We described the role of MDCT with its new applications for determining the cause and site of bleeding, and to determine the additional benefit of MDCT angiographic technique in identifying the site of bleeding and its vascular origin.  PATIENTS AND METHODS: 50 patients suffering from hemoptysis were evaluated by MDCT with its new applications & MDCT angiographic technique. RESULTS: MDCT revealed excellent diagnostic method for hemoptysis. CONCLUSION: MDCT is considered a primary noninvasive imaging modality in the evaluation of patients with hemoptysis. It also serves as a guide for other diagnostic or therapeutic procedures.
