Proton MR spectroscopy improves discrimination between tumor and pseudotumoral lesion in solid brain masses.
BACKGROUND AND PURPOSE Differentiating between tumors and pseudotumoral lesions by conventional MR imaging may be a challenging question. This study aims to evaluate the potential usefulness and the added value that single-voxel proton MR spectroscopy could provide on this discrimination. MATERIALS AND METHODS A total of 84 solid brain lesions were retrospectively included in the study (68 gl...
متن کاملBrain abscess and necrotic brain tumor: discrimination with proton MR spectroscopy and diffusion-weighted imaging.
BACKGROUND AND PURPOSE Discriminating pyogenic brain abscesses from cystic or necrotic tumors is sometimes difficult with CT or MR imaging. We compared findings of proton MR spectroscopy ((1)H-MRS) with those of diffusion-weighted imaging to determine which technique was more effective for this differential diagnosis. METHODS Fourteen patients (necrotic or cystic tumor [n = 7]; pyogenic absce...
متن کاملProton Mr Spectroscopy in Brain Metabolic Disorders
Metabolic disorders of the central nervous system (CNS) include pathologies with extremely different pathogenesis. The clinical diagnosis of these disorders is often very difficult and requires sophisticated laboratory investigations. Proton magnetic resonance (MR) spectroscopy (1H-MRS) has been recently used in a number of clinical studies to supplement conventional MRI as it is able to provid...
متن کاملRole of diffusion-weighted imaging and proton MR spectroscopy in distinguishing between pyogenic brain abscess and necrotic brain tumor.
Brain abscesses and brain tumors may have similar clinical presentations. For example, only 50% brain abscess patients have fever, which could be masked by corticosteroid therapy. Also, the differential diagnosis of brain abscesses versus cystic or necrotic tumors may be difficult based on computed tomography (CT) or magnetic resonance (MR) imaging findings. However, the strategies of managemen...
متن کاملProton MR spectroscopy of brain abscesses.
We read with great interest the article by Pal et al. The authors reported on their experience with the application of proton MR (HMR) spectroscopy in the imaging evaluation of patients harboring intracranial abscess. In their retrospective study, they examined 194 patient charts and imaging studies, and they concluded that the detection of cytosolic amino acids is a strong indication of an abs...
