has been shown to detect more significant cancers than standard ultrasound-guided biopsy alone. Fusion technology allows doctors to precisely direct biopsy needles to the specific regions highlighted on the pre-biopsy MRI. This targeted approach optimizes detection of clinically significant cancers while avoiding unnecessary sampling of less concerning areas.

Improving Detection Rates
Numerous clinical studies have found fusion biopsy detects significantly more high-grade cancers compared to standard biopsy. One trial showed fusion biopsy increased the detection of Gleason Score 7 or higher cancers by over 30%. Other reports found it nearly doubled the detection of posterior zone cancers traditionally missed by standard biopsy. Its targeted approach optimizes identification of cancers most likely to spread.

Reducing Overdiagnosis
Along with improved detection, fusion biopsy may reduce overdiagnosis of indolent, low-risk cancers unlikely to threaten a man's health. Since only suspicious areas highlighted on MRI are sampled, it reduces unnecessary detection of minimal cancer foci of no clinical significance. This "risk-stratified" biopsy approach avoids overtreatment with its associated harms and unnecessary costs.

Streamlining Biopsy Evaluation
Traditional biopsy relies on randomly sampling the prostate, leading to evaluation of numerous benign cores. In contrast, fusion biopsy results in evaluation of fewer but more relevant specimens. A recent study found pathologists needed only evaluate half as many cores per patient compared to standard biopsy, streamlining resource utilization in pathology. Doctors can focus exclusively on areas likely to contain higher-risk cancer needing treatment.

Is it Cost Effective?
While the upfront cost of a fusion system is higher than with standard biopsy, emerging data suggests fusion biopsy could lower costs over the long run. Its targeted approach may reduce unnecessary repeat biopsies, overtreatment of low-risk disease, and costs of managing side effects of overtreatment. One decision analysis found if fusion biopsy prevented even one patient from undergoing unnecessary treatment, it would outweigh the costs of purchasing the system. As adoption increases, costs are expected to decline.

The Future of Fusion Biopsy
As the technology evolves, new developments are enabling even more precise targeting. Some systems now offer in-gantry, real-time MRI-ultrasound fusion, avoiding the need to transfer pre-biopsy images between rooms. Artificial intelligence tools are being integrated to automate co-registration. Portable, lower-cost biopsy systems are being developed for community urology practices. Ultimately, fusion biopsy represents an important step towards personalized, risk-stratified prostate cancer diagnosis and management tailored to each individual patient's disease burden and life expectations.
