Potential application of Ga-FAPI PET/CT for diagnosing cardiac sarcoidosis.

Detecting cardiac sarcoidosis; a potentially life-threatening condition is challenging and requires a multimodality imaging approach using echocardiography, PET/CT and CMR. Although 18F-FDG is the recommended PET tracer for evaluating cardiac sarcoidosis, it is limited by physiological cardiac FDG uptake and requires stringent patient preparation/ dietary modifications before imaging. We hereby present a case of cardiac sarcoidosis demonstrating myocardial FAPI uptake on cardiac PET, highlighting the potential role of 68Ga-FAPI PET in the evaluation of cardiac sarcoidosis.

2D Shear wave elastography for evaluation of renal cortex and medulla: stiffness values in healthy children.

Purpose: To evaluate renal cortical and medullary stiffness using 2D Shear-wave elastography (SWE) in healthy children.

Methods: In this IRB approved prospective study, we measured the stiffness of cortex and medulla of children (4 months-17 years) at the upper pole, mid pole, and lower pole in bilateral kidneys.

Results: The median (IQR) values of renal cortex in <1 year age group was 8.
