What Can A Ct Scan Detect
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
Only at certain time: Bulky lesions in the retroperitoneum or masses growing off the bowel are frequently visualized. The same holds true for metastatic lesions to liver and lung. When we work up a patient for extensive surgical resection and want to be sure no metastatic focus is present to be addressed or might obviate the surgical procedure, a PET/CAT scan is employed where any malignant lesion lights up. ...Read more
Several things: An f18-fdg pet scan will highlight cells in your body that are consuming glucose at a different rate (usually higher) than its surrounding tissues. A neoplasm with abnormal growth consumes more glucose and thus could be revealed with this test . It is a very sensitive but not very specific test. Several other things that are not neoplasms such as infections or inflammation would also be revealed. ...Read moreSee 2 more doctor answers
Better details: The resolution, details shown, on ct is more effective than that of ultrasound. Ultrasound shows liquids e.g. Cysts and effusion better and is cheaper but in obese patients ultrasound has limited penetration. Accordingly, ultrasound, in these patients, is usually replaced by ct that views fatty tissues better and penetrates as deep as needed for better resolution. ...Read moreSee 1 more doctor answer
Anatomic/physiologic: Pet scan involves intravenous injection of radio tracer usually f18 fdg.Imaging of whole body occurs for localization of areas of increased glucose metabolism. Malignant tumors usually most active.Ct scan involves x-ray and performs anatomic imaging of parts of body usually head, chest, abdomen, pelvis, or extremities. Pet?Ct combines imaging modalities for anatomic localization of areas of uptake. ...Read moreSee 1 more doctor answer
What can detect things better inside the body a CT scan or MRI or ultrasound?, can a CT scan detect things better then ultrasound?
Sometimes. : It depends on many factors, the size of the cancer, the organ it involves, technical factors with the study, etc. There are many variables. Remember each cancer starts as a single cell, so we can never completely exclude the diagnosis even when a ct is completely normal. Pet/ct can show cancers that are virtually impossible to see on ct, even with contrast. ...Read moreSee 1 more doctor answer
What is the question: Currently pet scans are widely use for evaluation of glucose metabolism in the body. In oncology, is use to for initial metabolic characterization of tumors, metastases as well as for treatment response and surveillance. In cardiology, pet scans are use to assess heart ischemia and viability and in neurology the study is use to evaluate cognitive disorders, epilepsy and brain tumors ...Read moreSee 3 more doctor answers
See below: An MRI or magnetic resonance imaging is a study that provides anatomical description of a part of your body. A pet scan can provide further information aside from how it looks or appears. It utilizes radioactive material or tracers that see how cells in your body function. It can detect cancer cells not evident on MRI or ct, heart disease, infection and even neurological conditions like dementia. ...Read moreSee 2 more doctor answers
Can a CT scan detect pregnancy when having a CT scan for appendix? How early cam it detect a pregnancy ?
Shouldn't be used: Nearly all facilities will test for pregnancy with a blood test prior to performing a ct scan on a women of childbearing age due to potentially harmful radiation effects to a developing embryo or fetus. Whether they told you or not they probably checked at the time you were evaluated for appendicitis. It is rare to see a fetus on a ct scan because of this, but sometimes is seen in emergency scan. ...Read moreSee 1 more doctor answer
It depends: Both are very good at imaging various parts of the body. Depending on the body part and the question being asked, ct or MRI may be better. In general, MRI can "see" the soft tissues a little better (e.g., brain and spinal cord, rotator cuff) and ct is sometimes better for looking at the bones (e.g., facial fractures, sinuses). Doctors work closely with radiologists to determine the best test. ...Read more
MRA shows arteries: Mr angiography (mra) is an MRI which uses special sequences/techniques to highlight the arteries in the area scanned to look for abnormalities such as aneurysms. Like any test, it is not 100% accurate, but performed correctly and interpreted by a qualified radiologist, it is a great test to screen for arterial abnormalities. ...Read moreSee 2 more doctor answers
Yes: It can detect a brain tumor, but will be better able to detect a tumor if it performed with IV contrast. Mri with contrast can detect very small tumors that may not be seen with a ct scan. However, it is very uncommon for a 28 yr old to have a brain tumor- not impossible- just uncommon. ...Read moreSee 1 more doctor answer
