my dr told me my ct was normal so do you think its nothing serious i just saw the report and its weird and i do get pressure in the right side of my head on and off and cant figure out why
Hi and welcome to the medhelp forum. The CT angiogram of the head takes pictures of blood flow in the blood vessels of head and neck, enhanced with a dye and photographed with fluoroscopy. Normally the dye flow is even through the blood vessels and any delay could be suggestive of an obstruction, possibly any atheromathous plaque or rarely tumor. Venous contamination may mean a point of weakness or give way and needs immediate attention. MRI brain presents normal myelin as hypointense to gray matter on T2 weighted images and hyperintense on T1 weighted images. Diseases which reduce the myelin content like demyelinating diseases, the white matter takes up more water which delays T1 and T2 relaxation times, hence more signal on T2weighted and less on T1 weighted images. these changes are non specific and could be a sign of ageing, chronic ischemia due to atherosclerosis or hyperlipidemia, hypertension, hypotension, cardiac illness causing reduced oxygenation etc. these need clinical evaluation and correlation. Migraines are also associated with these findings esp. since you have them. Consult your neurologist for neurological evaluation. Best wishes and cheers.
