Is contrast always needed?

Only if inflammation, infection, or tumor is suspected.

Can I drive after the scan?

Yes, unless you opted for sedation.

What if I’m claustrophobic?

We offer an open-bore 3T scanner or mild oral sedation.

When will I receive results?

Standard: 4–6 hours. Urgent cases: within 1 hour.

What is the estimated cost of an MRI for the thumb?

The cost of an mri for thumb can vary depending on several factors, including your specific location, insurance plan, and whether contrast material is used. For precise pricing and insurance information, please contact our billing department.

Is an MRI THUMB safe for children?

Yes, MRI is considered a very safe imaging modality for children because it does not use ionizing radiation. For young children who may have trouble staying still, sedation may be coordinated by your referring doctor to ensure we can obtain high-quality, motion-free images. This is an important consideration in pediatric care.

MRI of the Thumb an Overview

MRI thumb is a specialized Magnetic Resonance Imaging exam that zeroes in on:

Thumb bones (distal phalanx, proximal phalanx, first metacarpal)
Ligaments—especially the ulnar collateral ligament (UCL)
Tendons such as EPL and FPL
Surrounding soft tissues and joint capsule

How It Works

A strong magnetic field and radio waves create high-contrast cross-sectional images. The result? Your doctor sees injuries that X-rays often miss, guiding the best treatment path.

List of Parameters

MRI Thumb Parameters Considered

FOV: 140 × 70 mm SFOV optimized for thumb anatomy
Slice thickness: 2 mm axial, coronal, sagittal
Sequences: T1 TSE, T2 STIR, PD fat-sat
Matrix: 256 × 192 for crisp detail
TR/TE: Tailored to our 3T magnet specs for maximum clarity

When to Take Test

Detect ligament tears (UCL, RCL)
Evaluate tendon injuries (EPL, FPL)
Spot occult fractures or bone bruises
Assess early arthritis or synovitis

Benefits

MRI of Thumb Benefits:

Non-invasive & radiation-free
Superior soft-tissue contrast—see what X-rays can’t
Directly guides surgical vs. conservative treatment
Digital report with annotated images delivered same day

Conditions Diagnosed with MRI for Thumb

Gamekeeper’s / skier’s thumb (UCL tear)
De Quervain’s tenosynovitis
Scaphoid fracture missed on X-ray
Basal thumb arthritis
Flexor/extensor tendon ruptures

Preparing for Test

Preparation for MRI Thumb Scan

Remove all metallic objects—jewelry, watches, belts
Wear metal-free clothing or change into our gown
Inform staff about implants, pregnancy, or claustrophobia
Fasting not required—eat normally unless contrast is planned

Pre-requisites

Referral note from orthopedician or GP
Bring previous imaging reports for comparison

Best Time to Take the MRI Thumb

Within 1–2 weeks of acute injury for optimal soft-tissue detail
Morning slots reduce waiting time and fit busy schedules

Eligibility

Adults and children >5 years (cooperation permitting)
Pregnancy: Second or third trimester only if clinically essential

Step-by-Step Procedure at Cadabams Diagnostics

Check-in & Screening (5 min)
Positioning: Hand palm-up in dedicated thumb coil
Scanning: 20–30 min with intermittent instructions
Radiologist review before you leave

Caution Before the Test

Disclose tattoos with metallic ink—they may heat up
Sedation available for severe claustrophobia (request in advance)

Risks and Limitations of MRI Thumb Scan

Safety

No radiation—safe for repeated imaging
Contrast dye (gadolinium) is low-risk and used only when needed

Contraindications

Pacemaker or non-MRI-safe implants
Severe claustrophobia (we offer open-bore 3T and sedation)

Limitations

May miss tiny cortical fractures—a follow-up CT scan can complement the findings.

Test Results

Results and Interpretations

Finding / Observation	Description	General Interpretation / Significance
UCL thickness	3 mm partial disruption	Skier’s thumb grade II
EPL tendon	Intact, normal signal	No tendon rupture
First CMC joint	Mild joint-space narrowing	Early osteoarthritis
Bone Marrow Edema	An area of bright signal within the bone marrow on fluid-sensitive sequences.	This is a non-specific sign of stress. It can indicate a hidden fracture, bone bruise, inflammation from arthritis, or infection.
Synovial Enhancement	Brightness of the joint lining (synovium) after the injection of contrast dye.	Suggests active inflammation (synovitis), a hallmark of conditions like rheumatoid arthritis or an infection.
Soft Tissue Mass	A well-defined, fluid-filled sac seen adjacent to a joint or tendon sheath.	Most commonly represents a ganglion cyst. Other masses would be described by their size, location, and characteristics to determine if they are benign or require further evaluation.
