How can we help?
We've gathered here the answers to the questions we're asked most. Search by keyword or browse by topic — and if you can't find what you're looking for, get in touch.
Bookings and referral
Do I need a medical referral to have an exam?
Yes — diagnostic imaging exams require a valid medical referral. There are two dedicated routes: for preventive exams (imaging check-up) you do not need to bring a referral, because the indication is taken on by CRMA's medical team at the prior assessment; for interventional radiology, booking is by phone and preceded by an assessment by the medical team. Learn more under Prevention and Interventional Radiology.
How do I book an exam?
Through the online form, by phone (+351 289 892 100 — national landline call charge), by email (clinica@crmalgarve.pt) or in person at our reception, in Faro.
Is my online request confirmed straight away?
No. The request is not binding — CRMA's team will contact you during working hours to confirm the date, time and any preparation needed. Your booking is only final after this confirmation.
Can I cancel or reschedule my booking?
Yes — you can cancel or reschedule at no cost. We only ask that you let us know as far in advance as possible: the slot you free up can make all the difference to another patient waiting for an exam.
How much does an exam cost?
Prices are not listed on the website — they are given when your booking is confirmed, depending on the exam, the insurer or subsystem covering it and any preparation needed.
How do I know which exam is right for me?
The exam is determined by your doctor, who issues the referral. If you have questions after receiving the referral, we can help you clarify the practical aspects of the exam, but the clinical indication always rests with the referring doctor.
Is there a waiting list to book exams?
Most exams are scheduled quickly. Even so, some services may have longer waiting times — in that case you can ask to be placed on a waiting list and we will contact you as soon as a slot becomes available.
Insurance and cover
Do you work with my insurer or health subsystem?
We work with the SNS (convention) and with the country's main health insurers and subsystems — ADSE, Multicare, Médis, AdvanceCare and others. See the full list of agreements or contact us to confirm case by case.
What do I need to bring to use my agreement?
As a rule, your medical referral and the insurer or subsystem card. Some agreements require additional documents — this depends on the insurer or subsystem, and we let you know when your booking is confirmed.
How much will I pay with my agreement?
The amount depends on the terms of your insurer or subsystem and your plan, and also on the exam. It is communicated when your booking is confirmed, with no surprises on the day of the exam.
Preparation
Do I need to fast?
It depends on the exam. For example, for a CT scan with contrast the fasting period is 4 hours; many exams require no fasting at all. The specific instruction is on your exam's page and is always confirmed when you book.
Can I take my regular medication?
As a rule, keep taking all your regular medication, including metformin, unless your doctor advises otherwise. If in doubt, speak to us when you book.
What should I wear and bring on the day of the exam?
Comfortable clothing that is easy to take off and put on, preferably with no metal parts (zips, metal buttons). Bring your referral, the card of the insurer or subsystem covering the exam, and your previous examinations.
Should I bring previous examinations?
Yes, whenever possible. Bringing previous studies (reports and/or images) helps the radiologist make comparisons. You can bring them on CD, in digital format or on paper.
Do I need to arrive earlier?
For some exams, yes — for example, when oral contrast or hydration has to be done at the clinic, you may need to arrive 30 to 60 minutes early. The exact instruction is given when your booking is confirmed and is on each exam's page.
During the exam
Are CT and CAT scans the same thing?
Yes. CT (computed tomography) and CAT (computed axial tomography) refer to the same exam — 'CAT scan' is the older term and 'CT scan' is the current one. At CRMA you may see both: the exam is exactly the same.
Is the radiation from a CT scan dangerous?
A CT scan uses X-rays. At CRMA, protocols are adjusted to use the lowest dose needed for diagnostic quality, on a recent 128-slice scanner. The exam is carried out when the clinical benefit justifies the exposure.
Does magnetic resonance imaging involve radiation?
No. MRI uses a magnetic field and radio waves — it does not use ionising radiation (X-rays).
I'm allergic to contrast. Can I still have the exam?
Let us know when you book. Each case is assessed individually by the radiologist — depending on the clinical context, an exam without contrast, pre-medication or another modality may be chosen.
I have claustrophobia. Can I have the MRI scan?
Many people with mild claustrophobia have the exam with support from our team — and for several exams the head can stay outside the tunnel. If you feel very anxious, contact the clinic before the day of the exam so we can find the most suitable solution together.
I'm pregnant. Can I have imaging exams?
Always tell us if pregnancy is confirmed or possible. Ultrasound is considered safe. MRI does not use ionising radiation and may be performed at any stage of pregnancy when the doctor considers the information necessary — in the first trimester, as a precaution, the indication is weighed case by case. For exams using X-rays (X-ray, CT, mammography), whether to proceed is assessed case by case by the radiologist, according to the clinical benefit.
Can I breastfeed after an exam with contrast?
Yes. Current recommendations (ACR/ESUR/EMA) indicate that breastfeeding may continue as normal, both after contrast (CT) and after a Group II macrocyclic gadolinium agent (MRI), with no need to interrupt it.
Why do I have to give consent for an exam that uses radiation?
Informed consent is a legal and ethical requirement. It ensures that you understand the aims, benefits and risks of an exam that uses ionising radiation (such as X-ray or CT) before you have it. Our team is happy to answer any questions.
Safety Questionnaire
What is the Safety Questionnaire?
It is a form that collects information essential to your safety before the exam — implants and medical devices, allergies, pregnancy, illnesses and medication. It allows the team to prepare the exam safely and without delays.
When and how should I fill it in?
Preferably before the day of the exam, online. If you can't, reception will help you fill it in when you arrive.
Why is it so important for magnetic resonance imaging?
Because MRI uses a strong magnetic field: devices such as pacemakers, neurostimulators, clips or metal fragments can contraindicate the exam or require special care. That is why the questions about implants are mandatory before any MRI.
Why do I fill in the questionnaire every time I come to the clinic?
Because it is reviewed for each exam, for safety: information such as medical history, allergies, medication or other conditions can change over time and affect the exam. Confirming it ensures your safety and the quality of the procedure.
Results and timeframes
When will my results be ready?
The timeframe varies with the type of exam and is given to you at the end of the exam.
How do I receive my results?
The report, produced by a radiologist, is made available as a PDF (by email or printed) and the images on CD and on CRMA's imaging platform (imagiologia.abneves.pt), to take to your doctor. Your platform access details are given to you when you register.
Are the results sent to my doctor?
With your written authorisation, we can send the report directly to the referring doctor.
Can someone else collect my results?
Yes, with your authorisation.

Do I need to show ID, even with the collection slip?
Yes. We always confirm identity for reasons of security and protection of your health data — this is what safeguards the confidentiality of clinical information.
I have a booked exam. Does priority service apply?
As a rule, priority service does not apply to pre-booked exams: these are seen at the booked time or in order of arrival. There are, however, exceptions linked to clinical assessment and the patient's state of health.
Is there parking near the clinic? Is it paid?
There is paid public parking on the nearby streets and free parking at Largo de São Francisco, about 200 metres away (2–3 minutes on foot).
