Select Your CT Thorax Protocol
Three distinct CT Thorax scan types — each designed for a specific clinical purpose. Click to explore details, indications, and pricing for each.
CT Thorax Plain
NCCT — No contrast, no fasting. Walk in & scan. Pneumonia, pleural effusion, TB, masses & fractures.
Most Common · No PrepCT Thorax Screening
LDCT — Low-dose lung cancer screening for smokers & high-risk patients. Annual protocol.
Lung Cancer ScreeningCT Thorax Contrast
CECT — Iodine contrast for tumour staging, PE, lymphoma & vascular evaluation. Fast 4–6h.
Tumour · Vascular · OncologyThe most common and versatile CT Thorax protocol. Non-contrast (NCCT) means no dye injection, no fasting, and no waiting — walk in and scan. Provides excellent detail of lung parenchyma, airways, pleural space, mediastinum, chest wall, and bones. The first-line investigation for most chest complaints, emergency settings, and routine evaluation.
- ✅No preparation required: Eat, drink, and take medications normally — simply arrive and scan
- ✅Best for: Pneumonia, TB, pleural effusion, pneumothorax, lung collapse, rib fractures, mediastinal masses
- ✅Lung parenchyma detail: Ground-glass opacities, consolidation, emphysema, interstitial changes, bronchiectasis
- ✅COVID-19 assessment: HRCT-equivalent thin-slice protocol for COVID lung involvement and severity scoring
- ✅Emergency ready: Available 24/7 at all 9 branches — no appointment needed for urgent cases
A specialised annual lung cancer screening protocol using significantly reduced radiation dose — up to 75–80% less radiation than standard CT Thorax — while maintaining excellent sensitivity for detecting small lung nodules as small as 3–4mm. Proven to reduce lung cancer mortality by 20–25% in high-risk populations. Recommended annually for current and former heavy smokers aged 50–80 and others at elevated lung cancer risk.
- ✅Low radiation dose: LDCT uses up to 80% less radiation than standard CT — comparable to a mammogram
- ✅Annual protocol: Recommended once yearly for high-risk patients — builds a nodule surveillance baseline
- ✅Lung-RADS reporting: Structured Lung-RADS scoring system guides follow-up recommendations clearly
- ✅Early detection: Detects Stage I lung cancer when 5-year survival exceeds 85% — before symptoms develop
- ✅No contrast or fasting: Quick, simple, annual scan — no preparation required
Contrast-enhanced CT Thorax (CECT) uses an intravenous iodine-based contrast injection to highlight blood vessels, tumours, lymph nodes, and areas of inflammation with much greater detail than plain CT. Essential for lung cancer staging, pulmonary embolism diagnosis, lymphoma evaluation, mediastinal masses, and complex vascular conditions. Requires 4–6 hours fasting before the scan.
- ✅Tumour staging: Vascular invasion, lymph node involvement, and distant metastasis assessment for lung cancer staging
- ✅Pulmonary embolism (CTPA): Emergency protocol for blood clot detection in pulmonary arteries — time-critical diagnosis
- ✅Lymphoma staging: Mediastinal and hilar lymph node size, enhancement, and distribution for staging
- ✅Vascular abnormalities: Aortic aneurysm, dissection, pulmonary arteriovenous malformations
- ✅Treatment response: Monitoring tumour size change after chemotherapy or radiotherapy

What is a CT Thorax Scan?
A fast, non-invasive X-ray–based scan that creates detailed cross-sectional pictures of the entire chest — lungs, airways, heart, vessels, mediastinum, and chest wall.
What CT Thorax Examines
CT Thorax produces high-resolution cross-sectional images of the lung parenchyma, bronchi, trachea, pleural spaces, mediastinum (heart, pericardium, aorta, lymph nodes, thymus), oesophagus, chest wall (ribs, sternum, muscles), and diaphragm. Thin-slice reconstruction enables both routine lung windows and high-resolution parenchymal analysis in the same acquisition.
How 160-Slice CT Works
Our 160-Slice MDCT scanner rotates 360° in under a second, capturing 160 simultaneous X-ray detector rows per rotation. The entire thorax is scanned in a single breath-hold of 5–10 seconds — minimising motion blur. Advanced iterative reconstruction algorithms convert the raw data into razor-sharp 0.5mm thin-slice images with low radiation dose protocols applied automatically.
