Focalyx Bx

A new philosophy in the diagnostic accuracy of prostate cancer

FOCALYX® Bx assures the most accurate diagnosis of prostate cancer thanks to fusion biopsy.

We combine the images extracted from the multi parametric magnetic resonance (FOCALYX® Dx) that we make thanks to our high precision scanner with those obtained directly thanks to an ultrasound.


In this way, we get a 360° map of the prostate that helps us identify the exact points where the patient’s biopsy shall take place.

More precise diagnosis in comparison with other procedures

Regarding the advantages of this technique over others, the information speaks for itself. The US National Cancer Institute analyzed 1,003 men with suspected prostate cancer who underwent both tests: traditional biopsy and fusion. The results of the study were conclusive: the location of aggressive tumors was 30% higher with the fusion biopsy.

Accurate tumor detection including the most difficult areas

Prostate biopsy guided by image fusion RM-ECO

Ultrasound and magnetic resonance imaging (MRI) are the two main imaging techniques used to help diagnose PC. The use of multi parametric MRI 1.5 / 3T represents a great advance in its detection and diagnosis due to its superior resolution against ultrasound.

The fusion, a revolutionary image technique

The fusion is a process that combines the images obtained from multi parametric magnetic resonance with those obtained directly thanks to a prostate ultrasound.


The outline of the prostate is introduced into a computer system (fusion software) to carry out the superimposition of both silhouettes, that obtained through nuclear magnetic resonance and that of ultrasound.


The result is a highly accurate 3D image of the patient’s gland, in which it is possible to locate suspicious lesions with GPS with great precision.

How is the process performed?

We make a difference by estimating individual risk and the chances of success for each patient.

1. Reasonable suspicion that the patient may suffer from prostate cancer

Based on clinical data (elevated PSA, suspicious digital rectal examination, family history of prostate cancer or suspicious results in new diagnostic tests, 4KScore, Phi-Index, etc. .).

2. Performing the multi parametric magnetic resonance (FOCALYX® Dx) after a consultation with the urologist

If suspicious injury or injury is detected in this study, the patient should be provided with an Echo MRI image fusion guided prostate biopsy (FOCALYX® Bx).

3. Planning the procedure

Our urologist / radiologist team evaluates the images and identifies the area of interest or suspect tumor area. Through a computer system – fusion software – the silhouettes are overlapped (magnetic resonance and ultrasound). A special software  is necessary  to recognize both types of images, assign “coordinates” for each type, combine and register the images, coordinate by coordinate. This is known as image registration and overlaps the sonographic image obtained “directly” to the static MR previously obtained image.  The result is a synthetic 3D image of the patient’s gland capable of locating GPS suspicious lesions with a variation of less than 2mm.

4. Perineal biopsy 

Under sedation, so that the patient does not suffer any discomfort, a perineal biopsy is performed of the suspicious areas, and / or of the different prostate anatomical regions, depending on each case.

5. Anatomopathological analysis

The tissue is sent for anatomopathological analysis and a few days later its result is known, to propose a treatment strategy, in agreement with the patient.
