Hi, I am Dr. Atul Kumar Nimawat MS ENT
Computed tomography (CT) scans use X-ray radiation to create detailed cross-sectional images. A single head CT (including paranasal sinuses and brain) typically delivers 2–4 mSv of radiation, while a neck CT adds another 2–6 mSv. These doses are well below levels that cause acute tissue injury.
Radiation Dose and Biological Effects:-
Deterministic effects (tissue reactions) require radiation doses hundreds of times higher than diagnostic CTs; you will not get mucosal injury (e.g., swelling, pain) from routine scans.
Stochastic effects (e.g., radiation-induced cancer) accrue over years and are not responsible for acute infections like tonsillitis or pharyngitis.
Tonsillitis & Pharyngitis: Likely Causes
Viral or bacterial infection (e.g., streptococcus, adenovirus)
Post-nasal drip or gastroesophageal reflux irritating the throat
Allergies or seasonal factors
Next Steps
Diagnostic Approach
Clinical examination by ENT
Throat swab/culture if bacterial infection is suspected
Blood tests (e.g., CBC, CRP) to assess inflammation
Fiberoptic laryngoscopy if recurrent or severe
Health Tips
Limit unnecessary scans: Discuss with your physician if repeat imaging is essential
Maintain throat hygiene: Frequent hand-washing, avoid irritants (smoke, dry air)
Follow-up: If symptoms persist >2 weeks or worsen (difficulty breathing/swallowing), return to ENT OPD.
