Studies of the intra-arterial bolus curve after intravenous contrast injection with dynamic computed tomography show that a higher bolus maximum can be obtained with a central injection than with a peripheral injection, other injection parameters remaining unchanged. In a singular venous injection ionic and nonionic contrast media show no different effects on the bolus curve. Due to the unfavorable effects of ionic contrast media with high osmolality, for the purposes of intravenous digital substraction angiography nonionic contrast media must be recommended. The subsequent injection of sodium chloride results in a higher bolus maximum.

Odor emissions, primarily from anthropogenic activities like waste treatment and industrial processes, pose significant challenges in urban areas, particularly near water resource recovery facilities. While these emissions are generally not toxic, they can adversely affect community wellbeing and investment, prompting stricter regulations in some regions. For example, New York State's hydrogen sulfide guidelines are more stringent than federal standards.

Cardiac MR imaging and pulmonary MR angiography (MRA) are important clinical tools for the assessment of pulmonary vascular diseases. There are evolving noncontrast and contrast-enhanced techniques to evaluate pulmonary vasculature. Pulmonary MRA is a feasible imaging alternative to CTA in pulmonary embolism detection.

Background: Ochratoxin A (OTA) is toxic secondary metabolites produced by fungi and can pose a serious threat to food safety and human health. Due to the high stability and toxicity, OTA contamination in agricultural products is of great concern. Therefore, the development of a highly sensitive and reliable OTA detection method is crucial to ensure food safety.

Sentinel lymph node (SLN) detection has been widely investigated in recent years as a part of the surgical staging of women with endometrial cancer (EC), gradually overtaking lymphadenectomy (LND) in this respect. In this study, thirty EC patients, assumed as stage I, were investigated using superparamagnetic iron oxide (SPIO) as a tracer for SLN detection followed by LND. The endpoints of this research were the proportion of successful SLN detection, the average number of SLNs per patient, the percentage of bilaterally detected SLNs, and the proportion of metastatic SLNs.

Purpose: This study investigates the risk of contrast-associated acute kidney injury (CA-AKI) in trauma patients, focusing on the impact of cumulative contrast medium doses.
Methods: A retrospective review was conducted at a level 1 trauma center (2019-2021). The study included patients who underwent intravascular contrast-enhanced examinations for torso trauma within 7 days post-injury.
