COVID recovery CT scan preparation

Overview

This article explains how to prepare for a CT scan during your recovery from COVID-19. A CT scan is a detailed imaging test that uses X-rays to take clear pictures of the inside of your body. After COVID, it is sometimes used to check your lungs and other organs for any lasting effects.

It is common. Many people who had COVID-19, especially those who were very ill or have ongoing symptoms, are referred for a CT scan by their doctor to check that their lungs are healing well.

It affects people of all ages who are recovering from COVID-19 and who have symptoms that need a closer look. People with other health conditions such as asthma, diabetes, or heart disease may be more likely to need a scan.

Symptoms

Common symptoms

• Shortness of breath, especially with mild activity
• A persistent cough that lasts for weeks
• Chest pain or tightness
• Unusual tiredness or fatigue

Symptoms in children

• Breathing faster than usual or working hard to breathe
• A cough that does not go away
• Pale or mottled skin

Symptoms in older adults

• Difficulty catching your breath during daily tasks
• Confusion or unusual sleeping patterns
• A feeling of weakness or decreased ability to walk

Causes

Main causes

• COVID-19 infection, especially if it was severe
• Ongoing symptoms after the infection has cleared
• Suspected complications like lung inflammation or blood clots

Risk factors

• Requiring hospital care for COVID-19
• Long-standing lung or heart conditions
• Older age or a weakened immune system

When to see a doctor

See a doctor urgently if:

• Your breathing is getting worse despite resting
• You develop sudden chest pain or cough up blood
• You feel confused, disoriented, or extremely weak

Book a routine appointment if:

• You have symptoms that last beyond a few weeks
• You want to discuss whether a CT scan is appropriate for your recovery

Diagnosis

COVID-19 is first diagnosed with a swab test. For symptoms after recovery, a CT scan is one of the most helpful tests. It lets your doctor look at your lungs and other tissues in detail to see if there are any lasting issues.

Tests that may be done

• CT scan of the chest
• Blood tests to check for inflammation or clotting
• Breathing tests to measure lung capacity

What to expect at your appointment

When you arrive, the technician will place you on a sliding table. The table moves into a donut-shaped machine. You will be asked to lie still and sometimes hold your breath for a few seconds. It is painless, and you can go home soon after.

Treatment

Treatment after a CT scan depends on the results. If the scan is normal, you may only need time and rest. If the scan shows damage or inflammation, your doctor will suggest a treatment plan tailored to you. This might include breathing exercises, rehabilitation, or medications to manage symptoms.

Self-care at home

• Take rest breaks during the day and pace your activities.
• Do breathing exercises if your doctor recommends them.
• Avoid smoking and exposure to smoke or polluted air.
• Follow your doctor's advice on how to safely resume exercise.

Medical treatments

Your healthcare team may recommend supervised physical rehabilitation, inhalers to help open your airways, or medicines to reduce inflammation or prevent blood clots. Always take medicines exactly as prescribed and talk to your doctor before adding anything new.

Living with this condition

Recovery from COVID can take time, even after a clear scan. Give yourself a gentle routine, get enough sleep, and ask for help with daily tasks when you need it. Your doctor will tell you what your scan means and what kinds of activities are safe.

Lifestyle tips

• Stay well-hydrated and eat nutritious meals
• Include gentle movement, like walking, if it feels okay
• Keep up with follow-up appointments

Diet and exercise

Eat a balanced diet full of vegetables, fruits, whole grains, and lean proteins to support healing. When it comes to exercise, start very slowly and gradually increase as you feel better. Always check with your doctor before starting a new routine.

Mental health and emotional wellbeing

It is normal for recovery to feel stressful. You may feel anxious about your health or frustrated by slow progress. Talking to your doctor, a counsellor, or a trusted friend can help. You are not alone.

Prevention

You cannot prevent the need for a CT scan if your doctor recommends one, because the scan is a way to check your health. To lower your chance of severe COVID, stay up to date with recommended vaccines, practice good hygiene, and manage any underlying conditions.

Vaccines

COVID-19 vaccines reduce the risk of serious illness and complications. Talk to your doctor or pharmacist about the right vaccine for you.

Screening programmes

Routine screening for post-COVID lung problems is not standard. Your doctor will request a CT scan only if you have symptoms that need investigation.

Complications

If left untreated

• Lung inflammation or scarring may not heal as quickly
• Breathlessness could limit your usual activities
• Blood clots could cause serious problems if not detected and treated

Long-term outlook

The outlook is generally good. Most people who have a CT scan during COVID recovery are reassured by the results. If a problem is found, early recognition and treatment help most people improve over time.
