About The Test
- Duration: 15 minutes from check-in to exit
- Preparation: No fasting or special diet
- Results: Same day, often in under 30 minutes
- Equipment: High-resolution digital X-ray, NABL-accredited lab
- Safety: Radiation dose <0.1 mSv—lower than a trans-continental flight
What is Chest PA View X-Ray Scan?
Definition
The Postero-Anterior (PA) projection means you stand facing the detector while the X-ray beam passes from your back (posterior) to your front (anterior). This angle provides the clearest view of the lungs, heart, and ribs.
Difference Between PA and AP View
- PA: Patient stands upright, chest against detector—preferred for detail.
- AP: Patient lies or sits—used in emergencies or for immobile patients.
Digital vs. Conventional Film
Digital imaging uses electronic sensors instead of film. Benefits include:
- Instant image preview
- Lower radiation dose
- Easy sharing with specialists via secure cloud link
Types of Chest PA View X-Ray Scan
| Type | Use Case | Time |
|---|---|---|
| Standard PA Single | Routine screening, cough, chest pain | 5 min |
| PA & Lateral Combo | Detailed lung or rib evaluation | 10 min |
| Portable Bedside PA | ICU or immobile patients | 5 min |
List of Parameters
- Lung field clarity & symmetry – checks for pneumonia or tumor
- Cardiac size & shape – screens for cardiomegaly
- Costophrenic angle sharpness – detects pleural effusion
- Diaphragm position – signs of air trapping or collapse
- Bony thorax integrity – looks for fractures or lesions
Why This Test
- Infection screening: pneumonia, tuberculosis, lung abscess
- Trauma assessment: rib fractures, pneumothorax
- Chronic disease monitoring: COPD, pulmonary fibrosis, heart failure
- Pre-surgical clearance for general anesthesia
When to Take Test
- Persistent cough lasting >2 weeks
- Chest pain or tightness
- Shortness of breath or wheezing
- Pre-employment health checks for IT, aviation, or construction roles
- Visa medicals for the UK, Gulf, or Schengen countries
- Follow-up for known TB, pneumonia, or heart failure
Benefits
Benefits of Taking the Chest PA View X-Ray Scan
- Quick & non-invasive – no needles or contrast dye
- Cost-effective – lower price than CT or MRI
- High accuracy for common lung and heart conditions
- Digital sharing – reports sent instantly to your doctor via secure link
Illnesses Diagnosed with Chest PA View X-Ray Scan
| Condition | How the Scan Helps |
|---|---|
| Pneumonia | Shows localized opacity or consolidation |
| Tuberculosis | Reveals cavitations or nodular infiltrates |
| Cardiomegaly | Measures heart-to-thorax ratio >0.5 |
| Pneumothorax | Detects visible pleural line and lung collapse |
| Rib fractures | Identifies cortical breaks or displacement |
Preparing for test
- Remove metal: necklaces, zippers, bras with underwire, piercings
- Change into gown: Front-open cotton gown provided at the center
- Pregnancy status: Tell the technician; extra shielding available
Pre-requisites Chest PA View X-Ray Scan

Procedure for Taking a Chest PA View X-Ray Scan
- Registration & consent form at front desk
- Change into gown and remove all metallic items
- Positioning: Stand upright, chest against detector, hands on hips
- Hold breath on technician’s cue; image captured in <1 second
- Dress & collect receipt—digital report emailed/printed within 30 minutes
Caution Before Taking the Test
- Declare pregnancy or breastfeeding
- Limit repeat scans—only when medically justified
- Inform about implants: pacemaker, sternal wires, or orthopedic hardware
Test Results
Results and Interpretations
| Parameter | Normal Range | Possible Abnormality | Next Step |
|---|---|---|---|
| Lung field clarity | Uniform black | Patchy opacity → pneumonia | Follow-up with physician |
| Cardiac size | CTR ≤0.5 | >0.5 → cardiomegaly | ECHO referral |
| Costophrenic angles | Sharp | Blunted → pleural effusion | Ultrasound chest |
| Diaphragm position | Right dome 1–2 cm higher | Flattened → hyperinflation | PFT test |
| Bony thorax | Smooth cortex | Fracture line → trauma | Orthopedic consult |
Risks & Limitations
- Radiation Exposure: ~0.1 mSv—equivalent to 10 days of natural background radiation.
- Small Nodules: Lesions <5 mm may be missed; low-dose CT is better for screening.
- Pregnancy: Inform staff; lead shielding or alternative imaging may be advised.
