CT Lower Neck & Thorax

Definition and imaging technology

A CT LOWER NECK & THORAX scan uses X-rays and advanced detectors to create cross-sectional images from the collarbone to the top of the lungs. Our spiral CT rotates continuously, capturing data in a single breath-hold.

How annotated scrollable images enhance diagnosis

Cadabams Diagnostics overlays color-coded labels onto the 3D reconstruction. Radiologists can scroll through layers, zoom into suspicious areas, and share interactive links with your doctor for faster, more precise treatment planning.

Contrast-enhanced vs non-contrast

• Non-contrast: Quick, ideal for stones or trauma
• Contrast-enhanced: Highlights vessels, lymph nodes, and tumors

Spiral vs multi-slice CT

• Spiral (helical): Continuous motion, ultra-fast
• Multi-slice: Up to 128 detectors for razor-thin slices (0.625 mm)

• Soft-tissue windows – evaluate thyroid, lymph nodes
• Bone window settings – detect fractures or spine involvement
• Lymph node zones – Level I–VII mapping for staging
• Vascular anatomy – carotid and subclavian arteries

Trauma evaluation

CT LOWER NECK & THORAX rapidly identifies airway injury, vertebral fractures, or vessel tears.

Infection or swelling

Detect abscesses, cellulitis, or retropharyngeal spread.

Tumour staging

Precisely measure tumor size and nodal involvement before surgery or chemo-radiation.

Common symptoms that prompt a scan

• Persistent neck pain or swelling
• Hoarseness lasting >3 weeks
• Difficulty swallowing or breathing
• Unexplained weight loss with night sweats

Referring specialists

• ENT surgeons
• Oncologists
• Endocrinologists
• Spine specialists

• High-resolution images down to 0.5 mm
• Quick scan time—less than 30 seconds on the table
• Scrollable 3D reconstruction for multi-angle review
• Same-day digital report accessible on the Cadabams app

• Thyroid nodules – benign vs malignant characterization
• Lymphadenopathy – infection or lymphoma staging
• Spine involvement in neck – disc herniation or metastasis
• Parathyroid adenomas – small lesions often missed on ultrasound

Diet and fasting

• With contrast: Fast 4 hours prior
• Without contrast: No fasting needed

Clothing and metal objects

• Wear loose cotton clothes; remove necklaces, earrings, and piercings.

Contrast preparation

• Drink 1 L water the day before to stay hydrated.
• Inform staff of previous contrast allergies.

• Doctor’s prescription – mandatory for scheduling
• Kidney function tests – serum creatinine & eGFR within 30 days for contrast studies

• Morning slots preferred for diabetic patients after overnight fast.
• Emergency cases accepted 24×7; priority reporting in 60 minutes.

• Age groups: Safe for infants to geriatrics; paediatric protocols available.
• Pregnancy considerations: CT avoided in first trimester unless life-threatening; shielding provided in second & third trimesters.

Quick facts about the CT neck scan

• Duration: 5–10 minutes total
• Technology: 128-slice spiral CT with annotated scrollable images
• Radiation: Lowest-dose protocols approved by AERB
• Report turnaround: 6 hours for routine cases, 1 hour for emergencies

Why choose Cadabams Diagnostics

• AI-assisted reconstruction for crystal-clear details
• Comfortable wide-bore scanner—ideal for claustrophobic patients
• 24×7 booking via app or phone
• Transparent pricing with no hidden contrast fees

Positioning on the table

Lie supine with head in a soft cradle; neck slightly extended.

Breathing instructions

Hold breath for 10-second scans; gentle breathing allowed between passes.

Contrast injection process

IV line in the arm; contrast delivered over 20 seconds via automated injector.

Allergies to iodine

Pre-medication with steroids & antihistamines for prior mild reactions; severe allergy patients offered alternative MRI.

Claustrophobia tips

Open-bore design reduces anxiety; music or relative accompaniment allowed.

Diabetes medications

Metformin paused 48 hours post-contrast if eGFR < 45; resume after kidney function re-check

Radiation exposure

Effective dose ≈ 2–3 mSv—about 6 months of natural background radiation. Pediatric and low-dose protocols reduce exposure by up to 40 %.

Contrast dye considerations

• Rare allergic reactions (1 in 10,000)
• Temporary metallic taste or warm flush
• Kidney function assessment required if eGFR < 45
