A Thoracic Spine CT scan is an imaging test that allows the structures of the dorsal (thoracic) region of the spine to be seen in great detail – especially the vertebrae and joints. It is very useful in the assessment of thoracic back pain, trauma, degenerative changes, suspected fractures, and for surgical planning and post-operative follow-up.
What is a Thoracic Spine CT Scan and what is it for?
A Thoracic Spine CT scan is a computed tomography study focused on the thoracic vertebrae (T1 to T12) and adjacent structures. It allows accurate assessment of:
- Vertebrae and alignment;
- Facet joints (zygapophyseal joints) and bony structures;
- Changes that may contribute to nerve compression (for example, narrowing of the spinal canal or the neural foramina).
It is a particularly useful exam when a detailed assessment of bone is required (for example, when a fracture is suspected) and in evaluation before/after surgery.
What is the price of a Thoracic Spine CT Scan?
The private price of a Thoracic Spine CT scan is €120.
However, you may have a Thoracic Spine CT scan through several agreements, including:
- SNS / ARS: When the Thoracic Spine CT scan is performed through the SNS, the patient does not pay any amount (you must bring the prescription from the Health Centre);
- ADSE: If the Thoracic Spine CT scan is performed through ADSE, the patient only pays the fee of €16;
- IASFA, ADM GNR, SAD PSP;
- Insurance providers: Médis, Multicare, Advance Care, Allianz, Saúde Prime, Future HealthCare, SS CGD, SAMS Quadros, SAMS, Montepio, RNA, Generali, Mudum, MGEN, Aegon, Vitória, Una Seguros, other insurers. In this case, the price varies depending on the insurance you use;
- Health plans: Medicare, Saúde Prime, Future HealthCare, Continente Wells, ACP, other health plans. In this case, the price varies depending on the health plan you use;
- Protocols: NRD has protocols with several clinics and institutions that allow you to have the exam at very competitive rates. For the Thoracic Spine CT scan, the protocol price is €80.
How is it performed?
A Thoracic Spine CT scan is performed with the patient lying on a table (bed) that slides into the scanner. Thin slices of the thoracic segment are obtained and, in some cases, multiplanar and 3D reconstructions may be performed, which are useful for planning and post-operative assessment.
On average, the exam takes 10 to 20 minutes.
NRD has a latest-generation Philips 128-slice scanner, which provides sharp images with a low radiation dose, ensuring safety and effectiveness in every exam.
What does it detect?
A Thoracic Spine CT scan can help identify several changes, such as:
- Fractures, fissures and vertebral collapse;
- Degenerative changes, osteophytes and foraminal stenosis/spinal canal stenosis (“narrow canal”);
- Spondylolysis and alignment abnormalities;
- Bony changes associated with calcified disc herniations;
- Post-operative changes (for example, assessment of surgical hardware);
- Bone tumours and vertebral metastases;
- Signs of infection (for example, spondylodiscitis) and paravertebral changes / abscesses;
- Among others.
In which cases is it indicated?
A Thoracic Spine CT scan is generally recommended by the doctor in situations such as:
- Trauma with suspected fracture;
- Persistent thoracic back pain with red-flag signs;
- Surgical planning and post-operative follow-up;
- Assessment of spinal canal stenosis and radiculopathies (when applicable);
- Suspected tumours or vertebral infection (depending on the clinical scenario);
- Assessment of deformities and instability;
- Among others.
Thoracic Spine CT Scan with Contrast
In most cases, a Thoracic Spine CT scan is performed without contrast.
In selected situations (for example, suspected infection, tumours, or certain post-operative complications), iodinated intravenous contrast may be used.
The injection may cause a transient warm sensation or a metallic taste. When contrast is required, a 4-hour fast is generally requested (you will be informed at the time of booking).
Preparation for a Thoracic Spine CT Scan
| Topic | Guidance |
| Exam prescription (paper copy) | You must bring the exam prescription in paper format. |
| Fasting | With contrast: 4-hour fast. Without contrast: generally, fasting is not necessary. |
| Arriving early | Generally, you only need to arrive 15 minutes before the exam. |
| Previous exams | Bring any relevant previous exams, if you have them. |
| Medical history and medication | Inform the team about allergies, asthma/allergic disease, kidney disease, thyroid disease and your usual medication. |
| Metal objects | Remove metal objects in the area to be examined (for example, necklaces, piercings, hair clips, or clothing with metal). |
| Water | If needed or if you wish, you may drink water. |
NRD will provide you with all instructions at the time of booking.
Instructions during the exam
To ensure the best image quality and that the exam is completed quickly, it is important to:
- Remain still during image acquisition to avoid artefacts in the images;
- Follow the technologist’s instructions, who may ask for small position adjustments and, when necessary, to hold your breath for a few seconds.
When and how do you receive the results?
You will receive the CT results within up to 7 days after the exam, by email or on paper at the clinic. On the day of the exam, you will take the CD with the images with you.
Where to have it done?
The Thoracic Spine CT scan can be performed at NRD, at the following address:
Avenida Columbano Bordalo Pinheiro, nº 11-B, ground floor, 1070 – 060 Lisbon (near Praça de Espanha).
