Purpose: To quantitatively and qualitatively compare the magnitude of metal total hip arthroplasty-induced imaging artifacts in vivo between 1.5T and 0.55T MRI.

However, corneal electrode application is not tolerated by some individuals. The advent of handheld ERG devices has facilitated the use of skin electrodes for ERG measurements.

Article Synopsis
- Previous electroretinogram studies show that people with major depressive disorder (MDD) have reduced retinal contrast gain, affecting their visual perception.
- The study compares contrast suppression in 21 MDD patients and 23 healthy controls (HC) using various stimuli and finds that MDD patients demonstrate less contrast suppression, especially with high stimulus contrast.
- These findings suggest that altered dopamine function and changes in retinal processing may contribute to the visual perception issues observed in individuals with MDD.
Article Synopsis
- Pulmonary transit time (PTT) measures how long it takes blood to move from the right to the left ventricle and can indicate heart failure-related issues like diastolic dysfunction (DD) and mitral valve regurgitation (MVR).
- In a study of 83 patients using stress perfusion cardiovascular magnetic resonance (CMR) scans, higher PTT and normalized PTT (nPTT) were linked to more severe cases of DD and MVR.
- PTT values under 8 seconds can effectively rule out DD and MVR with a 70% probability, highlighting PTT as a useful and accessible measure for evaluating patients' heart conditions.
