November These MRI sequences are interpreted by a Prosyata radiologist, with expertise in screening for and identifying the presence of potential cancer sites within the prostate.

In KOELIS, we innovate every day in collaboration with world-renowned universities and hospitals to offer physicians new advancements in imaging and a greater field of view in order to bring personalized answers to every patient, irk the respect of their quality of life.
Clinical accuracy is at the heart of our technology. Our 3D transducers combined with exclusive OBT Fusion® technology detects the slightest patient movement and prostate deformation for an accurate guidance and recording of the procedure. KOELIS Trinity® innovative and intuitive interface elevates fusion biopsy to new levels of productivity by making exams faster and reliable. KOELIS, the prostate care company, based on the value of 3D imaging and unique patient-tailored cartography, proposes new concepts and guidelines in prostate care management.
Over , Easily integrated in routine clinical practice, KOELIS Trinity® supports both transrectal and transperineal sampling approaches even under local anesthesia. Simon BOTT. Follow Follow Follow Follow. If local anesthetic is satisfactory, discomfort is minimal. Since the mids, TRUS biopsy has been used to diagnose prostate cancer in essentially a blind fashion because prostate cancer cannot be seen on ultrasound due to poor soft tissue resolution. However, multi-parametric magnetic resonance imaging mpMRI has since about been used to better identify and characterize prostate cancer.
When MRI is used alone to guide prostate biopsy, it is done by an interventional radiologist. In the fusion MRI-US prostate biopsy, a prostate MRI is performed before biopsy and then, at the time of biopsy, the MRI images are fused to the ultrasound images to guide the urologist to the suspicious targets. Several groups in the U. Considerable experience and training is required by the reader of prostate mpMRI studies.
The tissue samples are examined under a microscope to determine whether cancer cells are present, and to evaluate the microscopic features or Gleason score of any cancer found. Gleason score, PSA, and digital rectal examination together determine clinical risk, which then dictates treatment options. Tissue samples can be stained for the presence of PSA and other tumor markers in order to determine the origin of malignant cells that have metastasized. From Wikipedia, the free encyclopedia.

September PMC PMID A PI-RADS score from 1 to 5 — indicating the probability of clinically significant cancer is then attributed by the specialist radiologist to each of the suspicious areas identified.
The MRI provides a good negative predictive value , such that a test performed by a specialist radiologist, concluding upon the absence of suspect areas, may constitute a sufficient reason to defer the biopsy 1. Nonetheless, in conjunction with MRI, guided biopsy remains the only conclusive method of diagnosing prostate cancer. Once interpreted, the MRI scans are sent to the urologist. Source: Nima Nassiri et al. Video originally uploaded on Intbrazjurol. As the suspect areas detected during the MRI do not appear on the ultrasound images, precise targeting of the biopsies is not guaranteed. This consists of digitally superimposing the MRI scans onto the ultrasound images.
Suspect areas detected by the MRI are thereby displayed on the ultrasound scanner, allowing the urologist to target the necessary biopsies.
Results: Cores obtained with the fusion technique achieved a higher precision than cores obtained from cognitive techniques 2. Fewer cancers were detected with the cognitive technique than with the fusion technique. The precise overlay fusion of MRI-ultrasound images is essential in order to guarantee that the potential cancer sites are targeted during a biopsy. The prostate is a supple and mobile organ — During a biopsy, the endorectal ultrasound probe and patient movements cause deformations of the organ. The delay between the MRI and biopsy procedure — The prostate is an organ that changes over time for example, enlargement. As such, elastic fusion is the only method that enables the accurate display of the suspect areas previously identified by the MRI. Recent studies have proven that Elastic fusion are more effective than rigid fusion:
During the course of a biopsy, the prostate becomes deformed and displaces itself in relation to its initial position pressure exerted by the probe, patient movements, etc. Unlike other technologies that track the movement of the probe robotic technology or electromagnetic sensors , OBT Fusion® tracks the shifting prostate and automatically compensates for these movements therefore maximising the accuracy of the procedure. Software-based MRI-US fusion guided biopsy marks a turning point in prostate cancer care for a number of reasons. According to the latest directions, the early use of multiparametric magnetic resonance imaging mpMRI before a prostate biopsy is recommended in both biopsy naïve patients and in patients with a prior negative biopsy for the detection of prostate cancer.
Using magnetic resonance imaging MRI as an initial test for suspected prostate cancer patients is now recommended by the French Urology Association. Regarding patients with prior biopsy, the performance of a mpmri multiparametrical MRI before another biopsy session is recommended.
Multiparametric MRI scan before biopsy is also recommended for patients with clinically significant prostate cancer since it helps to locate the cancer and to target it directly.

The first option offers high precision targeting but is limited by the accessibility, cost and duration of Proostata procedure. Biopsies targeting suspicious areas on MRI are promising to improve the sensitivity and performance of prostate biopsies.
