Background: Triple rule-out computed tomography angiography (CTA) provides imaging of the coronary arteries, pulmonary arteries, and thoracic aorta filled with contrast material (CM) to exclude or diagnose the pathologies of these three systems. Although dual rule-out adapted to exclude aortic and pulmonary pathologies. Iodinated CM may result in contrast-induced nephropathy, which lengthens hospital stay.

To evaluate dual-layer dual-energy computed tomography (dlDECT)-based characterization of thrombus composition for differentiation of acute pulmonary embolism (PE) and chronic thromboembolic pulmonary hypertension (CTEPH). This retrospective single center cohort study included 49 patients with acute PE and 33 patients with CTEPH who underwent CT pulmonary angiography on a dlDECT from 06/2016 to 06/2022. Conventional images), material specific images (virtual non-contrast [VNC], iodine density overlay [IDO], electron density [ED]), and virtual monoenergetic images (VMI) were analyzed.

Department of Pulmonary Medicine, Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Dhanvantari Nagar, Puducherry, India.
Background: The estimated incidence of pulmonary embolism (PE) is around 60-70 cases per 100,000 people annually. The overall mortality rate for massive PE is substantial, ranging from 18% to 65%. We can utilise changes in lung perfusion to stratify patients with PE acutely based on risk, highlighting its diagnostic and prognostic value.

Background: Contrast-induced nephropathy (CIN) defined as an acute kidney injury following the administration of iodinated contrast medium (CM). Hysterosalpingography (HSG) is a radiologic procedure used to investigate the shape and structure of the uterine cavity and the patency of the fallopian tubes in the evaluation of infertility. To date, there have been no reports evaluating the development of CIN after HSG procedure.
