I : I suggest you make an appointment with the doctor who ordered the pet scan to review the images and adults with him or her. Ctac stands for "attenuation correction ct". This is ct, or computed tomography part of the combined pet/ct scan. It is what show the anatomy meaning all the organs and structures in the body. The 3.75 just means how thick the cat scan slices are. Unless a special kind of pet/ct dcan was done specifically to evaluate for a brain tumor, it is actually quite rare for brain tumors to show up on regular pet scans and they are usually not easily seen on the ct component of the scan alone, especially if no IV contrast dye aw given in addition to the pet scan sugar tracer. ...Read more

Shadowing and parallax, for example, give a 3-d effect without depending on the 2 eyes being separated in space giving stereopsis (true 3-d vision). So, if for some reason there was a ghost image from one eye, a 3-d effect might result, possibly. ...Read more

See an Eye Doctor: Spathakh, given that the headaches appear to be associated with visual strain (even the best 3-d movies produce some strain) i would discuss this with you eye doctor to ensure that you do not need (?New) eyeglasses. You could consider pre-treating with ibuprofen, but i wouldn't avoid the possibility of new glasses as a primary solution to the problem. ...Read more
