[Blue Lungs in Covid-19 Patients: A Step beyond the Diagnosis of Pulmonary Thromboembolism using MDCT with Iodine Mapping].

Objective: To evaluate the diagnostic capacity of pulmonary angiography with multidetector computed tomography (MDCT) and iodine mapping in the diagnosis of pulmonary thromboembolism (PTE) in patients with Covid-19 disease.

Methods: Retrospective observational study of 81 consecutive patients admitted with Covid-19 respiratory infection who underwent MDCT for clinical suspicion of PTE (sudden dyspnea, chest pain, hemoptysis, severe respiratory failure (SRF) not corrected with high O flow) and/or raised D-dimer.

Results: Of the 81 patients studied [64 (79.

Image guided SBRT for multiple liver metastases with ExacTrac Adaptive Gating.

Aim: To report the outcome and toxicity of sequential stereotactic body radiotherapy (SBRT) for multiple liver metastases in patients treated with ExacTrac Adaptive Gating.

Background: In selected patients with a limited number of liver metastases, SBRT has been evaluated as a safe and effective treatment, with minimal toxicity and high rates of local control.

Materials And Methods: From April 2008 to October 2013, 21 patients with multiple (3-14) liver metastases ( = 101) were treated sequentially with SBRT at our institution.

Follow-up of aneurysm neck diameter after endovascular repair of abdominal aortic aneurysms.

We assessed aneurysm neck diameter change after endovascular abdominal aortic aneurysm repair (EVAR) and its relationship to stent-graft diameter. Ninety-eight patients with abdominal aortic aneurysm who underwent EVAR were studied with multislice computed tomography following a standardized protocol. A preoperative study and immediate postoperative, 6-month, 1-year, and 2-year follow-up studies were performed.
