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

Flat images look three-dimensional. Any explanation for this vision problem?

Flat images look three-dimensional. Any explanation for this vision problem?

Unusual symptom: This an unusual symptom. Probably this is an optical effect, but only an eye exam can rule out at problem. The 3-d effect comes from different mechanisms. 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

What to do if i get headaches when watching 3-d movies. What should I take to prevent that?

What to do if i get headaches when watching 3-d movies. What should I take to prevent that?

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

Prescription glasses, making things 3-d looking. How is this possible?

You can see!: Some of my patients have remarked to me on how prescription glasses allow them to see very well, including comments that they now see in hd or 3d. What they are observing is how great the eye can really see when given the proper correction. Wear your glasses and enjoy the good vision. ...Read more

Here are some...: The reported testicular size is on low end of normal value, but not necessarily clinically significant regarding testicular function in testosterone secretion and sperm production. So, it would be most beneficial for you to direct this very question to your urologist for more individual detail. ...Read more

Will a 3-D MRI show blockage in the proximal and distal circumflex arteries; also, the level of RCA disease? Murrell

Will a 3-D MRI show blockage in the proximal and distal circumflex arteries; also, the level of RCA disease? Murrell

MRI or MRA? CTA angi: The question's somewhat vague. Are you asking about 3-D vs. 2-D MRI? Or MRI vs. MRA (Magnetic resonance angiogram)? MRI can show changes in tissue that are effects of arterial blockage. The actual arteries themselves are seen by MRA. The size of artery blocked determines whether or not it can be seen. More proximal = larger artery = easier to see blockage. The heart moves, & MRI pics often blurry. ...Read more

Got a large abrasion 3 d ago and have kept covered with neosporin. It's red around the wound, but not warm and no smell. What else to do? Redness ok?

Got a large abrasion 3 d ago and have kept covered with neosporin. It's red around the wound, but not warm and no smell. What else to do? Redness ok?

May need an exam: Wounds have redness around them when they are trying to heal, because a healing wound gets extra blood flow to it, and that extra blood flow gives the area a reddish color. Infections also cause extra blood flow and redness, so it can be hard to tell when an infection is starting up just by looking at the redness. An exam is needed if worried, if redness is spreading, if pain is growing, etc... ...Read more

Yolk sac but no fetal pole/embryo. Supposed to be 6 w 3 d b/c I had an IUI but I'm measuring 5 w 1 d. Whythe discrepancy in dates? Where is baby!?

Yolk sac but no fetal pole/embryo. Supposed to be 6 w 3 d b/c I had an IUI but I'm measuring 5 w 1 d.  Whythe discrepancy in dates? Where is baby!?

Too early to tell: Presumably you had the IUI when you were ovulating. If that was the case, I would expect the usn to show a 6W3day embryo, so the size difference is of some concern. But sometimes people ovulate later and so it makes sense to recheck the usn in one week to see if there is growth/ heartbeat. The fact that there is a yolk sac is great news. ...Read more

Find out what: It appears that finding out what the nodule is would be the next step. If it is thought to be cancer, surgically removing it may be an option, otherwise a biopsy would be the next step (usually). Talk to your pulmonologist. ...Read more
