Singapore: Medical Imaging Guidelines

1. Can I Walk In for Medical Imaging?

• Yes, but with limitations. Walk-in availability depends on the facility and imaging type.
• Public hospitals/polyclinics: Walk-ins are generally not allowed for advanced imaging (e.g., CT, MRI) due to high demand and scheduling. X-rays may be available at polyclinics with shorter wait times, but appointments are preferred.
• Private clinics/hospitals: Many private imaging centres (e.g LifeScan and AsiaMedic) allow walk-ins for X-rays and ultrasounds, subject to availability. For CT or MRI, appointments are strongly recommended due to equipment and technician scheduling.
• Radiology clinics: Standalone radiology centres (e.g., RadLink, AsiaMedic) may accept walk-ins for certain scans, but calling ahead is advised to confirm.
• Recommendation: Book an appointment to avoid long waits, especially for advanced imaging. Some clinics offer same-day or next-day slots.

2. How Long to Get Results?

1. General turnaround time:
   • X-ray/Ultrasound: Results are often available within 1–3 hours for urgent cases or same day to 1–2 days for non-urgent cases. If a radiologist’s report is needed, expect 1–3 days.
   • CT/MRI: Preliminary results may be available within a few hours for emergencies. Full reports typically take 1–5 days, depending on the complexity and whether a specialist review is required.
   • Private vs. Public: Private facilities often provide faster results (same day or next day) due to lower patient loads and streamlined processes. Public hospitals may take longer (up to a week for non-urgent cases).
   • Delivery: Results are usually sent to the referring doctor, or patients can collect them in person or via online portals (common in private clinics).

3. What Should I Do Before Medical Imaging?

• General Preparation:
  • Fasting: Required for certain scans (e.g., abdominal ultrasound or CT with contrast). Typically, no food or drink for 4–6 hours before the scan. Check with the facility.
  • Clothing: Wear loose, comfortable clothing without metal (e.g., zippers, jewelry) for X-rays and MRIs. You may need to change into a gown.
  • Medical history: Inform the clinic of allergies (especially to contrast dye), pregnancy, or conditions like kidney issues, as these affect contrast use.
  • Medications: Continue regular medications unless instructed otherwise. For MRI, disclose any implants (e.g., pacemakers) due to magnetic interference.
• Specific Scans:
  • X-ray: Minimal preparation; remove metal objects in the imaging area.
  • Ultrasound: May require a full bladder (drink water beforehand) for pelvic scans or fasting for abdominal scans.
  • CT/MRI: Contrast dye may be used; kidney function tests might be required beforehand for older patients or those with renal issues.
  • Check-in: Arrive 15–30 minutes early to complete registration and consent forms.

4. Do I Need to See a Doctor Before Medical Imaging?

• Yes, usually.
• Public sector: A doctor’s referral (from a polyclinic or hospital) is mandatory for all imaging in public facilities to ensure medical necessity and cost subsidies.
• Private sector: A referral is typically required for advanced imaging (CT, MRI) due to regulatory guidelines and insurance claims. For X-rays or ultrasounds, some private clinics allow direct access without a referral, but a consultation with the clinic’s doctor may still be needed.
• Exceptions: Health screening packages (e.g., at Thomson Medical) may include X-rays or ultrasounds without a prior doctor visit, but these are for preventive purposes, not diagnostics.
• Process: See a general practitioner (GP) or specialist who will assess your condition and issue a referral letter. For private clinics, some offer in-house consultations to streamline the process.
