CT Scan at Raffles Hospital

Advanced CT scanning at Raffles Hospital covering coronary calcium scoring, CT angiography, chest CT for lung cancer screening, abdominal CT, and targeted cancer surveillance. Reported by specialist radiologists and integrated with executive health screening packages.

Raffles Hospital's radiology department offers advanced Computed Tomography (CT) scanning as part of the Raffles Health Screeners programme. CT uses X-ray technology combined with computer processing to produce detailed cross-sectional images of the body in seconds, making it an indispensable tool for cardiac, thoracic, abdominal, and oncological screening. Coronary CT Calcium Scoring (CTCS) is one of the most requested preventive cardiology tests at Raffles. This non-contrast scan takes less than ten minutes and quantifies calcium deposits in the coronary arteries, producing an Agatston score that predicts 10-year cardiovascular event risk with high accuracy. Individuals with elevated scores benefit from early statin therapy, aspirin discussion, and lifestyle intervention — preventing heart attacks before they occur. Coronary CT Angiography (CCTA) uses contrast medium to visualise the coronary arteries directly, identifying soft plaque, stenosis, and vessel anomalies that CTCS alone cannot characterise. It is recommended for patients with intermediate calcium scores or atypical chest symptoms who wish to avoid invasive catheterisation. Low-dose CT chest scanning for lung cancer surveillance is indicated for current or former heavy smokers aged 50–80 and is one of the few imaging-based cancer screenings proven to reduce cancer mortality. The low-dose protocol minimises radiation exposure while maintaining diagnostic sensitivity for pulmonary nodules as small as a few millimetres. Abdominal and pelvic CT evaluates the liver, gallbladder, pancreas, kidneys, spleen, bowel, and pelvic organs for tumours, cysts, calculi, and structural abnormalities. CT colonography (virtual colonoscopy) is available as a non-invasive alternative to conventional colonoscopy for colorectal cancer surveillance in appropriate patients. All CT studies are performed on multi-detector scanners and reported by specialist radiologists within Raffles Hospital. Results are integrated into the health screening report and discussed with the patient in a physician consultation, ensuring findings are contextualised and acted upon promptly.
