Computed Tomography (CT) Scan
What is Computed Tomography(CT) Scan?
Computed Tomography (CT) Scan is a medical imaging technique that uses X‑ray beams rotating around the target organ to create detailed cross‑sectional images for examining internal structures. Compared with plain X‑rays, CT produces higher‑resolution, three‑dimensional images with lower radiation. As a result, CT scans are now a common choice for diagnosing brain, cardiac and vascular imaging, the lungs/chest, abdomen, and the urinary system.
BNS Medical Imaging use the GE Revolution CT, which offers advantages such as ultra-fast scanning, low radiation exposure, and high-resolution 3D imaging. It minimizes patient wait times and motion artifacts, while providing clear and detailed three-dimensional images for accurate diagnosis. Central Branch provide CT scans located near Exit B of Central Station or Exit C of Hong Kong Station. With a comfortable environment and friendly service, patients can undergo examinations with peace of mind.

What is CT Scan used for?
In most cases, you'll need a referral from your doctor to schedule a CT Scan. The following are common indications for the examination:
Heart and Coronary Arteries
Assess coronary calcium, detect coronary stenosis or occlusion, identify cardiac structural abnormalities, and evaluate anatomy before coronary surgery or interventions.
Head & Neck
Assess intracranial hemorrhage, skull fractures, brain lesions or infection, and evaluate neck lymph nodes, masses, vascular issues (e.g., carotid stenosis, aneurysm) and airway/pharyngeal abnormalities.
Body
Assess chest and lung conditions, abdominal and pelvic tumors or inflammation, and urinary issues such as kidney stones or urinary obstruction.
Vascular Studies
Assess aneurysms, vascular stenosis, or thrombosis.
Preparation and Process
Preparation before the examination:
- Please bring the latest relevant medical reports and old firms for comparison (e.g., X-rays, MRI , CT scans, etc.).
- Please notify our staff if you are pregnant or suspected you are pregnant.
Before the Examination:
The patient will lie on the scanning bed, which will then slowly move into the circular opening of the scanner to conduct the scan.
During the Examination:
During the scan, the patient should avoid any movement.
After the Examination:
- After the examination, the patient can leave once the staff confirms there are no discomforts or allergic reactions.
- If the patient experiences any discomfort during or after the examination, such as difficulty breathing, they should immediately notify the medical staff.
FAQs in CT Scan
What is CT Scan?
Computed tomography (CT) is an imaging technique that uses X‑rays and computer reconstruction to produce cross‑sectional or three‑dimensional images of the body's internal structures. It is used to diagnose trauma, tumors, organ inflammation, vascular disease, and more.
Do I need to receive a contrast injection?
Certain exams, like abdomen scans and angiography, require CT contrast for better diagnosis. If an injection is needed, please inform us of any iodine allergies, kidney issues, or medications you're taking. You may need to fast before a CT scan and have blood tests to check kidney function (eGFR/creatinine).
How should I prepare before the scan? Do I need to fast or stop medications?
Preparation depends on the type of scan: some require fasting (usually 4–6 hours). If you take diabetes medications or blood thinners, follow your doctor's instructions about whether to pause them.
Who processes the scan results?
The report is processed by a radiologist.
