Doctor Q&A for Dr. Thomas Foster

No: Radiologists are the only physicians specifically trained to interpret MRI scans. Other physicians may be able to make some sense out of MRI scans, but only radiologists have the knowledge and experience to do the best job. If a radiologist has interpreted your scan, a report was sent to the doctor who ordered it, and that doctor can explain the results to you.

Solid organs: Abdominal ultrasound evaluates the gallbladder, bile ducts, liver, spleen, pancreas, kidneys, aorta (the main artery), and inferior vena cava (the main vain). Abnormal intrabdominal fluid collections are also seen. The most common abnormalities are gallstones, kidney stones, and cysts of the liver or kidneys.

Not necessarily: If the scan was done with oral and IV contrast material, it is more likely the cancer could be seen on ct; if no contrast was used for the scan, it is unlikely cancer could be seen. Some stomach cancers are flat and not bulky; the flat ones may not be demonstrable on ct. Also, very small cancers may no be seen on ct, the best way to see stomach ca is with an upper endoscopy.
