||
CT chest
|-

|
Tb response to treatment?
||
Indicated where response is uncertain, consider contrast if nodal disease is the main query

|-
|
Ocular Tb or other extrapulmonary Tb
||
Consider chest radiograph instead. For example in ocular Tb/Tb uveitis 60% do not have pulmonary Tb and further imaging may not enhance diagnostic pathway as it will not be sensitive for extra pulmonary disease detection and will not have a high negative predictive value for extrapulmonary disease.
