Primary cardiac osteosarcoma is a very rare malignancy with a high incidence of local recurrence and systemic metastasis, contributing to the poor prognosis. Radiological modalities are commonly used for the evaluation of cardiac masses. 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG) positron emission tomography/computed tomography is a valuable whole-body imaging modality in ...
OBJECTIVE In this part one of a two-part article, we aim to illustrate our understanding of and approach to comprehensive cardiac CT reporting, cardiac CT technique, and coronary calcium scoring CT, as well as normal and anomalous coronary artery anatomy. CONCLUSION Structured cardiac CT reporting is important to effectively communicate with referring clinicians. Knowledge of cardiac CT techn...
Metastatic tumors to the heart unlike primary cardiac tumors are not rare. Despite its frequency, cardiac metastasis is commonly detected only during autopsy as the symptoms of disseminated metastasis prevail over symptoms caused by cardiac metastasis and hence is overlooked most of the time. Tumors more commonly found metastasizing to the heart are malignancies of lung, breast, esophagus, lymp...
Background and Objectives: Iran is a large country that is often an importer of major medical equipment. There is no comprehensive databank of the status of the equipment in the country. The present study provides a clear description of the dispersal status of major medical equipment in the country in 2016 and the estimated number of required devices in 2026. Methods: This study was conduct...
Cardiac imaging with multiple-row detector computed tomography (CT) has become possible due to rapid advances in CT technologies. Images with high temporal and spatial resolution can be obtained with multiple-row detector CT scanners; however, the radiation dose associated with cardiac imaging is high. Understanding the physics of cardiac imaging with multiple-row detector CT scanners allows op...
