A retrospective Chinese study of 81 patients with hemoptysis found CT angiography measures bronchial arteries only marginally larger than digital subtraction angiography (ID: 6c2c253e606f46d5). The authors support using CT angiography for preprocedural planning while cautioning against borderline measurements near a 2-millimeter threshold. For interventional teams, the finding is a practical workflow refinement: if CT-based measurements closely track angiographic sizing, it can reduce the need for immediate invasive calibration steps. The study also highlights where decision accuracy can still break down around small caliber cutoffs. Although the analysis is retrospective and single-country, it directly addresses an operational decision point that affects time, radiation exposure, and procedure planning.
