Objectives: To check the degree of concordance in renal ultrasound examination between two nurses and one experienced urologist with the aim of testing nurses' competence performing renal ultrasound.
Methods: The echographic aspect of both kidneys (normal or abnormal) was evaluated. Every abnormal finding resulted in the automatic classification of the kidney as 'abnormal'. The agreement between observers was tested using the Kappa concordance index.
Results: Eventually, 75 and 45 consecutive examinations performed by the urologist and nurse MM, and the urologist and nurse NJ, respectively, were evaluable. Overall, the study tested 120 patients. Prevalence of 'abnormal' kidneys was intermediate (28-36%). The overall agreement percentage exceeded 88% (88,8-92%). Kappa coefficient was always 0.7.
Conclusions: Urological ultrasound examination by qualified well-trained nurses provides records very similar to those delivered by an experienced urologist.

Background: In patients with post-thrombotic syndrome (PTS), stent recanalization of iliofemoral veins or the inferior vena cava can restore venous patency and improve functional outcomes. The risk of stent thrombosis is particularly increased during the first 6 months after intervention. The ARIVA trial tested whether daily aspirin 100 mg plus rivaroxaban 20 mg is superior to rivaroxaban 20 mg alone to prevent stent thrombosis within 6 months after stent placement for PTS.

Background: Screening for breast cancer has been effective in decreasing mortality. Mammography is not readily available in resource-limited countries like India. Annual clinical breast examination has been demonstrated to be as effective as biennial mammography in reducing mortality with much less cost.

Purpose: The aim was to establish a functional MRI protocol for analyzing human stereoscopic vision in clinical practice. The feasibility was established in a cohort of 9 healthy subjects to determine the functional cortical areas responsible for virtually relief vision.
Methods: Nine healthy right-handed subjects underwent orthoptic examination and functional MRI.
Imaging on the painful and compressed nerve: lower extremity.

Aspetar Orthopedic and Sports Medicine Hospital, Doha, Qatar.
Entrapment neuropathies of the lower extremity are often underdiagnosed due to limitations in clinical examination and electrophysiological testing. Advanced imaging techniques, particularly MR neurography and high-resolution ultrasonography (US), have significantly improved the evaluation and diagnosis of these conditions by enabling precise visualization of nerves and their surrounding anatomical structures. This review focuses on the imaging features of compressive neuropathies affecting the lumbosacral plexus and its branches, including the femoral, obturator, sciatic, common peroneal, and tibial nerves.

Background A comprehensive assessment of skeletal muscle health is crucial to understanding the association between improved clinical outcomes and obesity as defined by body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) in lung cancer, but limited studies have been conducted on this topic. Purpose To investigate the association between BMI-defined obesity and survival in patients with non-small cell lung cancer who underwent curative resection, with a specific focus on the status of skeletal muscle assessed at CT. Materials and Methods This retrospective study investigated Korean patients with non-small cell lung cancer who underwent curative resection between January 2008 and December 2019.
