3D CT PELVIS

Introduction 

A 3D CT (Computed Tomography) scan of the pelvis is an advanced diagnostic imaging method that renders the pelvic bones and surrounding structures with precise detail and in three-dimensional format. It is used mainly for evaluating complex fractures, assessing congenital abnormalities, for tumours, or for planning surgical procedures.  

What is a 3D CT Pelvis? 

This procedure employs beams of X-rays and specialized software to generate a series of cross-sectional images of the pelvis, which is later reconstructed into three-dimensional views for a complete analysis. It helps clinicians evaluate bony anatomies, identify structural anomalies, and plan appropriate interventions as needed. 

• Spinal column and pelvic bone alignment and symmetry  
• Hip joint spacing and surface integrity 
• Fracture presence and type 
• Sacroiliac joint condition 
• Presence of neoplasm, cysts, or degenerative changes  

• Evaluation for trauma and fractures of the pelvis  
• Inflammatory or infectious processes affecting bones as a condition  
• Ortho surgeries as a corrective procedure for post-operative implant position and inspect healing* Bone METs screening. 

When and Who Needs a 3D CT Pelvis?

Indications: 

• Pelvic trauma in a patient  
• Chronic pain in the hip or sacroiliac joint  
• Tumours or infections needing diagnostic imaging  
• Hip or complex reconstruction surgery requiring preoperative imaging  
• Assessment for congenital bone anomalies  

Patient Demographics: 

• Trauma patients with skeletal injuries from motor vehicle accidents or falls 
• Hip degenerative diseases in aging populations 
• Bone metastases in cancer patients 
• Congenital skeletal abnormalities in paediatrics  

Benefits of Taking the Test

• Precise identification with high resolution 3D visualization. 
• Accurate calculation of bone defects or abnormalities. 
• Non-invasive advanced 3D imaging is essential in complex surgical planning. 
• Non-surgical and rapid capturing of images. 

Conditions Diagnosed

• Pu-adductors and acetabulum-pubic rami fractures. 
• Acetabular or hip dislocation or hip dysplasia. 
• Osteogenic neoplasms and metastatic deposits. 
• Osteomyelitis (infection in the bones). 
• Ankylosing spondylitis with sacroiliitis. 

• Wearing loose-fitting, metal-less attire. 
• Mention any past surgical procedures or implants. 
• No prior fasting is required for non-contrast exams. 

Pre-requisites 

• Must have a referral from a health professional. 
• For contrast exams, allergic history and renal function screening must be done. 

Best Time to Take the Scan 

• According to clinical urgency or surgical calendar 
• Morning is preferred for efficient reporting turnaround. 

Eligibility 

• Generally safe for most patients. 
• Risk-free involves pregnancy and those allergic to contrast. 

Procedure 

• Patient assumes a supine position on the CT table. 
• The patient’s pelvis is centred and held in place. 
• Scanning lasts for a 5 to 10-minute duration. 
• Optional contrast injection is available. 
• 3D reconstruction is done automatically with radiation software. 

Caution 

• Proper scanning requires the patient to keep still so as to avoid motion artifacts. 
• Patients with metal implants, pregnant patients, or patients with history of allergies need prior disclosure to the technician.
