A and B, Lung ultrasound images obtained with convex (A) and linear (B) probes. Multiple confluent B-lines (arrows), patchy pulmonary consolidation (asterisk, B), and thickened pleural line (between arrowheads, A) are visualized. C, Chest CT image shows reticular and interlobular septal thickening and patchy, focal opacities associated with architectural distortion. This patient was classified in critical group and was assigned to severe group for statistical analysis.

In I-131 cancer therapy, decay events damage sensitive DNA within a tumor cell nucleus, causing catastrophic single and double strand breaks. Clinical use of antibody-delivered Auger emitters could open a window for the targeted destruction of extracellular COVID-19 virions, decreasing the viral load during active infection and potentially easing the disease burden for a patient. View all figures from this study.  http://jnm.snmjournals.org/content/early/2020/07/16/jnumed.120.249748.full.pdf+html

Fig. 1 The basis of high-sensitivity SPION imaging at ultra-low magnetic fields.

(A) Magnetization of 25-nm SPIONs (green), gadolinium CA (Gd-DTPA/Magnevist, blue), and water (red) as a function of magnetic field strength (B0). (B) Magnetization as a function of magnetic field strength (B0) in the ULF (<10 mT) regime for the materials shown in (A). Superparamagnetic materials, such as SPIONs, are highly magnetized even at ULF. Paramagnetic materials, such as CAs based on gadolinium, and body tissues (which typically have diamagnetic susceptibilities close to water) have absolute magnetizations that increase linearly with field strength. Curves in (A) and (B) were reproduced from data in (3253) and reflect the magnetic moment per kilogram of compound. (C) Highly magnetized SPIONs (brown) interact with nearby 1H spins in water, shortening 1H relaxation times, and causing susceptibility-based shifts in Larmor frequency.
