are all these done with contrast dye? i have something severe wrong with my brain and docs wont use the dye here in australia cos theyre stupid and think it makes no difference.. im sure theyre missing my diagnosis due to not using contrast
There is some value in using IV contrast in these cases, as it gives more information and can help differentiate or identify hard to diagnose lesions. However, the vast majority of the information is in the noncontrast scan. With a few exceptions, such as metastatic disease, a normal noncontrast scan would mean the study is normal probably > 90% of the time

@@LearnNeuroradiology thanks for the reply, could a noncontrast scan miss lesions? brain tumors or abscess or infections? or are they always visible
