re·gion of in·ter·est

in computed tomography or other computerized imaging, an interactively selected portion of the image, the individual or average pixel values of which can be displayed numerically.

region of interest (ROI)

an area on a digital image that circumscribes a desired anatomical location. Image processing systems permit drawing of ROIs on images. The average parametric value is computed for all pixels within the ROI and returned to the operator.

region of interest

An MRI term for the region of anatomy being scanned.

(rē'jŭn in'trĕst)
In computed tomography or other computerized imaging, an interactively selected portion of the image allowing individual or average pixel values to be displayed numerically.

Patient discussion about region of interest

Q. Any idea on how to meet people who suffer from alcoolism in my region?

A. if you look for an AA meeting near your home- that should not be a problem- just "google" it. or ask your doctor to reffer you to the nearest clinic.
take care! and good for you on that big step!

Q. Is there any problem, if an arachnoid cyst ,2cmx1.5cm size, rostral to cerebellar region left untreated? symptoms: repeated headaches, twitching of muscles, tiredness

A. An arachnoid cyst that leads to symptoms usually needs treatment. Mild symptoms as you suggested are ok to left untreated however gradual onset of new symptoms may arise such as seizures, paralysis and other complications, therefore once symptoms occur one should consider treatment.

Q. experiencing sharp pain in my right kidney region... pain is acute and doesnt radiate... recently PE left lung have been taking warfrin, panadiene forte, two kinds of cholesterol/triglycerine reducing meds and champix quit smoking medication... recently tests showed the hight cholesterol and triglys' levels and also a swollen liver... pain is not in my liver area... past pain in this kidney recurrent but never as bad. always dull.. many years ago had a uti, which caused high protiene levels.. very bad at finishing anti-biotics... recently had tonsilitis.. This hurts and is tender to touch but does not bring on sharp pain when touched, sharp pain comes and goes after taking pain relief

A. Go to see a doctor - although its tempting to make the diagnosis over the net (I have several ideas about what it might be), it sounds like serious, especially if you had a PE lately - it could be a thrombus in the vein of the kidney, or maybe a stone (sounds like that according to the description of the pain). However, as I said, making the diagnosis without even seeing you isn't the wisest thing to do.

Take care,
