CT scan and its cancer risk

Posted on by 0 comment

Overuse of CT scan is causes to cancer. According the records now CT scan is become first choice for physicians to diagnose some normal conditions like back pain. According to the official record CT scan is growing at about 12 percent each year. Well, some radiologists are showing their concern regarding CT scan, they are requesting to the doctors to be more careful about ordering CT scans.
Ct scans causes cancer by 0.04%. Well, sometimes CT scans are very useful and saves patients from some undertaking more invasive checkups. Most of the CT scans ordered by physicians are appropriate.

What is CT Scan Exactly:-

Computerized tomography or CT scans is a medical imaging method for capturing cross sections images. CT scans can expose patient for medical ionizing radiation .
CT scans machine expose higher radiation dose than any conventional x-ray machine.
Here we’ve an example for this:-
CT scan of chest is expose 100 times more radiation dose as comparatively any routine chest x-ray

CT scan is really very dangerous?? :-

The risk of developing cancer from a CT scan is relatively 0.4%, and very small. It is recorded that more than 300 new cases of the disease cancer every year in Australia may be attributed to the radiation expose. This report is based on estimation of the government that near to 114,000 Australians suffering from cancer, and getting cancer every year.

According to the council:-

It is decided by the cancer council that CT scans should not be for those patients who are having normal back pain, fever, unexplained weight loss, and recent significant injury.

Examples for unnecessary CT scans:-

• Patients who have been successfully treated for cancer and long term follow up in the patients.
• Routinely scans for common symptoms like normal back pain.
• To avoid medico-legal issue.

Good use of CT scan:-

• To ensure that there is no metastatic disease in a patient body before any radical surgery.
• Investigation of some special symptoms, and signs in a patient body.
• Sometimes work as a substitute for an invasive procedure like laparotomy.

What should patients do in these conditions:-

If your doctor is ordering CT scan for you, you can ask to your doctor that how this CT scan will benefit for you, you can also ask for some alternative investigations.
One thing you should kept in mind that CT scan has been overly prescribed in some serious circumstances. Patients should be informed about all the risk by the physicians.
Well, CT scan is very useful in some circumstances and saves patient from some invasive test. Most of the CT scan ordered by doctors are appropriate.

How dangerous are CT scan

Computer tomography scans are useful for detect everything from cancer to kidney stones. But now some physicians and doctors rising concern about the safety and security of such procedure, because cancer risk is increasing because of the radiation exposure. Ct scan contain mega dose of radiation, 500 times more than a normal x-ray.

Study of CT scan:-

Well according to the study of some researchers and according to the survey cancer risk is associated with the CT scans.
In the first study for radiation, physicians and doctors at hospital in Florida and Washington DC, observe that randomly selected medical images of 1243 patients for the radiation effect, and calculate all radiation in each patient had sustained in past 5 years, although CT scan were the only source of radiation, other offenders are very few like x-ray machine, and mammograms, and the result of the all study presented in may at the annual meetings of society of Academic Emergency Medicine.
A review study is published in the Journal of New England is one third of all CT scan is performed in United states are unnecessary, 20 million adults and more than 1 million children per year in  USA are being observed under the CT scan unnecessary.

CT scan is increasing at very high rate to avoid this better communication is needed between patients and physicians, having the same CT scan is ridiculous.
CT scan does not give any side effect immediate; they are quick, painless, and helpful for the easy identification of the problem, send patients away with the sense of satisfaction that all is done.
Well, it is still in research that how much radiation is too much. Because CT scan is introduce in 1880 and came into vogue in the 1980’s.  And cancer from radiation hardly takes 20 years to develop. Study of CT scan and cancer from radiation still under the way. But scientists are already anticipating about the future health.
All researches found a huge population of 25,000 Japanese who survived in the atomic bomb blast and they exposed the same amount of the radiations as two CT scans.
These radiations are much harmful for children instead of adults.

Well as compared to adults children are more sensitive to these radiations because they have longer life and their cellular system works more rapidly to making their DNS system more vulnerable to various diseases. Rate of increasing cancer in a child is as high as 1 in 500. But now the newer machine made to be adjusting 50% less deliver of radiation.

But some of radiologist technician rarely make those adjustment with the machine. Changing technical factors are very easy, it just require extra time and a little thought. But many of the RTs are not trained or may be in hurry, or just lazy.

Issues with CT scans

Well, some Ct scans are totally unnecessary for the patients so better before going for the CT scan, you should talk with your doctor ; is it really necessary, can we go for ultrasound or MRI,
In some cases CT scan is necessary like severe head trauma; internal injuries diagnose an existing cancer, abdominal pain etc.

You should keep a flash drive when go for the scan so by this way you can easily keep the copy of your old scan it will help you to avoid another CT scan if the problem is same.
If you are going for your child just talk with the technician and tell them to put the machine on pediatric appropriate settings.
You cannot save yourself from the radiation but you can avoid unnecessary CT scan.

Too Much CT scans Radiation Bad for Children?

Posted on by 0 comment

Now it is very common for doctors to order immediate CT scan check up for injured children it saves time and easily identify the issues that may be not visible by doctor’s eye. But these CT scans deliver high doses of radiation to the child rather than other typical medical imaging.
This has raised concerns about the use of CT scans on children because their organs are more sensitive and cannot able to handle this kind of radiation. These radiations simply increase the chance of cancer.

