Cancer screening CT or MRI are done frequently. What are typical and frequent findings on screening CT or whole body MRI? What these common findings mean for patients who undergo cancer screening by MRI or CT? What happens when a small lesion is found on MRI or CT scan? Leading MRI and CT radiologist discusses frequent findings on screening MRI and CT scans.

Cancer screening CT or MRI – frequent findings. Magnetic resonance imaging scan for cancer detection without cause is becoming more popular. Video interview with leading expert in radiology, CT and MRI specialist. MRI breast cancer screening is an established method now. Cancer detection with whole body MRI is advertised to consumers everywhere. There might be benefit for low dose CT scan for lung cancer screening in high risk individuals. There are new guidelines on benefits and harms of CT screening for lung cancer. Diagnostic value of screening CT and MRI is low. Usually small cysts are found. But often doctors do not know if findings are cysts or cancer. So more invasive and radiation-involving tests are done repeatedly. Get medical Second Opinion to confirms CT findings and MRI findings and understand their meaning. Medical Second Opinion helps to choose the best treatment strategy for cancer on MRI or CT scan. Seek medical Second Opinion on cancer and be confident that your treatment is appropriate. MRI cancer screening. Dr. Kent Yucel, MD. CT cancer screening. Cysts. Dr. Anton Titov, MD. You mentioned that 99% of findings on a screening CT for cancer or screening MRI for cancer are incidental findings without much significance. Nevertheless probably any finding on MRI or CT creates a lot of anxiety for a patient. And such incidental findings on CT or MRI are often followed up by invasive methods. People use pelvic abdominal chest and brain MRI and CT to screen for cancer. What are common findings on screening MRI? Dr. Anton Titov, MD. Dr. Kent Yucel, MD. MRI and CT specialist, Tufts Medical Center. Incidental findings on CT or MRI are basically falling into two classes. There are small fluid collections, we call them cysts. They can happen in a variety of organs. Cysts are generally benign. But the problem is, when cysts are small, it is very difficult to tell for sure that they are cysts. So we see these cysts in regular patients, who are being evaluated for some other reason. And if such incidental lesions are of a reasonable size, we can say they are cysts. And we can ignore them. But the problem when you start screening patients by MRI or CT, you start finding these small cysts. And you cannot be sure that they are cysts or not. So they are problem. The other thing is there are some benign spots, for lack of a better term. They can happen in the lungs, from old pneumonias or infections. They can happen in the liver. They can be small benign tumors. And again, when they are small especially, we can have great difficulty telling whether they are significant or not. So when this was first started there was a famous radiologist in America. He got a screening CT scan. And they found spots in his lung. And he then ended up having lung removed. He had lung surgery for these spots. They turned out to be nothing. So we have learned over the years not to be so aggressive with CT spots and dots. And we are doing more and more follow up imaging (after screening CT or MRI first identified them). So a lot of these patients will come back every six months, or every year. They have repeat CT or MRI for three or four or even five years to show that these lesions are not growing. So that is the risk (of screening MRI). It is a the big risk of these screening modalities. It will lead to a lot of patients are going to end up having to come back for three or four even five years for additional imaging. To prove that things that are not significant are, in fact, insignificant. In return, there is very little evidence that they will benefit in terms of finding significant lesions earlier to make the MRI or CT screening worthwhile.
