SIR, We developed a multipinhole SPECT (MPH-SPECT) imaging system with up to 20 pinholes leading to a spatial resolution <1 mm and increased sensitivity by a factor of up to 50 compared with conventional bone scintigraphy (BS) [1]. Recently, we have demonstrated that MPH-SPECT represents a feasible tool for the study of osseous alterations in IL-1 receptor antagonist-deficient mice [2].
We report herein an initial clinical study with this newly developed method by imaging the clinically dominant hand of 13 early RA patients (ERA group, disease
