Sports imaging
What is the difference between musculoskeletal ultrasound and MRI for sports injuries?
Doctor’s answer
Musculoskeletal ultrasound is useful for superficial tendons, muscles, bursae, and selected ligaments. It allows dynamic examination and can guide injections. MRI provides a broader view of the inside of a joint, cartilage, bone marrow, and deeper tissues. The choice depends on the injured area and the structure being assessed.

When does a sports injury need an X-ray, and when is MRI more useful?
X-rays mainly assess fractures, dislocations, and obvious bone abnormalities. MRI is better suited to ligaments, menisci, cartilage, tendons, muscles, and occult fractures. When an X-ray is normal but pain, swelling, or loss of function persists, a clinician may arrange repeat X-rays, MRI, or CT.
Can insufficient sleep increase sports injury risk and slow recovery?
Insufficient sleep can reduce reaction speed, attention, and movement control and can interfere with muscle repair, pain regulation, and recovery after training. Athletes should keep a regular schedule and allow enough sleep for their training load. Persistent insomnia, marked daytime sleepiness, or snoring with pauses in breathing warrants assessment.
Should athletes use static stretching or a dynamic warm-up before exercise?
Begin with 5 to 10 minutes of low-intensity activity, followed by a sport-specific dynamic warm-up such as high knees, lunges, leg swings, and progressive accelerations. Longer static stretches are generally better placed after training or in a separate flexibility session.
