Background Data on the diagnostic accuracy of ultralow-dose (ULD) CT protocols for periodic surveillance in recipients of lung transplant are lacking. Purpose To assess the potential for radiation dose reduction using ULD photon-counting CT (PCT) to detect lung abnormalities in recipients of lung transplant during repeat CT follow-up. Materials and Methods Consecutive adult recipients of lung transplant undergoing same-day standard-of-care low-dose (LD) and ULD PCT from March 2023 to May 2023 were prospectively included.

- The study compared three-dimensional (3D) reconstructions of median and ulnar nerves using high-resolution ultrasound (HRUS) and magnetic resonance microscopy (MRM) to evaluate their effectiveness in showing nerve anatomy.
- Using three fresh-frozen specimens, researchers performed HRUS imaging and then MRM after nerve excision, leading to the estimation of nerve structure volumes and connections.
- Results showed that MRM provided more detailed images, revealing more fascicles and interfascicular connections than HRUS, highlighting HRUS's limitations in assessing peripheral nerve anatomy fully.
Tendon involvement and its association with pain and hand function in patients with osteoarthritis of the hand.

Article Synopsis
- The study aimed to assess how often tenosynovitis and tendon damage occur in patients with hand osteoarthritis (HOA) and how they affect pain and hand function using both clinical exams and ultrasound (US).
- A total of 86 HOA patients and 23 matched control subjects were evaluated, revealing that 69.8% of HOA patients had tendon involvement compared to only 8.7% of controls, with different rates of damage in flexor and extensor tendons.
- Despite finding significant tendon involvement through US, the results showed no correlation between tendon issues and hand function or reported pain levels in HOA patients.
Purpose: Pre-surgical information about tumor consistency could facilitate neurosurgical planning. This study used multi-dynamic-multi-echo (MDME)-based relaxometry for the quantitative determination of pituitary tumor consistency, with the aim of predicting lesion resectability.
Methods: Seventy-two patients with suspected pituitary adenomas, who underwent preoperative 3 T MRI between January 2020 and January 2022, were included in this prospective study.
(1) Background: The use of complementary and alternative medicine (CAM) has seen a notable increase in popularity. However, there is an absence of data regarding the prevalence of CAM use in patients with rare bone diseases (RBDs). (2) Methods: This monocentric, cross-sectional study was carried out in a reference hospital for RBDs.

Furthermore, the gliding patterns of the median nerve were characterized. The presence of vertical gliding was intended to serve as an additional bio-kinematic parameter of median nerve movement, and will be referred to as a 'level change'.
