- FIGURE 1.
(A) Baseline 18F-FDG PET study with warmed blankets and increased room temperature demonstrated marked BAT uptake. (B) Postchemotherapy follow-up 18F-FDG PET study in same patient with warmed blankets, increased room temperature, and 10 mg of diazepam demonstrated elimination of BAT uptake.
- FIGURE 2.
(A) Baseline 18F-FDG PET study with warmed blankets showed marked uptake in the neck, supraclavicular, mediastinal, and paravertebral regions suggestive of extensive BAT uptake. (B) Three-month study with warmed blankets showed no change from baseline. (C) Six-month study with warmed blankets prospectively showed no significant change from baseline but retrospectively showed apparent increase in focal uptake in right upper chest. (D) Nine-month study with warmed blankets and diazepam showed suppression of BAT uptake and clear demarcation of focal disease in upper right chest.

A 28-y-old man with desmoplastic small-round-cell tumor presented in October 2009 for initial 18F-FDG PET study (left) and subsequently in January 2010 (right). Both studies used approximately 270 MBq of 18F-FDG and were obtained after 60-min uptake phase. Initial image was obtained without warming techniques. Follow-up image was obtained with warming intervention. Apart from disease progression, presence and absence of significant BAT accumulation is noted. (Reprinted with permission of (1).)
