Abstract: In this research, 42 individuals with focal liver lesions were studied to see how well magnetic resonance imaging (MRI) characterized and diagnosed these conditions. Using diffusion-weighted imaging (DWI), dynamic gadolinium-enhanced sequences, and unenhanced MRI, we examined MRI signal intensity fluctuations affected by lesion histopathology and intracellular substances. The majority of the participants were middle-aged men (68% of the total), and the majority of the lesions were situated in the right lobe of the liver (61% of the total). Hemangiomas, metastases, hepatocellular carcinoma, and cholangiocarcinoma were among the 18 malignant lesions; abscesses, simple cysts, hydatid cysts, and hemangiomas made up the 24 benign lesions. With the exception of a few instances involving metastasis and hepatocellular carcinoma, radiological diagnosis and histological confirmation were quite concordant, with a success rate of 100% for benign lesions and 80-100% for malignant lesions. By accurately identifying benign cysts, hemangiomas, localized nodular hyperplasia, and metastases, MRI was able to anticipate the diagnosis in 90% of malignancies. The research emphasizes the use of magnetic resonance imaging (MRI) as a non-invasive diagnostic tool for liver lesions. Lesion characterisation is done precisely using MRI sequences that include pre-contrast T1 weighted, T2 weighted, in-phase and out-of-phase imaging, echo planar imaging (EPI)-DWI, and gadolinium-enhanced T1 weighted. Clinical decision-making and treatment planning for localized liver lesions are much enhanced by MRI, according to these data.
