MRI-targeted prostate biopsy : the limitations of MRI-TRUS image fusion

Hamid et al, from the well-known UCL (University College London) (1), present the results of their own image fusion software (SmartTarget) used to perform MRI-targeted prostate biopsies. The software is a deformable (or elastic) fusion system, therefore not using real-time navigation. Three samples were taken from 129 patients with a Likert score 3, 4 or Read more…

To what extent can the existence of significant prostate cancer be ruled out in case of a non-suspicious MRI ?

To answer this question, Panebianco et al (1) followed-up 1255 patients with a non-suspicious MRI (PI-RADS score <3) for 4 years. Follow-up included PSA assay, multiparametric MRI (T2W, DWI and DCE) and systematic biopsies whenever deemed necessary, mainly when PSA level increased and/or PSA density (PSA level/prostatic volume) >0.15. Tumor significance was defined by systematic biopsies Read more…

Positive pre-biopsy MRI : are systematic biopsies still useful in addition to targeted biopsies ?

Ploussard et al (1) answered positively in a recent review with the argument that systematic biopsies (SB), in addition to targeted biopsies (TB), improved the detection rate of significant cancers (defined by the presence of Gleason 4 grade) by about 10%. The assumed reasons to explain this 10% gain are 1-the far lateral location of Read more…

Prostatic MRI before biopsy : a point of no way back

The PRECISION trial The debate on to do or not to do a prostate MRI before biopsy is probably over. The PRECISION trial (1) is a multicenter study (25 centers, 11 countries) of 500 naïve biopsy men suspected of prostate cancer. All had a pre-biopsy MRI, performed by expert radiologists in each center. In case Read more…
