In radiology, which examination using barium are no longer preformed and why? Which still are?

Barium studies of the GI tract (both upper and lower) are still done routinely.  The only times you don't use it are if the patient is allergic or if you suspect a perforation or complete obstruction (which could lead to a perf).\n\nIf you're looking for diverticuli, stenoses, dilations, or any other anatomic defect of the GI tract, there really is nothing better than a barium contrast X-ray/CT.

Known as X-rays, Roentgen rays are routinely used to assess dental health and used as needed for analysis of bone fractures, and lung ailments and diseases such as cancer. Since there is a slight risk of cancer due to excessive exposure to X-rays, they are not used for routine checkups as they once were (e.g., fluoroscopes). See the ref.

okay, I'm thinking "why do you people assume we might have metal in our EYES?!"\nbut ....\n\nBefore the test\nYou will need to remove all metal objects (such as hearing aids, dentures, jewelry, watches, and hairpins) from your body because these objects may be attracted to the powerful magnet used for the test. If you have had an accident or you work around metal and there is a possibility that you have metal fragments in your head, eyes, skin, or spine. X-rays may be taken before the MRI to confirm the presence of metal and to determine whether you can have the test.\n\nalso, it says to watch out for metallic tattoos.

There are several different methods and applications. The most common is using them as contrast agents: the solution containing radioactive isotope (say Iodine) injected into specific side (depends on the area of interest - might be specific organ or vessel) and after that using special radiation detecting equipment they monitor the movement of this agent through specific tissues or blood. Using this technique many health problems can be diagnosed. The radioactive istotpes used here are usually short living and do not cause hurm to the body.

specifically in those days it was not.  you can risk getting your brain in an unpredictable condition.  But today there is now a special kind of x ray just for the brain.

Do you mean "radiological controlls technitions" or "radioghraphy technitions"?  I'd need too know more before I commited to answering this question.

The previous answerers did a good job explaining the terminology so I'm going to skip to the significance, which in this case isn't much.  \n\nAccentuated hilar and basal bronchovascular markings is quite a common finding in chest x-rays that could mean anything from normal to very serious disease (if associated with other findings).  It is used as either to confirm a diagnosis by other methods, or as a starting point to investigate further.  \n\nThis finding alone could simply mean that the subject of the x-ray is a smoker, has an acute (e.g. pneumonia) or chronic (e.g. asthma) pulmonary disease, has some degree of valvular heart disease, etc.  Do not read into this more than it merits, but do consult with the doctor that ordered the x-ray to understand what he/she concluded from your work up.

MRI:\n\n\nAn MRI (or magnetic resonance imaging or nuclear magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. These images can detect the difference between normal and diseased tissue.\n\nMRI makes better images of organs and soft tissue than other scanning techniques, such as CT or x-ray. Breast MRI is excellent at imaging breasts with implants. MRI is also useful for staging breast cancer, determining the most appropriate treatment, and for patient follow-up after breast cancer treatment. MRI is especially useful for imaging the brain, spine, the soft tissue of joints, and the inside of bones.\n\nXray:Chest x-ray (also known as Chest Radiography) is done for the evaluation of the lungs, heart and chest wall. IBC patients will have chest x-rays to determine their Staging and their ability to receive certain chemotherapy agents like Adriamycin which can be damaging to the heart.\nRadiography involves exposing a part of the body to a small dose of radiation to produce an image of the internal organs. When x-rays penetrate the body, they are absorbed in varying amounts by different parts of the anatomy. The ribs and spine, for example, absorb much of the radiation and appear white or light gray on the image. Lung tissue absorbs little radiation and appears dark on the image. Depending upon the type of image-recording medium, chest x-rays can be maintained as hard copy film for filing or as filmless digital images that are archived electronically.

I would say that Bobbie gave a pretty accurate description.  Our facility requires a blood test before your CT scan if you are over age 60 or a diabetic.  If you are a diabetic and on glycophage, you must stop this medication 2 days prior to the exam and also have another blood test post exam before you can start taking your meds again.  This is to ensure your kidneys are functioning properly.  If you have any prior examinations of your abdomen (IE: ultrasound or KUBs), make sure they are available to the radiologist who will be reading your CT scan.

For more info, google NMR.... the medical communicty did not want the term nuclear used out of patient concern, so they adopted the term magnetic resonance imaging. Technically it shoud be nuclear magnetic resonance imaging... even though ionizing radiation is not present. \n\nThere are multiple magnets. The large magnet provides a static field, and smaller controlled magnets allow the specific magnetic field for a given pixel to be changed, such that cross sectional mapping can occur. In addition, the smaller magnets may also be used to stablize the field created by the larger one. \n\nThe wikipedia entry is a good one, if you want more indepth knowledge a good reference is available at\nhttp://www.cis.rit.edu/htbooks/nmr/chap-3/chap-3.htm

That is an old name for a series of chemistry tests and that name is not even used anymore unless you have an older doctor.  Has glucose, sodium, potassium, also cholesterol and more.

In Singapore, for diagnostic imaging we use Iodine 123.\n\nI think actually Iodine 131 is used for radioablation too. We don't use the 127 isotope where I come from so can't help you with that.

This should have been arranged before your appointment. It is up to your doctor to order and schedule both tests. To show up and expect that the MRI technologist will just do both is very inconsiderate of the patients that will follow your appointment as a MRI usually takes  about 45 minutes and this will cause all the patients after you to be at least an hour late with their appointments.  If there is an open spot after your knee scheduled time, the tech can call your doctor and ask if it can be done, but this should have been brought up by you at your appointment with the ordering doctor. Many times, a reputable doctor will not order a test as expensive as an MRI without examining the patient.\n\nOR, you can call the doctor before your appointment and have BOTH tests scheduled at once. You may have to switch days to do this, but it seems to be the best option.\n\nAs for saving money, these are TWO SEPARATE exams, no discount will be given for the test, or radiologist reading.

I have been involved in medical imaging for over 15 years.  I have done medical sonography for 12 years. In OB ultrasounds, we measure the amniotic fluid....For early OB and pelvic ultrasounds, you must drink water, so that we may be what lays low in the pelvis.  There is a hysterosonogram, but, from what I know, they are not done routinely, and the procedure is relatively new.  I have never worked at a facility that does these exams.  BUT, you can read about them at these sites:  https://www.healthatoz.com/healthatoz/Atoz/ency/hysterosonography.jsp\nhttp://www.radiologyinfo.org/content/hysterosono.htm
