Imaging Forward: How medical imaging is transforming medicine

Earlier this month, the Medical Imaging and Technology Alliance (MITA) launched Imaging Forward, a campaign to draw awareness to medical imaging's contributions to medicine. In this opinion article, MITA Executive Director Gail Rodriguez, PhD, describes how technology that was once unimaginable is now the standard of care.

Cuff occlusion paradigm shows the following: (a) Cross-sectional images of the femoral artery that were used to draw regions of interest before (rest) and after cuff occlusion (at three different time points) to determine flow mediated dilation; (b) Femoral vein oxygen saturation (SvO2) plotted vs time after cuff release. SvO2 is derived from the difference between venous and arterial signal phase. (Tw = washout time); and (c) Average blood flow velocity-time curve in the femoral artery. (HI = hyperemic index; Vp = peak velocity; Tp = time to peak velocity; TFF = time of forward flow)

Thyroid medication linked to bone loss

Levothyroxine – a common medication taken for hypothyroidism – may be associated over time with bone loss.

Does AI contribute to burnout for radiologists?

Frequent AI use is associated with an increased risk of radiologist burnout, particularly among those with high workloads and low AI acceptance.
