By Assoc. Prof. Dr. Hanani Abdul Manan<\/strong><\/p>\n\n\n\n

Many patients feel anxious when a doctor recommends a CT (Computed Tomography) scan, particularly when the examination involves sensitive areas such as the brain or abdomen. This concern is understandable, as the term radiation<\/em> is often associated with potential health risks.<\/p>\n\n\n\n

However, modern CT technology has advanced significantly over the past decade. Current scanners are much safer than earlier generations, with radiation doses greatly reduced through technological improvements and strict safety protocols.<\/p>\n\n\n\n

In addition, medical imaging practices follow the ALARA principle (As Low As Reasonably Achievable), which ensures that radiation exposure is kept to the minimum level necessary while still producing high-quality diagnostic images.<\/p>\n\n\n\n

Protective equipment also plays an important role in radiation safety. As shown in the figure, lead aprons are available near the CT technical room and are used to protect medical staff and patients from unnecessary radiation exposure when required.<\/p>\n\n\n\n

These safety measures, together with improved imaging technology, help ensure that CT scans remain one of the most valuable and reliable diagnostic tools in modern healthcare while maintaining patient safety.<\/p>\n\n\n\n

A CT scan uses X-rays taken from multiple angles around the body to produce detailed cross-sectional images of internal structures. These images are then reconstructed into three-dimensional views, allowing doctors to examine organs such as the brain, lungs, liver, and intestines with remarkable clarity.<\/p>\n\n\n\n

This level of detail enables physicians to quickly detect conditions such as internal bleeding, infections, tumours, fractures, or internal injuries. In emergency situations, CT imaging can be life-saving, enabling rapid diagnosis and immediate treatment decisions.<\/p>\n\n\n\n

Although CT scans involve ionising radiation, their use is carefully controlled. Each scan is performed only when the expected medical benefits clearly outweigh the potential risks.<\/p>\n\n\n\n

ADVANCES IN CT TECHNOLOGY<\/strong><\/p>\n\n\n\n

Radiation doses from CT scans have changed dramatically over the past 10 to 15 years.<\/p>\n\n\n\n

Earlier CT systems, such as 16-slice and 64-slice scanners, represented major technological milestones in radiology at the time. However, these systems lacked many of the advanced dose-reduction features available today. As a result, patients were exposed to higher radiation levels to obtain high-quality diagnostic images.<\/p>\n\n\n\n

Modern CT scanners, including 128-slice, 256-slice, and even 640-slice systems, now incorporate a range of intelligent technologies designed to minimise radiation exposure while maintaining excellent image quality.<\/p>\n\n\n\n

One key innovation is Automatic Exposure Control (AEC). This system automatically adjusts the X-ray output according to the patient\u2019s body size and shape, ensuring that each individual receives a radiation dose tailored to their specific anatomy.<\/p>\n\n\n\n

Another important advancement is Iterative Reconstruction, an image-processing technique that produces clearer images even when lower radiation doses are used. By reducing image noise and improving contrast, this technology allows accurate diagnosis while minimising radiation exposure.<\/p>\n\n\n\n

In addition, modern CT systems often include Organ-Based Dose Modulation, which provides extra protection to radiation-sensitive organs such as the eyes, thyroid gland, and breast tissue. These organs are particularly sensitive to radiation, even at relatively low doses.<\/p>\n\n\n\n

Many scanners also feature real-time dose monitoring, enabling radiographers to continuously assess radiation exposure during the scan and make adjustments when necessary.<\/p>\n\n\n\n

Thanks to these technological improvements, radiation doses for common examinations such as brain and abdominal CT scans have been reduced by approximately 50\u201380 percent compared with a decade ago.<\/p>\n\n\n\n

UNDERSTANDING RADIATION EXPOSURE<\/strong><\/p>\n\n\n\n

Radiation exposure from CT scans is often misunderstood because people rarely realise that radiation is already present in everyday life.<\/p>\n\n\n\n

Humans are constantly exposed to natural background radiation, which originates from sources such as cosmic rays, soil, food, and even the air we breathe. On average, individuals receive approximately 2 to 3 millisieverts (mSv) of natural radiation per year, depending on their geographical location and lifestyle.<\/p>\n\n\n\n

