Accuracy of single-voxel proton MR spectroscopy in distinguishing neoplastic from nonneoplastic brain lesions.
PURPOSE To measure the accuracy of single-voxel, image-guided proton MR spectroscopy in distinguishing normal from abnormal brain tissue and neoplastic from nonneoplastic brain disease. METHODS MR spectroscopy was performed at 0.5 T with the point-resolved spectroscopic pulse sequence and conventional postprocessing techniques. Subjects consisted of a consecutive series of patients with suspe...
متن کاملCan proton MR spectroscopic and perfusion imaging differentiate between neoplastic and nonneoplastic brain lesions in adults?
BACKGROUND AND PURPOSE Noninvasive diagnosis of brain lesions is important for the correct choice of treatment. Our aims were to investigate whether 1) proton MR spectroscopic imaging ((1)H-MRSI) can aid in differentiating between tumors and nonneoplastic brain lesions, and 2) perfusion MR imaging can improve the classification. MATERIALS AND METHODS We retrospectively examined 69 adults with...
متن کاملThe role of magnetic resonance spectroscopy in differentiation between neoplastic and non-neoplastic focal brain lesions
Keywords Focal brain lesions Magnetic Resonance Spectroscopy Neoplastic The ability to differentiate between neoplastic and non-neoplastic focal brain lesions is critical for appropriate management of patient. Due to low specificity of magnetic resonance imaging (MRI) adequate data for differentiating would not be provided. Magnetic resonance spectroscopy (MRS) is one of the newly supplementary...
متن کاملDifferentiation between brain tumor recurrence and radiation injury using perfusion, diffusion-weighted imaging and MR spectroscopy.
BACKGROUND Differentiation between tumor recurrence/vital tumor tissue and radionecrosis based on conventional diagnostic imaging is impossible because of the likeness of the images. In such circumstances advanced MRI techniques (PWI, DWI, 1HMRS) seem to be helpful. The aim of our study was to evaluate the diagnostic effectiveness of PWI, DWI and 1HMRS in the differentiation of the tumor recurr...
متن کاملDiscrimination between neoplastic and nonneoplastic brain lesions by use of proton MR spectroscopy: the limits of accuracy with a logistic regression model.
BACKGROUND AND PURPOSE The most accurate method of clinical MR spectroscopy (MRS) interpretation remains an open question. We sought to construct a logistic regression (LR) pattern recognition model for the discrimination of neoplastic from nonneoplastic brain lesions with MR imaging-guided single-voxel proton MRS data. We compared the LR sensitivity, specificity, and receiver operator characte...
