Purpose: To image lower extremity arteries by CT angiography using a very low-dose intra-arterial contrast medium in patients with high risk of developing contrast-induced nephropathy (CIN). Materials and Methods: Three cases with long-standing diabetes mellitus and signs of lower extremity atherosclerotic disease were evaluated by CT angiography using 0.1 ml/kg of the body weight of contrast medium given via 10-cm-long 4F introducer by puncturing the CFA. Images were evaluated by an interventional radiologist and a cardiovascular surgeon. Density values of the lower extremity arteries were also calculated. Findings in two cases wer . . .e compared with digital subtraction angiography images performed for percutaneous revascularization. Blood creatinine levels were followed for possible CIN. Results: Intra-arterial CT angiography images were considered diagnostic in all patients and optimal in one patient. No patient developed CIN after intra-arterial CT angiography, while one patient developed CIN after percutaneous intervention. Conclusion: Intra-arterial CT angiography of lower extremity might be performed in selected patients with high risk of developing CIN. Our limited experience suggests that as low as of 0.1 ml/kg of the body weight of contrast medium may result in adequate diagnostic imaging. © 2016, Springer Science+Business Media New York and the Cardiovascular and Interventional Radiological Society of Europe (CIRSE)

Purpose: To investigate the safety, efficacy and long-term results of bronchial artery embolization with microsphere particles (Embosphere® Microspheres, BioSphere Medical, Rockland, MA) 700–900 µm in size for massive hemoptysis. Methods: One hundred and seventy-four patients (94 female, 80 male; mean age 39.4 ± 5.7) who had bronchial artery embolization for massive hemoptysis between January 2010 and October 2015 were incorporated in the study. Patients had hemoptysis with a mean volume of 525 ± 150 mL (median 500 mL, range 300–1200 mL) over a 24-h period. Underlying pathologies included bronchial artery hypertrophy due to bronchie . . .ctasis (56.3% [98/174]), lung cancer (29.9% [52/174]), tuberculosis (10.3% [18/174]) and the rest remained idiopathic (3.4% [6/174]). Mean bronchial artery diameter before the intervention was 3.8 ± 1.5 mm (median 4 mm, range 3.1–7.5 mm). Median follow-up period was 56 months (range 10–82 months). Primary objectives were the technical and clinical success. Results: Technical success was 100%. Clinical success for preventing massive hemoptysis was 91.9% (160/174). There was no procedure-related mortality or morbidities. Minor complications such as chest pain were observed in nine patients (5.0%). Recurrent hemoptysis (8.1%) was observed within 6 months in 14 patients, ten of whom were treated with a second embolization session and the remaining four with a total of three embolization sessions. Conclusion: Bronchial artery embolization for massive hemoptysis with Embosphere particles 700–900 µm in size is a safe and effective method with high technical and clinical success rates. Long-term results are excellent. © 2017, Springer Science+Business Media, LLC and the Cardiovascular and Interventional Radiological Society of Europe (CIRSE)

We report the case of an inflammatory abdominal aortic aneurysm incidentally detected clearly with diffusion-weighted magnetic resonance imaging (DW-MRI) during the examination of a patient with myelofibrosis with myeloid metaplasia that later converted to acute myeloid leukemia. DW-MRI revealed a hyperintense halo surrounding the abdominal aorta with aneurysmatic dilatation, establishing the diagnosis. © Springer Science+Business Media, LLC 2009.
