Prostate MR with the 3.0T Endo coil

Best Practice
Friel, Harry Philips Healthcare USA

The combination of the Achieva 3.0T MRI scanner and the 3.0T Endo coil is facilitating diagnosis, staging, pre-surgical or pre-radiation planning and follow up for patients who have had suspicious findings on PSA tests or biopsies. With more signal and more power, 3.0T MR imaging can help delineate areas of abnormality that can be used for targeted biopsies in men who have had standard sextant biopsies without conclusive findings. And MR spectroscopy at 3.0T provides unique functional data on molecular biomarkers in the prostate that typically indicate the presence of cancer.

Multi-parametric 3.0T MRI provides excellent prostate imaging

MR prostate imaging is becoming more widely used, and Philips is ahead of the curve with the development of a 3.0T solution for high quality, robust imaging of the prostate. The 3.0T Endo coil - a co-development of Philips and Medrad for use with Achieva 3.0T X-series - conforms to the shape and size of the prostate for reliable contact. The coil provides optimum signal-tonoise ratio, especially when combined with a multi-element coil such as the Philips 6-channel SENSE Cardiac coil.

Advanced imaging techniques such as 3D MR spectroscopy add to the specificity of prostate MR imaging. MR spectroscopy provides information about the chemical balance within the prostate by showing levels of certain indicative metabolites such as choline, polyamines and citrate. In healthy prostate tissue, citrate and polyamine levels are high and choline levels are low. In tumors, the ratio is inverted. Spectroscopy thus helps to distinguish between healthy and abnormal prostate tissue by virtue of its ability to determine these metabolite levels, and can support that a low signal intensity on a T2-weighted MR image is actually an abnormal lesion. These metabolite levels can also be tested after treatment, to check for a possible lesion recurrence.

 

Spectroscopy is a signal-to-noise limited technique, so at 3.0T, clinicians have access to smaller voxels than at 1.5T, which creates higher resolution spectroscopic images. After acquiring these images, Philips SpectroView provides simple, efficient processing and analysis of 3D spectroscopic datasets for improved workflow. SpectroView automatically delivers quantification of metabolites, with a clear display of the choline-to-citrate ratio.

 

Philips MR clinical scientist Harry Friel worked with several sites during development and integration of the Endo coil on the Achieva 3.0T. "The extraordinary signal of the 3.0T Endo coil enables high resolution T2-weighted, diffusion weighted, DCE and spectroscopic imaging."

 

Three different centers show that advances in imaging facilitate diagnosis, localization, staging of protstate lesions.
