3D Proton MR Spectroscopic Imaging of Prostate Cancer: Accuracy Evaluation in Different Prostate Regions
نویسندگان
چکیده
Introduction/Purpose: The three dimensional magnetic resonance spectroscopic imaging (3D-MRSI) of prostate suffers from spatially dependent effects such as inhomogenous static magnetic field, spectral contamination from lipids, inhomogenous sensitivity of endorectal coil and motion artifacts. As a result of it, spectral quality and accuracy of fitted (choline+creatine)/citrate (CC/C) ratios substantially vary within measured 3D-MRSI data set. Therefore we evaluated routine 3D-MRSI protocol in the patients suspicious for prostate cancer and compared the accuracy of this method between the different prostate regions and measurement resolutions. Moreover, metabolic-quality maps as an effective way to present 3D-MRSI results by combing metabolic and error information in one image [1] are also demonstrated.

Optimization of clinical target volume delineation using magnetic resonance spectroscopic imaging (MRSI) in 3D conformal radiotherapy of prostate cancer
Background: For the purpose of individual clinical target volume assessment in radiotherapy of prostate cancer, MRSI was used as a molecular imaging modality with MRI and CT images. Materials and Methods: The images of 20 prostate cancer patients were used in this study. The MR and MRSI images were registered with CT ones using non-rigid registration technique. The CT based planning (BP), CT/MR...

Magnetic resonance spectroscopic imaging (MRSI) detects alterations in major prostate metabolites, such as citrate (Cit), creatine (Cr), and choline (Ch). We evaluated the sensitivity and accuracy of three-dimensional MRSI of prostate using an endorectal compared to an external phased array "receive" coil on a 3T MRI scanner. Eighteen patients with prostate cancer (PCa) who underwent endorectal...
