In TRUS multiparametrisk mr prostata, the clinician typically performs a sextant biopsy, systematically sampling the base, middle, and apex of each hemigland 3. Despite being long considered the gold standard for diagnosis, TRUS biopsy has several shortcomings. Because ultrasound usually fails to visualize cancer, a TRUS biopsy is performed by systematically sampling all parts of the prostate, rather than aiming at individual targets Figure 1. Prostate magnetic resonance imaging MRIreported as early ashas revolutionized prostate cancer diagnosis during the past decade 6.

This combined multiparametric imaging modality facilitates tumor multiparametrisk mr prostata and has been shown to have superior ability to detect prostate cancer. ROIs are graded on a five-point Likert scale, where a score of 1 has multiparametrisk mr prostata low risk of malignancy and a score of 5 is considered a high-risk lesion.

ROIs classified as Grade 3 or above are often pursued during prostate biopsy. In this modality, a software platform overlays mpMRI data onto live transrectal ultrasound images and creates a fused three-dimensional 3D model, enabling the operator to visualize an MRI-detected ROI in real time on a monitor. These ROIs may then be individually targeted, known as the Prostatite cronica biopsy".

The trajectory of each needle and biopsy core location are tracked with a high degree of accuracy and registered within multiparametrisk mr prostata software system Figure 2.

This allows the clinician to resample a target within 3 mm at any follow-up biopsy session 13 Biopsy tracking is particularly useful in active prostatite programs in that foci of Prostatite cronica cancer may be reliably monitored for pathologic progression over multiparametrisk mr prostata.

With reduced detection of clinically insignificant cancer, guided biopsy can spare many patients the emotional distress of a cancer diagnosis as well as the morbidity multiparametrisk mr prostata with further prostate biopsies. Patients harboring intermediate or high-risk prostate cancer are likely to be diagnosed via guided biopsy and can be referred for treatment accordingly.

Several platforms have now been developed and are available internationally. Each uses proprietary software and hardware to merge MRI and US data in real time to enable targeted biopsy. Table 1 presents data for several of the most multiparametrisk mr prostata used fusion systems Performed in the clinic under local anesthesia, this new biopsy method is multiparametrisk mr prostata gaining adoption for the diagnosis and surveillance of prostate cancer.

All patients undergoing fusion biopsy have had mpMRI of the prostate, which has been interpreted by an experienced uro-radiologist who has read over 3, prostate MRIs.

Prior to the procedure, MRI images are uploaded to software for prostate and target contouring by the radiologist. All patients undergoing targeted biopsy also undergo systematic biopsy, guided by multiparametrisk mr prostata template generated by the fusion device software. If no discrete targets are seen on MRI, only software-guided systematic biopsy is performed. Patients with multiparametrisk mr prostata diathesis or inability to tolerate biopsy without sedation are considered ineligible.

NOTE: Contoured targets from the mpMRI as well as digital markers denoting a template for systematic biopsy are now superimposed onto the 3D prostate model created during the acquisition step.

Subjects underwent mpMRI of the prostate with a Trattiamo la prostatite Tesla magnet prior to biopsy. This system was used to obtain targeted cores from ROIs if present.

All patients multiparametrisk mr prostata a core systematic biopsy using a template generated by the fusion system regardless of whether targeted biopsy was performed. Multiparametrisk mr prostata sextants were sampled during systematic biopsy, including those that contained ROIs.

The biopsy strategies compared were targeted biopsy, systematic biopsy, and the simultaneous performance of both targeted and systematic biopsy within the same session, Prostatite as the "combination biopsy. Among all patients, patients had at least one ROI classified as grade 3 or higher.

For maximum ROI grade, patients had a grade 3 lesion, had a grade 4 lesion, and 89 had a grade 5 lesion. While cases of clinically significant disease were detected via combination biopsy, patients with clinically significant disease were identified using targeted biopsy alone and were identified with systematic biopsy alone. Of this group, 15 patients with high-risk disease would have otherwise been undiagnosed if only multiparametrisk mr prostata biopsy was performed.

Multiparametrisk mr prostata identification of clinically significant prostate cancer was directly related to ROI grade. Combination biopsy also outperformed both targeted biopsy and systematic biopsy for all grades of ROI Figure 4. Figure 1 : Transrectal ultrasound image of prostate.
