Utilization of magnetic resonance imaging and magnetic resonance spectroscopy to evaluate cystic brain lesions

Abstract

Background: Cystic brain lesions may be exceedingly challenging to diagnose for both the radiologist and the neurologist. A biopsy or surgical approach followed by a histopathology study can pinpoint the exact final diagnosis in uncertain situations. Aims and Objectives: In the current study, magnetic resonance spectroscopy (MRS) and diffusion-weighted imaging (DWI) are being investigated as diagnostic modalities. Materials and Method: Cystic brain lesions from 78 participants were assessed by magnetic resonance imaging (MRI) and MRS. TI-weighted image (T1WI), T2-weighted image (T2WI), DWI, apparent diffusion coefficient (ADC), C+, and MRS imaging sequences are the parameters examined. Results: Pediatric group made up 29.5% of the entire population. The majority of the subjects (47.4%) had arachnoid cysts. About 79.5% of the individuals had hypointense T1WI, 100% had hyperintense T2WI, 82.1% had hypointense DWI, and 82.1% had high ADC. Arachnoid cysts contained lactate in 16.2% of the participants.Lipid was detected only in tumor lesions. Lactate with amino acid was observed in the abscess. Conclusion: Due to their noninvasive nature and low cost, DWI and MRS can be used as an adjunct to MRI, to improve the diagnosis of brain lesions.
