Spinal Imaging

Modern neuroimaging has revolutionized the practice of neurology by allowing visualization and monitoring of evolving pathophysiologic processes. High-resolution magnetic resonance imaging (MRI) can now resolve structural abnormalities on a near-cellular level. Advances in functional imaging can assess the in vivo metabolic, vascular, and functional states of neuronal and glial populations in real time. Given the high density of data obtained from neuroimaging studies, it is essential for the clinician to take an active role in understanding the nature and significance of imaging abnormalities. This chapter reviews computed tomography and MRI techniques (including angiography and advanced sequences), specialized protocols for investigating specific diagnoses, risks associated with imaging, disease-specific imaging findings with general strategies for interpretation, and incidental findings and artifacts. Figures include computed tomography, T1- and T2-weighted signal intensity, diffusion-weighted magnetic resonance imaging, magnetic resonance spectroscopy, imaging in epilepsy and dementia, extra-axial versus intra-axial lesions, typical lesions of multiple sclerosis, spinal imaging, spinal pathology, vascular pathology, intracranial hemorrhage, and common imaging artifacts. Tables list Hounsfield units, patterns of enhancement from imaging, advanced techniques in imaging, magnetic resonance imaging sequences, and the evolution of cerebral infarction and intraparenchymal hemorrhage on magnetic resonance imaging. This review contains 12 figures, 6 tables, and 213 references.

Acute Back Pain

Abstract Background: Patients with acute low back pain frequently request diagnostic imaging, and clinicians feel pressure to acquiesce to such requests to sustain patient trust and satisfaction. Spinal imaging in patients with acute low back pain poses risks from diagnostic evaluation of false-positive findings, patient labeling and anxiety, and unnecessary treatment (including spinal surgery). Watchful waiting advice has been an effective strategy to reduce some low-value treatments, and some evidence suggests a watchful waiting approach would be acceptable to many patients requesting diagnostic tests. Methods: We will use key informant interviews of clinicians and focus groups with primary care patients to refine a theory-informed standardized patient-based intervention designed to teach clinicians how to advise watchful waiting when patients request low-value spinal imaging for low back pain. We will test the effectiveness of the intervention in a cluster randomized clinical trial. We will recruit 8-10 primary care and urgent care clinics (~55 clinicians) in Sacramento, CA; clinicians will be randomized 1:1 to intervention and control groups. Over a 3 to 6 month period, clinicians in the intervention group will receive 3 visits with standardized patient instructors (SPIs) portraying patients with acute back pain; SPIs will instruct clinicians in a three-step model emphasizing establishing trust, empathic communication, and negotiation of a watchful waiting approach. Control physicians will receive no intervention. The primary outcome is the post-intervention rate of spinal imaging among actual patients with acute back pain seen by the clinicians adjusted for rate of imaging during a baseline period. Secondary outcomes are: use of targeted communication techniques during a follow-up visit with an SP; clinician self-reported use of watchful waiting with actual low back pain patients; post-intervention rates of diagnostic imaging for other musculoskeletal pain syndromes (to test for generalization of intervention effects beyond back pain); and patient trust and satisfaction with physicians. Discussion: This trial will determine whether standardized patient instructors can help clinicians develop skill in negotiating a watchful waiting approach with patients with acute low back pain, thereby reducing rates of low-value spinal imaging. The trial will also examine the possibility that intervention effects generalize to other diagnostic tests. Trial registration: NCT 04255199, ClinicalTrials.gov (January 20, 2020)

We report a case of a patient who presented complaining of a 1-week history of progressive lower limb weakness and decreased sensation bilaterally suggestive of a peripheral neuropathy, with vague associated symptoms of fluctuating concentration. Clinically, we suspected a Guillain-Barré variant. However, her functioning continued to decline despite intravenous immunoglobulin therapy, and she had normal spinal imaging studies and CSF analysis. Of note, she had a subtotal oesophagectomy and proximal gastrectomy 20 months previously for oesophageal cancer. We found her to be deficient in vitamin D, vitamin E and copper. She was treated with nutritional supplementation of these vitamins and infusion of trace elements, resulting in a gradual improvement in lower limb power, sensation and coordination, as well as improved cognition and mentation. Monthly outpatient neurology follow-up shows continued improvement in symptoms and return towards baseline functioning with regular infusions of nutritional elements and monitoring of blood levels.
