In a 2015 articles in the Journal of Urology, Thompson reported multi-parametric MRI detection of significant prostate cancer had sensitivity of 96%, specificity of 36%, negative predictive value and positive predictive values of 92% and 52%; when PI-RADS was incorporated into a multivariate analysis (PSA, digital rectal exam, prostate volume ...
To try and overcome current capacity issues with MRIs for prostate cancer, they have now set up the PRIME trial to explore whether a shorter and cheaper MRI scan could become the new standard of care.
These “hot spots” are then targeted using MRI fusion technology in which the MRI images are fused to the live ultrasound images during a prostate biopsy. The use of this imaging tool allows ...
Removing the final step – which involves patients being injected with contrast dye – could slash costs and time, as well an increasing availability.
The technique has demonstrated higher accuracy than other modalities in assessing seminal vesicle invasion and extra-capsular extension (ECE) of prostate cancer (96% and 81% respectively). Endorectal coil MRI is useful for determining the extent of spread and local invasion of cancers of the prostate, rectum, and anus. [2]
Correlation between biopsy and final pathology is improved between MRI-guided biopsy as compared to TRUS. [14] 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. Fusion MRI-US biopsies ...