When compared with these natural levels, the radiation dose from a CT scan is relatively modest.<\/p>\n\n\n\n

Certain everyday activities can also slightly increase radiation exposure. For example, a long-distance flight from Kuala Lumpur to London exposes passengers to approximately 0.05 mSv due to increased cosmic radiation at high altitude.<\/p>\n\n\n\n

Similarly, individuals living in highland areas may receive slightly higher natural radiation levels because thinner atmospheric layers provide less shielding from cosmic rays.<\/p>\n\n\n\n

Understanding this context helps place CT radiation exposure into perspective. The additional radiation from a medically justified CT scan is relatively small compared with the natural radiation humans experience throughout their lives.<\/p>\n\n\n\n

RISKS AND MEDICAL NEEDS<\/strong><\/p>\n\n\n\n

The health risk associated with a single CT scan is extremely small. For adults, the estimated risk is less than 0.05 percent.<\/strong><\/p>\n\n\n\n

In contrast, failing to perform a CT scan when medically required can have far greater consequences. Conditions such as stroke, brain haemorrhage, internal bleeding, or ruptured appendix require rapid and accurate diagnosis. CT imaging often provides the fastest and most reliable means of identifying these life-threatening conditions.<\/p>\n\n\n\n

For this reason, CT examinations are carefully justified before being performed, and each scan must be approved by a qualified radiologist.<\/p>\n\n\n\n

Meanwhile, children are generally more sensitive to radiation than adults because their tissues are still developing and they have a longer lifespan during which potential radiation effects could occur.<\/p>\n\n\n\n

To address this, hospitals implement specialised paediatric CT protocols that significantly reduce radiation exposure. In many cases, doses for children can be reduced by up to 80 percent compared with adult protocols, while still maintaining diagnostic image quality.<\/p>\n\n\n\n

Whenever possible, doctors may also consider alternative imaging methods that do not involve radiation, such as ultrasound or magnetic resonance imaging (MRI).<\/p>\n\n\n\n

These careful approaches ensure that CT imaging remains safe even for younger patients.<\/p>\n\n\n\n

For patients who require repeated imaging such as those undergoing cancer monitoring or managing chronic diseases many medical centres now implement low-dose CT protocols specifically designed for follow-up examinations.<\/p>\n\n\n\n

These protocols ensure that cumulative radiation exposure remains as low as possible while maintaining high standards of diagnostic accuracy.<\/p>\n\n\n\n

This approach reflects the ongoing commitment within modern radiology to prioritise patient safety while delivering effective medical care.<\/p>\n\n\n\n

HARNESSING AI IN CT IMAGING<\/strong><\/p>\n\n\n\n

Artificial intelligence (AI) is increasingly transforming medical imaging. In modern CT systems, AI-based algorithms can automatically adjust scanning parameters based on the patient\u2019s body size, shape, and anatomical characteristics.<\/p>\n\n\n\n

This enables CT scanners to deliver the lowest radiation dose necessary for accurate diagnosis, while maintaining high-quality images.<\/p>\n\n\n\n

Emerging technologies such as Spectral CT and Photon-Counting CT are also improving the way CT images are produced. These technologies can differentiate between different X-ray energy levels absorbed by body tissues, generating images with greater detail and improved contrast.<\/p>\n\n\n\n

As a result, doctors can obtain more precise diagnostic information while keeping radiation exposure even lower than before.<\/p>\n\n\n\n

CT technology today is significantly safer than it was a decade ago. Advances in imaging technology, combined with intelligent dose-control systems and artificial intelligence, have dramatically reduced radiation exposure while improving image quality and diagnostic accuracy.<\/p>\n\n\n\n

When CT scans are performed under the supervision of trained radiologists and in accordance with the ALARA principle, they remain a safe and highly valuable medical tool.<\/p>\n\n\n\n

Rather than fearing radiation, it is important to understand its role in modern medicine. When used responsibly, radiation becomes a powerful diagnostic resource that helps doctors detect disease early, guide treatment decisions, and ultimately save lives.<\/p>\n\n\n\n

From identifying stroke within minutes to determining the cause of severe abdominal pain, CT scans serve as the \u201ceyes\u201d of modern medicine. With continuing technological advancements, CT imaging will remain an essential and increasingly safe component of healthcare in the years ahead.<\/p>\n\n\n\n
