Home - Hamilton Health Care System. All the staff that helped us was wonderful.\u. One of the ladies who helped do personal care for my father and the nurse were the same that helped with my mother who passed away in 2. It was good to see them again.\u.

Non-Cardiac Indications: Aetna considers single photon emission computed tomography (SPECT) medically necessary for any of the following indications. So we speculate that our patient has occlusion of the origin of the right posterior inferior cerebellar artery, which probably gave rise to the bilateral medial.

Aetna considers magnetic resonance spectroscopy (MRS) (also known as NMR spectroscopy) medically necessary for distinguishing recurrent brain tumor from radiation necrosis. Aetna considers magnetic resonance spectroscopy (MRS) (also known as NMR spectroscopy) experimental and investigational for all other indicaitons, including the following (not an all- inclusive list) because there is a lack of evidence of its efficacy in the medical literature.

Background. Magnetic resonance spectroscopy (MRS), also known as nuclear magnetic resonance (NMR) spectroscopy, is a non- invasive analytical technique that has been used to study metabolic changes in brain tumors, strokes, seizure disorders, Alzheimer's disease, depression and other diseases affecting the brain. It has also been used to study the metabolism of other organs. Magnetic resonance spectroscopy can be done as part of a routine magnetic resonance imaging (MRI) on commercially available MRI instruments.  The probe accessory necessary to perform MRS was granted 5. Food and Drug Administration (FDA).  Magnetic resonance spectroscopy and MRI use different software to acquire and mathematically manipulate the signal.  Whereas MRI creates an image, MRS creates a graph or "spectrum" arraying the types and quantity of chemicals in the brain or other organs.

The role of MRS in diagnosis and therapeutic planning has not been established by adequate clinical studies.  Specifically, there have been no clinical trials demonstrating improved outcomes in patients evaluated with MRS compared to patients evaluated with conventional imaging modalities. Guidelines on central nervous system cancers from the National Comprehensive Cancer Network (NCCN, 2. Zhang, et al. (2. MRS) in differentiating glioma recurrence from radiation necrosis. Studies about evaluation of MRS for the differential diagnosis of glioma recurrence from radiation necrosis were systematically searched in Pub. Med, Embase and Chinese Biomedical databases up to May 4, 2.

The data were extracted to perform heterogeneity test, threshold effect test and to calculate sensitivity (SEN), specificity (SPE) and areas under summary receiver operating characteristic curve (SROC). Eighteen articles comprising a total sample size of 4. Quantitative synthesis of studies showed that the pooled SEN and SPE for Cho/Cr ratio were 0. CI: 0. 7. 7, 0. 8. CI: 0. 7. 4, 0. 9. The area under the curve (AUC) under the SROC was 0. The pooled SEN and SPE for Cho/NAA ratio were 0.

CI: 0. 8. 1, 0. 9. CI: 0. 7. 6, 0. 9. The AUC under the SROC was 0. The authors concluded that this meta- analysis shows that MRS alone has moderate diagnostic performance in differentiating glioma recurrence from radiation necrosis using metabolite ratios like Cho/Cr and Cho/NAA ratio. The authors strongly recommended that MRS should combine other advanced imaging technologies to improve diagnostic accuracy.

This authors states that this metaanalysis underlines the importance of implementing multimodal imaging trials and multicentre trials in the future. Chuang, et al. (2. MR perfusion and spectroscopy. Medline, Cochrane, EMBASE, and Google Scholar were searched for studies using perfusion MRI and/or MR spectroscopy published up to March 4, 2. Only two- armed, prospective or retrospective studies were included. A meta- analysis was performed on the difference in relative cerebral blood volume (r. CBV), ratios of choline/creatine (Cho/Cr) and/or choline/N- acetyl aspartate (Cho/NAA) between participants undergoing MRI evaluation.

A χ2- based test of homogeneity was performed using Cochran's Q statistic and I2. Of 3. 97 patients in 1. As there was evidence of heterogeneity among 1. CBV for evaluation (Q statistic = 3. I2 = 9. 7. 1. 1%, P < 0. The pooled difference in means (2.

CI = 0. 8. 5 to 3. CBV in a contrast- enhancing lesion was significantly higher in tumor recurrence compared with radiation injury (P = 0. Based on a fixed- effect model of analysis encompassing the six studies which used Cho/Cr ratios for evaluation (Q statistic = 8. I2 = 4. 0. 3. 9%, P = 0. CI = 0. 5. 7 to 0. Cho/Cr ratio was significantly higher in tumor recurrence than in tumor necrosis (P = 0.

There was significant difference in ratios of Cho to NAA between recurrent tumor and necrosis (1. CI = 0. 0. 3 to 2.
