Reliability and readability analysis of ChatGPT-4 and Google Bard as a patient information source for the most commonly applied radionuclide treatments in cancer patients.

Purpose: Searching for online health information is a popular approach employed by patients to enhance their knowledge for their diseases. Recently developed AI chatbots are probably the easiest way in this regard. The purpose of the study is to analyze the reliability and readability of AI chatbot responses in terms of the most commonly applied radionuclide treatments in cancer patients.

Optimization of SUV with Changing the Dose Amount in F18-FDG PET/CT of Pediatric Lymphoma Patients.

Aims: We aim to reveal an effect of residual activity leftover within the medical materials other than the empty syringe used for injection of the tracer on SUV measurements and consequently effect on possible treatment response assessment.

Background: Staging and follow-up of pediatric lymphoma patients mainly achieved by the help of PET/CT scans. It is crucial to make an optimal imaging technique for interpreting individual images and assessing treatment response.

Quantitative Tc-MDP SPECT/CT as an alternative to F-NaF PET/CT for objective assessment of osteoblastic bone metastases.

Objective: To investigate the correlation between the standardized uptake value (SUV) metrics derived from technetium-99m (Tc) methylene diphosphonate (MDP) single photon emission computed tomography/computed tomography (SPECT/CT) and fluorine-18 (F) sodium fluoride (NaF) positron emission tomography (PET)/CT.

Subjects And Methods: A total of 129 metastatic lesions from 14 patients who underwent both Tc-MDP SPECT/CT and F-NaF PET/CT within one month were included in the analyses. The lesions with markedly increased uptake were semi-automatically segmented into a volume of interest in both SPECT and PET images by taking the 42% of maximum uptake as a threshold.

The impact of 18F-fluorodeoxyglucose PET/computed tomography on clinical staging in bladder cancer.

Aim: To determine the impact of 18F-FDG PET/computed tomography (CT) on clinical staging in bladder cancer with comparison to conventional CT and MRI.

Methods: A total of 142 patients who underwent 18F-FDG PET/CT imaging with a diagnosis of bladder cancer between 1 June 2019 and 31 December 2020 were screened retrospectively. Seventy patients who underwent diagnostic CT or MRI within 2 months before or after PET/CT were included in the study.
