QUESTIONS TO ASK
BEFORE HIFU
HIFU eligibility is not simply about your tumour type — it is about whether your specific anatomy provides a usable acoustic window and whether the centre you are considering has adequate experience with your exact indication and lesion location. These questions help you determine both.

Why Pre-HIFU Questions Are Different from Other Ablation
For percutaneous ablation, the core questions focus on tumour size, vessel proximity, and complication risk. For HIFU, one additional dimension must be verified before any of those matter: does your tumour have an accessible acoustic window? Without a clear acoustic path, HIFU cannot reach the target regardless of how otherwise suitable the case is.
“An interventional oncologist who can describe your specific acoustic window — not just that HIFU is possible 'in general' for your tumour type — is an operator who has actually reviewed your imaging.”
HIFU-Specific: Always Ask About the Acoustic Window
Before any other clinical discussion, confirm that the treating operator has reviewed your actual CT or MRI — not just your diagnosis — and has specifically assessed whether your tumour's location provides a clear acoustic path from the planned transducer position. This question separates operators who have genuinely reviewed your case from those offering a generic eligibility assurance.
System Selection: Not All HIFU Is the Same
USgHIFU and MRgFUS are different tools. Asking which system will be used for your case — and why that system is preferred over the alternative for your specific anatomy — confirms that the treating team is making an active clinical decision rather than defaulting to whichever system the centre has installed.
Questions About Acoustic Window and Eligibility
These questions must be answered specifically for your anatomy — not with a generic 'yes, HIFU works for your tumour type' response.
| Question to Ask | What a Good Answer Looks Like |
|---|---|
| Have you reviewed my CT or MRI specifically for acoustic window feasibility — not just my diagnosis? | Direct confirmation that the operator has reviewed your imaging for beam path anatomy, not just your tumour type and staging report. |
| What structures lie between your transducer and my tumour, and are any of them obstacles? | A specific description of the acoustic path — rib positions, bowel proximity, surgical clips — and how each will be managed or whether preparation is required. |
| If my acoustic window is limited by bowel gas or ribs, what preparation will you use to resolve it? | A specific preparation plan — dietary restriction, water loading, positioning protocol — not a general reassurance that 'we deal with these things.' |
| What happens if the planning scan on the treatment day shows the acoustic window is not adequate? | A clear answer: session deferred; alternative approach offered; no treatment without adequate window — not 'we'll see on the day.' |
| Will you use USgHIFU or MRgFUS for my case, and why is that system preferable for my specific anatomy? | A system-specific rationale tied to your tumour location, proximity to critical structures, and monitoring requirements. |
Questions About Operator Experience and Centre Volume
HIFU outcome quality is strongly correlated with operator and centre volume for each indication. Ask these questions directly.
| Question to Ask | What a Good Answer Looks Like |
|---|---|
| How many HIFU procedures do you perform per year for my specific indication? | A specific number — at least 50/year for common indications (fibroids, bone metastases); higher for oncology indications. |
| Have you personally treated tumours in exactly this location — adjacent to this vessel / behind this rib? | Direct confirmation with specific case experience — not a reference to the centre's general capabilities. |
| What is your centre's non-perfused volume (NPV) rate or technical success rate for this indication? | A specific percentage or reference to a published series — 'good results' is not a quantified answer. |
| Who will perform my procedure — the consultant I am meeting, or a trainee under supervision? | Explicit confirmation that the consultant will perform or directly supervise all critical sonication decisions. |
| What is your complication rate for this indication, and what are the most common complications you have encountered? | A specific rate with honest disclosure of the most frequent adverse events — not only the best-case scenario. |
Questions About the Procedure and What to Expect
These questions ensure you understand what will happen during treatment and what you are committing to across all sessions.
- 1
How many sessions will I need, and how do you decide that?
The answer should reference your tumour size, depth, and the volume achievable per session. 'One session' for a large or deep tumour is a red flag; an honest session estimate requires case-specific planning.
- 2
What will I feel during the treatment session?
A specific description of expected sensations — warmth, pressure, aching — and how sedation will be used to manage them. Sharp pain during HIFU is a safety signal; ask what happens if you feel it.
- 3
What cooling protection is used for my skin?
For USgHIFU: the water bath provides cooling — confirm the system has active temperature monitoring of the water and the skin surface. For MRgFUS: a water circulation membrane should maintain skin below 40°C throughout.
- 4
What does the post-treatment imaging show on the same day?
Confirm that a same-day or next-day contrast-enhanced MRI or CEUS will assess the non-perfused volume before you are discharged. You should not leave the centre without an objective same-day assessment of whether the treatment achieved its goal.
- 5
How long do I need to stay in China/India before I can safely travel home?
For uncomplicated HIFU, most patients can travel within 24–48 hours. The specific minimum depends on the organ treated and any immediate post-procedure observations required.
Questions About Incomplete Ablation and Follow-Up
These questions define what happens after the procedure — and what the plan is if the treatment is not fully successful.
| Question to Ask | Why It Matters |
|---|---|
| What NPV ratio do you aim for, and what happens if the same-day imaging shows incomplete ablation? | Confirms the centre has a defined technical success criterion and a clear protocol for residual viable tumour — not just 'we'll reassess at follow-up.' |
| If I need an additional session, how soon after the first can it be done, and will the cost be covered? | Session 2 or 3 costs should be established upfront — unexpected additional costs after you have already travelled are a significant practical concern. |
| What is the follow-up imaging schedule after I return home, and who interprets the scans? | A specific timeline (4–6 weeks, 3 months, 6 months) and confirmation that the treating centre can review follow-up imaging remotely — not just hand you a calendar and wish you well. |
| Can my home oncologist receive the procedure report and follow-up assessments in English? | Continuity with your home team depends on this — confirm the centre can provide translated reports or that your navigator (CancerFax) handles this translation and forwarding. |
| How do I reach your team urgently if I have concerns after returning to my home country? | Direct contact details for the treating HIFU specialist or a named coordinator — not a general hospital telephone number — should be provided at discharge. |

Frequently Asked Questions
Common questions from patients preparing for their first HIFU consultation.
Getting Ready for Your Consultation
What documents should I have ready before a HIFU consultation?
Bring or have available: your most recent CT and/or MRI on digital media (CD or cloud link) — the radiological images, not just the written report; pathology or biopsy reports confirming the diagnosis; CA 19-9 or AFP if applicable to your tumour type; a list of current medications; and a brief written summary of your treatment history. For HIFU specifically, a recent (within 6 weeks) cross-sectional scan is essential for acoustic window assessment — older imaging may not reflect current tumour or anatomy. If working through CancerFax, our team prepares a structured case summary from all these documents before your consultation.
Should I get a second opinion before agreeing to HIFU?
For most oncology HIFU indications — liver, pancreatic, bone metastases — a second opinion confirming HIFU is appropriate and technically feasible for your specific tumour is entirely reasonable. Western oncologists may not be familiar with USgHIFU in oncological settings; CancerFax can arrange a remote specialist second-opinion consultation with a senior Chinese HIFU oncologist who can review your imaging and provide a written eligibility assessment within 7–10 working days. This is particularly valuable if your home team is uncertain about HIFU but has not specifically assessed your acoustic window.
Is it appropriate to ask about the operator's complication history?
Absolutely — and experienced HIFU operators expect and welcome this question. Asking 'what is your complication rate for this indication?' is not impolite; it is responsible. A centre or operator who deflects this question or provides only vague reassurances should be approached with caution. At specialist centres accessible through CancerFax, we have already verified operator volume and complication rates before making a referral — and we share this information transparently with patients as part of the decision-making process.
