CT scans associated with
increased risk of blood cancers
What's
in the news?
●
Ever since physicians started using
computed tomography (CT) for medical imaging, its use grew rapidly. The
benefits of CT imaging in clinically needed cases are well known.
●
However, its potential for increased
cancer risks and relatively high cumulative doses from multiple scans have
raised concerns among the medical and scientific community.
●
Sensitive sections such as children,
adolescents and young adults are vulnerable and technologists must use
appropriate protocols for them while they undergo CT scans.
CT
Scan:
●
The CT scan full form is a Computed Tomography Scan.
●
The scan usually takes cross-sectional images of the internal
organs to check the presence of any tumour or fracture within the bones.
●
The test also determines the abnormalities in the blood vessels and
is used to check cardiovascular disease.
Advantages
of CT scan:
●
CT Scan is usually suggested by doctors to
analyse any trauma to the internal organs. CT scans are known to offer highly
detailed cross-sectional images of the body. With this one can get precise
images of bones, blood vessels, or soft tissues to diagnose a different medical
condition
●
Unlike other scan types, CT scans offer a wide range of applications in the medical
field. The results help to analyse the different parts namely, the pelvis,
chest, and abdomen to detect fractures, tumours, vascular diseases, etc
●
As compared to MRI scans, CT scans are comparatively quick in results. This is
perfect for better patient care and faster diagnosis
●
CT scans are non-invasive, meaning they do not require any surgical incisions.
The process usually is very easy and one has to simply lie on a table and the
scanner will move over their body
●
In contrast to other scanners, CT scan
machines are widely available in all mid and large hospitals and medical
centres. This is great for diagnosing the problem during an emergency
situation.
●
CT Scan is a completely safe process for patients as the dose of the radiation
is slightly less than that of other scan types.
Concerns:
●
There are several risks associated with the CT scan namely, cancer, allergic
reactions, flashing, itching, etc.