CT Thorax vs Chest X-Ray
Chest X-ray misses approximately 20–30% of lung cancers, cannot detect ground-glass opacities, subtle interstitial disease, or mediastinal masses hidden behind the heart. CT Thorax reveals all structures in cross-section — detecting abnormalities invisible on plain film. For any clinical scenario where a definitive answer matters, CT Thorax is significantly more informative than X-ray.
Radiation & Safety
CT Thorax uses controlled low-dose ionizing radiation, carefully calibrated to the minimum needed for diagnostic quality. Our LDCT Screening protocol uses up to 80% less radiation than standard CT — comparable to a mammogram. Our team follows ALARA principles at all times. Avoided in pregnancy unless clinically urgent. Contrast-related allergy or kidney issues require prior disclosure.
Chest Structures CT Thorax Scans
From lung parenchyma to chest wall — comprehensive imaging of every thoracic structure in one scan.
Lung Parenchyma
The primary purpose of CT Thorax — detailed lung tissue evaluation.
- Consolidation, ground-glass opacity, crazy-paving
- Pulmonary nodules and masses (Lung-RADS grading)
- Emphysema — centrilobular, panlobular, paraseptal
- Interstitial lung disease (fibrosis, UIP, NSIP)
- Bronchiectasis, tree-in-bud, mucoid impaction
- Atelectasis, collapse, air trapping
Airways
Trachea and bronchial tree — assessed for narrowing, masses, and wall changes.
- Tracheal stenosis, tumours, malacia
- Bronchial wall thickening in asthma/COPD
- Endobronchial lesions and foreign bodies
- Bronchiectasis distribution & severity
- Mucus plugging patterns
- Airway compression by lymph nodes/mass
Pleura
The lung lining — pleural disease is reliably detected and characterised.
- Pleural effusion — size and characteristics
- Pleural thickening and calcification
- Pleural mesothelioma staging
- Empyema vs simple parapneumonic effusion
- Pneumothorax and hydropneumothorax
- Pleural plaques (asbestosis)
Mediastinum
The central chest compartment — masses here are best evaluated by CT.
- Thymic masses and thymoma staging
- Anterior mediastinal lymphoma

20+ pack-years, quit within the last 15 years, aged 50–80
Family History
First-degree relative with lung cancer — especially if combined with any smoking
Occupational Exposure
Asbestos, silica, radon, chromium, arsenic, or diesel exhaust occupational exposure
Previous Lung Cancer
History of treated lung cancer — surveillance for recurrence or new primary

Benefits of CT Thorax Scan
Why CT Thorax is far superior to chest X-ray and essential for accurate pulmonary and thoracic diagnosis.
Detects What X-Ray Misses
CT Thorax finds 20–30% of lung cancers invisible on X-ray — small nodules, ground-glass opacities, retrocardiac masses, and mediastinal disease invisible on plain film.
Early Lung Cancer Detection
LDCT Screening detects Stage I lung cancer when 5-year survival exceeds 85%. Annual screening for high-risk patients has proven to reduce lung cancer deaths by 20–25%.
Emergency Rapid Diagnosis
CT Thorax completed in a single breath-hold of 5–10 seconds — critical for pulmonary embolism, pneumothorax, and aortic emergencies where every minute matters.
Precise Staging
CECT Thorax provides TNM staging accuracy for lung cancer — tumour size, nodal involvement, and vascular invasion — the exact information oncologists need for treatment planning.
How to Prepare for CT Thorax Scan
Preparation depends on which protocol your doctor has prescribed — plain and screening need almost none, contrast needs fasting.
