Background: The diagnosis of chronic rhinosinusitis (CRS) is a crucial and challenging entity in bone marrow transplantation candidates. We aimed to evaluate the diagnostic accuracy of the Sino-Nasal Outcome Test (SNOT-22) and Lund-Kennedy endoscopic score for the diagnosis of CRS in bone marrow transplantation candidates.
Materials And Methods: We conducted a single-center, observational study evaluating bone marrow transplantation candidates by paranasal sinus computed tomography (CT) scan without contrast to measure the Lund Mackay score.

Precise volumetric measurement of newly formed bone after maxillary sinus floor augmentation (MSFA) can help clinicians in planning for dental implants. This study aimed to introduce a novel modular framework to facilitate volumetric calculations based on manually drawn segmentations of user-defined areas of interest on cone-beam computed tomography (CBCT) images MATERIAL & METHODS: Two interconnected networks for manual segmentation of a defined volume of interest and dental implant volume calculation, respectively, were used in parallel. The volume data of dental implant manufacturers were used for reference.

Unlabelled: Uremic leontiasis ossia (ULO) is a rare manifestation of renal osteodystrophy in) patients with end-stage chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPTH). It occurs due to increased osteoclastic activity secondary to high plasmatic parathyroid hormone (PTH) levels. This leads to bone deformation with thickening and massive enlargement of the cranial vault, resulting in a leonine face appearance.

Cardiac metastases from bladder cancer are extremely rare and typically associated with a poor prognosis. We here report a case of a 74-year-old woman who had been diagnosed with multiple bladder cancer and later developed pelvic recurrence and multiple bone metastases. Second-line pembrolizumab treatment achieved complete remission.

This article presents 582 bone scan images from 291 adult patients who attended the Nuclear Medicine Service at the Instituto de Investigaciones en Ciencias de la Salud (IICS) of the Universidad Nacional de Asunción (UNA), Paraguay, between 2020 and 2024. The images were acquired using trimodal SPECT-CT-PET equipment, model AnyScan SCP, and the MEDISO brand. Approximately 20 mCi of technetium-99m methylene diphosphonate (Tc-MDP) was administered to each patient, producing whole-body planar images in anterior and posterior projections of the axial and appendicular skeleton with a resolution of 256 × 1024 pixels.
