Do Negative <sup>124</sup> I Pretherapy Positron Emission Tomography Scans in Patients with Elevated Serum Thyroglobulin Levels Predict Negative <sup>131</sup> I Posttherapy Scans? Open
In our selected patient population, (131)I posttherapy scans are frequently positive in patients with elevated serum Tg levels, a negative diagnostic (131)I or (123)I scan, and a negative (124)I PET scan. Thus, for a patient with elevated …

Positron emission computed tomography using large area detectors Open
The use of large area, position sensitive devices for positron annihilation coincidence detection permit fully 3-dimensional reconstructions of the activity distribution. Since the detectors may remain stationary or be rotated during the s…
