Comparison of Whole-Body Dosimetry Measurements in I Therapy Using Ceiling-Mounted Geiger-Müller Detectors and γ-Camera Scans: An Agreement Analysis.

In I therapies internal dosimetry is crucial for determining the mean absorbed dose to organs at risk, particularly the bone marrow, which has a dose constraint of 2 Gy. Traditionally, multicompartmental models have been used for bone marrow dosimetry, necessitating whole-body absorbed-dose assessments. However, noninvasive techniques, such as γ-camera scans or ceiling-mounted Geiger-Müller (GM) counters, can estimate the aforementioned.

Regulation of nuclear medicine services: Perception of the problems and challenges in Colombia for the approach to cancer.

Introduction: Colombia has modified the nuclear medicine norms that impact the administration of radioactive iodine therapy in the treatment of thyroid cancer. Objective: To identify the areas of agreement regarding the issue, as well as the current and emergent requirements associated with the normative for the operation of nuclear medicine services that have an impact on the care of patients with thyroid cancer in Colombia. Materials and methods: We conducted a two-round Delphi study for each expert, clinical, and regulatory group.

Impulse oscillometry reference values and bronchodilator response in three- to five-year old children living at high altitude.

Introduction: Impulse oscillometry (IOS) is used to measure airway impedance. It is an effective tool for diagnosing and treating respiratory diseases, and it has the advantage that it does not require forced respiratory maneuvers. IOS reference values are required for each population group.

Reporting of methodologic information on trial registries for quality assessment: a study of trial records retrieved from the WHO search portal.

Background: Although randomized clinical trials (RCTs) are considered the gold standard of evidence, their reporting is often suboptimal. Trial registries have the potential to contribute important methodologic information for critical appraisal of study results.

Methods And Findings: The objective of the study was to evaluate the reporting of key methodologic study characteristics in trial registries.
