To comparatively study the sensitivity and specificity of 67Ga planar and SPECT images in diagnosis of non-Hodgkin’s lymphoma. Methods Simultaneous 67Ga planar and SPECT were conducted by using Sopha DS7 SPECF for 48 intermediate lesions in 30 patients that had been pathologically confirmed, with their healthy counterparts as controls. Results Thesensitivity of planar images in head-neck, chest and abdomen was 60.0%, 72.7% and 72.7% respectively, and that of SPECTwas 93.3%, 90.9% and 81.8% respectively. The planar imaging had a general false-neck rate of 31.3%, 2.5 times higherthan SPECF imaging (12.5%) had. Both of them had the same false-positive rate (6.3%). Conclusion SPECT imaging is superior in sensitivity to planar imaging for head-neck, chest and abdomen in detection of intermediate NHL.
