Match each patient's clinical presentation with the single most appropriate initial or confirmatory imaging study to establish the diagnosis.
- A 72-year-old male presenting with fever, severe focal lumbar back pain, and recent onset of urinary incontinence.Magnetic resonance imaging (MRI) of the lumbar spine with and without intravenous contrast
- A 28-year-old male presenting with midline posterior neck tenderness and bilateral arm tingling after a high-speed rollover vehicular collision.Computed tomography (CT) of the cervical spine without intravenous contrast
- A 68-year-old female presenting with sudden onset of right-sided weakness, expressive aphasia, and a facial droop that began 45 minutes prior to arrival.Computed tomography (CT) of the head without intravenous contrast
- A 32-year-old female presenting with painful eye movements, blurred vision in one eye, and an afferent pupillary defect.Magnetic resonance imaging (MRI) of the brain and orbits with and without intravenous contrast
Cevap
Spinal epidural abscess requires MRI lumbar spine with contrast; acute cervical trauma requires noncontrast CT cervical spine; acute stroke (< 3 hours) requires noncontrast CT head; and optic neuritis requires MRI brain and orbits with contrast.
Each correct pairing directly aligns the clinical syndrome with the evidence-based imaging guidelines (ACR Appropriateness Criteria) balancing diagnostic sensitivity, time urgency, and therapeutic decision-making.
