Positron Emission Tomography–Computed Tomography

Positron Emission Tomography–Computed Tomography (PET-CT)

Low Radiation ・ More Efficient ・ High Resolution

The PET-CT scanner in Union Hospital can simultaneously detect organ function and cellular changes. PET-CT is especially valuable in the early detection of cancer and in monitoring treatment response, as changes in cellular metabolism often occur before they can be observed through standard physical examination.

Applications of PET‑CT

PET-CT is an imaging technology that combines functional and structural information. It is commonly used in cancer and brain examinations, and helps in the early detection of various diseases.

Cancer Screening: Early detection, staging, monitoring treatment effectiveness, and recurrence surveillance.
Brain Disorders: Assists in diagnosing dementia, localizing epilepsy, and Parkinson’s disease.
Other Uses: Locating infections, inflammations, and specific tumors.

Key Features

High-definition Imaging: Advanced technologies (Time-of-Flight and Q.Clear) deliver sharper, clearer images with enhanced detail. Q.Static further reduces motion artefacts, ensuring superior image quality.
Efficient Examinations: Routine scans can be completed up to 50% faster, or with radiation dose reduced by half.
Versatile Applications: Suitable for cancer detection, prostate health, neurological and brain evaluations. Provides reliable imaging for both early diagnosis and ongoing monitoring.
Spacious Design: A 70 cm wide bore enhances patient comfort and helps reduce anxiety.
Safer For Regular Follow-ups: Radiation dose reduced by half, making it particularly suitable for patients requiring repeated examinations.

PET-CT Examination Process

Before the scan: Patients should fast for 4hours, avoiding sugar and caffeine. Clinical staff will check blood glucose levels and review medical history.
Injection of tracer: A small amount of radioactive tracer is administered. It circulates through the bloodstream and is absorbed by the body over approximately 45–60 minutes.
Imaging: The patient lies still on the scanning bed while images are acquired. The process takes around 20–30 minutes.
After the scan: The images are analysed by a radiologist, who prepares a report. The referring doctor will then explain the findings to the patient.
