Reducing Radiation Dose on CT: How IMR Technology Ensures Safety
Learn how modern IMR (Iterative Model Reconstruction) technology on Philips CT scanners reduces radiation dose by up to 80% while providing crystal clear images.

Early detection is the most powerful tool in the fight against cancer. Patient survival rates depend heavily on the stage at which the tumor is discovered. Computed Tomography (CT) is a cornerstone of oncology screening, allowing specialists to detect lesions as small as 1 mm.
Why CT is Critical in Oncology
Many tumors develop silently, showing symptoms only at advanced stages. CT imaging provides high-speed, high-precision visualization that helps clinicians:
- Identify tumors at a curable stage;
- Evaluate the exact size and heterogeneous structure of a mass;
- Detect metastatic lesions in distant organs;
- Monitor the effectiveness of chemotherapy or radiation.
Who Should Undergo Regular Screening?
- Adults aged 35–40+ regardless of symptoms;
- Individuals with a family history of oncological diseases;
- Patients with known benign tumors that require monitoring;
- Active or former smokers (lung cancer screening);
- People exposed to occupational hazards or chronic stress.
How CT Screening is Performed
Most oncological CT scans require an intravenous contrast agent. Malignant cells typically accumulate contrast faster than healthy tissue, making them stand out clearly on the images. The procedure usually scans the chest, abdomen, and pelvis to ensure no lesions are missed.
Survival and Early Diagnosis (WHO Data)
- Stage I: Survival rate up to 93%;
- Stage II: Survival rate around 75%;
- Stage IV: Survival rate often falls below 45%.
At Brigid Medical Center, we use latest-generation Philips scanners to provide precise oncology screening with the lowest possible radiation dose.
