Simultaneous whole body 18F-fluorodeoxyglucose positron emission tomography magnetic resonance imaging for evaluation of pediatric cancer: Preliminary experience and comparison with 18F-fluorodeoxyglucose positron emission tomography computed tomography

Figure 5 18-year-old male with nodular sclerosing Hodgkin’s lymphoma. Axial T2-weighted MRI images of the chest (A) and abdomen (B) demonstrate enlarged mediastinal lymph nodes (white solid arrow) and a region of hypointensity within the spleen (white dashed arrow). Axial images from the concurrently obtained PET examination (C and D) demonstrate intense radiotracer uptake within the mediastinal lymph nodes (solid black arrow) and spleen (dashed black arrow). Axial ADC map images through the same regions (E and F) show areas of decreased signal intensity corresponding to the areas of radiotracer uptake (arrowhead and curve arrow). PET: Positron emission tomography; MRI: Magnetic resonance imaging; ADC: Apparent diffusion coefficient.
