Functional scans in cardiovascular magnetic resonance (CMR) adopting bSSFP sequences suffer from dark band artifacts due to B inhomogeneity. The best remedy to mitigate this issue is through cardiac B shimming. The development of an optimal B shim strategy for the human heart is hindered by a limited understanding of B conditions in clinical diagnostic orientations of CMR.

- The study investigates how the structure and growth potential of the proximal tibia compares to the distal femur in children during their growth spurt using diffusion tensor imaging (DTI).
- It involved 108 healthy children, analyzing DTI parameters like tract number, length, and volume, and finding that the proximal tibial tracts were more numerous in the central area while distal femoral tracts were more peripheral.
- The results indicated that tibial tract volume was significant during peak height gain, showing that the tibia's growth patterns occur earlier than those of the femur.
Hypophosphatasia is a rare heritable disorder of bone mineralization, with a spectrum of severity based on age of initial presentation. We describe the case of a 14-year-old boy with gene-confirmed inherited hypophosphatasia and growth hormone deficiency, who presented with short stature, unremarkable radiographs, and only minor physeal and metaphyseal changes on magnetic resonance (MR) imaging. Diffusion tensor imaging (DTI) before growth hormone initiation revealed abundant, non-parallel tracts in the physes and metaphyses with loss of the typical columnar organization.

Article Synopsis
- Many COVID-19 survivors from the early pandemic showed signs of cardiac injury, prompting investigations into long-term heart effects using cardiac imaging techniques like CMR and TTE.
- A study involving 40 COVID-19 survivors and 12 matched controls conducted TTE and CMR at an average of 308 days post-infection, revealing no significant differences in heart structure, function, or tissue abnormalities between the groups.
- The findings suggest that there is no lasting damage or inflammation to the heart in these survivors, despite previous reports of cardiac issues during acute COVID-19.
