Influence of selecting EPI readout-encoding bandwidths on arterial spin labeling perfusion MRI.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Although N2 ghosting can be reduced by adjusting the bandwidth of EPI on the time-series of PWI data, the effects cannot be entirely eliminated. In particular, N2 ghosting can bias CBF quantification if EPI control scans to determine the equilibrium-state signal are confounded by N2 ghosting. Therefore, careful tuning of the bandwidth of EPI is necessary to avoid artifacts in the ASL signal from N2-ghosting. PMID: 19578915 [PubMed - as supplied by publisher] (Source: Magma)

Proton magnetic resonance spectroscopy of the central, transition and peripheral zones of the prostate: assignments and correlation with histopathology.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Proton magnetic resonance spectroscopy (MRS) is used to compare the chemistry of the transition, central and peripheral zones of the prostate. The assignments are made using two-dimensional correlated spectroscopy and the results compared with histopathology. The chemistry associated with benign prostatic hyperplasia (BPH), prostate intraepithelial neoplasia (PIN) and malignant biopsy tissues are described. There are distinct MR spectral patterns for glandular and stromal BPH, PIN and adenocarcinoma. Importantly, there are also different spectral patterns from BPH in the transitional and central zones when compared to ...

The role of endorectal coil MRI in preoperative staging and decision-making for the treatment of clinically localized prostate cancer.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSION: eMRI allows for more accurate local staging by complementing the existing clinical variables through improvements in spatial characterization of the prostatic zonal anatomy and molecular changes. These improvements in tumor staging enhance our ability to individualize treatment selection and tailor the approach to maximize cancer control while minimizing treatment related morbidity.
