Ultrasound Real-Time and Convenient Imaging

Pros of Ultrasound

• Fast and Affordable The procedure is quick, with lower costs compared to MRI.
• Real-Time Motion Assessment Ideal for evaluating tendons, joints, and muscle movements during the scan.
• Safe and Repeatable Radiation-free, making it suitable for repeated use.

Cons of Ultrasound

• Limited Depth of View Not ideal for complex internal structures like cartilage.
• Operator-Dependent The accuracy relies heavily on the skill of the technician or doctor.

MRI Detailed Imaging for Complex Conditions

Pros of MRI

• High-Resolution Imaging Captures deep structures like cartilage and fine tendons with precision.
• Comprehensive Diagnosis Best for complex conditions like ligament tears or joint inflammation.

Cons of MRI

• High Cost More expensive than ultrasound.
• Longer Procedure Time May be less convenient for some patients.
• Not Suitable for Everyone Patients with pacemakers or metal implants may not be eligible.

Which Should You Choose?

• Choose Ultrasound if you need a quick, cost-effective scan for less severe injuries, such as tendon or muscle strains.
• Choose MRI if your condition is complex or involves deeper structures, like ligament tears or cartilage issues.
