When you visit a hospital or diagnostic center in Nairobi, your doctor may recommend an X-ray scan to help understand what’s happening inside your body. X-rays are one of the most common, affordable, and effective diagnostic tools in Kenya today. But did you know there are many different types of X-rays, each designed to look at specific parts of the body?

In this detailed guide, we’ll break down the different types of X-rays, how they work, their uses, and what you should know when going for one in Nairobi. Whether you’re visiting a hospital in Westlands, a diagnostic center along Mombasa Road, or a community clinic in Eastlands, this article will help you understand exactly what to expect.

1. What is an X-Ray?

An X-ray is a medical imaging test that uses small amounts of radiation to create pictures of the inside of your body. These images allow doctors to see bones, tissues, and in some cases, internal organs without surgery.

X-rays are:

• Quick – Most scans take only a few minutes.
• Painless – You simply stand or lie still while the machine captures images.
• Widely available in Nairobi – Almost every major hospital and diagnostic center offers X-ray services.
• Affordable compared to CT and MRI scans – making them the first-line diagnostic tool.

2. Why X-Rays Are Important in Nairobi

In a fast-growing city like Nairobi, with its mix of lifestyle-related conditions, accidents, and infectious diseases, X-rays play a central role in medical care. Common reasons doctors in Nairobi order X-rays include:

• Road traffic accidents leading to fractures.
• Chronic back pain among office workers.
• Chest infections such as pneumonia or tuberculosis.
• Dental problems, including wisdom teeth or jaw misalignment.
• Sports injuries common among younger populations.

With healthcare facilities ranging from Kenyatta National Hospital to private centers like Aga Khan, Nairobi West Hospital, and diagnostic clinics in estates such as South B or Parklands, access to different types of X-rays is better than ever before.

3. The Main Types of X-Rays

Now, let’s go deeper into the different types of X-rays, their uses, and when you might need them in Nairobi.

A. Chest X-Ray

Perhaps the most common X-ray in Nairobi, the chest X-ray provides detailed images of the lungs, heart, and chest wall.

Uses in Nairobi:

• Detecting tuberculosis (TB), still a common health concern.
• Checking for pneumonia, especially during cold or rainy seasons.
• Monitoring chronic lung diseases such as asthma or COPD.
• Identifying heart enlargement or fluid around the lungs.

Patient Experience:
A chest X-ray usually takes less than 10 minutes. You’ll stand in front of the machine, take a deep breath, and hold still as the image is captured.

B. Abdominal X-Ray

This X-ray focuses on the stomach, intestines, and surrounding areas.

Uses in Nairobi:

• Detecting bowel blockages (common in emergency cases).
• Identifying swallowed objects in children.
• Checking kidney stones, which are increasingly seen due to lifestyle changes.

Patient Experience:
You’ll usually lie down on a table while the technician takes images from different angles.

C. Bone X-Rays

Bone X-rays are among the most frequently ordered scans, especially in trauma cases.

Uses in Nairobi:

• Detecting fractures after road accidents, common along busy routes like Thika Road or Mombasa Road.
• Diagnosing joint problems such as arthritis.
• Checking for bone infections or deformities in children.
• Assessing bone healing after surgery.

Patient Experience:
The affected limb or part is positioned under the X-ray machine. The process is painless and very quick.

D. Spinal X-Rays

Focused on the cervical (neck), thoracic (upper back), or lumbar (lower back) spine.

Uses in Nairobi:

• Detecting slipped discs or spinal fractures.
• Monitoring chronic back pain among office workers.
• Diagnosing scoliosis (abnormal spinal curvature) in school-aged children.

Patient Experience:
The patient may need to stand or lie in different positions for clear images.

E. Dental X-Rays

These are specialized X-rays taken by dentists to examine the teeth, jaw, and gums.

Types of Dental X-rays include:

• Bitewing X-rays – show the upper and lower teeth in one area.
• Periapical X-rays – focus on one or two teeth in detail.
• Panoramic X-rays – show the entire mouth in one image.

