Quality assessment in bone densitometry: a case of incorrect hip analysis.

Dual-energy X-ray absorptiometry (DXA) is a sophisticated imaging technique utilized in the field of medical diagnostics to measure bone mineral density. The significance of DXA lies in its ability to accurately assess bone health, which is crucial in the evaluation of osteoporosis, a condition characterized by weakened bones and heightened susceptibility to fractures. Despite its widespread adoption and clinical utility, DXA is not without limitations.

Effect of hormonal therapy on F-fluciclovine PET/CT in the detection of prostate cancer recurrence, localization of metastatic disease, and correlation with prostate-specific antigen.

Introduction: F-Fluciclovine, is a positron emission tomography (PET) radiotracer approved for the localization of sites of prostate cancer recurrence in men with a rising prostate-specific antigen (PSA) after definitive treatment. To explore the impact of androgen deprivation therapy (ADT) on the performance of F-fluciclovine, we conducted a retrospective analysis to compare the F-fluciclovine PET/CT positivity rate in patients receiving ADT at the time of the scan with the rate achieved in patients not receiving ADT.

Methods: A retrospective review of data from patients who underwent F-fluciclovine PET/CT for biochemical recurrence of prostate cancer between December 2016 to March 2020 was performed.

A Multimodal and Pathological Analysis of a Renal Cell Carcinoma Metastasis to the Thyroid Gland 11 Years Post Nephrectomy.

Thyroid lesions have a comprehensive differential diagnosis which include benign and malignant entities, such as metastases. However, metastases only account for a small percentage of thyroid lesions with renal cell carcinoma as the most common. Metastases to the thyroid pose a diagnostic dilemma as symptoms may not manifest for up to decades after removal of the renal cell carcinoma.

Proof of Concept: Design and Initial Evaluation of a Device to Measure Gastrointestinal Transit Time.

Chronic constipation and gastrointestinal motility disorders constitute a large part of a gastroenterology practice and have a significant impact on a patient's quality of life and lifestyle. In most cases, medications are prescribed to alleviate symptoms without there being an objective measurement of response. Commonly used investigations of gastrointestinal transit times are currently limited to radiopaque markers or electronic capsules.
