[Magnetic resonance imaging of brain neoplasms]

Area of Science:

• Neurology
• Radiology
• Medical Imaging

Background:

• Brain tumors are a significant health concern requiring accurate diagnostic tools.
• Magnetic resonance imaging (MRI) is a key modality for brain tumor detection.
• Evaluating the utility of low-field MRI in a large patient cohort is essential.

Purpose of the Study:

• To assess the diagnostic efficacy of low-field (0.04 T) magnetic resonance imaging (MRI) for detecting brain tumors.
• To analyze the types and characteristics of brain tumors identified using low-field MRI.
• To compare the diagnostic information provided by low-field MRI with higher-field systems.

Main Methods:

• Conducted a magnetic resonance (MR) study on 1035 patients with suspected brain tumors.
• Utilized a low-field imager operating at 0.04 Tesla.
• Analyzed MR features of detected tumors, including neuroepithelial tumors, meningiomas, hypophyseal adenomas, and metastases.

Main Results:

• Confirmed brain tumors in 593 out of 1035 patients.
• Identified neuroepithelial tumors, meningiomas, hypophyseal adenomas, and metastatic lesions as the most frequent findings.
• Demonstrated that low-field MR imaging can detect smaller tumors, localize them, and assess surrounding tissue status.

Conclusions:

• Low-field MR imaging provides valuable diagnostic information for brain tumors, comparable to high- and middle-field systems.
• This modality is effective in detecting tumors of smaller sizes and determining their dissemination.
• Low-field MRI aids in localizing tumors and evaluating the status of adjacent tissues, supporting clinical decision-making.
