X-ray Results Explained in Nigeria

Understanding what your X-ray shows — the most basic but often confusing imaging report

X-rays (radiographs) are the oldest and most widely available medical imaging — using low-dose ionising radiation to produce images of dense structures, particularly bones. Plain X-rays are quick, cheap, and available at virtually all Nigerian hospitals. They are invaluable for: fractures, pneumonia, heart and lung size assessment, bowel obstruction, tuberculosis, and joint assessment. However, X-rays have significant limitations — they cannot see soft tissues well, they show a two-dimensional shadow of three-dimensional structures, and they require careful interpretation. This guide explains common X-ray findings and terminology.

Signs and Symptoms

✓ Types of X-rays and their uses:
✓ Chest X-ray (CXR): most commonly ordered. Lung fields, heart size, pulmonary vessels, bones of chest
✓ Abdominal X-ray (AXR): bowel gas pattern, calcifications (kidney stones, gallstones occasionally), free air under diaphragm (perforated bowel)
✓ Skeletal X-rays: fractures, joint arthritis, bone tumours, metabolic bone disease
✓ Spine X-ray: scoliosis, fracture, disc space narrowing, spondylolisthesis

Risk Factors

When to Seek Help

Chest X-ray is indicated forCough > 2 weeks (TB screening), breathlessness, chest pain, haemoptysis (coughing blood), assessment of heart size in heart failure, pre-operative assessment, pulmonary TB follow-up
Bone X-ray is indicated forAfter any significant trauma, persistent pain after injury, suspected fracture
Abdominal X-ray forSuspected bowel obstruction (sudden severe vomiting + no bowel movement), free gas in peritonitis, kidney stone assessment (though CT KUB is better)

Tests & Diagnosis

🧪 Chest X-ray — how to read systematically
ABCDE approach: A = Airway (trachea midline?), B = Bones (rib fractures, density), C = Cardiac (heart size < 50% of chest width = normal cardiac silhouette), D = Diaphragm (flat vs raised, free air below), E = Everything else (lung fields for infiltrates, pleural effusion, pneumothorax)
🧪 Lung appearances on CXR
Normal: black (air-filled). Consolidation: white fluffy opacity — pneumonia, fluid, blood. Pleural effusion: white at lung base, fluid meniscus. Pneumothorax: black space with no lung markings, collapsed lung edge visible. TB: upper zone infiltrates, cavitation, hilar lymphadenopathy. Cardiomegaly: heart > 50% chest width
🧪 Bone X-ray terms
Fracture types: transverse, oblique, spiral, comminuted (multiple fragments), compound (skin broken). Periosteal reaction: new bone formation — infection, tumour, healing. Lytic lesion: area of bone destruction — infection, tumour, myeloma. Sclerotic lesion: dense area — healing fracture, bone island, metastasis (prostate, breast)
🧪 Abdominal X-ray terms
Air under diaphragm: perforated bowel — surgical emergency. Dilated loops of bowel: obstruction. Calcification in right iliac fossa: appendicolith (may indicate appendicitis). Staghorn calculus: large branching kidney stone filling the renal pelvis

Treatment Options

1
When X-ray is normal but symptoms persist
A normal X-ray does not exclude all pathology — early pneumonia, small pleural effusion, soft tissue injuries, and many tumours may not be visible on plain X-ray. CT, ultrasound, or MRI provides more detail
2
Follow-up X-rays
Some conditions require follow-up X-rays to confirm resolution — pneumonia (6 weeks CXR to ensure resolution and exclude underlying lesion), fracture (4–6 weeks to confirm healing)

Frequently Asked Questions

My chest X-ray showed 'cardiomegaly' — do I have heart disease?
Cardiomegaly (enlarged heart shadow) on chest X-ray warrants further investigation but does not confirm a specific diagnosis. Common causes: heart failure, dilated cardiomyopathy, hypertensive heart disease, valvular disease, pericardial effusion, or even a technically suboptimal X-ray (taken during expiration, AP rather than PA projection). An echocardiogram (cardiac ultrasound) is needed for definitive assessment.
My spine X-ray says 'moderate degenerative changes' — is this serious?
Degenerative changes on spine X-ray (disc space narrowing, osteophytes) are extremely common — present in over 80% of people over 50 on imaging. The radiological findings frequently don't correlate with symptoms. Many people with dramatic degenerative changes on X-ray have no back pain; many people with severe back pain have minimal changes. Clinical assessment (your symptoms, neurological examination) is more important than the X-ray appearances.
Should I avoid X-rays during pregnancy?
For clinically necessary X-rays of non-abdominal areas (chest, limbs, skull), the radiation dose to the fetus is negligible and the scan should not be delayed if needed. Abdominal and pelvic X-rays should be avoided in the first trimester unless essential — and a lead apron is used when possible. Always tell the radiographer if you are pregnant or might be pregnant.
How do I get my X-ray images after a scan?
At Nigerian hospitals, X-rays are provided on physical film or on a CD/DVD. The radiologist's report is a separate written document. Keep both — bring them to all follow-up appointments and specialist consultations. Digital X-rays can sometimes be stored on a hospital's PACS system and accessed on a subsequent visit without needing the physical film.
