To create this list, we started with the words that give our users the most trouble and then ranked them by how frequently they appear in our corpus of billions of words from edited sources. If you only have time to study one list of words, this is the list.
CSF cytology and HIV serology were both negative. EMG, however, confirmed the clinical findings of polyradiculopathy. T1W and T2W MRI of the lumbar spine demonstrated diffuse thickening of the nerve roots of the cauda equina, which enhanced following intravenous gadolinium administration (Figs. 1 and 2). No parenchymal involvement was seen.

A nerve root is the part of each spinal nerve that exits your spinal cord and goes through an opening in your spine.
