A CT scanogram of the lower limbs is a low‑dose CT‑based imaging technique that produces full‑length, straightened images of one or both legs for precise measurement of bone length and alignment. It uses CT scout or reconstructed projections to assess leg‑length discrepancy, deformities and mechanical axis deviations, aiding preoperative planning for orthopaedic procedures and evaluation of fractures or growth problems.

A scanogram (leg-length X‑ray) typically costs: in India about ₹300–₹2,000; in the US about $100–$600 privately; in the UK private clinics about £50–£200 (NHS patients usually receive it free). Prices vary by city, facility, and whether reporting/consultation is included, so check the specific hospital or imaging center for exact fees.

A CT scan of the left leg is a noninvasive imaging test that uses X‑rays and computer processing to produce detailed cross‑sectional images of bones, joints, muscles and blood vessels. It helps diagnose fractures, infections, tumors and vascular problems, guides surgical planning, and evaluates healing. Scans are quick, may use injected contrast for vessel detail, and involve small amounts of radiation.

A scanogram is a low-dose radiographic technique that accurately measures limb or bone lengths and detects leg-length discrepancies. By taking aligned images of the hip, knee and ankle, it minimizes magnification error and provides true bone measurements. It’s used to diagnose discrepancies, plan orthopedic procedures (osteotomy, limb-lengthening, joint replacement), fit prostheses, and monitor growth or treatment outcomes.

A CT scanogram (also called a topogram or scout) is a low-dose, full-length image acquired before the CT scan to localize anatomy and plan the scan range. It’s commonly used to measure limb length and detect leg-length discrepancy, assess spinal alignment (e.g., scoliosis) and guide surgical or radiation planning. It positions slices accurately and reduces unnecessary radiation.

Recovery after a scanogram is minimal. It's a quick X‑ray procedure—no anesthesia—and you can usually walk and resume normal activities immediately. You may feel mild discomfort from standing during imaging, but there’s no recovery time or wound care. No special aftercare is needed; follow any brief instructions if contrast or sedation were used. Radiation exposure is low.