 

Previous radiation effects on children :-

Rate of CT scan is increased in the emergency departments of U.S Scans rose from about 330,000 in 1995 to 1.65 million in 2008.

Ct scan machine combine special x-ray equipment with computer to produce special and clear pictures of the internal body. It is generally handled by ultrasound technician.

These cross sectioned images are being studied with the help of the computer monitor and printed and transferred to the CD.

CT scans of internal organs, soft tissue, bones, and blood vessels provide greater clarity than a simple x-ray machine.

Specialized equipment help to create more clear and interpret CT scan of the body, so by this radiologist can easily diagnose the problem like cancer, infectious disease, cardiovascular disease, appendicitis, musculoskeletal disorder, trauma, etc.

Most common CT scan for children’s are head injury, abdominal pain, and headache.
Most of the radiologists who oversee and interpret the CT scan for children are not trained in the pediatric radiology.

Ct scan machine is typically a large box with a hole, or with a short tunnel, in the center a narrow table where a patient would lie. The examination table slides into and out of this tunnel and x-ray tube and electronic x-ray detectors are located opposite each other in a round ring called as gantry.
Computer workstation that produces the images is located in a separate room, where the technician operates the scanner machine and the monitor. Sometime children are not able to hold this complete process; sedation may be needed for children. Motions will degrade the quality of the pictures.
Children are more sensitive to the radiation and the cellular system of children’s is also very sensitive, so they should only have CT scan study when it is essential.

Ultrasonography produce clear image result because small percent of body fat in children.
Well, sometimes young children are uncooperative and move during the test, and sedation is frequently required for MRI and CT scan, but in ultrasound virtually never requires sedation.
Ultrasound can evaluate the blood flow to the organs and can easily diagnose the multiple disorders.

Radiations due to CT scans

Posted on by 0 comment

Rate of CT scans are increasing, every year more CT scans are being ordered because they provide valuable information to diagnose the problem. But they come with some bad radiation.
Well, it is really nice to work with this kind of technology, and it is wonder of modern medicine that if there is some problem with patients, doctors no longer needs to cut and open to check the problem. They can take picture of exact problem, and can easily visit inside patient’s body with the help of CT scan machines.

CT scan and radiations in medical science   :-

Taking pictures from inside the body is known as medical imaging, it is started with the discovery of some x-rays in 1880’s. But the biggest advance in this field arrives in 1970’s that is CT scan machine.
Well the main difference is plain X-ray takes just one picture at a time but CT scans can be taken of cross section pictures of all the body.
This simply helps to the doctor to visualize the organs and inner part that is very complicated to identify.
Doctor can easily visualize bones, blood vessels, and can easily diagnose the health conditions like cancer,trauma,abnormalities,injuries in head and abdomen.
Both technology x-ray and CT scans are fast and pain relief.
But there is a disadvantage of using this technology is CT scans deliver radiations to our bodies while capturing the images.
Well, we all know about the high level radiations, these high levels of radiation increase the risk of developing cancer, so if you are using more and more Ct scans this will be harmful.

Radiations Exposure in CT scan:-

We all are exposed 1.5 mSv of radiation every year, and CT scans machines expose us to a dose in the range of 1 mSv to 15 mSv.
Radiation dose of a CT scan increase dramatically depending on which part of the body is being observed and the techniques used.
Well, according to some rough records a CT scan of chest is equal to the having 100 chest x-ray together. This sounds a lot for a CT scan. And the chances of cancer are increase by 0.04 percent. The estimation is based on the survey of the royal Australian college and New Zealand College of radiologist.
So if a person has 30 percent chances of developing cancer, after one CT scans it will be increase by 30.04 percent.
Age and sex matters a lot like young cells of children and breast tissue of women are more sensitive to the CT scans radiations.
All these calculation are based on the complete data from the survivors of atomic bomb blast,Rather than people who have CT scans and x-rays.Younger people may suffer from the risk of the cancer that older people because the effect of radiation takes very long time to appear in the body.
Higher level of radiation may increase the possibilities of cancer but, but at lower level dose risk is more difficult to identify.
Well, now minimizing the radiation exposure is very much important for all radiologists.
Now ultrasounds and MRI techniques much in used because these technologies do not use any kind of radiation. And the federal government is also working for this all the Medicare funding rule is changed to make MRI technology cheaper and more accessible for all the patients.
Situations where CT scans are possibly not important:-
•    Routinely investigation and normal back pain.

Well, at last all things are depend upon your doctor who suggests you for the CT scan.You should ask all the things related to your CT scan to your doctor.Keep record of all old CT scan it will save you from the unnecessary tests.You doctor must aware about your present health condition like if you are pregnant your doctor must know about it.
•    Educate yourself by accessing many good things related to CT scan machines.

Age and sex matters a lot like young cells of children are more sensitive to the CT scans radiations. Also have bad effects on women.
Most expensive thing in health care is only the doctor’s pen not MRI’s, ICU care, and open-heart surgery.

Well, patients don’t even know about the radiation they only come from the imaging test because they have read about them, had their loved ones go through them, seen them on T.V.

Discuss with your doctor:-

Well, some Ct scans are totally unnecessary for the patients so better before going for the CT scan, you should talk with your doctor ; is it really necessary, can we go for ultrasound or MRI,
