 Hello, everybody. This is Dr. Hashna Subramaniam from Mahatma Gandhi Medical College and Research Institute for the Cherry. My paper topic is role of 1.5 Tesla Magnetic Respiratory Spectroscopy and intramural spinal lesions. A spectrum of diagnosing concentrations may affect the spinal cord, which includes developmental anomalies, inflammation, infectious processes, as well as degenerative conditions, as well as benign and melancholy of lassobs. Patients with intramural spinal cord lesions commonly present with tickling pain, numbness and weakness. MRI is the current imaging model of choice in the evaluation of patients present with myelopathy symptoms in the surface spinal cord lesions. It is important to recognize and differentiate non-neoplastic from neoplastic process spinal cord as the two entities' differentiation is extremely crucial to the neurosurgery. MRS is a non-invasive tool which helps to characterize the chemical composition of human tissue. However, it can help to better characterize pathological process affected in the spinal cord and also help to provide important clinical markers for differential diagnosis. Ames and objectives are the purpose of the study is to determine the role of 1.5 MRS in evaluation of patients with intramural spinal cord lesions to enable reliable metabolite concentration and the quality of the system pathological. Inclusion criteria is patients with intramural spinal cord lesions, exclusion criteria are patients with recurrent lesions, previously operated lesions and contraindications for MRS like pacemaker cochlear impact and unconsenting and uncooperative patients. Materials and methods, the study was carried out on 30 patients with intramural spinal lesions for a period of one year from June 2021 to June 2022. Return informed consent was obtained from each patient in the patient with the study group. Standard MRS spine and MR spectroscopy were done on 1.5 Tesla Phillips Achieva MRS scanner. The sequence lasts for about five minutes. This is the spinal MRS protocol. Single voxel MRS was applied either in T2 SAJ or post-contrast T1 SAJ, that's a prestige. Size of the voxel adjusted according to size of the lesion. MRS data were acquired post processing done to a good spectrum of metabolites. Integral values of metabolites in each spinal intramural spinal cord lesion were obtained. These patients were followed for the postoperative tissue and histopathological examination results to compare the MRS. The first cases, we'll now discuss the common spinal cord neoplasms. First case is intramidality of a cloma. 30-year-old male had history of numbness involving off volumes. T2 short, long segment intramidality, T2 SAJ short, long segment intramidality hyperintensity from C8 to D8 level. T1 FATSAT post-contrast short, intense homogenous enhancement from D4 to D8. MRS short reduced NLA and creatinine with increased lactate peak at 1.3 BPM. Biopsy came out to be tuberculosis etiology. Coming to the second case, epandymoma. 20-year-old female patient, present with the complaint of gradual onset of viral viruses, there were no history of fever. T2 short, hetero-intensive solidation with hyperintensity carriers causing cod expansion occupying the medulla and cervical dorsal region. T1 post-contrast short heterogeneously enhancing lesion at cervical medullary junction. MRS short decreased NAA, lactate was not very much increased and creatinine is increased. Biopsy came out to be low-grade glioma. Coming to the third case, astrocytoma. 30-year-old male had history of progressive weakness involving both upper limb. T2 short intramedullary T2 hyperintensity with cod expansion extending from C5 to C7 level. T1 post-contrast short subtile enhancement within the lesion. MRS short increased colon NAA decreased, creatinine was almost like 0. Biopsy came out to be glioblastoma features. Coming to the results, in tuberculoma, we have significant increase in lipid and lactate with decreased NAA, colon not significantly increased. In dermatitis, lipids mixed with lactate peak will be seen and lactates were also clearly observed at 1.3 ppm. In epandymoma, colon significantly increased, NAA decreased and lactate were not very much decreased. In three patients, we observed significant increase in creatinine peak at 3.9 ppm. In low-grade glioma, NAA decreased, lactate not very much increased, creatinine increased and colon was want to be increased. In GBM, colon increased, creatinine almost 0, NAA decreased. In multiple sclerosis and other intramural relations, significant reduction in NAA was observed. Conclusion, MR spectroscopy of the spinal cord is the valuable non-invasive tool for research and diagnosis because it can provide additional information which is complementary to other non-invasive imaging methods. It is also an emerging tool which adds us a new biomarker information to characterize the spinal cord tumors to differentiate benign and malignant lesions thereby helps to prevent unnecessary biopsies and surgeries. However, the application of MRS in the spinal cord is now straightforward and a great car is quite optimal spectral quality. Thank you.
