Aims and objectives
The morphological verification of prostate cancer in certain cases presents a difficult diagnostic problem.Recently,
concern over the increasing risk of antibiotic-resistant infection has prompted a re-evaluation of patient preparation,
as well as the number and frequency of prostate biopsies . Several studies about different types ofMRI/US fusion via software-based image coregistration without requiring the MRI for prostate cancerdiagnostics and local treatment appeared...
Methods and materials
36 patients with suspected prostate cancer with no histological verification after multiply (from twice to sixfold) US-guided sextant or saturation biopsies were included in the study.
Multiparametric high-field (1.5T) MRI with a torso phased-array surface coil were performed and showed “suspicious” prostate focuses in all cases.
Simultaneoussensor based MRand real-time TRUS images formationswere performed ("Virtual Navigator" Esaote,
Italy; "Smart Fusion" Toshiba,
After high accuracy...
Use of MR/TRUS-Fusion technique ensured the verification of prostate cancer in 27 cases.
chronic prostatitis and PIN were revealed in 9 cases.
Application of MRI/TRUS-Fusion technology may be helpful for precise guidance of target core-needle biopsy in cases where prostate cancer is suspected,
but standard systematic biopsy technique was inefficient.Future studies will be needed to evaluatethe clinical implications of MR/TRUS targeted biopsy.
