Abstract:
A 58-year-old woman was referred for right wrist pain, with suspicion of stress fracture of the radial styloid. 99m Tc-HDP bone scintigraphy, using new 3D-ring CZT system, was performed. Blood pool SPECT/CT revealed intense hyperemia along the first extensor compartment of the right wrist, suggesting De Quervain tenosynovitis, while late-phase SPECT/CT showed right thumb arthritis. Ultrasound imaging confirmed De Quervain tenosynovitis. Our case highlights the potential of blood pool SPECT/CT using new 3D-ring CZT system to detect relevant extraosseous findings, especially common tendinopathies such as De Quervain tenosynovitis.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
