HRCT Chest / Temporal Bone (Cochlear Imaging )/PNS

HRCT is an advanced CT scanning technique that produces extremely detailed, high-resolution images of small anatomical structures.

  • HRCT Chest focuses on the lungs and airways, offering clear visualization of lung parenchyma, bronchi, and pleura.

  • Temporal Bone (Cochlear Imaging) is used to examine the delicate bones and cochlear structures of the ear, crucial for hearing-related assessments.

  • PNS (Paranasal Sinuses) Scan evaluates the sinuses for inflammation, infection, blockages, or other abnormalities.

we offer advanced HRCT (High-Resolution Computed Tomography) scans, including HRCT Chest, Temporal Bone (Cochlear Imaging), and PNS (Paranasal Sinuses). These specialized imaging techniques help diagnose a wide range of conditions with high precision, enabling early and accurate treatment planning.

Types of HRCT Scans Offered

  • HRCT Chest – Evaluates lung diseases like interstitial lung disease, pulmonary fibrosis, bronchiectasis, and infections.

  • HRCT Temporal Bone / Cochlear Imaging – Assesses middle and inner ear structures, cochlear implants, congenital ear abnormalities, and hearing loss causes.

  • HRCT PNS (Paranasal Sinuses) – Checks for sinusitis, nasal polyps, anatomical variations, and chronic sinus disease.

Common Uses of the Procedure

  • Detecting lung diseases, infections, or fibrosis (HRCT Chest)

  • Evaluating hearing loss, middle/inner ear disorders, or cochlear implant planning (Temporal Bone Imaging)

  • Diagnosing chronic sinusitis, sinus tumors, or nasal blockages (PNS Scan)

  • Assessing trauma, congenital anomalies, or pre-surgical planning for ear or sinus surgeries

How Do I Prepare for My HRCT Scan?

  • Usually, no special preparation is needed.

  • Wear comfortable, loose-fitting clothes; you may be asked to change into a gown.

  • Remove metal objects like jewelry, glasses, or hearing aids before the scan.

  • If contrast dye is used (rare for these scans), you may need to fast for a few hours.

  • Inform the technologist if you are pregnant, have allergies, or have kidney problems.

What Will Happen During My HRCT Scan?

  • You will lie on a movable table that slides into the CT scanner.

  • The technologist will position you comfortably and may provide pillows or supports.

  • The scanner will rotate around the targeted area (chest, temporal bone, or sinuses) to capture precise images.

  • You may be asked to hold your breath briefly during chest scans to avoid motion artifacts.

  • The procedure is quick—usually 10–20 minutes—and is completely painless.

Reasons for an HRCT Chest / Temporal Bone / PNS Scan

  • Persistent cough, shortness of breath, or unexplained chest symptoms (HRCT Chest)

  • Hearing loss, ear discharge, chronic ear infections, or pre-cochlear implant evaluation (Temporal Bone)

  • Chronic nasal congestion, facial pain, sinus headaches, or suspected sinus disease (PNS)

Why Skeletal and HRCT Imaging is Used

  • Skeletal CT: For detailed evaluation of bones, fractures, trauma, infections, or bone tumors.

  • HRCT Chest / Temporal Bone / PNS: For superior soft tissue and bone interface resolution, helping in early detection and precise treatment planning in lung, ear, and sinus conditions.
