The role T1-weighted fluid attenuated inversion recovery FLAIR) post contrast enhancement to improve image quality on MRI brain

. In general, head MRI examinations are performed using the T1-weighted and T2-
weighted sequence techniques. T1-weighted is used to see the anatomy of the brain while T2-
weighted aims to see the pathology or abnormalities that occur in the brain. Some of the clinics
that are often found in head MRI include tumors, meningitis, epilepsy, intracranial lesions,
metastases and others. The use of T1-weighted FLAIR sequences has a long duration of time,
but produces a good image and by adding contrast media can show more sensitive abnormalities
and minor abnormalities. The aim of the study was to analyze the application of the T1-weighted
FLAIR Contrast Enhancement sequence to be more informative than the T1-weighted Contrast
Enhancement sequence. This study uses the Systematic Literature Review (SLR) method. There
are 80 literatures that have been selected in the initial stage. It was then followed by an extraction
process, which produced 10 selected references. There are three stages of extraction, namely
looking at the abstract title, identifying inclusion criteria, and identifying exclusion criteria. The
results of this study indicate that the T1-weighted FLAIR Contrast Enhancement sequence is
more sensitive to minor lesion abnormalities such as clinical parenchymal lesions, meningitis
and leptomeningeal inflammatory disease than T1-weighted Contrast Enhancement.
