PET/CT Scans in Johor Bahru: A Patient Guide
PET/CT combines molecular imaging with anatomical imaging. The radiotracer is selected according to the clinical question, allowing the scan to assess cancer biology, disease distribution and response to treatment.
New brain PET development
FDA approves an F-18 tau PET agent.
TAUKLARIFY (florquinitau F-18) is approved in the United States to identify tau neurofibrillary tangle pathology in adults being evaluated for Alzheimer’s disease.

- FDG PET/CT for many cancers and selected infection or inflammation indications.
- PSMA PET/CT for staging and restaging selected prostate cancers and assessing PSMA expression.
- Somatostatin-receptor PET/CT such as DOTATATE for selected neuroendocrine tumours.
- Specialist neurological or cardiac PET applications where clinically indicated.
What happens on the day?
After registration and clinical review, a small amount of radiotracer is administered. An uptake period follows before imaging. The scan itself is painless, but remaining still is important.
Preparation, uptake time and total appointment duration vary by tracer. Patients should bring relevant reports and imaging and inform the team about diabetes, medicines, pregnancy or breastfeeding.
How PET/CT supports precision care
PET/CT can help define the extent of disease, assess treatment response, investigate suspected recurrence and support selection for targeted therapies. Interpretation must integrate the scan pattern with clinical history, histology, laboratory results and other imaging.
Tunku Laksamana Johor Cancer Centre is developing molecular imaging capability in Johor Bahru. Service availability remains subject to facility completion, regulatory approvals, licensing and commissioning.
Preparing for a useful scan
- Confirm the tracer and preparation instructions with the imaging centre.
- Do not assume that fasting rules are identical for every type of PET scan.
- Bring previous PET/CT, CT, MRI and relevant pathology results where available.
- Follow post-scan hydration and radiation-safety advice provided by the department.
Frequently asked questions
Questions patients often ask
What is a PET/CT scan?
PET shows the biological distribution of a radiotracer while CT provides anatomical detail. Fusing both datasets can improve localisation and interpretation.
Are all PET tracers the same?
No. FDG evaluates glucose metabolism, PSMA tracers target prostate-cancer biology, and somatostatin-receptor tracers such as DOTATATE are used for selected neuroendocrine tumours.
Is PET/CT radiation safe?
PET/CT uses ionising radiation. The examination should be justified for the individual patient and optimised to obtain the required diagnostic information with appropriate exposure.
How should I prepare?
Preparation depends on the tracer and clinical question. FDG PET/CT commonly requires fasting and glucose assessment, while other tracers have different instructions. Follow the imaging centre’s instructions exactly.
