Osseous hemangiomas are usually asymptomatic. Symptomatic hemangiomas are rare and represent approximately 1% of all cases. Hemangiomas usually present as photopenic defects in methylene diphosphonate (MDP) bone scintigraphy. MDP uptake in vertebral hemangiomas is extremely rare. We report a 20-year-old woman who presented with upper back pain. MDP bone scan showed focus of MDP uptake in the seventh dorsal vertebra. SPECT/CT localized the uptake to vertebral body and transverse process with CT findings suggestive of hemangioma. Further, MRI also confirmed hemangioma in the same location.

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.

Background: Tc-stannous methylene diphosphonate (Tc-MDP) bone single-photon emission computed tomography/computed tomography (SPECT/CT) imaging plays a crucial role in various clinical applications. Many strategies have been developed to reduce the injection activity and procedure time, improve the patient experience and reduce their anxiety prior to and during SPECT imaging. This study aimed to evaluate the SwiftScan mode and its effect on image quality, and diagnostic performance of malignant skeletal lesions in bone SPECT image.

The primary aim was to evaluate the prolonged quality characteristics of methyl diphosphonate (MDP) aliquots during ambient storage over a specified duration. This study further investigated potential additives that could enhance the stability of MDP aliquots stored under such conditions. This was a laboratory-based experimental study conducted at the University Teaching Adult Hospital in Lusaka, Zambia.

Phyllodes tumors (PTs) are rare fibroepithelial tumors accounting for less than 1% of all breast neoplasms. They are malignant in 20% of cases. Only a few cases of malignant PT metastatic to bone have been reported.

Introduction In nuclear medicine, there is a critical need to balance the control and optimization of radiation doses to ensure patient safety while achieving high-quality diagnostic outcomes. However, diagnostic reference levels (DRLs) for nuclear medicine imaging studies have not been established in India. This study aims to fill this gap by establishing institutional DRLs and assessing radiation dose data specifically for Nuclear Medicine SPECT examinations.
