Gated Tomographic Radionuclide Angiography Using CZT Gamma Camera in Patients Receiving Cardiotoxic Chemotherapy Going Faster and Less IrradiatingBailly, Matthieu, MD*; Le Rouzic, Gilles†; Metrard, Gilles, MD*Clinical Nuclear Medicine: June 2019 - Volume 44 - Issue 6 - p 472–474 doi: 10.1097/RLU.0000000000002569 Interesting Images Buy Abstract Author InformationAuthors Article MetricsMetrics Tomographic radionuclide angiography (TRNA) can monitor cardiac function in patients receiving cardiotoxic chemotherapy. Gamma cameras using CZT detectors enable dose reduction and quicker acquisitions. We report 80 patients who underwent a 7-minute TRNA acquisition after injection of 550-MBq 99mTc–labeled human serum albumin. Data were analyzed full and half. Image quality was not visually decreased. There was no significant difference in left ventricular systolic and diastolic volumes and in left and right ventricular ejection fractions between full and half data acquisitions (P < 0.0001). When injecting half activity, effective dose could be reduced to 1.92 mSv. From the *Nuclear Medicine Department, and †Radioprotection Department, CHR Orleans, Orleans, France.
