CT scan

Understand the ct scan procedure: when it is recommended, how it is done, safety, and how results are reported.

Liver cancer on CT scan: What does hepatocellular carcinoma look like and can it be diagnosed from the image?

Liver cancer on a CT scan is assessed not by a single “dark spot,” but primarily by how the tumor behaves after the introduction of contrast during different phases of the examination.

CT scan for breast cancer: what it shows, when it is prescribed, and whether contrast is needed

CT scanning for breast cancer is used primarily not to confirm the presence of a tumor within the breast itself, but for staging the disease—looking for the spread of cancer beyond the breast and regional lymph nodes.

PET for melanoma: when is PET/CT performed, what does the test show, and when is it not necessary?

Positron emission tomography combined with computed tomography (PET/CT) is used in melanoma primarily to search for distant metastases, clarify the stage, detect recurrence, and assess the spread of the disease.

CT scan for melanoma: when is a CT scan needed, what does it show, and how is it different from PET-CT and MRI?

Computed tomography for melanoma is not needed to confirm a suspicious mole, but mainly to search for regional and distant metastases and assess the spread of an already confirmed tumor.

Thyroid CT scan: when it's needed, what it shows, and how it differs from ultrasound

Computed tomography of the thyroid gland is a layered X-ray imaging method that clearly shows not only the gland itself, but also the trachea, esophagus, blood vessels, lymph nodes, mediastinum, and deep structures of the neck.

Computed tomography of the lungs: what the test shows, when it is prescribed, and how safe is it?

A computed tomography (CT) scan of the lungs is a cross-sectional imaging technique that uses an X-ray tube and detectors to rotate around the body, and a computer to assemble many thin slices into a detailed image of the lungs, pleura, mediastinum, great vessels, chest bones, and parts of the upper abdomen.

Computed tomography of the mammary glands: indications, possibilities, limitations and place in modern diagnostics

In real-life practice, the term "breast computed tomography" often covers two different situations. The first is a routine chest computed tomography scan, in which changes in the breast are detected incidentally.

Positron emission tomography: how it works, where it is used, and what it shows

Positron emission tomography is a nuclear medicine technique that evaluates not only the structure but also the function of tissues.

Optical coherence tomography of the eye: what the test shows, when it is prescribed, and how to correctly interpret the results

Optical coherence tomography is a noninvasive imaging technique that uses light to produce cross-sectional images of eye tissue.

Computed tomography of the heart: what it shows and when it is needed

Cardiac computed tomography (CT) is a group of X-ray examinations in which a scanner obtains thin, layered images of the heart and major vessels, and a computer assembles them into two-dimensional and three-dimensional reconstructions.
