Prognostic Value of Resting Left Ventricular Sphericity Indexes in Coronary Artery Disease With Preserved Ejection Fraction.

Background: Adverse left ventricular remodeling is a significant cardiovascular predictor for patients with coronary artery disease and preserved left ventricular ejection fraction (LVEF). However, the remodeling indexes reflecting left ventricular spherization by myocardial perfusion imaging are underexplored.

Methods And Results: 727 patients (mean age 59.

Delayed epiphyseal closure in an adult with panhypopituitarism detected by Tc-MDP bone SPECT/CT.

We reported a 23-year-old male patient with panhypopituitarism who underwent two resections for craniopharyngioma and received postoperative hormone replacement therapy. The Tc-MDP bone scan revealed focal high uptake of radioactive nuclide in multiple large joints. The SPECT/CT demonstrated the focal high uptake in their metaphysis.

A case of accidental local pulmonary Tc-MDP uptake on bone SPECT/CT.

We report a case of accidental local Tc-MDP uptake in left lung on bone scan without pulmonary parenchymal abnormality on SPECT/CT. The abnormal uptake disappeared on repeated bone scan and SPECT/CT after 3 days. It is speculated that the high radioactivity focus is a microthrombus in pulmonary artery.
