Brain MRI & Advanced Neuroimaging
Standard brain imaging misses what matters most. Our NeuroCognitive MRI protocol and FDG-PET brain metabolism evaluation reveal the structural and functional findings that routine scans overlook—interpreted by a neurologist who knows what to look for.
What Standard Brain Imaging Misses
Most outpatient brain MRIs are designed to answer one question: is there a tumor, a bleed, or a large stroke? The scan runs three or four basic sequences, a radiologist reads it against a checklist, and the report comes back “unremarkable.” For the patient sitting in their doctor’s office with progressive memory loss, worsening brain fog, or persistent post-concussive symptoms, that word is not reassuring. It means the scan was not designed to find what is wrong with them.
The problem is twofold. First, protocol selection determines what pathology can be detected. Standard outpatient MRI protocols omit the sequences needed to evaluate white matter connectivity, hippocampal subfield volumes, or microhemorrhages from prior traumatic injuries. Diffusion tensor imaging, which maps the integrity of white matter tracts connecting cortical regions, is rarely included in outpatient protocols despite being one of the most sensitive markers for post-concussive injury and early neurodegeneration. Shenton et al. (2012, Brain Imaging and Behavior) demonstrated that DTI detects white matter abnormalities in mild traumatic brain injury patients whose conventional MRI appeared entirely normal.
Second, interpretation matters as much as acquisition. A scan is only as useful as the physician reading it. General radiologists may read hundreds of body scans per week—the brain is one organ among many, not the center of their practice. Subtle hippocampal asymmetry, early cortical thinning in a pattern consistent with frontotemporal degeneration, or scattered white matter lesions that suggest cerebral small vessel disease rather than benign age-related change—these findings require a reader who evaluates brain imaging in the context of a neurological examination and clinical history, not in isolation from a PACS workstation.
At The Neurogenesis Project, Dr. Orr reviews every brain image personally. He correlates imaging findings with the patient’s neurological examination, cognitive testing, and metabolic lab results. A white matter lesion is not simply “noted”—it is evaluated in the context of the patient’s vascular risk factors, symptom trajectory, and functional status. This is what separates diagnostic imaging from screening.
The NeuroCognitive MRI Protocol
Our NeuroCognitive protocol was designed specifically for patients whose clinical questions cannot be answered by standard imaging. It runs twelve to fifteen sequences depending on the clinical indication, including volumetric T1-weighted imaging for quantitative measurement of regional brain volumes, diffusion tensor imaging for white matter tract integrity, susceptibility-weighted imaging to detect microhemorrhages and hemosiderin deposits from prior head trauma, high-resolution coronal imaging of the hippocampal formations, and FLAIR sequences optimized for detecting subtle white matter disease.
Volumetric analysis compares your regional brain volumes against age-matched normative data. This is not a subjective assessment—it produces quantitative measurements of hippocampal volume, frontal lobe volume, temporal lobe volume, and other structures directly relevant to cognition and memory. Jack et al. (2010, Lancet Neurology) established that hippocampal volumetry is among the most reliable biomarkers for early Alzheimer’s disease, detecting atrophy years before clinical dementia criteria are met. A standard MRI cannot do this because it was not designed to.
For patients with a history of head trauma, our protocol includes susceptibility-weighted imaging that detects microbleeds invisible to conventional sequences. Toth et al. (2016, Journal of Neurotrauma) showed that traumatic microbleeds detected on SWI correlate with cognitive outcomes and are frequently present in patients whose conventional MRI was read as normal after a concussion. These findings change the clinical picture. They transform a diagnosis of “post-concussion syndrome” from a subjective label into an objective, documented brain injury.
When Brain Imaging Is Indicated
Not every patient needs a brain MRI or PET scan, and we do not order imaging without a clinical rationale. Dr. Orr evaluates each patient’s history, neurological examination, and cognitive testing to determine whether imaging will meaningfully change the diagnosis or treatment plan. Imaging is a diagnostic tool, not a screening product.
Brain MRI is typically indicated for patients presenting with progressive cognitive decline, memory loss out of proportion to age, persistent post-concussive symptoms beyond three months, new or changing headache patterns, focal neurological deficits, seizures, or symptoms suggesting a structural lesion. It is also indicated when prior standard imaging returned “normal” results in a patient whose clinical picture clearly suggests pathology.
Brain PET with FDG is indicated when structural MRI does not adequately explain the patient’s symptoms, when early neurodegenerative disease is suspected, or when the pattern of cognitive decline suggests a specific dementia subtype that requires metabolic confirmation. Dr. Orr discusses the rationale for each study before it is ordered, including what it can and cannot reveal, so that imaging decisions are informed and purposeful.
Our Imaging Modalities
Each modality answers a different clinical question. The appropriate study is determined by your neurological evaluation, not applied uniformly.
NeuroCognitive Brain MRI
Twelve to fifteen advanced sequences including volumetric analysis, diffusion tensor imaging, SWI for microhemorrhages, and high-resolution hippocampal imaging. Quantitative regional volume comparison against normative data.
$900
Brain PET/CT with FDG
Maps glucose metabolism across all brain regions, identifying areas of hypometabolism that indicate functional impairment invisible to structural MRI. Essential for Alzheimer’s evaluation, dementia differentiation, and seizure localization.
$1,750
Diffusion Tensor Imaging
Maps the structural integrity of white matter tracts that connect cortical regions. The most sensitive MRI technique for detecting post-concussive axonal injury and early connectivity disruptions in neurodegenerative disease.
Included in NeuroCognitive MRI
Volumetric Analysis
Quantitative measurement of hippocampal, frontal, temporal, and parietal lobe volumes compared to age-matched normative databases. Detects regional atrophy with statistical precision rather than subjective visual assessment.
Included in NeuroCognitive MRI
SWI Microhemorrhage Detection
Susceptibility-weighted imaging detects hemosiderin deposits from prior microbleeds that conventional MRI sequences cannot visualize. Particularly valuable for documenting traumatic brain injury and cerebral amyloid angiopathy.

Brain Health Lab Panels
Comprehensive metabolic, inflammatory, and hormonal panels that complement imaging by evaluating the biochemical environment your brain is operating in. Often ordered alongside imaging for a complete diagnostic picture.

Brain PET Scan
FDG-PET maps glucose metabolism across brain regions, revealing functional deficits that structural MRI cannot detect. Used for Alzheimer’s evaluation, dementia differentiation, seizure localization, and tumor grading.
Brain Health Lab Panels
Metabolic, inflammatory, and hormonal blood work that evaluates the biochemical environment your brain is functioning in. Often reveals treatable causes of cognitive symptoms that imaging alone cannot identify.
Alzheimer’s Prevention
Advanced imaging is a cornerstone of Alzheimer’s risk assessment. Volumetric MRI and FDG-PET can identify early neurodegenerative changes years before clinical symptoms meet diagnostic criteria, enabling earlier intervention.

If a standard MRI came back “normal” but your symptoms are real, the scan may not have been designed to find what is wrong. Dr. Orr’s advanced neuroimaging protocol is built for the clinical questions that standard imaging cannot answer.
