CT Right Ankle Joint

A CT ankle scan is a painless X-ray–based test that creates detailed cross-sectional images of the bones, joints, and soft tissues around the ankle. Unlike a regular X-ray, it can show hairline fractures, hidden ligament damage, or early arthritis changes.

1. Non-contrast CT ankle – routine bone evaluation
2. CT ankle with contrast – to assess infection or tumors
3. CT ankle 3D reconstruction – for surgical planning

• Slice thickness: 0.625 mm for finest detail
• Field of view: 14 cm centered on ankle joint
• KVP: 100–120 kV optimized for bone vs soft tissue
• Reconstruction algorithms: Bone, soft-tissue, and 3D volume-rendered views

• Confirm or rule out ankle fracture (especially talar, calcaneal)
• Evaluate ankle joint space narrowing (early arthritis)
• Detect bone infection (osteomyelitis)
• Identify bone tumors or cysts
• Check hardware position after surgery

Common situations:

• Persistent ankle pain after a fall or sports injury
• Suspected ankle fracture not visible on plain X-ray
• Swelling or instability lasting >2 weeks
• Pre-surgical planning for ankle fusion or ligament repair
• Monitoring healing after a cast or surgery

• Fast: Entire visit typically <30 minutes
• Precise: 3D model lets surgeons “fly through” the joint
• Accessible: Same-day booking online or walk-in
• Comfortable: Open design reduces claustrophobia

• Fractures: Lateral malleolus, medial malleolus, talus, calcaneus
• Ligament tears: Anterior talofibular, deltoid ligament avulsions
• Osteochondral lesions
• Tarsal coalition
• Septic arthritis

• Technology: Low-dose, multi-slice CT with metal-artifact reduction
• Time taken: 5–10 minutes actual scan
• Report ready: Within 2 hours (priority cases in 30 minutes)
• Locations: 12 centers across Bangalore & Hyderabad

• Clothing: Wear loose cotton clothes; avoid metal zippers, jewelry.
• Fasting: Not needed for non-contrast scans.
• Contrast cases: Fast 3–4 hours if contrast is requested.
• Medications: Continue regular meds unless advised otherwise.

• Valid doctor’s prescription (digital or hard copy)
• Previous X-rays or MRI reports (if any)
• Kidney function test (if contrast is planned)

• Acute injury: Within 24–48 hours for accurate fracture detection.
• Follow-up: 6–8 weeks post-surgery or cast removal.
• Pain flare-ups: Anytime symptoms worsen unexpectedly.

• Adults: No upper age limit.
• Children: Can undergo scan with pediatric protocol (lower dose).
• Contraindications: Pregnancy (relative) for non-urgent scans.

1. Check-in: Reception verifies ID and prescription.
2. Safety check: Remove metallic items; change into gown if needed.
3. Positioning: Lie on the scanner table, ankle in a soft brace.
4. Scan: Table moves through the ring for ~30 seconds; remain still.
5. Contrast (if ordered): IV line inserted, scan repeated after 60 seconds.
6. Completion: Radiologist reviews images; preliminary report in 30 minutes.

• Inform staff about pregnancy or breast-feeding.
• Disclose allergies to iodine or shellfish.
• Bring an escort if you have mobility issues. e taking the medication Metformin (Glucophage).

• Radiation dose: ~0.3 mSv (equal to about 1 month of natural background; minimized with low-dose protocols)
• Not ideal for: Very early stress injuries better seen on MRI
• Contrast dye risks: Rare allergy, kidney concerns—screened beforehand