Do's – Before Your Scan
- ✓Arrive 15–20 minutes early for registration and safety screening
- ✓Bring your doctor's prescription and any previous chest X-rays, CT films, or reports
- ✓Inform staff about all medications — especially Metformin, blood thinners, and inhalers
- ✓Declare any allergy to iodine or contrast dye — especially if CECT is prescribed
- ✓Tell us if you are pregnant, breastfeeding, or have kidney disease (kidney disease + contrast = risk)
- ✓For CECT: fast 4–6 hours before scan — no food or milk, clear water is allowed
- ✓Practise deep breathing and breath-holding — you'll be asked to hold for 5–10 seconds during scanning
- ✓Wear comfortable clothing — loose top preferred, no metal zippers or buttons on the chest
Don'ts – What to Avoid
- ✗Do NOT eat or drink 4–6 hours before CECT (contrast) — plain and screening have no restriction
- ✗Avoid metal zippers, bra underwire, or metallic accessories on the chest
- ✗Do not bring keys, phone, coins, or metal items into the scan room
- ✗Do NOT take Metformin 48 hours before and after CECT (consult your doctor first)
- ✗Avoid breastfeeding 24–48 hours after contrast injection (pump and discard)
- ✗Do NOT move, breathe, or cough during active scan acquisition — stay absolutely still
- ✗Avoid hiding your medical history — kidney disease or allergy to contrast can be life-threatening
- ✗Do NOT delay if you have severe breathlessness or suspected PE — come immediately to any branch
What Happens During
Your CT Thorax Scan?
A fast, simple, and painless process. The actual CT scan of the thorax takes just 5–10 seconds of breath-hold time.
Registration & Prescription Review
Present your doctor's prescription at reception. Staff verifies your details, identifies which CT Thorax protocol (plain / screening / contrast) has been prescribed, and prepares your file.
Safety Screening & Preparation
Complete a brief health questionnaire — allergies, kidney function, Metformin, pregnancy, previous contrast reactions. For CECT, an IV cannula is placed. For plain and screening, no injection is needed.
Positioning on the CT Table
You lie on your back, arms raised above your head. The table slides smoothly through the open CT gantry. The technologist positions the scan range to cover the entire thorax from apex to costophrenic angles.
The Scan (5–10 Second Breath-Hold)
The technologist instructs you to take a deep breath and hold it. The CT scanner rotates silently and rapidly — the entire thorax is captured in a single 5–10 second breath-hold. Most patients complete this comfortably. The full procedure takes 10–20 minutes.
Radiologist Report Same Day
Our MD Radiologist reviews all CT Thorax images using dedicated lung, mediastinal, and bone windows — then prepares a structured report. LDCT Screening studies include Lung-RADS scoring. Reports delivered same day via WhatsApp and email.
Breath-Hold Is Everything
The most important thing you can do during CT Thorax is hold your breath completely still during the 5–10 second scan acquisition. Even a small breath causes motion blur that degrades image quality — especially for detecting small nodules in lung cancer screening. Our technologist will coach you through a practice breath-hold before scanning. Most patients find it easy. If you have severe breathlessness, inform us when booking — we will adapt the protocol accordingly.
Suspected PE or Chest Emergency? Walk In Immediately
Pulmonary embolism, tension pneumothorax, and aortic emergencies are life-threatening. Our CT Thorax — including emergency CTPA for PE — is available 24 hours, 7 days a week, 365 days a year at all 9 branches. Walk in directly for any chest emergency — no appointment needed. Call us on +91 79 6969 0900 if you are unsure which branch to attend.
Frequently Asked Questions
Everything you need to know about CT Thorax Scan — plain, screening, and contrast — answered clearly.
What Our Patients Say
Trusted by pulmonologists, oncologists, and patients across Ahmedabad for precise, reliable CT Thorax imaging.
I'm a 55-year-old ex-smoker. My doctor suggested annual LDCT lung cancer screening. The scan was quick and the Lung-RADS report was very detailed — my pulmonologist was impressed with the quality. Caught a small nodule early that needed monitoring. Affordable, fast, and potentially life-saving.
My father had suspected pneumonia with pleural effusion — needed urgent CT Thorax Plain at 11pm. The Naroda branch was fully operational and the NCCT was done within 20 minutes. Report on WhatsApp by 1am. His pulmonologist could start the right treatment immediately. Excellent 24/7 service!
Needed CECT Thorax for lymphoma staging — very affordable compared to hospitals. The contrast CT was well-organised, the report clearly documented all lymph node stations and measurements for staging. My oncologist confirmed the report met all the requirements for treatment planning. Highly recommend!
