MRI Brain Angio+Spectroscopy Hyderabad | Focus Diagnostics

MRI Brain Angio + Spectroscopy Scan in Hyderabad

The MRI Brain Angio + Spectroscopy protocol at Focus Diagnostics is a dual-purpose diagnostic scan that pairs Magnetic Resonance Angiography (MRA) with Magnetic Resonance Spectroscopy (MRS). While MRA produces high-resolution, three-dimensional views of the intracranial arteries and venous structures without requiring arterial catheterization, MRS provides a non-invasive "chemical biopsy" by quantifying brain metabolites such as NAA, Choline, Creatine, and Lactate/Lipid peaks. This combined protocol allows clinicians to evaluate both vascular compromise and metabolic alterations within brain tissue in a single session.

Why Is an MRI Brain Angio + Spectroscopy Performed?

• Brain Tumor Grading & Characterization: Differentiating high-grade gliomas from low-grade tumors, lymphoma, or brain metastases based on elevated Choline-to-NAA ratios and vascularity.
• Tumor Recurrence vs. Radiation Necrosis: Distinguishing viable recurrent tumor growth from radiation-induced tissue damage following radiotherapy.
• Cerebrovascular Disease & Stroke Risk: Detecting intracranial aneurysms, arteriovenous malformations (AVMs), arterial stenoses, arterial dissections, and vascular occlusions.
• Infectious & Inflammatory Lesions: Differentiating brain abscesses, tuberculomas, and neurocysticercosis from neoplastic lesions by identifying specific amino acid and acetate resonance peaks.
• Metabolic & Neurodegenerative Disorders: Evaluating neurodegenerative disorders, mitochondrial encephalopathies, and hypoxic-ischemic encephalopathy via lactate accumulation and neuronal loss markers.

Key Benefits at Focus Diagnostics Hyderabad

• Dual Structural & Metabolic Assessment: Integrates 3D Time-of-Flight (TOF) vascular imaging with single-voxel or multi-voxel proton spectroscopy.
• Non-Invasive Vascular Visualization: Clear arterial mapping performed routinely without catheter insertion.
• Subspecialty Neuroradiology Review: Formatted metabolite curve interpretations and vascular reconstructions analyzed by experienced radiologists.

Patient Preparation and Important Instructions

• Fasting: Routine non-contrast protocols do not require fasting; however, 4 to 6 hours of fasting is recommended if IV contrast is prescribed.
• Motion Restriction: The MRS component requires strict stillness, as head movement can degrade spectral resolution and baseline baseline phase correction.
• Safety Clearance: Remove all metallic objects, jewelry, watches, hair accessories, and dentures before entering the MRI room.
• Implant Verification: Inform the technical staff if you have cardiac pacemakers, neurostimulators, cochlear implants, or cerebral aneurysm clips.
