Radiomics and Prostate MRI: Current Role and Future Applications

2021

Multiparametric prostate magnetic resonance imaging (mpMRI) is widely used as a triage test for men at a risk of prostate cancer. However, the traditional role of mpMRI was confined to prostate cancer staging. Radiomics is the quantitative extraction and analysis of minable data from medical images; it is emerging as a promising tool to detect and categorize prostate lesions. In this paper we review the role of radiomics applied to prostate mpMRI in detection and localization of prostate cancer, prediction of Gleason score and PI-RADS classification, prediction of extracapsular extension and of biochemical recurrence. We also provide a future perspective of artificial intelligence (machine …

PERFORMANCE OF DIFFUSION KURTOSIS IMAGING FOR CHARACTERIZATION OF PROSTATE LESIONS USING 1.5T MAGNETIC RESONANCE IMAGING SCANNER

2020

The aim of the study is to evaluate the diagnostic performance of apparent diffusion coefficient (ADC) and apparent kurtosis coefficient (Kapp) for the characterization of prostate lesions on 1.5T MRI. This retrospective study included 34 patients with at least one lesion with PI-RADS score≥ 3. Performances of ADC and Kapp were evaluated using the Mann-Whitney U test and receiver operating characteristics curve (AUROC). Lesions with Gleason score≥6 had significantly lower Kapp compared to benign lesions (p=0.025). The ADC-ratio was the only significantly different parameter between GS≥7 and GS=6 lesions (p=0.039). Kapp showed the largest AUROC for the diagnosis of GS≥6 prostate cancers (AUR…

IS VISCERAL ADIPOSITY INDEX (VAI)RELATED TO PROSTATE CANCER DETECTED BY BIOPSY?

2014

association between obesity and prostate cancer, yielding inconsistent results. Metabolic syndrome has been suggested to promote aggressive prostate tumors. In a previous study we failed to detect a relation between Body Mass Index (BMI) and prostate cancer Gleason score (1). BMI, although routinely adopted to measure obesity, has low sensitivity and specificity. A novel sex-specific obesity index, based on waist circumference (WC), BMI, triglycerides (TGs) and high density lipoproteins (HDL), the Visceral Adiposity Index (VAI), has been proposed to estimate the visceral adiposity dysfunction (2). The aim of our preliminary research was to correlate VAI and BMI with the presence of prostate…
