Abstract

Procedure For Magnetic Resonance Spectroscopy Examination Technique In Brain Tumor Cases At The Radiology Installation Of Pertamina Central Hospital Jakarta. MR spectroscopy is one way of describing metabolites in tumor tissue without being invasive. Single spectroscopic approach, which is used in Magnetic Resonance Spectroscopy and is the most common spectral collection method in MRI modalities. MRi is the establishment of a medical diagnosis based on the principle of magnetic resonance. MRI aircraft produce images in various pieces namely coronal, sagittal, and transverse by not at all using x-rays that produce radiation and also using radioactive substances. Brain tumors are abnormally growing brain tissue cells originating from the brain or meningens, which are benign or malignant tumors that make massive pressure. MRS is a unique non-invasive sequence that helps in the identification of lesion molecules and the difference between malignant and benign lesions. In MRI examination of the brain with tumor cases there are several sequences used, namely Se / Fse Pd / T2, Se / Fse / incoherent spoiled, (DWI) diffusion weighted imaging (1) According to Elmaoglu (2), imaging techniques that can be used for MRI brain tumor cases include axial T1 spin echo, T2 fast recovery fast spin echo, T2 FLAIR, coronal T1 and T1 Axial post contrast injection, T1 coronal, and T1 sagittal, diffusion weighted imaging (DWI), magnetic resonance angiography, and magnetic resonance spectroscopy. In taking SVS LESION localizer must be precise on tumor tissue not taking part that is not part of the tumor, analyze tumor area and take SVS NORMAL localizer on other healthy tissue.

Abstract

Use Of Fat Saturation (FS) Sequences In MRI Knee Joint Examination Of Osteosarcoma Cases At Installation Radiology Hospital In Jakarta. Magnetic Resonance Imaging (MRI) is one of the medical support modalities used by doctors to diagnose a disease. MRI is capable of producing high resolution images of soft tissue and is capable of displaying various cuts (sagittal, axial, coronal and oblique) using high-strength magnetic fields and nuclei resonances of hydrogen atoms. Fat saturation is used to detect or extract signals from adipose tissue. Three methods can be used to achieve leanness: lean saturation, investment mulihan, and leaning phase. Fat sat is an umbrella term that encompasses several techniques, each with its own unique advantages, disadvantages, and strengths. During the MR imaging process, proton lipids and hydrogen protons from the air have different behaviors, and fat suppression techniques.The knee joint is a hinge joint with changes and is formed by both femoral condyles that are jointed with the superior surface of the tibia condyles. The patella is located above the smooth pateller surface of the femur and above that the patella slides as the joint moves. Osteosarcoma is a relatively common middle to high grade malignant soft tissue tumor, often with an early course affecting young patients, and most often involving soft tissue.
