AdvantagesOutpatient procedureCheapDiagnostic procedure can be combined with therapeutic intervention in one sessionSmall lesions and difficult locations can be reachedWidely availableReal-time imageNo radiation exposure
DisadvantagesBlind procedureLow diagnostic yield#In-patient procedureRadiation exposurePrior contrast computed tomography to localise area of pleural diseasePrior contrast computed tomography to localise area of pleural disease
  • #: diagnostic yield is higher in areas with endemic tuberculosis.
