It is observed that the locations of the most functional lymphatic vessels in the lymphedematous limbs can differ significantly from those in healthy limbs. The aim of this study was to elucidate the lymphatic map of lymphedematous limbs. We retrospectively analyzed 59 patients (118 limbs) with lower limb lymphedema.

After clinical evaluation, especially clinical prediction rules, appropriately ordered venous duplex has become the standard test for evaluating and excluding deep vein thrombosis (DVT). Ultrasound is useful for lower- and upper-extremity veins. Protocols include grayscale, color Doppler, and spectral Doppler.

Article Synopsis
- Phosphorus Magnetic Resonance Spectroscopy (P MRS) is a noninvasive technique used to assess energy metabolism, but high magnetic fields often create sensitivity and spatial issues; the novel fast double-angle method (fDAM) is proposed to address these challenges.
- The fDAM method utilizes advanced 3D acquisitions and frequency-selective pulses to efficiently map phosphocreatine signals at 7T, showing promising results in both phantom studies and human brain/muscle applications.
- The study findings demonstrate that fDAM provides a strong correlation with traditional methods while significantly reducing mapping time and improving coverage, suggesting its potential for quick P MRSI applications in future research.
Seeing through the smoke: The effects of wildfire fine particulate matter (PM) exposure on standing and lying behavior in Holstein heifer calves.

Department of Animal, Veterinary and Food Sciences, University of Idaho, Moscow, ID 83844.
Wildfires are burning more acres annually, contributing to air pollution across the United States. Air pollutants, such as particulate matter (PM), have health implications for humans and animals, and are known to alter behavior in several species, but effects of wildfire PM on dairy calf behavior are unknown. The present study aimed to understand how dairy calf standing and lying behavior is affected by wildfire PM.

Purpose: To optimize Relaxation along a Fictitious Field (RAFF) pulses for rotating frame relaxometry with improved robustness in the presence of and field inhomogeneities.
Methods: The resilience of RAFF pulses against and inhomogeneities was studied using Bloch simulations. A parameterized extension of the RAFF formulation was introduced and used to derive a generalized inhomogeneity-resilient RAFF (girRAFF) pulse.
