In simple words: The doctor uses a CT scanner to take detailed pictures of your leg. First, they take pictures without dye, then they inject a special dye into your vein to take more pictures. This helps them see any broken bones or other problems in your leg.

This radiology procedure involves a computed tomography (CT) scan of the lower extremity. It includes an initial scan without contrast material, followed by further sections with contrast material.The procedure is used to diagnose fractures or diseases of the lower extremity. The physician positions the patient, supervises contrast administration, and captures and interprets the images to prepare a report.

Example 1: A patient presents to the emergency department with severe pain and swelling in their lower leg following a fall. A CT scan of the lower extremity without and with contrast is ordered to evaluate for a possible fracture., A patient with chronic leg pain and suspected osteomyelitis undergoes a CT scan of the lower extremity without and with contrast to assess the bone and surrounding tissues., A patient with a known soft tissue mass in their lower leg undergoes a CT scan of the lower extremity without and with contrast to evaluate the size and characteristics of the mass and its relationship to adjacent structures.

Documentation should include the reason for the scan, the areas imaged, the contrast used (if any), and the interpretation of the findings.
