Graf ultrasound screening is considered an established method for early detection of developmental dysplasia of the hip (DDH). Although characterized by a high degree of standardization to allow for good reproducibility of results, examination-related factors may still affect sonographic measurements. The relative tilt angle between the hip and the probe is a potential pitfall as it significantly influences sonographic measurements and consequently classification of DDH according to Graf.

For two decades the ASCO CAP HER2 testing criteria have included 0 and 1+ scores, but this distinction was inconsequential. Now, based on the DESTINY Breast-04 Trial (DB-04) results, for patients with metastatic breast cancer it underpins eligibility for T-DXd treatment. Discerning 0 from 1+ IHC staining is challenging, as HER2 low is not a biologically distinct cancer subset, there are no reference standards or controls and second-tier tests do not apply.

Non-invasive evaluation of glymphatic function has emerged as a crucial goal in neuroimaging, and diffusion tensor imaging along the perivascular space (DTI-ALPS) has emerged as a candidate method for this purpose. Reduced ALPS index has been suggested to indicate impaired glymphatic function. However, the potential impact of crossing fibres on the ALPS index has not been assessed, which was the aim of this cross-sectional study.

This study aimed to investigate the impact of selected analysis conditions on blood flow values and color maps in canine brain perfusion computed tomography (PCT) and to propose optimal analysis conditions. Dynamic computed tomography imaging was performed on six beagle dogs. Color maps were generated using a combination of analysis algorithms (box-modulation transfer function (Box-MTF) and singular value deconvolution plus (SVD+) methods), slice thicknesses (4.

Sample size estimation is a critical aspect of nutrition research methodology, yet it remains frequently overlooked, leading to underpowered studies and potentially inaccurate conclusions. This review addresses this gap by providing comprehensive guidance on how to calculate sample size in nutrition research. Emphasizing the importance of an a priori sample size calculation, the review outlines the key considerations, including the desired levels of significance and power, effect size estimation, and standard deviation assessment.
