Figures
- FIGURE 1.
A 62-y-old patient with larynx cancer. (A) Head and neck CT image of patient showing transaxial (left), sagittal (middle), and coronal (right) slices. (B) Head and neck 99mTc-glucarate SPECT image. (C) SPECT/CT fusion image. CT images show thickening of soft tissues of left side of subglottis with eccentricity and luminal stenosis. Fusion images show intense focal uptake in that region.
- FIGURE 2.
A 65-y-old patient with clinical suspicion of local relapse from previously resected sclerosant basocellular epithelioma in right nasogenian fold. Patient underwent right maxillary antrectomy. (A) CT images show surgical sequel at roof of right maxillary sinus with mucosal thickening of cavity. (B and C) 99mTc-glucarate shows intense uptake (B) that in fusion images corresponded to location of pterigomaxilar fossa (C). Lesion was further confirmed as local relapse by biopsy.
