A member asked:
Would an mri or ct show something the size of a pinhead, about 2mm?
A doctor has provided 1 answer
Close, if there is: Enough contrast with adjacent structures. Radiologists (physicians with 5 or more years of additional training after medical school) routinely identify pulmonary nodules in the lung down to 2 millimeters, and 1 mm nodules can sometimes be identified. Certainly, 3 mm nodules are clearly seen at both ct and MRI in many organs, if different in appearance from the surrounding tissue.
