Another article was found that compares sinus radiographs to sinus
CT exams,2 but data were not presented in such a way
that a 2x2 table could be constructed in order to calculate sensitivity,
specificity and likelihood ratios. The article was written with
an ENT evaluation and possible surgery in mind; thus, anatomic details
were emphasized. The conclusions still favored CT exam over
radiographs for diagnostic accuracy and anatomic detail and the
article contains important contributions regarding why radiographs
may be more difficult than CT scans to interpret accurately.