Uses in Nairobi:

• Checking for tooth decay and cavities.
• Planning orthodontic treatments (braces).
• Assessing wisdom teeth before extraction.

Patient Experience:
The dentist may place a small sensor in your mouth or ask you to bite down on a film while the image is taken.

F. Mammography (Breast X-Ray)

Mammography is a specialized X-ray used to detect breast abnormalities.

Uses in Nairobi:

• Early detection of breast cancer – a growing health priority in Kenya.
• Investigating breast lumps or pain.
• Screening women above 40 years or those with family history.

Patient Experience:
The breast is gently compressed between two plates for a few seconds to capture clear images. Though slightly uncomfortable, it is quick and lifesaving.

G. Contrast X-Ray

Sometimes, a special dye (contrast medium) is used to make certain body structures more visible.

Types of contrast X-rays:

• Barium swallow / barium meal – to check the esophagus, stomach, or intestines.
• Intravenous Urogram (IVU) – to evaluate the kidneys and urinary tract.
• Angiography – to examine blood vessels.

Uses in Nairobi:

• Diagnosing digestive system disorders.
• Checking urinary tract infections and kidney stones.
• Investigating heart or brain blood vessel problems.

Patient Experience:
You may drink the contrast dye or have it injected. Images are then taken in sequence.

H. Skull X-Rays

Although less common today due to CT scans, skull X-rays are still used in certain cases.

Uses in Nairobi:

• Detecting fractures after head injuries.
• Checking sinus infections.
• Evaluating bone-related conditions of the skull.

I. Pelvic X-Rays

These scans focus on the pelvic bones and hip joints.

Uses in Nairobi:

• Identifying fractures from falls or accidents.
• Evaluating hip pain in elderly patients.
• Checking joint alignment before surgery.

J. Extremity X-Rays

These focus on hands, feet, arms, and legs.

Uses in Nairobi:

• Detecting sports injuries (common in schools and gyms).
• Diagnosing arthritis or joint swelling.
• Checking bone development in children.

4. Safety of X-Rays

One of the most common concerns patients in Nairobi have is: “Are X-rays safe?”

• X-rays involve a very low dose of radiation, generally considered safe.
• The benefits of diagnosis far outweigh the risks.
• Pregnant women should always inform the doctor or technician before an X-ray.
• Nairobi’s leading hospitals follow strict safety guidelines, using modern machines that minimize exposure.

5. Choosing the Right X-Ray Facility in Nairobi

When selecting where to get your X-ray in Nairobi, consider:

• Accreditation – Ensure the facility is licensed by Kenya Radiation Protection Board.
• Expertise – Look for qualified radiologists and radiographers.
• Equipment – Modern digital X-ray machines give clearer results with less radiation.
• Accessibility – Choose a location close to you; many centers in Nairobi offer same-day walk-ins.
• Cost – X-ray prices vary depending on the type. Chest X-rays may cost as little as KES 1,500, while specialized contrast X-rays may be higher.

6. X-Rays vs. Other Imaging Tests

Patients in Nairobi often wonder why a doctor chooses an X-ray instead of an MRI or CT scan.

• X-rays – Best for bones, chest, and quick checks. Affordable.
• CT Scans – More detailed, especially for complex cases (head injuries, cancers). More expensive.
• MRI Scans – Best for soft tissues, brain, and spinal cord. Longer and more costly.

Doctors usually start with an X-ray and recommend advanced imaging only if necessary.

7. Future of X-Ray Services in Nairobi

With rapid advancements in medical technology, Nairobi is embracing:

• Digital X-rays – Faster results, easier storage, and sharing with doctors.
• AI-powered image analysis – Assisting radiologists in detecting early signs of disease.
• Mobile X-ray units – Increasingly used in remote areas or for bedridden patients.

This means better accuracy, shorter waiting times, and improved patient care.
