Computed Tomography (CT), also known as Computed Axial Tomography (CAT), is a non-invasive radiological method used for medical imaging and diagnosis, utilising X- ray radiation. With the use of a special X- ray-generating machine, widely known as a CT scanner, and advanced computer technology for processing results, detailed two-dimensional cross-sectional images of the human body are produced. These images can be stored digitally (on CD) and printed on film.
At "YGEIA FLORINAS - TOMODIAGNOSI EE," a department equipped with a modern multidetector CT scanner is operational. The LightSpeed VCT, manufactured by the American company GE Healthcare, produces high-quality images with high resolution (clarity and contrast). Belonging to the latest generation of CT scanners, it is significantly faster compared to conventional ones, allowing examinations with lower radiation exposure and enabling three-dimensional (3D) reconstructions of sections thinner than a millimetre.
All conventional and some specialised CT examinations are performed, including:
- - Classical CT scans (of the brain, skull base,
temporal bone, neck, thorax, upper and
lower abdomen, retroperitoneal area, spine,
bones, and soft tissues).
- CT angiography (of the brain, neck, thoracic and abdominal cavities, upper and lower extremities).
CT can be performed on all interested individuals following appropriate indications.
For radiation protection reasons (CT scans rely on X-ray radiation), CT is contraindicated during pregnancy. Additionally, it is avoided in children, adolescents, and young individuals without a significant medical indication.
! Depending on the indications and/or findings, intravenous iodinated contrast medium may be administered:
* In cases of an patient with a history of
allergic or anaphylactic reactions to
previous administration of iodinated
contrast agents (such as in CT or
intravenous pyelography), or with a history
of hypersensitivity reactions in general, it is
essential to disclose this information so as
to provide instructions for anti-allergic
preparation—administration of
antihistamines and corticosteroids in
combination with gastric protection if
deemed necessary.
* In cases of a patient with pre-existing renal
insufficiency or with diabetes mellitus with
confirmed diabetic nephropathy, there is a
risk of acute kidney injury (increase in
creatinine levels >25% or >2mg/dl
compared to pre-administration levels): recent (within the last two months) blood
urea/creatinine examination is necessary.
* In cases of a patient with hyperthyroidism
or bronchial asthma, there is an increased
risk of precipitating a thyrotoxic crisis.
* In cases of a patient with Myasthenia
Gravis, there is an increased risk of
exacerbating symptoms.
* In cases of a patient with
pheochromocytoma, there is an increased
risk of precipitating a hypertensive crisis.
