Final answer:
A Cervical MRI is the best imaging study for a patient with acute cervical radiculopathy following a fall, as it provides detailed images of soft tissue and nerve structures.
Step-by-step explanation:
The most appropriate study for a patient who suffered a fall and presents with acute cervical radiculopathy is a Cervical MRI. This imaging modality is highly sensitive for detecting soft tissue injuries, including herniated discs and nerve root impingement, which are common causes of radiculopathy. A Cervical CT could provide details on bone injuries, and a lateral C-spine radiograph gives an initial assessment but may not show soft tissue and nerve details. A myelogram, which involves injecting contrast dye into the spinal canal, is usually not the first imaging study chosen due to its invasiveness and is typically reserved for cases where MRI is not available or is contraindicated.
