PET/CT Second Opinion

Expert opinion and online consultations available on your computer or any mobile device. The service is available wherever there is an internet. All you need is a PC or a smartphone.

PET/CT combines two types of radiological diagnostics. Computed tomography produces high-resolution images of cross-sections of the body. Based on these, the radiologist assesses the anatomy of the body, identifies changes in the organs, and determines their nature.  At the same time, positron emission tomography technology can be used to draw conclusions about certain metabolic processes in the tissues.

Before a PET study, the patient is injected intravenously with a radiopharmaceutical. This is a low-radioactive substance that is distributed throughout the body. It almost never causes allergic reactions. The natural decay of this substance produces low radiation, which allows the doctor to visualize its distribution in the body. With the help of computed tomography, which is performed simultaneously, these metabolic processes can be accurately attributed to specific parts of the body.

The most commonly used PET/CT radiotracer is 18F-FDG, a glucose analog with the positron-emitting radionuclide fluorine-18, which displays cell metabolism. Since many tumor cells have an increased metabolism (e.g., due to their rapid growth), the radiopharmaceutical allows them to be detected.

In other words, it is PET/CT that can simultaneously answer two fundamentally different but very important questions:

- "What does the tissue look like?"

- "What are its biochemical properties?"

It can help, for example, to assess the effectiveness of chemotherapy for malignant diseases. Very often, metabolic changes in tumor foci become visible on PET/CT long before the mass actually shrinks in size. Because chemotherapy disrupts the metabolism of tumor cells, they absorb less radioactively marked glucose. Therefore, the doctor can determine early enough whether chemotherapy is the right choice or whether the treatment plan needs to be changed.

What is the service about?

A second opinion on PET/CT is a service which makes it possible to get a remote consultation of a qualified specialist, based on available radiology study results.

It might be helpful:

• to confirm the existing diagnosis;

• to verify the initial interpretation of imaging exams;

• to obtain a more detailed description of PET/CT scans;

• to get expert commentary on previously performed exam results;

• to make the right choice if there are two or more possible therapeutic options.

A written PET/CT  report including comments on the imaging quality and informative value, the detailed description of findings,  conclusions in regard to the possible nature of the identified suspicious areas, tumors and other abnormalities, the progress assessment (if the previous study was provided for comparison) and specific recommendations for further course of action (further or follow-up examinations).

What data should be provided to get a second opinion?

Written reports:

  • Treating physician's report (preferable)
  • A description of the CT imaging to be assessed (preferable)

Radiology data:

  • CT scan (requred)

What are the second opinion formats and terms?

Written second opinion:

  • a CT interpretation with conclusions and recommendations of further procedure. Report size: up to 1 page.

Video consultation:

  • All services contained in the written second opinion plus an up to 15-minute video conference with the radiologist in which the consulting expert comments on the imaging, explains the conclusions, discusses the recommended plan and answers the patient's questions.

Phone consultation:

  • All services contained in the written second opinion plus an up to 10-minute telephone talk with the radiologist in which the consulting expert explains the conclusions, discusses the recommended plan and answers the patient's questions.
