Physical performance of the Siemens E.CAM gamma camera

Elevated midbrain serotonin transporter availability in mixed mania: a case report

“…The dose was slowly injected into the right antecubital vein in a dimly lit and quiet room. Serial SPECT scans (5 min, 6 h and 24 h) were performed on a dedicated Siemens MultiSPECT 3 gamma camera with fan-beam collimators (Siemens Medical Systems; Hoffman Estates I11., USA) [11]. Head positioning was monitored during acquisition by using two position lasers.…”

“…The SPECT scans were decay-corrected and reconstructed with Butterworth-filtered back-projection in a 128 × 128 matrix with a pixel size of 3 × 3 mm, and were attenuation-corrected with Chang's algorithm [10,11]. The imaging resolution was 8–9 mm.…”

Uso da cintilografia miocárdica em repouso durante dor torácica para descartar infarto agudo do miocárdio

“…This patient's global and segmental left ventricular function was normal and he had a slight elevation of troponin I level (<10 ng/ml). The most likely explanation for these findings is that the myocardial area at risk was small, since the spatial resolution of tomographic scintigraphy in devices as the one used in our study is approximately 10x10x10mm 19 . Some imaging studies have shown that approximately 13% of the subendocardial infarctions with normal ECG are detected by magnetic resonance, but they are below the resolution cutoff value of the gamma camera 20 .…”

Intraoperative sentinel node imaging versus SPECT/CT in oral cancer – A blinded comparison

“…Immediate planar imaging was performed using a dual head gamma camera (e.cam, Siemens Healthcare, Munich Germany) using a low energy highresolution collimator with 9.1mm resolution [32]. Dynamic images were taken in the anterior or oblique view (20 x 60s, 128 x128 matrix).…”
