Although the use of intraoral scanners is becoming more popular, dental professionals are still presented with the challenge of obtaining precise imaging of the preparation margins. Deep preparation margins, saliva contamination, or bleeding during the scanning procedures can impair the accuracy of the digital scan. Dental dam placement can significantly improve the quality and efficiency of the digital scan, while simultaneously providing a clean restorative field and serving as a barrier to the spread of infections for the protection of dental professionals. This article describes a technique of intraoral scanning by using dental dam isolation to ensure maximum accuracy of the digital scan of the dental preparations.

Virtual biopsy for non-invasive identification of follicular lymphoma histologic transformation using radiomics-based imaging biomarker from PET/CT.
BMC Med
January 2025
Department of Nuclear Medicine, West China Hospital, Sichuan University, Guoxue Alley, Address: No.37, Chengdu City, Sichuan, 610041, China.
Background: This study aimed to construct a radiomics-based imaging biomarker for the non-invasive identification of transformed follicular lymphoma (t-FL) using PET/CT images.
Methods: A total of 784 follicular lymphoma (FL), diffuse large B-cell lymphoma, and t-FL patients from 5 independent medical centers were included. The unsupervised EMFusion method was applied to fuse PET and CT images.
Investigating the significance of SPECT/CT-SUV for monitoring Lu-PSMA-targeted radionuclide therapy: a systematic review.
BMC Med Imaging

Department of Radiological Sciences, College of Health and Rehabilitation Sciences, Princess Nourah Bint Abdulrahman University, P.O. Box 84428, Riyadh, 11671, Saudi Arabia.
Background: Quantitative molecular imaging via single-photon emission computed tomography-derived standardised uptake value (SPECT/CT-SUV) is used to assess the response of metastatic castration-resistant prostate cancer (mCRPC) patients to targeted radionuclide therapy (TRT) with [Lu]Lu-PSMA. This imaging technique determines the radiopharmaceutical distribution and internal dosimetry in patients who receive TRT. However, there is limited evidence regarding the role of image quantification in monitoring changes induced by [Lu]Lu-PSMA.

Non-operative management is the standard of care for blunt spleen trauma in stable patients in the absence of other abdominal injuries. This is a case report of a male patient in his 60s who presented to the emergency room with abdominal pain 2 days after sustaining blunt abdominal trauma. The patient was haemodynamically stable, and CT scan revealed a severe spleen injury.

Objective: The study aimed to evaluate the accuracy and safety of the semi-active robotic system for implant placement in atrophic posterior maxilla.
Methods: Patients underwent robot-assisted implant placement in atrophic posterior maxilla were identified and included. Cone-beam computed tomography (CBCT) was performed before surgery.
CT scan-derived pectoralis muscle parameters are closely associated with COVID-19 outcomes: A systematic review and meta-analysis.
PLoS One
January 2025
Department of Critical Care Medicine, West China Hospital, Sichuan University, Chengdu, China.
Background: The relationships between pectoralis muscle parameters and outcomes in patients with coronavirus disease 2019 (COVID-19) remain uncertain.
Methods: We systematically searched PubMed, Embase, Web of Science and the Cochrane Library from 1 January 2019 to 1 May 2024 to identify non-overlapping studies evaluating pectoralis muscle-associated index on chest CT scan with clinical outcome in COVID-19 patients. Random-effects and fixed-effects meta-analyses were performed, and heterogeneity between studies was quantified using the I2 statistic.
