[MRI/US-fusion for targeted prostate biopsy].
An innovative fusion of previously acquired magnetic resonance imaging (MRI) images with real-time transrectal ultrasound (US) may lead to improved prostate cancer detection, thus necessitating fewer biopsies. Suspicious lesions can be identified, localised - and possibly classified - via an MRI scan. Subsequently, a biopsy needle can be guided accurately into the suspicious area of the prostat...

متن کاملPrediagnostic Risk Assessment with Prostate MRI and MRI-Targeted Biopsy.
Prostate MRI is commonly used in the detection of prostate cancer to reduce the detection of clinically insignificant disease; maximize the detection of clinically significant cancer; and better assess disease size, grade, and location. The clinical utility of MRI seems to apply to men with no prior biopsy, who have had a previous negative biopsy, and men who are candidate for active surveillan...
متن کاملMRI guided prostate biopsy: The future for prostate cancer diagnosis?
Prostate cancer is the most common cancer in men, with a one in eight lifetime risk and 46,690 new cases diagnosed in the UK in 2014. Between 1979 and 2011 the incidence of prostate cancer in the UK has increased by 155%. The introduction of PSA testing and systematic transrectal ultrasound (TRUS) biopsies is responsible for a significant proportion of these new diagnoses. Over the same period ...
متن کاملNon-rigid MRI-TRUS registration in targeted prostate biopsy
A non-rigid registration method is presented for the alignment of pre-procedural magnetic resonance (MR) images with delineated suspicious regions to intra-procedural 3D transrectal ultrasound (TRUS) images in TRUSguided prostate biopsy. In the first step, 3D MR and TRUS images are aligned rigidly using six pairs of manually identified approximate matching points on the boundary of the prostate...
