Ct Scan Vs X Ray Pneumonia
Yes if greatly enlar: An enlarged heart can be seen on X-ray or CT scan especially if it is greatly enlarged. However, the cause for the enlargement is usually not apparent by those means. An echocardiogram (ultrasound) usually does a better job. sometimes more specialized tests are needed. However, if this is the 1st time that an enlarged heart was detected, it is best to get it confirmed & identify the cause. GL & TY ...Read more
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
What's difference between High HD Contrast CT scan vs Normal Chest CT with contrast evaluating interstitial lung markings?
Different chest CTs: High resolution chest CT usually with out intravenous contrast is used to define interstitial lung disease pattern, whether diffuse or localized process. CT of chest examination with contrast intravenously usually looking for tumors or metastases and acute infection in the lungs. ...Read more
Not the best test: A high resolution CT chest would be the best study to evaluate fibrotic lung disease. ...Read more

Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read moreSee 1 more doctor answer

Dx of lung nodules. Ct scans of chest two years. Had chestxr CT scan of chest 2012 2013 CT scan of chest pulm wants another im afraid it causes cancer?
Radiation from CT: This issue should be discussed with your pulmonary doctor and radiologist. There is some risk associated with the radiation from multiple ct scans. However, that risk is likely small compared to the risk of a nodule identified in the lung, and may not outway the risks of ct, in the long run. There should be a plan with a reasoned approach that minimizes the risk of ct that you can agree with. ...Read moreSee 1 more doctor answer
Either: I usually do them without so I don't expose the patient to the contrast, which can injure kidneys. However, if the tumor is close to the mediastinum, I usually do order it with contrast because it's often difficult to tell the various structures apart without it. It also helps to identify lymph nodes. ...Read more

If having Low-dose spiral CT scan chest, or low dose helical CT scan chest, is contrast media injection normally required? Checking lung cancer.
Yes: Some Doctors who interpret MRI exclusively in their practice will promote the idea that MRI is the best imaging technique for every condition. To a lesser extent, some Doctors will say CT. Some doctors swear by Ultrasound imaging. There are strength and weaknesses of each modality, with considerable overlap in information produced. And each modality has some advantage over others. ...Read moreSee 1 more doctor answer
Most of the time: Pneumonia is a clinical diagnosis. Xrays are usually 48 hrs behind the clinical manifestation of the disease. Diagnosis of atypical pneumonia, therefore is by clinic and could be confirmed by regular chest x ray and not ct scan. However ct scan is more detailed and more in line with clinical symptoms. Shahzeidi, md. ...Read more
It depends: Chest ct is more commonly used to evaluate the lungs, blood vessels, bones, and soft tissues. Chest mri, which takes longer to perform, is typically reserved for evaluation of diseases of the blood vessels (aorta, etc.), the heart, or masses that need to be further characterized. Chest ct is better at evaluating the lungs. ...Read moreSee 1 more doctor answer

My chest xray and CT scan show groundglass opitcity and perihilar infiltrates. I an 91. What is this. I am told it is not pneumonia. Thank You?
Abnormal CT findings: Abnormal CT/x-ray findings frequently are meaningless in absence of a patient's history,& so it is not possible to answer the question directly; there may be many possible causes of such findings.One non-pneumonia cause of CT findings of groundglass opacities & perihilar infiltrates can happen to asthmatics; it is allergic bronchopulmonary aspergillosis (an allergic response to an airborne fungus) ...Read more

Here are some ...: For an average 34-y-o female, you seemed getting a lot of radiation more than the necessity which most likely could be taken care of by good Hx + physical exam + effective counseling + collaborative F/U. Nonetheless, work closely with Doc. Besides, today's medical care has been under high pressure of political correctness, consumerism, & commercialism. Keeping these in mind will help the future. ...Read more

Unclear: There are multiple variables in determining the risk to fetus. The risk depends on the age of the fetus. The fetus is most suspective to damage in the first trimester. X-rays and ct exams taken far away from the wombs such as the head or extremities actually provide little to no radiation to the fetus. It is common procedure to cover the womb with lead if there is any chance of pregnancy. ...Read moreSee 1 more doctor answer
The short story...: Xrays are images obtained by passing a beam through a detector to simply generate and image of which xrays did or didn't hit the detector. Ct uses the same technology but reconstructs multiple imaging points using a computational algorthim to make a much more detailed picture in the form of "slices" mri uses magnetic fields and radio waves to generate and image using computers to create images. ...Read more
See below: All x-ray exposure increases your chances of developing cancer.For any test involving radiation exposure, the question is one of risk vs benefit. If there's a compelling reason/question that's prompting the scan then it's likely worth proceeding but no one should be getting scans without a good reason. If you are unclear on your doctor's thinking, ask. Then you can decide if you want the scan done. ...Read more
History and exam: Everyone generally has at least one floating ribs some have a couple on each side though usually the lower ribs. They can get irritated on your hip or on the ledge of a couch when you're leaning or a variety of other things. They are slow to heal. Sometimes you can feel them slip underneath another rib. That is uncomfortable. There's a lot of carlatun these ribs which is slow to heal. Even chest x-rays are not very helpful. Sometimes diagnostic nerve block can define things. ...Read more
Missed Diagnosis: Yes, it is possible that a diagnosis was missed on your x-ray, ct or mri. Radiologists are just like all other humans and can, unfortunately, occasionally make mistakes. If there is concern, consider asking your doctor to discuss the examination personally with the radiologist who interpreted the exam and then to discuss those results with you. ...Read more
Inform physician: Radiologists trained in imaging from residencies and fellowships usually read imaging studies. They are usually peer reviewed to avoid making errors. However they are human and can make errors.Error rate is usually universally about 3-4%. In order to improve performance of medicine providers need to be informed. In imaging as in medicine there are gray areas and everything is not black and white. ...Read more
Not usually: Depends on nuclear study. A lot of CT exams such as chest and abdomen have more radiation dose than most nuclear medicine studies. A bone scan is more dose than the CT of brain. In any event if study is necessary for diagnosis to help patient the dose becomes insignificant. ...Read moreSee 2 more doctor answers

Both use x-rays: A chest ct is a very detailed look at the lung, blood vessels, heart and bony thorax. It takes very thin (3-5mm) slices which allows for detailed analysis of lung structure. The chest x-ray takes a 3-d structure and collapses it to 2-d. This still provides very detailed information of the chest, but can lead to overlap -- sometimes requiring additional views or a ct scan to clear things up. ...Read moreSee 1 more doctor answer
