Book your X-ray Scanogram at Molecular Diagnostics and Therapy, an NABL & NABH-accredited diagnostic centre. The X-ray Scanogram can be a special and particular type of radiograph that can help determine the lower leg length and the difference between the right and left leg lengths. The examination may be recommended if there is a difference in the length of the patient's legs, their walking problem, unequal leg length, or the length of the patient's legs is required to properly diagnose or plan treatment for orthopedic problems.

About X-Ray Scanogram

Imaging technology with radiography to evaluate lower limb length is called an X-ray Scanogram. It enables the doctor to make comparisons between the lengths of the right and left legs, and is used to evaluate certain differences in bone length. In general, the femur and tibia are scanned, depending on the type of scan. It may also be helpful in patients with suspected discrepancies in length, congenital and acquired bone abnormalities, history of fracture, or orthopedic abnormalities that impact upon leg alignment. Measurement of the length of all the long bones is useful for the assessment of a child's growth trajectory, for treatment planning in children, and for internal inspection prior to certain orthopaedic surgeries.

What is X-Ray Scanogram?

X-ray of a certain set of points on the lower limbs (known as a scanogram) is captured; finding the bone length and comparing the two lower limbs can aid in diagnosis on an X-ray. Measurements can be broken into two categories: one set of measurements using images, another using a special gadget that is placed in to collect long-length images. This test can also be valuable in determining if the difference in leg length is due to a short femur or a long tibia or both. It may also provide details of any selected alignment abnormalities in the right imaging modality.

Common Reasons for X-Ray Scanogram

• Unequal leg lengths: Measurement of differences between the right and left lower limbs.
• Limping or walking difficulties: Investigation of a possible limb-length discrepancy when clinically suspected.
• Orthopedic assessment: Evaluation before selected treatments or corrective procedures.
• Growth-related concerns: Monitoring limb length in children with conditions that may affect bone growth.
• Previous fractures: Assessment of possible differences in bone length following an injury.
• Congenital limb abnormalities: Measurement of limb length in patients with developmental differences.
• Bone growth disturbances: Evaluation of selected conditions that may affect normal growth of the femur or tibia.
• Joint replacement planning: Support for selected preoperative orthopedic measurements.
• Postoperative assessment: Review of limb length following certain orthopedic procedures when requested by the treating doctor.
• Treatment monitoring: Comparison of limb-length measurements over time when clinically indicated.

Conditions Evaluated

Limb-Length Discrepancy

Measuring the length of both lower limbs with the X-ray Scanogram is effective, and it is also possible to measure the length of both limbs and compare them using the scanogram. The degree of the difference may help the doctor decide whether to return to the original treatment or to leave it as is for the time being, in which case further evaluation or treatment may be required.

Femoral and Tibial Length Differences

When the imaging protocol and type of measurement remain the same, the exam might be of benefit to determine if the LLD is from the femur, the tibia, or both.

Congenital Limb-Length Differences

Scanogram may be used to assess limb-length differences associated with congenital conditions or developmental abnormalities affecting the lower limbs.

Growth-Related Bone Abnormalities

The clinician may repeat the assessments in case a condition or injury occurred that could have an impact if repeated, so that any progress of the leg bones can be observed.

Post-Traumatic Bone-Length Changes

When bones grow or heal as part of some kind of fracture or injury, the growth of the bones can produce a change in the length of the limbs. The treating clinician feels that it would be beneficial to apply measurements from the scanogram to assist in identification of those changes.

Orthopedic Alignment and Surgical Planning

When planning some orthopedic surgeries, the length of the limbs can be properly measured. If excessive motion or abnormal weight bearing is detected, further weight bearing and/or imaging might be necessary to comprehensively evaluate mechanical alignment.

Book Your X-Ray Scanogram

Visit to examination with all of your medical, X-ray, orthopedic, or scanogram records. Legible writing; tell the radiographer if you are possibly pregnant (the X-ray may not be done). Selected imaging technique (scanogram) setup and positioning should be in line with the orders of the imaging team at Molecular Diagnostics and Therapy.
