Magnetic Resonance Spectroscopic Imaging (MRSI) is an essential tool for quantifying metabolites in the body, but low spatial resolution limits its clinical applications. Deep learning-based super-resolution methods provided promising results improving of MRSI, super-resolved images are often blurry compared to experimentally-acquired high-resolution images. Attempts have been made with generat...

introduction: recently, magnetic resonance spectroscopic imaging (mrsi), as a functional imaging method, has been used for clinical target volume definition. in this study, we used this method to define the target volume in prostate radiotherapy. material and method: in this study, we used images of 20 prostate cancer cases. mrsi and mri images were fused with ct images. then, treatment plannin...

OBJECTIVE Anecdotal reports have suggested mood improvement in patients with bipolar disorder immediately after they underwent an echo-planar magnetic resonance spectroscopic imaging (EP-MRSI) procedure that can be performed within clinical MR system limits. This study evaluated possible mood improvement associated with this procedure. METHOD The mood states of subjects in an ongoing EP-MRSI ...

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...

MR spectroscopic imaging (MRSI) has become a valuable tool for quantifying metabolic abnormalities in human brain, prostate, breast and other organs. It is used in routine clinical imaging, particularly for cancer assessment, and in clinical research applications. This article describes basic principles of commonly used MRSI data acquisition and analysis methods and their impact on clinical app...

OBJECTIVE To design new models that combine clinical variables and biopsy data with magnetic resonance imaging (MRI) and MR spectroscopic imaging (MRSI) data, and assess their value in predicting the probability of insignificant prostate cancer. PATIENTS AND METHODS In all, 220 patients (cT stage T1c or T2a, prostate-specific antigen level <20 ng/mL, biopsy Gleason score 6) had MRI/MRSI befor...

BACKGROUND Integrated PET/MRI with hyperpolarized (13)C magnetic resonance spectroscopic imaging ((13)C-MRSI) offers simultaneous, dual-modality metabolic imaging. A prerequisite for the use of simultaneous imaging is the absence of interference between the two modalities. This has been documented for a clinical whole-body system using simultaneous (1)H-MRI and PET but never for (13)C-MRSI and ...
