CT - Scannogram

CT – Scannogram is a specialized imaging technique used as a preliminary or planning scan in computed tomography (CT). It provides a single, long image of a body part, often used to measure anatomical structures and guide further detailed CT imaging.

One of the most common uses of a scannogram is for accurate measurement of limb lengths, especially in cases of suspected limb length discrepancy. It can also be used for spine alignment assessment or pre-surgical planning.

Unlike standard CT scans that produce multiple cross-sectional images, a scannogram generates a projection image similar to an X-ray but with enhanced precision and measurement capabilities.

This scan is quick, non-invasive, and involves minimal radiation exposure. It plays an important role in orthopedic evaluation, treatment planning, and ensuring accurate positioning for further CT imaging.

This test is recommended for individuals requiring measurement or planning evaluation.

It is advised in the following cases:

• Suspected limb length discrepancy
• Orthopedic assessment
• Pre-surgical planning
• Growth-related abnormalities
• Spine or bone alignment evaluation
• As a preliminary scan before detailed CT imaging
