CT BILATERAL KNEE

Introduction 

CT of the Bilateral Knees (Computed Tomography) is an imaging method that considers both knee joints at the same time. It captures the anatomy of the bones, joints, and their relative positions in both cross-section and three-dimensional perspectives. CT scan possesses special value in estimating the presence of multifaceted fractures, evaluating surgical hardware, assessing congenital or degenerative changes, and planning orthopaedic surgeries. 

What is CT Bilateral Knee CT scan? 

This scan is carried out by x-ray emission focusing on both knees at the same time to obtain detailed images of the specific anatomy of interest. Data obtained is reconstructed to give axial, sagittal, and coronal views. The views can also be further operated on to yield 3-D images that display the bones and joints in their spatial relationships. 

• Analytical unit range regarding the test 
• Bone and joint condition 
• Joint space narrowing and cartilage condition 
• The presence of bone fractures or dislocations 
• Bone spurs, cysts or lytic lesions 
• Post-surgical implant evaluation (if necessary) 

• Investigating bilateral pain of the knee 
• Confirm or exclude the presence of fractures 
• Assess position for implant for prosthesis fixation 
• Joint degeneration of the knee and osteophytes 
• Post-operative monitoring 

When and Who Needs This Scan? 

Primary Symptoms 

• Pain or stiffness in both knees 
• Aryl or joint damage after an injury 
• Assessment before knee replacement surgery 
• Evaluation of Osteoarthritis 
• Assessment of congenital malformations or joint misalignment 

Image Region Scope 

• Most aged people suffering from Osteoarthritis 
• Sportsmen with stress injuries 
• Patients requiring bilateral knee surgery (post-trauma) 
• Pre-operative orthopaedic patients 
• Skeletally immature patients with abnormal growth 

Benefits of Taking the Test

• Enhanced imaging of bone detail 
• Evaluation of bilateral knees in one shot 
• Useful for surgical and rehabilitation strategizing 
• Quick, effective, and non-invasive diagnostic technique 

Conditions Diagnosed with Bilateral Knee CT

• Osteoarthritic bilateral knee fractures 
• Cartilaginous bone osteoarthritic lesions 
• Cystic lesions or bone tumours 
• Subluxation or dislocated joints 
• Congenital bone deformities 

• Report any allergies to contrast material 
• Notify the radiologist if any metal around the knees are present; otherwise, no fasting is required. 

Pre-requisite  

• Appointment from a medical doctor 
• Check for kidney function and allergies when using contrast 

Best Time to Take the Scan 

• To follow as prescribed in the referral 
• Morning bookings provide optimum efficiency. 

Eligibility 

• Low risk to most patients 
• Avoid during pregnancy unless it is medically needed. 

Procedure 

• Patient is positioned on the CT table, arms adducted, and head tilted towards midline 
• Position the legs to include both knees in the scan range 
• Scanning occurs over a period of 5-10 minutes 
• Image data is utilized to generate three-dimensional (3D) reconstructions 
• In case soft tissue or vascular detail is needed, contrast can be injected. 

Caution 

• Do not lean forward or backwards during the scan. 
• Inform the technician beforehand regarding any metal or surgical implants placed around the knees.
