tendon CT scan preparation

Overview

A CT scan (computed tomography scan) uses a series of X-rays to create detailed pictures of the inside of your body. A tendon CT scan focuses on your tendons — the strong, flexible cords that connect muscles to bones. It helps doctors look closely at a tendon that is painful, injured, or not working properly. This scan is usually quick, painless, and done as an outpatient.

Yes. CT scans are a common imaging test, and tendon scans are regularly used when doctors need a closer look at a tendon injury or suspect a tear, inflammation, or other problems.

Anyone can be referred for a tendon CT scan. They are often done for people with sports injuries, overuse injuries, or age-related tendon wear. Your doctor will recommend it if they think a CT scan is the best way to see what's going on.

Symptoms

Common symptoms

• Pain or tenderness along a tendon
• Swelling or warmth near a joint
• Weakness or difficulty moving the affected limb
• A feeling of popping or snapping at the time of an injury

Symptoms in children

• Children may limp or avoid using an arm or leg
• They may cry when the area is moved
• They might complain of pain in a joint or muscle

Symptoms in older adults

• Older adults may notice stiffness and pain in a tendon, especially around the shoulder, heel, or elbow
• They may have trouble with daily activities like climbing stairs or lifting items

Causes

Main causes

• Tendon injuries often happen during sports or heavy lifting
• Overusing a tendon through repeated movements
• Age-related wear and tear on tendons
• Conditions such as rheumatoid arthritis that cause inflammation

Risk factors

• Playing sports that involve jumping, throwing, or running
• Doing repetitive work or hobbies
• Getting older
• Having diabetes or being a smoker
• Using certain medicines, such as the type known as steroid tablets, for a long time

When to see a doctor

See a doctor urgently if:

• If you have a sudden injury and cannot move the affected limb
• If you heard a snap or popping sound and have severe pain
• If the area looks misshapen or feels extremely weak

Book a routine appointment if:

• If you have joint or tendon pain that lasts more than a few days
• If you have swelling, stiffness, or tenderness that limits your daily activities
• If you have already had an X-ray and the doctor wants a more detailed scan

Diagnosis

A doctor will first ask about your symptoms, examine you, and may suggest an X-ray or ultrasound. If they need a more detailed view of a tendon, they may order a CT scan. The scan uses special equipment to take 3D pictures of the area.

Tests that may be done

• Physical examination
• X-ray
• Ultrasound
• CT scan with or without contrast dye
• Sometimes MRI

What to expect at your appointment

Before the scan, you may be asked to change into a gown. If contrast dye is used, it is given through a small needle in your arm. You lie on a padded table that slides into the scanner. The machine makes some whirring noises, but you won't feel anything. You'll be asked to stay still for a short time. The whole appointment usually takes 15 to 30 minutes. Afterward, you can go home and return to your normal routine.

Treatment

The right treatment depends on what the CT scan shows. Many tendon problems improve with rest, physical therapy, and time. More serious injuries, such as a full tendon tear, may need a specialist opinion and possibly surgery. Your doctor will discuss the results with you and create a plan that fits your needs.

Self-care at home

• Rest the affected area and avoid activities that cause pain
• Use ice packs for 15-20 minutes a few times a day to reduce swelling
• Keep the limb raised when possible
• Follow your doctor's advice about when to start moving again

Medical treatments

Non-surgical treatment may include working with a physiotherapist, using pain-relieving medicines as recommended by your doctor, and wearing a brace, splint, or boot to support the tendon. Some people benefit from injections or other procedures, but these are always decided by your specialist.

When is surgery considered?

Surgery is usually considered only if the tendon is completely torn, if the injury does not get better with non-surgical care, or if the scan shows a problem that needs a repair. Your surgeon will explain the procedure, benefits, and risks before you decide.

Living with this condition

After a tendon problem, you may need to adjust how you do everyday tasks. Use helpful devices like a cane or a reaching aid if your doctor suggests them. Follow your rehabilitation plan, and don't rush back to heavy activity before your healthcare team says it's safe.

Lifestyle tips

• Warm up and stretch properly before exercise
• Strengthen muscles gradually to support your joints and tendons
• Avoid sudden increases in exercise intensity or duration
• Take rest days to let your tendons recover

Diet and exercise

Eating a balanced diet with plenty of fruits, vegetables, and protein can help your body repair tissues. Gentle exercises such as walking, swimming, or cycling may be the right starting point, but check with your physiotherapist about what is safe for your specific tendon problem.

Mental health and emotional wellbeing

Living with pain or waiting for a diagnosis can be stressful. It's normal to feel anxious or low. Talk to your doctor about how you're feeling, and consider reaching out to a counselor or support group if you need more help.

Prevention

Many tendon injuries can be prevented or reduced. Regular exercise that strengthens the muscles around your joints, proper technique during sports, and allowing recovery time all help. But not every tendon problem can be avoided, especially as we get older.

Complications

If left untreated

• A torn tendon that is not treated can lead to permanent weakness or loss of movement
• Chronic pain may continue for months or years
• Healing might take longer and the tendon could develop scar tissue

Long-term outlook

Most tendon problems respond well to care. The CT scan is a safe, helpful way to get an accurate picture so your treatment can be as effective as possible. With the right plan, many people return to the activities they enjoy.
